Before joining ResFrac, Danial served as a reservoir engineering specialist at ShearFrac, where he spearheaded the development of a fully automated application for real-time post-fracture pressure decay analysis. He holds a PhD in petroleum engineering from the University of Calgary and a Bachelor’s degree in reservoir engineering from the Petroleum University of Technology in Iran. During his doctoral research, Danial focused on advancing the design and analysis of the diagnostic fracture injection test-flowback analysis (DFIT-FBA) method. During this time, he collaborated with leading oil and gas companies such as Ovintiv, Birchcliff Energy, ConocoPhillips, Origin Energy, TotalEnergies, and Encino Energy to implement the DFIT-FBA technique.

In his free time, Danial enjoys hiking, playing squash, volleyball, and avidly following mixed martial arts, football, and soccer.

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.
