After extracting oil and gas from the ground, you have to accurately measure and weigh how much you have extracted using weighing systems like an industrial weight scale. Accurate weighing and measurement ensure that you get paid the right amount.

In this article, we’ll talk about all you need to know about measurement in the oil and gas industry.

Things you must know about measuring Oil & Gas Production

  • Initial Measuring Process of Crude Oil

Crude oil generally contains sediment, seawater, and several impurities when extracted from the ground. Before measuring it, crude oil must be put through an onsite filtering process, which removes the sediment and impurities. The output is then measured using a weighing system.

  • Measuring Crude Oil

Smaller amounts of crude oil are measured as the transport tanks are filled. Truck scales are mostly used for this purpose.

Larger volumes are measured by valves that record the volume as it enters the pipeline. You need to measure and record the initial volume.

  • Weighing Natural Gas

Natural gas is measured using a device installed in a gas pipeline where the gas is being extracted. The meter will record the volume and pressure, allowing you to determine the amount of natural gas.

  • Oil and Gas Measurement

Crude oil and gas are measured before leaving the well site. Oil is measured in barrels (bbl). Gas production is measured in cubic feet and is reported in million cubic feet (Mmcf), billion cubic feet (Bcf) or trillion cubic feet (Tcf)

You will be paid based on the initial measurement of the product. So, ensure that you use the right weighing system that will measure accurately.

4 Factors That Can Affect Weighing System’s Accuracy

  1. Load Cell Accuracy

Get a high-quality load cell to get accurate weighing. The load cell converts the mechanical force into an electrical signal. This signal is measured by the strain gauges that are bonded at points on the cell.

If you apply the load at the proper spot on the load cell, the strain gauges will provide a proportional electrical signal. Check the response time of the load cell for further accuracy.

  1. Load Factors

Apply load to each load cell in the weighing system like truck weight scale as specified by the manufacturer. For accurate weighing, only the load cells must support all the weight that you want to measure.

Align the load point assembly correctly to ensure that the mounting hardware channels the load directly through the load cell. The level of each load cell should be the same. Ensure that the floor beneath the load cells is strong enough to bear the weight of the load.

  1. Environmental Forces

The accuracy of the weighing system will be high only when the weight force is transmitted to each load cell. However, environmental forces acting on the load cell can also affect the load cell signal. These factors include large temperature variations, shock loading, pressure difference, wind loading, to name a few.

Try to eliminate or minimize as many environmental factors as possible to reduce errors in the load cell signal.

  1. Mechanical and Electrical Noise

The load signal must arrive at the weight controller in the cleanest form possible to ensure accuracy. As we discussed, the load cell transmits a signal that represents a mechanical force to an electrical signal. However, vibrations of the machinery are also a mechanical force that gets converted to electrical signals. Moreover, EMI and RFI are electrical signals that also get measured by the weight controller.

  1. Interference with Signal Transmission

Moisture and temperature can interfere with the signal transmission. Moisture can enter the weighing system’s junction box and attack each load cell. This will reduce the capacitance between the signal lines. This, in turn, will cause the load cell excitation lines to couple with the signal lines and create electrical noise. As we saw, any kind of electrical signal can affect the weighing accuracy.

Large temperature fluctuations can cause resistance changes in the cable. This will again cause excitation changes, leading to changes in load cell signal.

Eliminate as many mechanical and electrical noise sources as possible to improve the weighing accuracy.

Taking Care of Industrial Scales

In the oil and gas industry, measurement is critical and is done every single day. If you take care of the scales, you can be sure of getting accurate results. Here are some ways you can make sure you get accurate results:

  • Keep the Foundation Free of Debris: Debris and dust might accumulate through the day. It is essential that you remove this debris regularly to avoid inaccuracies in weight measurements. You can use a pressure sprayer to clean the scales but ensure that the load cells and junction boxes can withstand that pressure. If it damages the equipment, the measurements would be incorrect.
  • Conduct Regular Inspections: Keep an eye out for anything that seems out of place. Look for corrosion, wear and tear, or signs of damage. Inspect the junction boxes, wiring and hardware of the system. Look for signs of moisture inside the electronics. Regular inspections will give you the confidence that the weighing system is functioning properly. This way you can be assured of accurate measurements of oil and gas production.
  • Keep the Scale Grounded: Keep the scale grounded as a basic defense from lighting and power surges. Connect the scale to the manufacturer’s grounded system. If the ground connection is disrupted, it will shunt the power surges to other places like load cells and scale electronics, causing a lot of damage.
  • Make Important Adjustments: Industrial scales can expand and contract a little at different times of the year. Therefore, you need to make the necessary adjustments for thermal expansion so that you get accurate readings. Ensure that the scale is giving accurate measurements by testing it with certified weights.

Regular maintenance of industrial scales won’t just give you accurate readings but also prolong the life of the scales. Choose the right equipment and weighing scales that can withstand the harsh conditions of the oil and gas industry.

Offshore Oil and Gas

When fossil fuels formed under the pressure of newly emerging rocks, they formed in a world that was geologically very different from today’s world. Where there were seas, there is now land and vice versa. As a result of these processes, a lot of the oil and gas the world uses today comes from offshore deposits. Most of the undiscovered oil and gas resources today are also located under the seafloor of the world’s oceans. For the extraction of hydrocarbons, the oil industry has developed a whole branch of exploration and production, targeting these offshore deposits.

A History of Offshore Drilling

Offshore drilling began not long after onshore drilling. According to some sources, the earliest offshore wells got drilled in the Grand Lake St Marys in Ohio, in 1891. These wells got drilled in shallow water from platforms standing on piles. The first salt-water offshore wells, according to the American Oil and Gas Historical Society, were built in 1896, in the Summerland oil field in California. Those wells were, too, constructed in shallow water. In fact, until the late 1940s, no company dared drill further than a few hundred feet off the coast.

What oil producers did then was build piers into the sea and mount ordinary onshore rigs on them. Images from that time show rows of piers extending into the sea, dotted by oil rigs. That changed in 1911 when the Gulf Refining Company drilled an oil well in Caddo Lake in Louisiana without using a pier. Instead, it used tugboats and barges, and floating drivers for the piles on which it erected the rig. Other wells in the vicinity soon followed.

The prototype of what we now call a fixed oil platform came more than 20 years later. In 1938, an engineering firm called Brown & Root Marine Operators built a wooden platform a mile from the Louisiana coast with wooden pilings driven into the seafloor to keep it in place. A hurricane proved the structure was not all that stable in 1940 but the Creole platform got rebuilt following the hurricane and production continued.

The first offshore oil well to get drilled out of sight of land came in the late 1940s, also in the Gulf of Mexico, as it began to take the shape of the major producing region we know today. At 10 miles from the coast, the Kermac Rig No. 16 stood in about 20 feet of water, and it withstood the hurricane that hit the Gulf of Mexico just a week after the rig was installed.

Since the 1940s, offshore drilling technology has been improving consistently, and today we have the technology and equipment to explore for and extract oil and gas from even ultradeep waters economically.

Offshore Exploration

Before drilling begins at an offshore location, exploration and production companies conduct a series of surveys to determine whether drilling would be justified. Offshore oil and gas production, despite the progress made in technology and cost reduction, is still more expensive than most conventional oil and gas operations onshore, so preliminary exploration is even more critical offshore than onshore.

Magnetic surveying and gravity measurements are conventional means of determining what sort of rocks lie underneath the seafloor and what the chances are of those rocks bearing oil and gas.

