Tools to facilitate key engineering and geoscience workflows

Cutting-edge capabilities in practical, easy-to-use apps


Predict the effect of perforation design on fluid and proppant transport from the wellbore.


[Coming Soon] Apply the CPG and DQI procedures to assess fracture conductivity and degree of production impact.


[Coming Soon] Accurately estimate stress, permeability, and pore pressure from DFITs.

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

Hydraulic fracture models shouldn't be a black box. We provide a detailed technical writeup so you know what the simulator is doing and why.

Take a Training Course

We’re committed to supporting knowledge sharing in the oil and gas industry. That’s why our course is available online for anyone who wants to take it. Explore modules on coupled hydraulic fracture, geomechanics, and reservoir simulation using the ResFrac simulator.



ResApps are a suite of tools designed to facilitate key engineering and geoscience workflows.

Yes, you can! ResApps are licensed separately from the ResFrac simulator.

No, the apps are entirely web-based.

Submitted data are stored in an encrypted database hosted on Microsoft Azure. Data are keyed by user, so users are only able to access their own data. All data transmissions are handled using industry-standard encrypted protocols. 

Licenses are annual subscriptions for individual-users. For more information on ResApps site login and app signup, see the tutorial here.

Horizontal hydraulic fractures in shales: are they real?

In ResFrac, we are always challenging ourselves—what should we be doing better? What new capabilities should we add to the simulator? One of our newest projects is adding horizontal fracture propagation. Under most conditions, hydraulic fractures form vertically, not laterally. However, in specific circumstances, horizontal fractures develop. Sometimes, they form in addition to vertical fractures, and sometimes, they form exclusively without any vertical fractures. Horizontal fracture propagation has not conventionally been included in commercial hydraulic fracturing simulators, but we think this is a capability well-worth developing.

Previewing the Seven(!) ResFrac Papers to be Presented at the Unconventional Resources Technology Conference

Next week, ResFrac will be coauthoring seven papers at the Unconventional Resources Technology Conference (URTeC). These papers include: operator case studies in the Haynesville, Marcellus, and Bakken, a study quantifying the effect of proppant uniformity on production and economics, a new procedure generalizing the Devon Quantification of Interference (DQI) method, and an excellent paper by a University of Texas PhD student on proppant flowback.
