Experimental Julia framework for fully differentiable multiphysics simulators based on implicit finite-volume methods with automatic differentiation.
Modelling and simulation of flow in porous media
The theory of flow through porous media constitutes a fundamental approach for unravelling the intricate behaviours of fluids in complex structures characterized by interconnected voids and solid matrices. By utilizing partial differential equations and transport equations, this modelling enables us to capture the diverse factors that influence fluid flow, including porosity, permeability, and pressure gradients. Such models find applications in diverse fields, from predicting groundwater movement in hydrogeology or geo-energy applications to optimizing filtration processes in chemical engineering.
What do we do?
A major part of our research aims at developing enabling simulation technology for improved and enhanced hydrocarbon recovery and carbon storage. To accelerate innovation, we have had a long-time, strategic focus on delivering and disseminating our research through open-source software:
- Our open-source software, MRST, developed over almost two decades, is a unique research tool used by scientists, engineers, and students all over the world to prototype and develop new computational methods and test and validate them in a well-established and relevant environment. (The many hundred scientific papers featuring MRST testify to its pouplarity). Unlike many other simulators, MRST also offers the possibility of computing sensitivities using adjoints.
- The OPM Flow simulator is used commercially by Equinor on real assets. We offer professional support and maintenance for this software together with our partners from NORCE and OPM-OP.
Over the years, we have researched many different problems and computational methods. The MRST website contains descriptions of some examples, including multiscale methods and novel ideas like flow diagnostics. You can also watch an overview lecture that explains the history and the capabilities of the MRST software (90 min version, 30 min version).
The GeoScale website documents activities from the early years of the research group.
