SAPEX Limited (a company that forms part of the Tri-Star Petroleum Group) has proposed to use fracture stimulation techniques on petroleum wells in PELs 122 & 123 in the Arckaringa Basin of South Australia. SAPEX intends to evaluate the size and commerciality of the oil and gas resources within target shale formations including the Stuart Range and Boorthanna Formation. Shale targets are expected to range between 650m to 1,800m deep, and are located approximately 100 km away from the Coober Pedy Township. This report details the Department for Energy and Mining – Energy Resource Division (DEM-ERD) review of the Environmental Impact Report (EIR) and draft Statement of Environmental Objectives (SEO) for fracture stimulation in the Arckaringa Basin as proposed by SAPEX.
