Overview
Background
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.

Unconventional Reservoir Appraisal and Development Strategies
Ray's research focuses on integrating elements of reservoir engineering, geomechanics and hydraulic fracturing to improving appraisal and development strategies for unconventional resources such as gas from coal as well as oil and gas from shales and naturally fractured reservoirs.
Research impacts
A lot of people state that they are researching or investigating hydraulic fracturing, which in most cases is limited to modelling some aspect of rock fracture mechanics or fracture propogation in some geological or rock mechanical framework. Whist this may progress the science of hydraulic fracture propagation, hydraulic fracturing design optimisation in a petroleum well stimulation context is not that concise, exact or simple!
Well stimulation in the petroleum industry context is much larger and represents an overall process to create an economic outcome from a low-permeability reservoir by implementing the proper selection of fluids, stage/job placement, proppant selection, onsite job execution, post-frac clean-up and long term production management along with the hydraulic fracturing modelling, a small portion of the process. It is an overall design, execute, and then evaluate process that cannot be optimised by a discrete element model.
My research benefits societies' need to identify and develop unconventional resources as a part of it's overall energy mix by effectively implementing economical hydraulic fracturing solutions in unconventional reservoirs. Advances of my research integrating geomechanics, hydraulic fracturing, reservoir engineering, and production technology will aid us in maintaining low cost energy thereby benefitting overall economic growth in Australia by economically unlocking more of Australia's unconventional gas resources (i.e., tight gas sandstone, shale gas, and coal seam gas reservoirs).