Magnetic surveying involves detecting anomalies in the intensity of magnetic fields in sub-seafloor rocks that may indicate the presence of what petroleum engineers call oil and gas traps.

Gravity surveying focuses on one property of rock formations: density. Since the denser a rock is, the less likely it is to be reservoir rock, data about the density of different rock layers can also tell explorers how likely it is for a particular segment to hold oil and gas.

Seismic surveying, of course, is also an integral part of offshore exploration. It involves sending shock waves into the rock under the seafloor and recording the time it takes for it to return, reflected or refracted, and give the drillers data about the properties of the geology.

The combination of these methods as well as sampling cores from the rock helps establish whether the likelihood that oil and gas being present in the rock is high enough to justify drilling an appraisal well. If the answer is yes, exploratory drilling begins.

Offshore Drilling Equipment

For the most part, offshore drilling requires the same equipment as onshore drilling. A rig, a drillstring with a drillbit at the end, and a turntable are the essential equipment for drilling. (Along with a power source and the drilling mud that facilitates drilling by cooling and lubricating the drillbit).

A blowout preventer that is a critical component of an onshore wellhead is even more critical in offshore drilling because, unlike onshore, it is hundreds, often thousands of feet below the surface of the sea or ocean and a lot more challenging to access for maintenance or repairs.

There are also several pieces of equipment that are special to offshore drilling. These include:

Templates: Subsea templates are steel structures that play the role of a foundation for other structures at the bottom of the sea, including wellheads, Christmas trees, and manifolds.

Manifolds: These structures are installed at the wellhead to transfer the oil and gas from it to the subsea pipelines that will carry them to the shore or the floating, production, and storage vessel.

Marine riser: The riser is a steel pipe that connects the wellhead and the BOP to the surface to keep the drilling mud flow cycle going. Without a riser, the mud once flushed down into the wellbore would just spill out rather than return and be reused.

Drillship for offshore drilling

This is a drillship, a wonder of modern technology considering the depths it’s capable of drilling in.

Drilling Rigs

Offshore drilling rigs get broadly divided into two groups: fixed and floating. Within these groups, there are several types of rigs.

Fixed platforms include barge rigs, jack-up rigs, and tension leg platforms.

Barge rigs get used in shallow waters of no more than 20 feet and other damp environments but not in deep water. They are fixed to the bottom of the basin via anchors or submerged to rest on the bottom.

Jackup rigs are the most common offshore drilling rigs that feature support legs. These can be either open-truss legs — steel structures similar to electrical towers — or columns, also made from steel. Column legs are cheaper to produce than open-truss legs, but they are less stable, which confines their use to depths of up to 250 feet, while jack-ups with open-truss legs can get used at depths of up to 350 feet.

The jack-up rig floats to the drilling site with its legs raised, and once it reaches its destination, these are lowered — jacked down — to fix the rig to the seafloor. While this fixing takes place, the drilling equipment gets automatically jacked up to the above-surface part of the installation. Once drilling is complete, the legs of the jack-up rig get raised again, and it floats to the shore or the next drilling location. This ease of use is what has made jack-ups so popular.

Tension leg platforms feature buoyant hulls for the topside — the part of the platform that is above water — and a system of “tendons”, or tension legs, that fix it to the seabed. These tension legs allow for horizontal but not vertical movements, which has made them popular in hurricane-prone areas such as the Gulf of Mexico. Meanwhile, the hulls, filled with air, keep the topside floating.

Floating rigs can be semisubmersible platforms, drillships, and floating production, storage and offloading vessels, or FPSOs.

Semisubmersible platforms, as the name suggests, are not fixed to the seafloor but only partially submerged and held in place by water ballast. There are two types of semisubs based on the way they are kept in place: bottle-type and column-stabilised.

Bottle-type semisubmersibles have hulls in the shape of bottles below the deck. These are filled with water to keep the platform in place.

Column-stabilised semisubmersibles feature, in addition to the water-filled hulls, a system of columns that connect the hulls to the deck, i.e. the hulls are not directly welded or bolted to the deck.

Both types of semisubmersibles are also anchored to the seafloor to stay in place. They can drill in water depths of up to 5,000 feet and are suitable for drilling locations with harsh weather as their semi-submerged state enhances their resilience to winds and waves.

Drillships can get used in depths of over 10,000 feet, which makes them the only suitable option for ultradeep offshore oil and gas deposits. They are also autonomous in terms of movement from one drilling site to the next one, unlike the other types of drilling platforms.

Because they get used in ultradeep waters, drillships need extra attention to stabilisation. This attention, in addition to the mooring, comes in the form of dynamic positioning systems, or DPS. A DPS involves several thrusters located at different points along the length of the drillship. These move to compensate for wave and wind movement directed by an onboard computer. Mooring is used in relatively shallow waters, while DPS gets deployed at ultradeep drilling locations.

FPSOs take over after the drillship finishes. These are vessels that take in oil and gas from several wells and accommodate production and processing equipment on deck along with storage capacity in the hulls. The oil and gas are kept there before being taken to the shore. That can happen via pipeline (for gas), or by loading oil onto another vessel to transport it to the coast. If there is no pipeline for the gas, it is either flared or injected back into the wells to boost production.

FPSOs can be moored to the seafloor either centrally, in a way that allows them to rotate in response to changes in the weather, or from the bottom up, meaning from multiple locations on the seafloor. Their multifunctionality is the best and most cost-effective option for offshore fields in areas without any oil production and transportation infrastructure.

Drillships and FPSOs are likely to become even more popular in the coming years and decades as the world’s more easily accessible offshore oil and gas deposits get depleted, and E&Ps push further out at sea in search for commercial reserves.

Most significant Offshore Fields and New Discoveries

It is hardly any surprise that four of the five largest offshore oil fields in the world are in the Middle East. Russia, Brazil, the United States, and Norway have also made a name for themselves as home to some of the largest fields, and tiny Guyana may soon join these ranks, too.

The biggest offshore oil field in the world is the so-called Marjan Complex in Saudi Arabia. It has 17.24 billion barrels of oil equivalent in remaining reserves, according to a ranking by Offshore Technology. It comprises several fields but is viewed as a single producing area.

Next is the Safaniya field, also in Saudi Arabia. It has 17.14 billion barrels of oil equivalent in remaining reserves. Its average daily production capacity is over 1 million barrels.

The Zuluf field, another of Saudi Arabia’s giants, has remaining reserves of 11.37 billion barrels of oil equivalent, of which over 11 billion barrels are petroleum and other liquids.

Fourth on the list of top offshore fields is Upper Zakum, in the UAE. Upper Zakum has remaining reserves of 11.064 billion barrels of oil equivalent.

Next is an entrant from Kazakhstan. The Kashagan oil field in the Caspian Sea has recoverable reserves estimated at between 9 and 13 billion barrels of oil and production rate of over 400,000 BPD.

Another giant offshore field that may hold up to 13 billion barrels of crude is Buzios, in Brazil’s pre-salt zone. The subsalt zone is currently contributing about two-thirds of Brazil’s total oil output from just three fields: Lula, Buzios, and Sapinhoa. Lula is pumping at close to 1.1 million BPD, with Buzios at more than 440,000 BPD, and Sapinhoa at some 203,000 BPD.

Looking forward, the star of offshore drilling is no doubt Guyana. Thought the tiny South American country only recently became visible on the international oil map after Exxon and Hess made a string of discoveries in the Stabroek Block that have brought the total reserves to an estimated 6 billion barrels and change. Discoveries are being made in other parts of the Guyana continental shelf as well.

