Garrett Fowler is Chief Operating Officer at ResFrac, responsible for overseeing client engagement, professional services, and software licensing.

ResFrac is a software company whose primary product is a fully-coupled hydraulic fracture, reservoir, and geomechanics simulator. Garrett has led modeling studies in every major shale basin, as well as geothermal and conventional projects. Prior to ResFrac, Garrett was a reservoir engineer at OXY and Tachyus, working on CO2 EOR, waterfloods, steamfloods, and cyclic steam injection.

Garrett attended Stanford University, where he graduated with distinction, receiving a Master of Science degree in petroleum engineering and a Bachelor of Science in energy resources engineering. Garrett was awarded a 2022 SPE Regional Completions Optimization and Technology Award, a 2023-2024 SPE Distinguished Lecturer, and authored or co-authored 21 technical papers. He is an Eagle Scout, multiple-time Ironman finisher, and a search and rescue diver.

The influence of well configuration on water loss in Enhanced Geothermal Systems

Recently, ‘water loss’ has been a hot topic of discussion for EGS. Fervo reported that they have been producing only 70% of the fluid volumes that they have been injecting at their Project Red. The FORGE project reported a roughly 10% water loss rate. Because projects will have finite water rights, these results have led to concern that growth of EGS will be limited by excessive water consumption. This is a valid concern, and water availability is a legitimate factor in site-selection and project engineering. However, I believe that the problem has been overstated.

2026 ResFrac Annual Symposium Recap

On June 25, 2026, we got the ResFrac community together both in-person at the ExxonMobil campus in Spring, Texas, and virtually around the globe for our Annual Symposium. With our community growing as fast as it is, the energy in the room was absolutely buzzing. We had a jam-packed day of operator case studies, deep-dive technical sessions, and some incredible geomechanical insights from industry legends.

FracTest – An Online Tool for DFIT Interpretation

This week, we are releasing FracTest, a web-based application for interpretation of diagnostic fracture injection tests (DFITs). FracTest is available at resapps.resfrac.com, alongside our other two ResApps, StageOpt and IntTest. DFITs are small-volume fracture injection tests used to estimate stress, pore pressure, and permeability. These quantities form the foundation of the fracture and reservoir engineering work that we do in ResFrac, and so we view DFIT interpretation as one of the most important parts of our workflow.
