About us
ResFrac is used by 35+ leading E&P companies
Built on science-based decision-making
Operators are engaged in a process of continuous improvement – with a relentless focus on maximizing free cash flow. We apply cutting-edge technology and a rigorous workflow to accelerate the improvement cycle.
A highly regarded colleague once said: “We reserve the right to get smarter.” Our commitment is to embody this spirit to the best of our ability – whether that means continually evolving our software and implementing the latest findings from academia and literature, or approaching a collaboration with scientific curiosity and excitement.
Recent projects such as HFTS1, HFTS2, the ConocoPhillips core-through in the Eagle Ford, and MSEEL have transformed the industry’s understanding of shale fracturing, challenging conventional wisdom and unlocking new opportunities. Downhole data collection has never been better. Fiber in injection and offset wells, downhole imaging, sealed pressure monitoring, pressure observation wells, among many others, are giving us an unprecedented look at subsurface processes in shale. By working with a diversity of companies across all major shale plays, we’ve built a broad perspective and understand the commonalities and differences. This deep understanding – rooted in the groundbreaking work happening in the industry – enables subsurface engineering to be performed more accurately and drive more value than ever before.
Collaboration
We are fortunate to work with some of the most outstanding people in our industry, and with some of the most innovative companies. We work together to advance the science, while keeping the focus on solving practical problems that impact the bottom line.
Continuous improvement
Everyone at ResFrac brings a growth mindset to their work, helping operators and the broader community solve problems and improve operational efficiencies. We apply that growth mindset to ourselves, our company, our clients, and the profession as a whole.
Making a tangible impact
We believe in the dignity of an honest, hard day’s work. Every day, we strive to make a positive impact on our little corner of the world.

Introducing StageOpt – State-of-the-Art Calculations for Optimizing Perforation Design
ResFrac Corporation is built around the ResFracPro simulator, which is the only commercial simulator that fully integrates genuine hydraulic fracture modeling and reservoir simulation. Now, we are broadening to build a complementary suite of apps – which we are called ‘ResApps.’

Recent Recorded Talks on EGS and DFIT
Below are links to watch two recently recorded talks. The first was a presentation with ThinkGeoEnergy discussing the impressive results from Fervo Energy’s recent Project Red pilot. The second was a presentation with whitson summarizing the URTeC-2019-123 compliance method procedure for interpreting DFITs. If you are interested in either topic, please check them out!

Practical guidelines for DFIT interpretation using the ‘compliance method’ procedure from URTeC-2019-123
This blog post provides practical tips for interpreting Diagnostic Fracture Injection Tests (DFITs) using the ‘compliance method’ procedure initially developed by McClure et al. (2016) and refined in the paper URTeC-2019-123, which summarized results from a joint industry study performed with a consortium of operators.
