The subject areas for his teaching and research are experimental reservoir engineering, flow in porous media, fractured reservoirs and enhanced oil recovery methods. Presently Torsæter’s research activity is focused on wettability on pore scale and on mobilizing residual oil by using nanofluids. Ole Torsæter has a Master - degree in petroleum engineering from Norwegian Institute of Technology in 1975 and a Dr.ing. - degree from the same institution in 1983 with a thesis on water imbibition in chalk from the Ekofisk Field where he showed that Ekofisk was a good candidate for water flooding. Torsæter received the Darcy Technical Achievement Award from the Society of Core Analysts in 2014, Distinguished Achievement Award for Petroleum Engineering Faculty (2016) and Management and Information Award (2018), both from Society of Petroleum Engineers, North Sea Region. Torsæter is Member of the Norwegian Academy of Science and Technology.