In gas, the largest producing deposit remains the North Field/South Pars that Iran and Qatar share. Qatar recently lifted a moratorium on production expansion at the North Field in a bid to maintain its number-one status as LNG exporter and Iran is trying to increase production from South Pars as well, despite sanctions.

Australia and the U.S. Lower 48 have become a force to be reckoned with in natural gas and LNG in recent years, too. Australia even overtook Qatar as the world’s largest LNG exporter at one point last year and is striving to do it again, even at the expense of a gas shortage at home.

Russia is announcing new oil and gas — mainly gas — discoveries, too. This year alone it reported new oil and gas discoveries of 1.5 billion barrels of oil equivalent in the Arctic. Developing these reserves, however, will be challenging because of concerns about the changing climate.

The Economics of Offshore Oil and Gas

Offshore drilling is more complicated than onshore drilling because of the environment, so it is no wonder costs are substantially higher. As of 2018, the cost of deploying a drilling rig offshore was as much as 15 to 20 times higher than the costs associated with drilling an onshore well. Yet E&Ps are working on those costs and have managed to reduce them. They have also shortened drilling times and the times from striking oil to beginning production, which accelerates the start of the payback period on what is invariably a substantial investment.

Offshore drilling is unlikely to become cheaper or even as cheap as onshore drilling in some parts of the world, at least. Still, it is becoming more efficient as is exploration, in large part, thanks to advanced surveying and drilling technology. That contributes to lower costs and makes more projects viable, even in deeper waters. These advancements will ensure a continual supply of competitive oil as legacy producing fields near depletion.

How Smart Hard Hats Improve the Safety and Efficiency of Oil & Gas Workers

The oil and gas industry, being one of the oldest participants in the industrial revolution, has seen a lot of disruption in the technological arena. Whether it’s in identifying, extracting, or producing raw materials on offshore or onshore operations, or downstream services like fuel delivery to the consumers, the industry has witnessed a significant evolution. Both Onshore and Offshore oil rigs are implementing the latest technologies in the form of new types of equipment such as hoisting systems, cranes, turntables, pumps, and large engines.

Additionally, E& P companies are integrating IoT enabled devices that monitor and keep track of every operation seamlessly. Downstream companies are adopting on-demand fuel delivery services to their business strategy.

In this article, we’re going to shed some light on a much-discussed, and widely adopted IoT enabled technology called – the smart hard hat! We’ll cover each aspect of the smart hard hat and how it is taking its place in the O+G industry. We’ll also understand why implementing this tech into oil fields would lead to increased safety and efficient operations.

With further ado, let’s start and explore this pioneering technology.

Why Do Smart Hard Hats Deserve Their Inclusion in Oil & Gas Sites?

Exploration & Production (E & P) companies are usually associated with heavy machinery & operations that require special attention and frequent maintenance. Notably, in any upstream operations, workers’ safety is an important matter.

Upstream operations pass from finding hydrocarbon reservoirs, drilling oil and gas wells, and extracting raw materials to selling them to be refined by other companies into products such as gasoline, which demands meticulous monitoring of operations. However, sometimes due to practical, procedural and operational processes, it becomes gruelling to coordinate with your staff and workers.

Here is where smart hard hat comes in!

What is a Smart Hard Hat & How Does it Work?

Smart Hardhat’ as the name suggests is a smart device that could help company owners and workers in many ways. The whole device gets embedded with sensors that track surrounding quantities and measures the data accurately for the betterment of its wearer and the one who is monitoring. These sensors can be anything from a temperature tracker to an air quality checker.

A smart hardhat is awash with various sensors like a smoke detector, barometer, SOS panic, gyroscope, body temperature sensor, GPS, and humidity sensor. Sensors continually detect particular quantities and send a signal to the owner as well as its admin – whether the controlled parameters are out of their defined range or not! If any parameters indicate a variance beyond safe limits, the signal triggers alert to the wearer and administrator about the situation. Hence, many hazardous incidents can be avoided.

Management Software


Here is how these sensors work!

  • Temperature Sensor: This sensor lets the smart hardhat track the temperature variation of surrounding the area. It continually sends the signal about the changes happening in the temperature.
  • Humidity Checker: As the name suggests, the sensor facilitates in knowing the moisture in the air. Therefore, if at the site, specific humidity is required, a smart helmet helps to monitor that.
  • GPS: Today, most smartphones utilize GPS to give you the exact location of your interest. This GPS module tracks the wearer precisely.
  • Map Navigation: Workers in the oil field, especially new ones, can navigate their way through the site very quickly using the navigation capability of the smart hardhat.
  • SOS Panic Button: The panic button installed on the device comes to aid when there’s any medical emergency.
  • Proximity sensor: This sensor helps the wearer to stay away from the objects that they’re not allowed to touch or risk going near.

This hardhat works on IoT (Internet of things) technology where software, network connectivity, each device continually communicates with each other without any human interaction. They get connected through any internet connection, and as stated earlier, it adjusts its values according to the situation.

What is the Role of IoT Enabled hardhat in the Oil & Gas industry?

As we mentioned earlier, the smart hardhat comes handy in safety issues and the need for effective resource management. The benefits of a smart hat don’t stop here. It also monitors the health of your valuable workers.

If a worker is heading unknowingly toward a restricted area or any dangerous place in the site, it would instantaneously alert him about it. Nowadays, these devices get furnished with groundbreaking headsets. That allows the workers to communicate efficiently through their reporting authority as well as related workers. It also reduces the unwanted noise that’s coming from the site.

The panic button installed on the hat lets people take precautions in case of any emergency. 

Respiratory hazards can also get avoided by forecasting any leakage or defect in any of the instruments at gas sites. Workers could save themselves getting in contact with dust, fumes, mists, gas, smoke, sprays, vapours, or other hazards.

It’s not only manual workers, but E& P company management can also find smart hard hats promising due to their resource management capacity.

There are hundreds or even thousands of workers in each company working on onshore and offshore sites at their allocated location. To manage each and everyone could be challenging for any manager. For higher production and output in the oil field, effective monitoring and management become vital. A smart hard hat comes as the best solution for this situation. You might ask how?

Well, the smart hardhat gets integrated with GPS modules that always sends a signal to the software that is managed by the higher authority person on the site. So every wearer can be tracked with their live location. A manager will be able to identify a particular worker and know whether he is at his allocated work location. Or if he is idling away his time doing unnecessary things — any extra insights into these kinds of data aids in better management of assigned workers.


By 2025, it’s forecasted that there’ll be more than 21 billion IoT devices. More and more industries are adopting these IoT enabled solutions to enhance their businesses. The oil & gas industry will be one of the most affected sectors by IoT and other technologies. The smart hard hat has penetrated in multiple areas where safety and management is the prime concern. It remains to be seen how soon upstream and midstream companies install such technology for their betterment.

Pressure, Volume, Temperature (PVT) Tests Offer Valuable Insights

PVT tests are an essential part of the exploration and production process. The behaviors of reservoir fluids are nothing short of complex, but for oil and gas exploration projects to reach an optimal outcome, companies need to understand these unique behaviors so that they can make data-driven engineering decisions. A PVT (pressure, volume, temperature) analysis takes a deeper dive into the behaviors of a reservoir’s fluids to collect this essential data that will advance your project to the next phase.

True to the nature of the oil and gas industry, the amount of time required to extract the hydrocarbons from the subsurface will directly impact the cost of the well (more time = higher costs). Because oil and gas companies have no control over the commodity pricing of the market, experiencing increased costs will reduce the overall profit margin for each project.

