At Rock Flow Dynamics, we’re not just shaping the future of oil and gas—we’re pioneering technology for the next era of energy. tNavigator is evolving to support carbon capture and storage (CCS/CCUS), hydrogen storage, geothermal energy, wind farm optimisation and mining delivering the same high-performance simulation and integration capabilities that have made us an industry leader. From modelling subsurface CO₂ injection to optimising hydrogen storage reservoirs and simulating geothermal flow dynamics, our technology empowers innovators to develop sustainable energy solutions with confidence and precision. The energy transition demands intelligence, and we’re building the technology to lead the way.


RFD’s tNavigator is, without exaggeration, the most comprehensive one-stop-shop solution for reservoir evaluation, simulation, and management. Its capabilities go far beyond traditional modelling. Just recently, the Assisted History Matching (AHM) module enabled me to successfully tune and match an exceptionally complex, overpressured compositional model in the Caspian Sea, involving 270 equilibration regions and 24 distinct compositional models.
Beyond that, we’ve also implemented phase permeability hysteresis for gas storage using tNavigator’s flexible functionality, and we’ve based an entire integrated modelling research project for coal seam gas on this platform.
I first met the RFD team over a decade ago—back when they were already wunderkinds, outpacing the competition with raw brilliance. Since then, they’ve taken all the Herculean steps necessary to evolve from a leading simulation tool into a world-class, fully integrated reservoir management solution. And now? They’re breaking new ground in the mining sector, delivering innovative, non-standard approaches with the same elegance and efficiency that have become their trademark.
What I value most, however, is the exceptional support provided by their technical team. Every team member is brilliant—but the responsiveness and depth of knowledge shown by Andres Bracho and Zakhar Lanetc consistently exceed all expectations.
