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.

Automatic Report Generation in ResFracPro

This month’s release has a feature that I am particularly excited about – automatic report generation. The reports are generated automatically when a simulation finishes. Also, reports can be generated on-demand for simulations that have already been completed. The reports are highly customizable, allowing the user to generate different line plots, 3D visualizations, preview plots, and tabular data. The user can provide a template PPT, so that the report is made with their preferred PPT style.

Introducing ResFrac’s New Multisector Capability

This month’s ResFrac release has a ton of new capabilities. The most important is called ‘multisector’ – the ability to split different sections of the well across different computers. This capability provides a computationally efficient and practical way to run larger models and handle complex scenarios. Hats off to Danial Zeinabady and Michael Nole, who have been the main developers on this project. Beyond them, it’s been a big team effort, pulling in folks from cloud, simulator, and user-success. First, let’s review – what is sector modeling? Why do we need a ‘multi’ version of it?

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.