In response, companies can determine the properties of the oil and gas contents in the reservoir to discover how hydrocarbons flow from the well, which will allow operators to determine the most cost-effective methods for extraction.

In essence, the PVT analysis looks at the way a specific reservoir’s fluids behave under certain conditions. The results of the study serve to answer critical business questions, including

  • What is the volume of crude oil and gas in the reservoir?
  • How can we optimize the liquid recovery process?
  • What are the unique flow properties of this reservoir?
  • What do we need to know to maintain the pressure?

PVT Tests and Analysis are conducted by a professional petroleum service provider that can not only collect the essential data but also provide insight and guidance on next steps.

Pressure Volume Temperature Analysis (PVT): A Brief Overview

Companies can perform a PVT analysis for any stage of the hydrocarbon extraction process. This method collects samples from specific well sites to study so you can make decisions based on your unique data, not just industry standards. As a result, PVT Analysis has made it easy to understand how reservoir fluids behave so engineers can maximize the hydrocarbon recovery process at a minimal cost.

Here’s a closer look at what a PVT Test and subsequent Analysis entails:

Finding the Bubble Point

To fully understand the mechanics of fluids in an oil well, we perform a test to find the bubble point of the sample fluid. This is a major component of a PVT Analysis that allows us to understand the characteristics of the reservoir.

Geologists will use the results of the bubble point test to determine information related to the expected recovery of oil in the well. If the oil to be recovered is undersaturated (i.e. contains very little dissolved gas), then only a small percentage of the oil can be recovered without the intervention of advanced tools or other methods. This can have a significant influence on the overall operating costs of the well.

Differential Liberation

PVT Analysis examines the differential liberation process, where the gas is separated from the liquid sample in a continuous cycle. Because the pressure is reduced gradually, the gas doesn’t reach equilibrium with the liquid.

Flash Liberation

A PVT analysis will also look at the flash liberation process. This occurs when a sudden drop in pressure causes the crude oil to separate into an oil and gas mixture quickly.

Understanding the Reservoir to Surface Volume Relations

Though the bubble point test is a critical component of a PVT analysis, there are additional steps and measurements to take that will help to determine the best way to move forward.

The results of the flash liberation test and differential liberation test will yield three essential factors that will determine the relationship between the reservoir to surface volume: the oil formation volume factor, gas formation volume factor, and solution gas to oil ratio.

Let’s look at each one:

Oil Formation Volume Factor

This factor represents the ratio of the volume of oil at the reservoir conditions to that of the surface conditions.  The results are used to convert the flow rate of the oil at the surface to that of reservoir conditions.

Gas Formation Volume Factor

Similar to the Oil Formation Volume Factor, the Gas Formation Volume Factor is the ratio of the volume of gas at the temperature and pressure of the reservoir compared to the gas at the temperature and pressure of the surface.

Solution of Gas to Oil Ratio

This ratio indicates the amount of gas dissolved in the oil or water at any pressure. This ratio increases linearly with pressure and reflects the oil or water and gas composition. For perspective, a light oil contains more dissolved gas than a heavy oil.

Compositional Analysis: The Ultimate Goal of Performing PVT Analysis

The main reason that oil and gas companies choose to drill a well is to turn the project into a revenue-producing asset eventually. However, the main complication in doing so is the fact that the value of the oil extracted from one well is not the same as the value of oil extracted from another well.

This can complicate the process of determining the valuation of a project, calculating an ROI, and deciding whether to move forward or seek another drill site.

The composition of the oil, which can be discovered with compositional analysis, is an essential piece of the process. The results from this analysis can help companies determine with greater confidence how profitable a play will be. Once completed, the analysis can help companies learn just how much of each type of petroleum product (e.g. gasoline, kerosene, diesel fuel, etc.) can be produced from a single barrel of oil from that particular well.

Also, every refinery is set up to produce specific types of crude oil. A heavy crude oil and a light crude oil have very different production processes, which means they each require different refining methods. On the surface, this may seem like a small concern, but the differences in oil composition and the wells from which they came can have a major impact on your profit margins.

Depending on your projects, you may need to investigate refining along the Gulf Coast, where refiners are geared toward heavy crude oils, or in places like Europe or the East Coast of the U.S., where refineries are set up to handle lighter crudes.

The post How Much Oil is Left in the World? appeared first on Drillers.

A black drum barrel pouring crude oil as a map of the world: Illustrating an article about how much oil is left in the world.

In the oil industry,

We can get our data from a variety of sources, from the largest government bodies to small independent niche oil supply monitoring specialists. The question of how much oil is left in the world has been speculated upon for a long as the industry has existed.

Just a couple of years before the 2008 financial crisis, peak oil supply was a popular topic, garnering a lot of headline space. Now, more than ten years later, it is peak oil demand that is bothering the industry. Meanwhile, the question of how much oil is left in the world continues to fascinate.

That oil, like coal and natural gas, is a finite resource is nothing new. It was this finite nature of fossil fuels that sparked the peak oil supply worry. Yet those worrying about peak oil did not factor in the continual improvement of exploration and extraction technology, and the development of new methods to tap these finite resources.

Future supply depends on current investment

Investment in these improvements and the application of new extraction methods, however, depends on oil prices, which, in turn, depend on numerous factors. And while it may sound counterintuitive, low oil prices tend to spur greater improvements in oil extraction as companies strive to boost the efficiency of drilling while maintaining—or even lowering—costs.

This is what we saw during the 2014-2016 oil price crisis. In the United States, this was not just a time of many bankruptcies as exploration and production companies with high production costs couldn’t survive the price pressure. It was also a time of innovation as those still afloat struggled to make more with less. Many industry observers today argue the so-called second shale revolution was to a great extent fuelled by that innovation drive.

It is precisely these improvements in exploration and extraction that make it hard to pin down exactly how much crude oil is left in the world. In 2016, for example, the U.S. Geological Survey estimated there were up to 20 billion barrels of undiscovered, technically recoverable crude oil in the Wolfcamp Basin. (Part of the Permian shale play). Two years later, the USGS revised this estimate to 46.3 billion barrels. In just two years, the extraction methods used in the U.S. shale oil industry had changed enough to make more than double the amount of oil that was technically recoverable in 2016 recoverable in 2018.

Yet, prices can also discourage technical improvements in oil exploration and extraction. They can deter exploration growth in general, which is another thing that happens when the industry cycle reaches a low point, and we witnessed it relatively recently during the 2014-2016 crisis.

Reserve replacement ratios

Every oil company keeps an eye on its reserve replacement ratio. That is the ratio between new oil the company discovers through exploration and the oil it produces. If the company wants to survive and remain profitable in the long term, it needs to maintain a reserve replacement ratio of at least 100%.

In 2015, the reserve replacement ratio of the seven Big Oil majors—Exxon, Shell, BP, Chevron, Total, ConocoPhillips, and Eni—fell to just 75%. As a result, energy consultancy Wood Mackenzie in 2016 warned the world might face an oil shortage of as much as 4.5 million BPD by 2035. To date, reserve replacement is at a 20-year low, according to Rystad Energy data; oil companies are replacing just one in six existing barrels with new discoveries.

There is also another metric related to the reserve replacement ratio that has a bearing on estimates of global oil reserves. This is reserve life: the period that an oil company can continue producing a stable amount of oil from its existing reserves. In 2017, according to a Reuters analysis, the reserve life of Exxon’s oil declined from 17 to 13 years, and that of Shell fell from 12 to 10 years.

