Rohan Irvin

Australasia Technical Team Lead

Rohan Irvin is a reservoir engineer with 17 years of oil and gas experience at Oxy, Woodside, EnergyCapture, and others. He believes energy abundance is the foundation of a prosperous world. As a member of the ResFrac team, he can have the greatest impact on energy abundance by helping operators optimize their developments.

Prior to joining ResFrac, he advised EnergyCapture on the development of their unconventional gas assets in Queensland, Australia. Using ResFrac to evaluate and optimize their completion designs, he was able to significantly improve the economic value of the development. He has worked on most of the major basins in the US as well as West Africa, the Middle East, North West Shelf (Australia), and India. While with Oilex in India, he led the engineering evaluation of the country’s first horizontal, multi-stage frac completion. With Oxy, he led a multi-disciplinary subsurface team during the early evaluation of the Permian Basin’s unconventional potential. Throughout his career, he has been responsible for exploration support, appraisal data acquisition, development planning, and reservoir management of both conventional and unconventional assets.

Rohan received a Bachelor of Engineering degree in oil & gas engineering from the University of Western Australia (receiving the Dr. Mark Skinner Prize for the top final year student) and a Masters of Science in petroleum engineering from the University of Southern California.

Rohan is a husband and father of two, Queen’s Scout (Eagle Scout), multiple Ironman finisher, and surfer. He once watched the sun rise on New Year’s Day from the summit of Mount Kilimanjaro.

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.
