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.


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.

Automated history matching to fracture geometries as measured by Volume to First Response (VFR): A Tutorial

In this post, I will walk through a simple example of using SWPM to calibrate the fracture geometries of a hypothetical data set leveraging the ResFrac Automated History Matching functionality to expedite the workflow. In a follow-on post, I use the model to demonstrate some intuitions on fracture geometry using the Sensitivity Analysis functionality as well as some nuances of VFR calibration.

Highlights on propagation from preexisting fractures in ResFrac

The purpose of this blog post is to cover recently developed ResFrac capability that allows investigation of the effect of natural fractures on hydraulic fracture propagation. While this option has always been available for the ‘discrete’ propagation algorithm, now it also has become available for the ‘continuous’ algorithm. There are some noticeable changes compared to the previous implementation and they are covered next.

simulation with five wells in a hypothetical formation with two pay zones. In the base simulation, all the wells are landed in the upper pay zone. However, the algorithm is given the option to vary the landing depth of the second and fourth wells. The figures below show the ‘baseline’ simulation.

ResFrac’s Automated Economic Optimization Tool

ResFrac’s automated optimization tool allows you to quickly and easily identify the economically best well spacing and frac design. This blog post steps through a simple demo of our built-in economics engine that is similar to those used by commercial software in the industry. It accounts for details such as working interest, different types of taxes, time-varying operations cost, etc.