Now for some hard numbers.

In its latest Statistical Review of World Energy, BP estimated the world had 1.7297 trillion barrels of crude oil remaining at the end of 2018. That was up from 1.7275 trillion barrels a year earlier and 1.4938 trillion barrels in 2008. In 1998, the world had 1.1412 trillion barrels in remaining reserves.

So, as demand has continued to grow consistently over the last 20 years, so has production and, counterintuitively, so have global oil reserves. Yet in that same statistical review, BP said these higher reserves would last us for just another 50 years: another metric oil companies use to measure their business sustainability.

Called reserves-to-production ratio, this simply means the oil reserves of a company—or a planet—at the end of any given year, divided by the production of oil during that year. The caveat here is that the R/P ratio only provides us with the length of time reserves will last if production continues at the same rate. In other words, the world would have enough oil for another 50 years if production remains at 82-84 million BPD, which it averaged in 2018.

This is unlikely to happen. Energy demand has been growing as consistently as oil production. While at the moment, demand is lagging behind supply, most forecasters expect this to change as the global population grows fast, and this leads to an equally rapid rise in demand for energy. Notably, demand for electricity is expected to expand by 62% by 2050, according to Bloomberg NEF. While a lot of the additional generation capacity will come from renewables, oil will continue to feature heavily in the global energy mix, which makes it safe to assume production will continue growing for some time.

As this happens, the work of oil companies will become more challenging because recoverability of oil reserves will worsen. This is yet another facet of oil exploration and production that has a bearing on the answer to that fascinating question: how much oil do we have left?

As in other human activities, oil extraction begins with the “easiest” parts of a deposit—the places where there is the most oil that is easy to pump out of the ground. As these sweet spots get exhausted over time, producers need to tap harder to access reserves, which cost more to develop.

Again, the story of U.S. shale is a case in point. Thirty or forty years ago few companies, if any, paid any attention to shale because there was enough conventional oil. As that started to run out, E&Ps turned their attention to shale simply because there was no other alternative.

Deepwater exploration is another case in point. Offshore production has historically moved from shallow waters to ever-deeper deposits as natural depletion takes its toll. Onshore production has moved from conventional deposits to shale and oil sands, and from easy-to-access oil to more challenging fields.


So, as the difficulty level in oil extraction increases, so do costs. When these rise to a point when a company cannot extract the oil at a profit, the deposit becomes economically unrecoverable. Even if it remains technically recoverable, this is one more reason to take any global oil reserve estimate with a pinch of salt. Whatever technically recoverable oil the world has – is not all economically recoverable.

The amount of technically recoverable oil will probably continue to rise from year to year. Oilfield service companies continuously work to make exploration and extraction more reliable and more efficient. As for economic recoverability, this is a whole other matter. It depends on oil demand, and many believe oil demand is getting threatened by renewables—a threat that will only grow. We may well have enough oil to last us another 50 years. Whether this is time enough to wean ourselves off the fossil fuel before it runs out remains to be seen.

Rather than just the science, this post is focused on practical questions such as: What do petroleum engineers do? We cover the common job profile variants and tasks.

Different drill bits used in petroleum engineering

What is petroleum engineering?

Petroleum engineering is the branch of engineering that develops and implements ways of extracting crude oil and natural gas. Petroleum engineers play an essential role in every stage of the upstream process: they are the ones who evaluate the results of exploratory drilling and decide whether drilling a production well is commercially justified. Then they are the ones who find the most cost-efficient way to drill that well and monitor its performance once the oil starts flowing.

Petroleum engineers design the equipment that is used to pump oil and gas from the ground, and they are also the ones who devise ways to maximise production by employing various extraction methods. In addition to this, petroleum engineers are in charge of making sure the whole production process runs smoothly, and all equipment operates as it should. Finally, petroleum engineers evaluate the production from a well in terms of quantity and quality to make sure they are both optimal.

With so many responsibilities, petroleum engineering has several subdivisions that focus on different parts of the oil and gas extraction process.

Reservoir engineers are the experts who evaluate the oil and gas reserves of a deposit and determine the best drilling locations. Their job is to find out as much about the deposit as possible using geological survey data and testing results to make sure wells get drilled where there is the most oil and gas to be recovered, and that this gets done cost-efficiently.

Drilling engineers are in charge of the first stage in oil and gas production: well design, including the equipment to be used to drill the well, data analysis, well completion, and, eventually, abandonment. Drilling engineers’ work overlaps with that of completion engineers.

Completion engineers are in charge of taking a well from getting drilled to the start of commercial production of oil and gas. The completion engineer makes sure the well is built correctly, using the appropriate materials and equipment, and that it will operate properly as well.

Subsea engineers specialise in the planning and installation of any production and transportation equipment below the sea surface at an offshore platform. Rig installation, wellhead construction, and pipelines are the area of expertise of the subsea engineer.

Production engineers step in once the well is completed, and commercial production begins. The main focus of their work is two-fold: 1) monitoring the flow of oil and gas, and 2) Implementing methods for boosting that and improving the efficiency of production.

What qualifications do you need to become a petroleum engineer?

A bachelor’s degree in petroleum engineering is the basic qualification level you need if you want to start a career in this field. To prepare for that degree, focus on science subjects in high school is essential, with a side of social sciences to help develop communications skills that are also part of a petroleum engineer’s skill set as work involves extensive communication with various people and agencies.

Following the successful completion of a bachelor’s degree in petroleum engineering, many universities also offer a master’s degree in the subject area, and there are also additional qualification opportunities in the United States from the Society of Petroleum Engineers. The SPE awards certifications to those who complete its additional training course.

In the United States, in addition to completing a bachelor’s degree in petroleum engineering at any of the schools, one also needs to earn a state license if they are to work as self-employed engineers. The licensing procedure involves passing an exam and logging in four years of qualifying work. The process ends with another exam. There are also state-specific requirements.

In the UK, universities that offer petroleum engineering degrees require three A levels, preferably in maths/physics and sciences, as well as five GCSEs, also featuring maths and sciences. Some accept level 3 vocational qualifications, as well. For graduate and postgraduate degrees, a minimum 2:2 undergraduate degree in any of the following: chemical, civil, mechanical, and petroleum engineering, and earth sciences, is required.

For work offshore, petroleum engineers in the UK also have to pass an exam in basic offshore instruction and emergency training, or BOSIET.

Postgraduate qualifications are not necessary to enter the oil and gas industry as a petroleum engineer, but it’s worth noting many oil and gas companies do expect a postgraduate qualification, which also has an impact on pay.

After earning the required degree, a petroleum engineer would start work under supervision from a more experienced colleague. Additional training at the company is also a common practice for new engineers.

Those with a degree in chemical or mechanical engineering can also go on to specialize in petroleum engineering after earning a bachelor’s degree.

The skillset of a petroleum engineer

Problem-solving: all engineers are problem solvers, and petroleum engineers are no exception, especially since unsolved problems in this industry could be quite costly.

Analytical skills: problem-solving requires the ability to analyse vast amounts of data, and while automation is taking some of the load off, it is still up to the engineer to make sense of all that data and decide how to use it.

Mathematics: data analysis and problem-solving in engineering require an excellent versing in maths as a fundamental tool in everyday work. Whether it concerns oil well construction, oil flow improvement, or any of the dozens of other tasks an engineer has to perform in their work.

