Reid Grigg heads the Gas Flooding Processes and Flow Heterogeneities Group at the PRRC and is an Adjunct Professor in the Petroleum and Chemical Engineering Department at New Mexico Tech. His research interests are:

  • Enhanced oil recovery (EOR), carbon sequestration, and gas hydrates.
  • Phase behavior of pressurized geological formation fluids, fluid properties and flow behavior of high-pressure liquids and gases, and high-pressure/high-temperature/high-flow rate gas flooding process in porous media.
  • Gas injection for improved oil recovery and greenhouse gas sequestration, reservoir fluid phase behavior, and flow behavior of multi-phase systems; their effects on flow in porous media; and improving and understanding mechanisms for improved mobility control.
  • Emphasizing laboratory tests augmented with field test and modeling.
The group's research is focused on improving and understanding mechanisms for improved mobility control in oil reservoirs and carbon sequestration storage. Before joining PRRC in 1992, Grigg worked for Conoco for over 10 years as a research scientist and chemist, and he spent a year with Core Laboratories before joining the PRRC. He obtained his PhD in physical chemistry from Brigham Young University and has authored over 100 publications. He is a member of the Society of Petroleum Engineers, the American Chemical Society, and Sigma Xi.
