Mark McClure established ResFrac in 2015 to help operators maximize value through the application of advanced geomechanics and reservoir simulation.

Before founding ResFrac, Mark was an assistant professor at the University of Texas at Austin in the Department of Petroleum and Geosystems Engineering. After earning a Bachelor of Science in chemical engineering and a Master of Science in petroleum engineering from Stanford University, Mark earned a PhD in energy resources engineering at Stanford.

Mark has earned multiple awards, including the Hank Ramey Award from Stanford University, Best Paper in Geophysics, an outstanding paper award at URTeC, Hart Energy 40 Under 40, SPE Regional Awards for Completions Optimization and for Young Member Service, and SPE’s TWA Energy Influencers award. On four occasions, he has received recognition from journals as an outstanding reviewer.

In his free time, Mark enjoys hiking, playing with his dog, watching sports, and traveling.

The influence of well configuration on water loss in Enhanced Geothermal Systems

Recently, ‘water loss’ has been a hot topic of discussion for EGS. Fervo reported that they have been producing only 70% of the fluid volumes that they have been injecting at their Project Red. The FORGE project reported a roughly 10% water loss rate. Because projects will have finite water rights, these results have led to concern that growth of EGS will be limited by excessive water consumption. This is a valid concern, and water availability is a legitimate factor in site-selection and project engineering. However, I believe that the problem has been overstated.

2026 ResFrac Annual Symposium Recap

On June 25, 2026, we got the ResFrac community together both in-person at the ExxonMobil campus in Spring, Texas, and virtually around the globe for our Annual Symposium. With our community growing as fast as it is, the energy in the room was absolutely buzzing. We had a jam-packed day of operator case studies, deep-dive technical sessions, and some incredible geomechanical insights from industry legends.

FracTest – An Online Tool for DFIT Interpretation

This week, we are releasing FracTest, a web-based application for interpretation of diagnostic fracture injection tests (DFITs). FracTest is available at resapps.resfrac.com, alongside our other two ResApps, StageOpt and IntTest. DFITs are small-volume fracture injection tests used to estimate stress, pore pressure, and permeability. These quantities form the foundation of the fracture and reservoir engineering work that we do in ResFrac, and so we view DFIT interpretation as one of the most important parts of our workflow.