Communication skills: Oil and gas production is teamwork in a heavily regulated industry. What’s more, this teamwork involves expensive equipment and infrastructure. Excellent communication within the team and with relevant government agencies is essential for ensuring the success of projects that commonly cost tens of millions of dollars at the very minimum.

IT skills: Information technology has become an integral part of the oil industry, and this part will only grow with the increasing adoption of big data analytics, automation, and artificial intelligence. In this context, IT expertise has become essential for petroleum engineers.

What does a petroleum engineer do?

  • Discover new oil and gas deposits.
  • Devise the best way to exploit deposits, including best drilling locations and the number of wells.
  • Design the equipment that will be used to drill the wells and extract the oil and gas.
  • Develop drilling and completion plans.
  • Monitor drilling and completion.
  • Monitor well flow and find ways to maximize it profitably.
  • Analyse well data and track daily costs.
  • Determine the optimal amount and method of injecting water, chemicals, and sand into the well to achieve higher flows at cost.
  • Recommend changes to extraction methods to boost cost-efficiency.
  • Develop enhanced oil recovery methods when necessary.
  • Continually evaluate well performance.
  • Make sure production operations comply with safety and environmental regulations.
  • Oversee well abandonment when its productive life ends.
  • Keep relevant stakeholders informed about progress, including management, contractors, and energy and environmental authorities.

How much does a petroleum engineer make?

Petroleum engineers are in strong demand despite a shift from fossil fuels to renewables in the energy industry. While there is demand for oil and gas, there will be exploration and production and petroleum engineers are essential in both segments of the upstream sector. Authorities and industry research companies are warning a talent shortage is emerging.

Petroleum engineers are already quite well paid in most countries, and the talent shortage will undoubtedly make them even better paid.

In the United States, the world’s largest producer of oil, the average salary ranges between a little over $100,000 annually to almost $120,000. Including bonuses and profit-sharing, the figure could increase substantially.

Hourly wages in the U.S. oil industry range from $36 to $90, depending on the state where the petroleum engineer is working, their experience, and the position they have at the company.

The highest-paying state, unsurprisingly, is Texas. According to data for 2015, Texas led the rank of highest-paying states for petroleum engineers with an average annual salary of $164,000. The oil industry is a dynamic one, and things change fast as oil prices vary. Still, Texas remains the hottest spot in the U.S. oil industry with its two colossal shale plays, so it will likely stay the best-paying state for petroleum engineers until the so-called second shale revolution runs out of steam. In evidence of this, new data from Indeed shows the average annual salary for a petroleum engineer in Texas was almost $137,000. That was 45% over the national average.

In the UK, petroleum engineer salaries average almost £52,000 annually, according to Indeed data. According to Prospects, the wages of a drilling engineer begins at between £25,000 and £45,000 and could reach £40,000 to £100,000, depending on the experience needed, and the size of the company employing them.

These salary ranges, however, are for engineers working full-time for an E&P. Self-employed engineers can—and often do—make a lot more. There is a striking difference between working for a large oil company full-time and working for it as a contractor or consultant. In the latter case, you could make a lot more (multiples of the employed take-home pay).

Jobs in offshore exploration and development, for example, are generally a lot more lucrative than onshore assignments. A subsea engineer on an offshore platform could earn anywhere between $75,000 and $188,000 annually. A drilling engineer employed on a deepwater rig could make up to almost $200,000 in base pay plus bonuses. Yet this is considerably less than what an offshore drilling consultant would make: $143,000 to $305,000.

Working overseas can also be more lucrative than working at home, even doing the same job as a petroleum engineer. Big Oil companies active across the globe pay generous compensation for working overseas in addition to the basic pay, any bonuses the engineer earns, and profit-sharing allocations. What’s more, they pay even more to contractors or consultants.

A drilling engineer working for one of the supermajors could make almost $80,000 working for the company in Saudi Arabia. As an independent contractor, however, the same engineer could make more than $300,000 working with the same company in the Middle East.

Profit-sharing additions are also worth mentioning when it comes to the money a petroleum engineer can make. In Saudi Arabia, for example, the average salary of a petroleum engineer is equal to about $70,500. However, this is just the principal salary. In addition to it, a petroleum engineer could make about $5,900 in bonuses and another $8,000 in profit-sharing allocations.

As in other industries, pay depends not just on location or contractual terms but on experience as well. The longer you have worked as a petroleum engineer, the more you would be paid. For example, in Indonesia, the starting salary for a petroleum engineer with zero to two years of experience is about $630 per month. However, an engineer with 15 to 20 years of experience would get $1,440 per month, and those with experience of over 20 years would get over $1,700 per month.

In China, work experience is the most critical factor for employers when they determine the pay of the petroleum engineers they hire. The pay difference between an engineer with up to two years of experience and one with experience of between two and five years is 46%: $2,240 a month for the former versus $3,270 for the latter.

Across the globe, a drilling consultant would make more than a drilling engineer on an offshore rig because of their supervisory responsibilities. To become a drilling consultant, however, you need at least ten years of experience, both as a permanent employee at an oil company and as a self-employed consultant. In short, experience pays well.

There has been growing concern recently that the profession of a petroleum engineer is dying out because of the shift to renewable energy. A lot of people are in two minds about whether to pursue petroleum engineering or another engineering degree. Indeed, over the long term, the industry might need fewer engineers than it required in the 1970s, for example. However, there is still a shortage of skilled petroleum staff looming over the oil and gas industry, and this means petroleum engineers will continue to be in demand for the foreseeable future.

How to fight the gender imbalance within the offshore oil & gas engineering sector

From the gender pay gap to increasing the number of females at the board table – gender equality has been making headlines for several years now. It’s fair to say in many situations gender imbalances are being addressed successfully. But, when it comes to the male-dominated maritime industry, gender inequality is less of a gap and more of a gaping chasm.

The Maritime HR Association reports that the gender pay gap in the industry is a staggering 45.7% – a particularly unhealthy number when you compare it to the national average, which itself still stands at 17.4% according to the Office for National Statistics. The data was extracted from a survey from HR Consulting, which revealed that female maritime workers earn an average of £16.50 per hour – compared to nearly double what their male counterparts earn, £30 per hour.

Progress in achieving gender parity is agonisingly slow, and if it continues at current rates, it will be another 200 years before we realise it. Happily, achieving gender equality in the sector has become an important focus for everyone in the industry – men and women. And with some powerful initiatives being put into place, it may be achievable in a far shorter time frame.

Why Does the Maritime Industry Need More Women?

Just two per cent of the world’s 1.2million seafarers are women – and when you take into account that 92 per cent of that minority are working within the cruising industry, you can see the scale of the problem.

In more recent years we have seen strides forward in increasing the numbers of females working onboard a cruise ship. But, while it has grown to around 20 per cent, the majority of these women are involved in the hotel and catering service – just a tiny 0.5 per cent are employed in the technical maritime profession.

In the past, a career in shipping for women may have been discouraged – after all, it was commonly held that females were the fairer sex and would struggle to carry out some of the tasks required. But, technological advancement and progress in the industry mean that now what’s needed is less of the heavy lifting and more of the heavy thinking. For the maritime sector to thrive, it needs fresh knowledge to drive innovation – and this is something that is not just the preserve of men. By recruiting for skills and experience over gender, the industry will be well equipped to take some giant strides forward.

There is also a wealth of evidence that suggests having women high up in the workforce can do wonders for a company’s performance while more women in Parliament leads to more legislation in key social issues like health, child support, anti-discrimination and education. As the International Maritime Organisation puts it: “The evidence is clear: equality for women means progress for all”.

