Introducing StageOpt – State-of-the-Art Calculations for Optimizing Perforation Design
ResFrac Corporation is built around the ResFracPro simulator, which is the only commercial simulator that fully integrates genuine hydraulic fracture modeling and reservoir simulation. Now, we are broadening to build a complementary suite of apps – which we are called ‘ResApps.’

Recent Recorded Talks on EGS and DFIT
Below are links to watch two recently recorded talks. The first was a presentation with ThinkGeoEnergy discussing the impressive results from Fervo Energy’s recent Project Red pilot. The second was a presentation with whitson summarizing the URTeC-2019-123 compliance method procedure for interpreting DFITs. If you are interested in either topic, please check them out!

Practical guidelines for DFIT interpretation using the ‘compliance method’ procedure from URTeC-2019-123
This blog post provides practical tips for interpreting Diagnostic Fracture Injection Tests (DFITs) using the ‘compliance method’ procedure initially developed by McClure et al. (2016) and refined in the paper URTeC-2019-123, which summarized results from a joint industry study performed with a consortium of operators.
