ResFrac Corporation makes hydraulic fracturing and reservoir simulation software for the exploration and production industry. 

ResFrac's flagship product is a fully integrated hydraulic fracturing and reservoir simulator that can model the full well life cycle from treatment through production. We offer licenses for the use of the software, and also provide professional services based on our technology and expertise. 


Additionally, we address relevant questions in fracture mechanics and reservoir engineering through our Industry Studies, such as our Diagnostic Fracture Injection Test (DFIT) Industry Study.


Mark McClure

Mark McClure founded ResFrac in 2015 to help operators maximize value through 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 and earned a PhD in Energy Resources Engineering at Stanford University. Mark's academic research is on hydraulic fracturing, proppant transport, diagnostic fracture injection tests, induced seismicity simulation and statistics, and Enhanced Geothermal Systems.