What’s Being Done to Address The Problem?

Back in 1988, the International Maritime Organization (IMO) developed the first programme designed to promote the advancement of women in the sector. The key goal of Strategy on the Integration of Women in the Maritime Sector was to boost the presence of women in the workforce in developing countries, through education, training and knowledge transfer. Fast forward to today, and the IMO adopted the theme of empowering women for World Maritime Day 2019 – suggesting that women in shipping still have a tough deal.

In the UK, the Women in Maritime Charter was launched in September 2018, which is urging companies to agree to specific targets on gender diversity. And in the same year, the IMO approved an application from Women’s International Shipping and Trading Association (WISTA) – itself founded in 1974 – for consultative status. This crucial step forward means the Association now has an active voice within the global industry and can do much to advance women’s positions in maritime.

Gender Parity Is the Goal

To truly address the issue of gender equality, it’s vital to consider what the end goal needs to be. Success shouldn’t be measured by achieving a 50/50 split of male/females in the maritime sector. But instead, be measured by the ability for all – regardless of gender – to have the same opportunities to enter the profession. Access to training and education as well as employment opportunities and career advancement will aid this. To help encourage female participation, there need to be visible role models, mentoring and coaching opportunities and well-publicised recruitment adverts.

And once these first steps are taken, they have to be followed through with strategies to retain the skilled and experienced female workforce. They must have the same opportunities as men to progress and advance, and female-friendly initiatives need to become written policies. It is known that there is a significant difference in the time that men are prepared to spend onboard compared to women. Overwhelmingly women say they wish to work offshore for a few years and then move to onshore roles to start a family. Few want the challenge of building a family while at sea.

Steps in the Right Direction

In April of this year, over 350 participants attended the WMU (World Maritime University) Empowering Women in the Maritime Community Conference. At close, a set of conclusions based on the development and implementation of gender-related policies was drafted. These included enforcing gender-responsive policies; promoting role models; establishing mentoring programmes; ensuring equal employment opportunities and pay; and engaging with school children to raise more awareness of the sector.

This year’s International Women’s Day in March also saw an important step forwards revealed by the UK government. The Department for Transport has given the 1851 Trust – an educational charity – £100,000 to fund ten roadshows to attract more women to maritime careers.

These are bold initiatives and great steps forward for an industry that is lagging. Change is occurring – despite progress being frustratingly slow. There are a vast number of female-centric initiatives being put into place in recent years, but these will all take time and patience before we start seeing any real change in the maritime workforce.

A Facilitator Definition

Facilitation styles vary from industry to industry, but generally, there are three different ones: delegating, exploratory, and directive. When the facilitator assigns attendees functions, roles, or tasks, that is the delegating style. A facilitator who asks questions about ideas and experience is using the exploratory style. Finally, one who gives instructions and information is directive. The best facilitators use a combination of the three approaches.

The word facilitation comes from ‘facile’ in Latin, which means ‘to make easy’. If we were to go by that definition, a facilitator works to make things easy for other people. Of course, this is a broad definition that would cover a host of other professions as well, including mediation and training. Defining this profession clearly can help create realistic expectations on the part of the client, the facilitator, and the group or organization he or she serves.

What Do Facilitators Do?

Facilitators help organizations or other groups of people understand, plan for, and achieve common goals. In the process, the facilitator doesn’t take a particular position; they remain neutral. Some facilitator tools can assist the organization or group in reaching an agreement on issues that have emerged during a meeting or that already existed.

Types of Facilitators

Business facilitators normally work for companies, but they may also assist other communities or groups. They do not enforce or even state an opinion on the subject of facilitation; their role is to make it easier for the group to make its own decision or find an answer. As conflicts between different management levels can emerge in this process, facilitators have to be very flexible. Facilitators also take measures to empower the groups they work with, increasing their degree of self-determination and autonomy so they are able to represent their interests responsibly.

Normally, facilitators are not experts in the company’s field of activity. For example, if your company works in the automotive industry, you shouldn’t expect the facilitator to possess specific knowledge in this field. Rather, he or she will draw on participants’ existing knowledge in the interaction and, if needed, facilitate access to training if it emerges that knowledge in a certain area is insufficient.  

Facilitators can be appointed to help individuals in small and medium-sized groups solve specific tasks or work through a given problem.

Human Factors

No company can do without meetings. Ideally, these are an effective way to improve team dynamics, exchange information, brainstorm, and reach an agreement on important issues. Unfortunately, it’s all too often the case that executive and staff meetings fail to be productive. Facilitators help avoid this by using a variety of techniques to achieve optimal outcomes depending on the type of meeting. 

Executive and board meetings benefit most from facilitators with experience in design and strategic planning to stimulate discussion and creativity. Meetings are structured so that groups remain focused on strategic factors, in particular, tendencies that could disrupt their sector or industry. With facilitation, clients find relevant and innovative solutions to address these tendencies.

Management meetings benefit from the facilitator’s team management and corporate experience to enhance team interaction. Team members can attain higher levels of productivity and engagement during meetings as a result.

Advantages of an External Facilitator

If your company doesn’t have any staff trained to work as strategic planning facilitators or you’ve never created an official plan for a meeting, you may find an external facilitator quite useful. He or she will bring a new, fresh perspective that participants in a meeting may not have, being too focused on the results. What is more, the staff involved in the planning process will find they can be honest and open with an external participant without fear of conflict with management or coworkers.  

If your company is facing a series of issues and finding it difficult to arrive at an efficient strategy, an external facilitator can help you set appropriate targets and goals. Facilitators have one single responsibility – to offer you guidance in the planning process – and this process will have their full and undivided attention. Your employees have other duties and may not be as invested in this process as an outside consultant.

The Skills of a Good Facilitator

A good facilitator has a variety of different skills and isn’t easy to find. Basic skills include timekeeping, keeping a clear record of meetings, and following the agenda as agreed. More advanced skills are related to extensive knowledge of group dynamics, the ability to build conversation, the ability to paraphrase, to balance participation, and to empower reserved group members. A good facilitator augments group creativity because they have the skills to intervene effectively. They are always respectful of all participants and aware of the multiple layers of a human group’s reality.

If consensus or agreement on an issue cannot be reached, the facilitator helps participants in a meeting understand the factors dividing them. Successful facilitators also possess excellent problem-solving skills. They can enable group decision-making and structure plans and agendas to achieve optimal outcomes.

The Economic and Cultural Value of Facilitators

Facilitators are highly valuable where issues are controversial or complicated, where there are diverse perspectives and interests, or where a high degree of consensus, creativity, and collaboration are needed.

Engaging a professional facilitator is not faster or more cost-effective in the short term, particularly compared to the traditional approach of making and cascading policies, decisions, and plans from the top down. 

If these policies, decisions, and plans aren’t achieving the desired results, it may be because the employees crucial to their success haven’t played an optimal role in the process. Down the line, an investment in a more effective, efficient, and inclusive process can save your company a lot of money.

Facilitators bring the additional advantage of familiarity with different work environments and cultures. Cultural differences can emerge as an obstacle in strategic planning and facilitators have the experience needed to help participants understand these and reach a consensus despite them.

What Should You Look for in a Facilitator?

The International Association of Facilitators (IAF) has six guiding principles for those looking for a specialist facilitator. According to IAF, competent facilitators plan appropriate group processes, build and maintain an inclusive environment, create collaborative client relationships, develop and sustain professional knowledge, guide the group to suitable and optimal outcomes, and model professional and positive attitudes. Evidence of these skills can be found in a facilitator’s resume, case studies, testimonials, or references from previous clients.

