Major Projects
Johnston has completed hundreds of evaluations, including reserves certifications, resources determinations, asset acquisitions and divestitures, farm-in opportunities, and economic appraisals. The various domestic and international evaluations have been in virtually every type of stratigraphic and structural setting covering conventional and unconventional hydrocarbon systems, including shale gas and shale oil, coal seam gas, “basin centered” tight gas, heavy oil, HPHT environments, and fracture-dominated reservoirs.
