Dr. Mehta co-leads the In-Situ Combustion Research Group, with Dr. R.G. Moore, which consists of 11 full-time researchers and more than 10 to 15 graduate students.

The following are some of his current research interests:

  • In-situ combustion/high-pressure air injection based improved oil recovery processes
  • Gas-phase combustion in porous media
  • Safety aspects of underbalanced drilling
  • Physical simulation of thermal IOR and hybrid processes
  • Safe mixing of explosive mixtures in porous media at high pressure/high temperature (HP/HT)
  • Flammability limits of complex mixtures at HP/HT
  • Remediation of petroleum waste by low temperature oxidation (LTO)
  • Thermal well stimulation technologies and downhole tools
  • Physical modeling of combustion processes for gas turbines
  • Combustion of hydrocarbons, including bitumen emulsions
  • Underground gas storage for energy
  • Field implementation of IOR technologies
  • Physical simulation and analysis of pipeline explosions
  • HP-HT PVT and phase behavior


Dr. Sudarshan A. Mehta holds a BEng and MSc in mechanical engineering, and a PhD with a specialization in oil sands combustion technology from the University of Calgary. Since 1990, and prior to his formal academic appointment at the University of Calgary, Dr. Mehta has been an instrumental supporter of internationalization within the Department of Chemical and Petroleum Engineering at the University of Calgary and the Canadian petroleum industry.

He also serves as a consultant to Canadian and international energy companies in the areas of improved oil recovery (IOR) and drilling and completion safety, and is a co-founder and director of Hot-Tec Energy Inc. He has authored or co-authored over 300 technical articles, reports and patents. Dr. Mehta has organized and taught a number of courses on thermal IOR and advanced drilling technology internationally.

Dr. Mehta is the recipient of a number of local, national and international awards of excellence. He is a member and active volunteer of the Society of Petroleum Engineers International (SPE), APEGA, The Combustion Institute and Canadian Heavy Oil Association (CHOA), Canadian Association of Drilling Engineers (CADE), IRP 18 Committee of Drilling and Completions Committee of CAPP, and is a registered professional engineer in the Province of Alberta.