You may be looking for outside support to develop in-house competence and capacity to establish and facilitate processes to achieve long-term goals. In other words, you may need facilitation services for a longer period of time. If this is the case, look for experience in facilitator coaching or facilitation training as well.

Finally, take into account the magnitude of your tasks in terms of space, time, and the number of people involved. You might find it best to engage an organization with a broad network of associates in case your facilitator needs assistance from a coworker or a facilitator team. A participatory, multifaceted approach is something your company can only benefit from.

Facilitators in commercial industries may place a greater focus on promoting creativity and reconciling individual differences, while those in state or government organizations will fulfill the role of organizers and integrators. The most effective facilitators utilize a combination of these approaches.   


Hi, Jason here again. Sylvia does a great job of covering some of the main concepts of facilitation. There are soft skills and techniques that would make a good facilitator across industry sectors for example:

  • A great facilitator will focus on shared ideas raised during the workshop, not on historic mistakes or achievements.
  • There’s an art to creating an atmosphere of energy and a meritocracy of input.
  • Finding that balance of leading the meeting, but also creating a leaderless zone at the same time.
  • Careful recording and the drawing out of action points is also an art. Anyone can find challenges and pitfalls, not everyone can crowdsource a robust plan and record it in a report.

Here’s a quick video where common best and worst practices are highlighted:

The lively debate:

From time to time, the topic of a facilitators competency comes into question. Some would argue that the best facilitators are able to get everyone together in harmony and that the expertise from the participants is the priority. It’s possible to envisage someone with great people skills, but without industry experience creating a great workshop. Imagine Tony Robbins facilitating a meeting at the sales department of a hardware distribution company. That would work, wouldn’t it? Would it matter if Tony has ever sold the same widgets as the team? Probably not.

An external facilitator has an advantage because they can treat people equally without fear of political consequence.

For industrial workshops, such as the ones in the oil and gas industry that Relentless Pursuit of Perfection host, we argue that a general facilitator won’t suffice. Can you imagine the same scenario with Tony facilitating a plan of action for a hazard and operability (HAZOP) study? What about Tony working with a bomb disposal team, as Phil Smith and the team at Critical Team Performance do? On balance, most would prefer to work with those that have had skin in the game and are seen as professional industry equals.

There are a few reasons that spring to mind for this rationale:

  1. Unlike the average office-based job, an oil rig is stressful for the mind and body – and dangerous, potentially deadly. Camaraderie and group focus is experienced by people who have taken the same risks and had the same stories to tell.
  2. A facilitator that holds workshops for different companies in the same industry, all over the world will often know answers to challenges that come up. They can absorb combined knowledge from all of the teams that they interact with.
  3. The notes recorded during the workshop and the post-workshop reports contain degree level, and often postgraduate-level science, knowledge and industry jargon. Have you ever tried to take notes about, and then write about something you know nothing about? What if lives depended on it all being accurate?

What do you think? What has been missed? Does an external facilitator need extensive personal experience in the same industry vertical? Perhaps you prefer an in-house person to lake lead on a workshop? Please comment below.

The post US Shale Update Through June 2019 appeared first on Drillers.


These interactive presentations contain the latest oil & gas production data from 114,539 horizontal wells in 12 US states, through June 2019. Cumulative oil and gas production from these wells reached 11.7 billion bbl and 133.7 Tcf of natural gas. West Virginia is deselected in most dashboards, as it has a greater reporting lag. Oklahoma is for now only available in our subscription services.

Oil production from horizontal wells in these states increased slightly in June, to around 7 million bo/d (after upcoming revisions). That would represent a growth of 100 thousand bo/d in the first 6 months, far lower than the ~670 thousand bo/d increase in the same period last year, but still positive.

As is visualized in the chart above, total oil production in June can be divided into 3 roughly equal parts: the contribution from wells that began production in the first 6 months since year (dark blue), the ones that started last year (light blue), and all the wells that came online before 2018 (all other colors).

Natural gas production also set a new record (switch “Product” to gas), at 64 Bcf/d.

In the “Well quality” tab, you can easily see how well productivity has changed in the major tight oil basins. Results have steadily improved since 2008, but markedly slower after 2017. Normalized for lateral length (which is possible in our advanced analytics service), and averaged for all the oil wells in these basins, we see no clear improvement since 2016.

EOG is by far the largest operator of tight oil wells (see “Top operators”), producing almost double the numbers 2 to 5. However, its production dropped by almost 8% in June, from which it somewhat recovered in July (based on preliminary data, not visible here).

This “Ultimate recovery” overview shows the relationship between production rates and cumulative production over time. The oil basins are preselected and the wells are grouped by the year in which production started.

The 2nd tab (“Cumulative production ranking”), ranks all counties by cumulative oil production. McKenzie County is shown here in the top spot. Since 2005 more than 1 billion barrels of oil have been produced in this county from horizontal wells, and production is still above half a million bo/d. Lea, Midland, Reeves and Weld are also close to this production rate.

In the following overview (taken from our ShaleProfile Analytics service (Professional)) you can see how well productivity has evolved in each of these 5 counties.

Well productivity in the top-5 oil-producing counties

The chart on the top-right shows the average cumulative oil production in the first year on production, by production start date, for each of these counties. It clearly shows that based on this metric, McKenzie is still the most productive area. If you normalize for lateral length in this dashboard, Lea is clearly outperforming the other areas. That probably explains why you can now find the most rigs drilling horizontal wells in Lea County, based on the latest rig count (65, vs. 53 in Reeves and just 18 in McKenzie).

The charts below it reveal that McKenzie also has the longest laterals, while in Midland most proppant is used.

Early next week we will have a new post on North Dakota. Production data through July, in which another production record was set, is already available in our subscription services since last week.

Production data is subject to revisions. For these presentations, I used data gathered from the sources listed below.

  • FracFocus.org
  • Arkansas Oil & Gas Commission
  • Colorado Oil & Gas Conservation Commission
  • Louisiana Department of Natural Resources. Similar to Texas, lease/unit production is allocated over wells in order to estimate their individual production histories.
  • Montana Board of Oil and Gas
  • New Mexico Oil Conservation Commission
  • North Dakota Department of Natural Resources
  • Ohio Department of Natural Resources
  • Pennsylvania Department of Environmental Protection
  • Texas Railroad Commission. Individual well production is estimated through the allocation of lease production data over the wells in a lease, and from pending lease production data.
  • Utah Division of Oil, Gas and Mining
  • Automated Geographic Reference Center of Utah.
  • West Virginia Department of Environmental Protection
  • West Virginia Geological & Economic Survey
  • Wyoming Oil & Gas Conservation Commission


The above presentations have many interactive features:

  • You can click through the blocks on the top to see the slides.
  • Each slide has filters that can be set, e.g. to select individual or groups of operators. You can first click “all” to deselect all items. You have to click the “apply” button at the bottom to enforce the changes. After that, click anywhere on the presentation.
  • Tooltips are shown by just hovering the mouse over parts of the presentation.
  • You can move the map around, and zoom in/out.
  • By clicking on the legend you can highlight selected items.
  • Note that filters have to be set for each tab separately.
  • The operator who currently owns the well is designated by “operator (current)”. The operator who operated a well in a past month is designated by “operator (actual)”. This distinction is useful when the ownership of a well changed over time.
  • If you have any questions on how to use the interactivity, or how to analyze specific questions, please don’t hesitate to ask.
