Downhole Materials Selection

In oil and gas production, the main corrosive constituent is CO2 and the corrosion rate increases initially with increase in its partial pressure and temperature and then decreases beyond a temperature due to film formation. The rate is also affected by characteristic of produced water, flow rate, oil/water ratio, oxygen, etc.

Course Objective

This short course will give an insight into how Material selection shall be optimised, considering investment and operational/maintenance costs, such that overall costs are minimised while providing acceptable safety and reliability. As a minimum, the following should be considered:

• Corrosivity, considering specified operating conditions, including start-up and shut-down conditions.

• Design life and system availability requirements.

• Failure probabilities, failure modes and failure consequences for human health, environment, safety and material assets.

• Inspection and corrosion monitoring possibilities

Audience

Invaluable for production, operations, and integrity professionals involved in implementing & managing well integrity and seeking to improve performance. It is also essential for those who need to develop and implement such systems, or who require an understanding of well integrity management.

This micro VILT will also provide a fresh approach for senior professionals and managers. Designed for professionals in the oil and gas industry who are involved in the design, construction and operation of wells from the following disciplines:

Production maintenance
Production operations
Drilling engineering
Safety engineering
Well intervention
Well integrity engineering
Asset management

Prerequisite

A basic understanding of drilling and completion principles and some industry exposures are desirable for participants before enrolling in this course. However, this course can be adapted to meet the needs of all attendees.
