​​Reservoir and Drilling Fluids Expert

ACME Fluids Training – The home of in-depth Reservoir Drilling Fluids Training

David is the owner of ACME Fluids Training. ACME’s mission is to the teach the processes behind the development of reservoir drill-in fluids (RDF’s) that are optimized for individual wells.

Classes are conducted in small groups-never more than 15 attendees, and usually with a maximum of 10. This is to emphasize the interaction between students and instructors as part of the learning process.

David is also available as an independent RDF consultant for any related project. He can deliver solutions to fit the needs of each individual client. He can work on-site, remotely, or in your office, and can travel anywhere in the US or Internationally.

Dave Messler ACME Fluids training

Bio:

Mr. Messler brings over 38 years of completions experience as a Field Engineer, Project Engineer, Training Instructor, and Technical Service Manager into the class room. For the last fifteen years he has specialized in fluids applications for open-hole completions, in the GoM, Brasil, Malaysia, and Australia while working in the M-I SWACO division of Schlumberger.

In various field, technical, and training positions, he has designed, and implemented completion and reservoir drilling fluids for a variety of sand face completion methods; predominantly: open-hole gravel packs, slotted liners, and standalone screens.

As a Trainer and Consultant his career arc has taken him to most major petroleum basins including: The west coast of the USA, the Gulf of Mexico, the North Sea, Latin America, Australia, and finally to Asia. In mid- 2015 he retired from Schlumberger’s M-I SWACO unit in Malaysia. As a Trainer, attached to M-I SWACO’s Houston office, he was the Global Trainer for the WP product line focusing on Completion Fluids, Reservoir Drilling Fluids, and IWA Displacement and Workshop classes.

Core Expertise:

  • Reservoir drilling fluids and breakers-testing and design.

  • Trouble shooting RDF candidate fluid failures.

  • Formation damage minimization from reservoir drilling fluids.

  • Non-damaging Fluid Loss Pills.

  • Completion brines.

  • Filtration.

  • Well bore cleanups and displacements mechanical and chemical.

  • Open-hole completion logistics and pit management.
