Researcher biography
Ray is currently Professor of Well Engineering & Production Technology in the School of Chemical Engineering and Energi Simulation Co-chair in the Centre for Natural Gas. There he is researching projects related to low permeability, unconventional reservoirs (i.e., tight gas, coal seam gas, shale gas reservoir). In addition, he is an instructor and course coordinator in several courses in the ME Petroleum Engineering program at the University of Queensland.
Outside of teaching and research, Prof Johnson is the Principal at Unconventional Reservoir Solutions, a provider of reservoir engineering, stimulation consulting, and training services to the petroleum and mining industry, focusing on unconventional resources such as gas or oil from coal, shale, or naturally fractured reservoirs.
From 2014 to 2020 Ray was an Adjunct Associate Professor at the ASP, University of Adelaide.
