What ResFrac does
ResFrac Corporation is a private engineering software company founded in 2018 and headquartered in Palo Alto, California, with additional offices in Denver and Houston. The company develops ResFracPro, which the company describes as the industry's only fully integrated reservoir simulation and hydraulic fracturing platform. ResFracPro solves multiphase flow, 3D fracture mechanics, proppant transport, poroelastic stresses, wellbore dynamics, and thermal effects in a single continuous simulation, using true fracture mechanics meshing rather than the high-permeability-slab approximation common in conventional reservoir simulators. Simulations run on Microsoft Azure cloud infrastructure while engineers interact through a locally installed Windows client.
The company serves oil and gas E&P operators (independents, supermajors, and national oil companies) across every major North American shale play, as well as Enhanced Geothermal Systems developers such as Fervo Energy. Named customers include Pioneer Natural Resources, Devon Energy, Chevron, and Fervo Energy. Beyond the core simulator, ResFrac monetizes through ResApps (a suite of web-based tools including StageOpt, IntTest, and FracTest licensed as standalone subscriptions), turnkey consulting services, and four-day training courses priced at $2,500. The company has co-authored 81+ technical papers and reports 2.4M+ simulation hours per year across 60+ customers.
In April 2026, Banneker Partners made a platform investment acquiring a majority stake, with prior seed investor Altira Group exiting. The company's leadership includes Stanford PhD co-founders Mark McClure (CEO), Charles A. Kang (CTO), and Garrett Fowler (COO), supported by Chief Scientist Egor Dontsov. The fully remote team spans 11-50 employees across US and Canadian time zones, with technical and consulting staff organized around reservoir and completions, Australasia operations, and software/DevOps functions.

ResFrac product offering
Product offeringCore offering
ResFrac develops and licenses ResFracPro, the industry's only fully coupled hydraulic fracturing and reservoir simulator that solves multiphase flow, 3D fracture mechanics, proppant transport, poroelastic stresses, wellbore dynamics, and thermal effects in a single continuous physics-based simulation. The platform is complemented by ResApps (web-based tools: StageOpt, IntTest, FracTest), turnkey consulting services, and training programs targeted at oil, gas, and geothermal operators worldwide.
Product overview
ResFrac offers a single-platform architecture centered on ResFracPro, the industry's only fully coupled hydraulic fracturing and reservoir simulator. The platform integrates a true hydraulic fracturing simulator with a reservoir simulator (including geomechanics), solving all governing physics simultaneously at every timestep. Supporting the core platform is ResApps, a suite of three standalone web-based tools (StageOpt, IntTest, FracTest) for specific engineering workflows. The company also provides professional consulting services and training programs (both online and in-person). EGS Solutions extend the platform for geothermal applications. ResChat provides AI-powered assistance for navigating resources.

ResFrac competitors and assessment
Company assessmentEmerging players
- ANSYS: ANSYS provides multiphysics simulation platforms (Mechanical, Fluent) used in some upstream energy applications, particularly for fracture mechanics and computational fluid dynamics. While not a direct E&P reservoir simulator competitor, ANSYS overlaps with ResFrac on the underlying numerical methods and serves engineering teams that may consolidate simulation workflows onto broader platforms.
- Golder (now part of WSP): WSP/Golder's FracMan software is a long-standing discrete fracture network (DFN) simulation tool used in unconventional E&P and geothermal applications. FracMan competes with ResFrac for fracture modeling workflows, particularly in DFIT interpretation and parent/child interaction studies where both platforms offer overlapping capabilities.
- Itasca Consulting Group: Itasca's FLAC and 3DEC platforms are used for geomechanics and fractured reservoir simulation in mining and energy applications. While Itasca is strongest in rock mechanics rather than full reservoir simulation, its numerical methods expertise overlaps with ResFrac's fracture mechanics moat, making it a credible alternative for customers prioritizing geomechanics fidelity.
- COMSOL: COMSOL's multiphysics simulation platform is used in academic and applied research for coupled physics problems including fractured media and porous flow. While COMSOL is not a direct E&P enterprise competitor, its flexibility and academic adoption make it a credible alternative for research-oriented customers evaluating ResFrac's coupled fracture-reservoir capabilities.
Broad incumbents
- Emerson (Roxar): Emerson's Roxar Tempest reservoir simulation suite and broader E&P software portfolio serve the same enterprise customers as ResFrac. As part of Emerson's industrial software portfolio, Roxar competes for enterprise simulation budgets with broader automation and digital twin capabilities, often displacing point solutions in integrated deals.
- Halliburton Landmark: Halliburton's Landmark DecisionSpace and related subsurface software portfolios serve the same E&P enterprise customers as ResFrac. As one of the largest oilfield services incumbents with deep completions expertise, Halliburton offers bundled software-plus-services solutions that compete against ResFrac's standalone simulator, especially in fracture design workflows.
- SLB (Schlumberger): SLB's Petrel platform and INTERSECT high-resolution reservoir simulator are broad incumbents serving the same E&P enterprise customers as ResFrac. SLB offers a much wider portfolio (drilling, completions, production) and competes indirectly through its integrated subsurface-to-surface workflows, often displacing or surrounding point solutions like ResFrac in larger enterprise deals.
Direct peers
- Petroleum Experts (Petex): Petroleum Experts provides integrated production modeling and reservoir management software (Prosper, MBAL, REVEAL) widely used by E&P operators. While Petex focuses more on production and network modeling than fracture simulation, the two companies compete for engineering software budgets within the same enterprise customers, particularly in unconventional reservoir management workflows.
- Rock Flow Dynamics: Rock Flow Dynamics' tNavigator is a high-performance reservoir simulator that competes directly with ResFracPro for E&P simulation budgets. Both platforms emphasize coupled geomechanics and modern UI, and tNavigator is increasingly used in unconventional and fractured reservoir workflows where ResFrac currently leads.
- Computer Modelling Group: CMG is a direct competitor in reservoir simulation, offering the CMG suite (STARS, GEM, IMEX) widely used by E&P operators. While CMG has historically been strong in reservoir simulation, ResFrac differentiates through its fully coupled fracture-reservoir architecture, but they compete for the same enterprise simulation budgets and engineering teams.
