Simulation services to maximize return on investment
Turnkey fracture design and reservoir simulation services
Our hydraulic fracturing and reservoir simulation solutions apply to a broad range of applications
Following the right modeling workflow is critical for a successful project. Every ResFrac project includes a series of ‘checkpoint’ meetings at key junctures to keep stakeholders aligned and ensure strong engineering design principles.
Model construction and setup
Ingest data, set up an initial model, and present back to confirm everything has been communicated successfully.
Determine ‘key observations’ to be matched from field data. Plan the calibration process in advance. Then, vary parameters to achieve a match.
Align on the design variables to optimize. Perform a quantitative optimization for NPV, investment efficiency, or any other objective.
Design field implementation
Establish baseline performance expectations. Establish performance metrics, and try to minimize uncontrolled variables.
Compare actual production with predicted. What are the ‘key observations’ from the field data? How do they align with expectation? If there is variance, what are potential causes? Are there additional design changes to consider next?

Recorded ARMA HFC 2023 Series Presentation– Optimization of Perforation Phasing for Improving Uniformity of Proppant Distribution Between Clusters
This ARMA Hydraulic Fracturing Community (HFC) presentation summarizes the work on proppant transport in horizontal perforated wellbores. Specifically, it discusses the model for proppant distribution between perforations depending on their orientation and location within the stage, optimal configurations are proposed, and performance is evaluated.
ResFrac at the Breckenridge Imperial Challenge
It’s that time of year again for our ResFrac team to embark upon the Imperial Challenge in Breckenridge, CO! As with last year, Egor, Dirk (ResFrac investor), and Garrett tackled the challenge this year. The Imperial Challenge is an annual triathlon where racers bike or run from the town of Breckenridge 6 miles and 850 feet up to the base of the Breckenridge ski resort, then skin (ski uphill) 3000 ft to the peak of the resort at 12,998 ft, then… ski off the other side.
Technical barriers for deep closed-loop geothermal
This is the most exciting time in my lifetime for geothermal. There are many, many innovative things happening. To name a few – promising new approaches to Enhanced Geothermal Systems, geothermal projects in sedimentary and lower enthalpy formations, new approaches for geothermal exploration, lithium extraction from produced brines, geothermal energy storage, integrations with CO2 storage and capture, and new technologies for producing energy from hot water that is coproduced with oil and gas. However, this post is about a concept about which I remain skeptical – deep closed-loop heat exchangers (McClure, 2021). These designs are sometimes called ‘Advanced Geothermal Systems,’ AGS (Malek et al., 2022).
