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.

Interesting Papers from the 2026 SPE Hydraulic Fracturing Technology Conference (HFTC)
The 2026 HFTC included 50+ technical paper presentations, a special session highlighting papers from the American Rock Mechanics Association (ARMA), and a dynamic opening session featuring the Secretary of Energy, Chris Wright, and a diverse panel discussion with representatives from Chevron, Exxon, US Department of Energy, and Colorado School of Mines.
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).
