Personal profile
Research interests
Hariharan Ramachandran is working as a Research Associate at the Institute of GeoEnergy Engineering. His current research focusses on derisking subsurface storage reservoirs. Specifically, he is working on fault representations within large-scale models to analyze fault leakage and how parameters uncertainty affects it.
Hariharan was formerly employed as a postdoctoral researcher at UiT-Arctic University of Norway's Centre of Arctic Gas Hydrate, Environment and Climate (CAGE), where he focused on examining methane seepage and related gas hydrate systems in the west-Svalbard margin.
He received a Ph.D. and MS in Petroleum and Geosystems Engineering from The University of Texas at Austin (USA) and a B.Tech in Chemical Engineering from Anna University in Chennai (India). In his doctoral studies, he explored how phase changes affect CO2 leakage through faults/fractures.
