Applications
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.

Production impact of horizontal fractures
At the 2025 SPE International Hydraulic Fracturing Technology Conference, we (Dontsov, Zoback, McClure, and Fowler) presented “Hydraulic Fracture Propagation Along Bedding Planes Might Be More Prevalent Than We Think” (SPE-226637). The paper reviewed case studies with evidence of horizontal or bedding plane fractures from microseismic, fiber optics, core observations, and casing deformation.
Testing the new Kryvenko model for proppant washout
What controls proppant placement during hydraulic fracturing? As described in Chapter 8 from McClure et al. (2025), ResFrac incorporates a variety of physical processes – viscous drag, gravitational settling, hindered settling, clustered settling, bed slumping, and more. In addition, ResFrac accounts for the complex physics associated with proppant flowing out of the wellbore (Dontsov, 2023; Ponners et al., 2025).
Horizontal hydraulic fractures in ResFrac
Horizontal hydraulic fracture propagation is believed to be widespread in shale plays where the frac gradient approaches the overburden – such as the Vaca Muerta, Utica, and Montney. However, horizontal propagation is nearly always ignored in hydraulic fracture modeling. In ResFrac, we are obsessed with ‘getting the physics right’, and so naturally, we extended our simulator to handle horizontal fracturing. The first version of this new capability was released earlier this year. We are eager to start collecting feedback from users, which will help us to fine tune the algorithm and workflow.
