Textbooks

Open Access:
	The book provides a self-contained introduction to simulating flow and transport in porous media. You will learn how to implement models and computational algorithms in a robust and efficient manner. A large number of numerical examples, all fully equipped with online code and data, allow you to reproduce results, and use them as a starting point for your own work. Cambridge University Press, 2019, ISBN: 9781108492430, DOI: 10.1017/9781108591416

Open Access:
	The second MRST textbook introduces more advanced functionality that has been recently added to the software. You will learn how to implement new models quickly and also how you can speed up your simulations with C-accelerated backends for automatic differentiation and iterative linear solvers. The book also introduces you to advanced gridding and simulation of flow in fractured media, chemical EOR, compositional flow, geomechanics, and geothermal flow. Cambridge University Press, 2021, ISBN: 9781316519967 , DOI: 10.1017/9781009019781

Professional

I work as chief scientist at SINTEF, the largest independent research organization in Scandinavia, where I head the Computational Geosciences group at the Mathematics and Cybernetics department in Oslo. I also hold a part-time Professor II position at the Department of Mathematical Sciences, Norwegian University of Science and Technology (NTNU). I have elected as a life-time member of the Norwegian Academy of Technological Sciences in 2014 and SIAM Fellow in 2020.

Research

My research interests include flow in porous media (multiscale methods, unstructured grids, grid coarsening, consistent discretizations, fast nonlinear solvers, flow diagnostics, CO2 storage, streamline methods, etc), numerical methods for nonlinear PDEs (high-resolution, front tracking, operator splitting, etc.), and heterogeneous high-performance computing (multicore, GPUs, etc).

Open source software

For many years, my research group has developed new computational methodologies for reservoir simulation. To enable other researchers to benefit from our efforts, we have compiled a MATLAB toolbox, which is released twice a year under the GNU General Public License (GPL). The toolbox has become quite popular and is used by hundreds of researchers and students worldwide. My group is also one of the key contributors to the OPM initiative, whose main goal is to provide a suite of open-source simulation tools for porous media flow developed in C++. OPM Flow will shortly be rolled out for commercial use.
