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.
ResFrac is used by 35+ leading E&P companies
Operators of all sizes across the globe choose ResFrac for modeling. We are being used in every major shale play across North and South America.

Recorded ARMA HFC 2023 Series Presentation– Optimization of Perforation Phasing for Improving Uniformity of Proppant Distribution Between Clusters
This ARMA Hydraulic Fracturing Community (HFC) presentation summarizes the work on proppant transport in horizontal perforated wellbores. Specifically, it discusses the model for proppant distribution between perforations depending on their orientation and location within the stage, optimal configurations are proposed, and performance is evaluated.

ResFrac at the Breckenridge Imperial Challenge
It’s that time of year again for our ResFrac team to embark upon the Imperial Challenge in Breckenridge, CO! As with last year, Egor, Dirk (ResFrac investor), and Garrett tackled the challenge this year. The Imperial Challenge is an annual triathlon where racers bike or run from the town of Breckenridge 6 miles and 850 feet up to the base of the Breckenridge ski resort, then skin (ski uphill) 3000 ft to the peak of the resort at 12,998 ft, then… ski off the other side.

Technical barriers for deep closed-loop geothermal
This is the most exciting time in my lifetime for geothermal. There are many, many innovative things happening. To name a few – promising new approaches to Enhanced Geothermal Systems, geothermal projects in sedimentary and lower enthalpy formations, new approaches for geothermal exploration, lithium extraction from produced brines, geothermal energy storage, integrations with CO2 storage and capture, and new technologies for producing energy from hot water that is coproduced with oil and gas. However, this post is about a concept about which I remain skeptical – deep closed-loop heat exchangers (McClure, 2021). These designs are sometimes called ‘Advanced Geothermal Systems,’ AGS (Malek et al., 2022).
