Prof. Olav Hanssensvei 15, 4021 Stavanger, Norway

Johan Olav Helland holds a PhD in petroleum technology from University of Stavanger (2005) and an MSc in applied mathematics from University of Bergen (2001). His research interests are related to modeling and simulation of transport and multiphase flow for recovery and storage in porous media. He has developed numerical methods and pore-scale models for three-phase flow that can simulate fluid configuration, capillary pressure, trapping, hysteresis, and complex interface phenomena, directly on segmented images of the pore structure.
