Pat T.W. Chisholm
Profile
Diversely experienced petroleum engineer, focusing on optimizing results. Extensive on-location fracturing experience, with proven problem solving skills. Unique ability to diagnose/identify problems and implement effective, often innovative solutions. Expertise in well evaluation and stimulation. Team player with highly effective communication skills and ability to instruct others.
Major Examples of Innovation: Devised “Fluid Efficiency Testing” (FET) to refine frac programs on location, which is now standard procedure throughout the industry by Halliburton and service companies worldwide. Patent on “Constant Internal Phase” concept to permit pumping higher sand concentrations on foam fracs. This concept is the standard for all foam fracturing today. These innovations have contributed greatly to maximizing production and increasing the return from stimulation investments.
Skills and Areas of Expertise
- Fractured many deep, hot, high pressure wells. Worked extensively on early massive fracs, REFRACS, depleted reservoirs, high fluid loss, fluid efficiency, optimization, and orientation. Worked on Acid fracs and stimulation in Austin Chalk and Edwards Limestone.
- Developed FET to optimize frac design on location which reduced costs, prevented screen-outs, enhanced job performance, and improved results.
- Invented and implemented the “Constant-Internal Phase Foam Frac Theory,” which enabled the industry to pump high proppant concentrations of foam fracs for the first time.
- Supervised stimulation. Established Quality Control and direction in planning, design, procedures, materials, training, equipment, execution, and safety. Worked with field operators and research engineers modernizing frac equipment for high sand concentrations, high pressures, and performance. Was Field Advisor to Research for development of state of art ADC blenders, ARC equipment, pumps, and software.
- Evaluated DST, production and pressure data to design needed stimulation. Supervised treatments. Reviewed treatment logs for indications of problems and made corrections which prevented job failures.
- Taught in-house and customer schools on hydraulics, procedures, safety, and formation evaluation.
- Planned, supervised, and evaluated OPEN HOLE Drill Stem Tests (DSTs) and offshore cased-hole tests. Gave presentations on DSTs tools, procedures, chart interpretation, and calculation.
- Planned and supervised primary and squeeze cementing, acidizing, sand control, blow-outs, lost circulation, grouting, industrial cleaning, hydro-jetting, training, job planning.

John Lee is Professor of Petroleum Engineering and holder of the Cullen Distinguished University Chair at The University of Houston. He served as an Academic Engineering Fellow with the U.S. Securities & Exchange Commission (SEC) in Washington during 2007-8, and was a principal architect of the new SEC rules for reporting oil and gas reserves.
John holds BS, MS and PhD degrees in chemical engineering from the Georgia Institute of Technology.
He worked for ExxonMobil, specializing in integrated reservoir studies, prior to joining the Texas A&M faculty. He later was Regents Professor of Petroleum Engineering at Texas A&M. While at A&M, he also served as a consultant with S.A. Holditch & Associates, where he specialized in reservoir engineering aspects of unconventional gas resources. He joined the University of Houston faculty in September 2011.
John is the author of three textbooks published by SPE and has received numerous awards from SPE, including the Lucas Medal, the DeGolyer Distinguished Service Medal and Honorary Membership. He is a member of the U.S. National Academy of Engineering and the Russian Academy of Natural Sciences.
