More about the apps


Maximize uniformity of fluid and proppant outflow from the wellbore during each stage.


Analyze interference tests to estimate fracture conductivity and the degree of production interference.


Use modern best-practices to interpret Diagnostic Fracture Injection Tests to estimate stress, permeability, and pore pressure.

QEP used ResFrac to help evolve their designs towards higher cluster density and longer stage length, leading to increased production and lowered cost.
“We tested 60+ different variations on fluid and proppant loadings, cluster and stage spacing, and well counts and landing zone configurations … and produced an economically optimized recommendation.” Engineer, Permian Basin

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. The results from McClure et al. (2016) demonstrated that common practices for stress estimation often underestimate the true magnitude of the minimum principal stress, a finding that has been subsequently been confirmed by direct in-situ measurements and laboratory experiments, as well as in the field measurements reviewed by McClure et al. (2016).
