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.

Interesting Papers from the 2026 SPE Hydraulic Fracturing Technology Conference (HFTC)

The 2026 HFTC included 50+ technical paper presentations, a special session highlighting papers from the American Rock Mechanics Association (ARMA), and a dynamic opening session featuring the Secretary of Energy, Chris Wright, and a diverse panel discussion with representatives from Chevron, Exxon, US Department of Energy, and Colorado School of Mines.

Production impact of horizontal fractures

At the 2025 SPE International Hydraulic Fracturing Technology Conference, we (Dontsov, Zoback, McClure, and Fowler) presented “Hydraulic Fracture Propagation Along Bedding Planes Might Be More Prevalent Than We Think” (SPE-226637). The paper reviewed case studies with evidence of horizontal or bedding plane fractures from microseismic, fiber optics, core observations, and casing deformation.

Testing the new Kryvenko model for proppant washout

What controls proppant placement during hydraulic fracturing? As described in Chapter 8 from McClure et al. (2025), ResFrac incorporates a variety of physical processes – viscous drag, gravitational settling, hindered settling, clustered settling, bed slumping, and more. In addition, ResFrac accounts for the complex physics associated with proppant flowing out of the wellbore (Dontsov, 2023; Ponners et al., 2025).
