Jorge Oniszczuk is a Reservoir and Completions Engineer at ResFrac, where he applies dynamic modeling and reservoir evaluation expertise to help operators optimize well performance across conventional and unconventional assets.

Prior to joining ResFrac, Jorge held reservoir engineering roles at TotalEnergies and Tecpetrol, where he focused on dynamic modeling, well performance, and reservoir evaluations for conventional and unconventional projects. He has also developed Python and machine learning applications for oil and gas, integrating data science techniques into reservoir engineering workflows.

Jorge earned his Petroleum Engineering degree with honors from the Instituto Tecnológico de Buenos Aires (ITBA). Before university, he was a National Physics and Chemistry Champion in Argentina.

Jorge resides in Buenos Aires, Argentina, and is is an avid cyclist and a passionate photographer.

FracTest – An Online Tool for DFIT Interpretation

This week, we are releasing FracTest, a web-based application for interpretation of diagnostic fracture injection tests (DFITs). FracTest is available at resapps.resfrac.com, alongside our other two ResApps, StageOpt and IntTest. DFITs are small-volume fracture injection tests used to estimate stress, pore pressure, and permeability. These quantities form the foundation of the fracture and reservoir engineering work that we do in ResFrac, and so we view DFIT interpretation as one of the most important parts of our workflow.

Congratulations to Fervo on their IPO!

This week, I attended ResFrac customer Fervo Energy’s IPO on the Nasdaq. The positive energy was incredible. Roughly 100 people were there: Fervo employees, family, and members of the wider Fervo-supportive community. I was invited because ResFrac provides our software and services to Fervo, and also because I have been an advisor to the company since before its founding. As Jack reminded me this week, I introduced him and Tim! They founded Fervo around the same that ResFrac was being first released commercially, and they played an important role for our company because they were one of our earliest customers, and in turn, we were one of their first partners and vendors. Ever since then, ResFrac has been a core part of Fervo’s workflow in doing stimulation design and reservoir engineering.

ResFrac, a Leader in Advancing the Future of Subsurface Simulation, Receives Platform Investment from Banneker Partners

Banneker Partners (“Banneker”) today announced a platform investment in ResFrac Corporation (“ResFrac”), the developer of the industry’s only fully integrated reservoir simulation and hydraulic fracturing platform. ResFrac uniquely couples reservoir simulation and hydraulic fracture modeling, enabling engineers to model a well’s entire life cycle, from the moment rock is fractured through years of production, in a single, continuous simulation. This precision allows energy operators to test thousands of design scenarios in a virtual environment, optimizing completion design and maximizing resource recovery while minimizing capital risk.
