The U.S. Geological Survey quantitatively assessed the potential for undiscovered, technically recoverable conventional oil and gas resources in the Cooper and Eromanga Basins of Australia (fig. 1) as part of an effort to assess priority geologic provinces of the world. By Australian convention, a basin represents an unconformity-bounded set of genetically related strata and can be vertically stacked. Thus, the Warburton (Cambrian– Devonian), Cooper (Permian–Triassic), Eromanga (Jurassic– Cretaceous), and Lake Eyre (Tertiary) Basins are stacked (Menpes and Hill, 2012), with each succeeding basin areally larger than the preceding one. For this U.S. Geological Survey assessment, the Eromanga Basin Province encompasses the Cooper and Eromanga Basins. This study assessed the potential for undiscovered conventional oil and gas resources in the Cooper and Eromanga Basins, in which more than 500 conventional oil and gas fields have been discovered since the 1960s (IHS Energy, 2015). Given the exploration maturity, most undiscovered fields are estimated to be small and in stratigraphic or combination structural-stratigraphic traps (Apak and others, 1997). For the assessment of conventional resources, the U.S. Geological Survey defined a Cooper-Eromanga Composite Total Petroleum System with Permian and Jurassic coals as the primary source rocks for oil and gas (Boult and others, 1997; Lowe-Young and others, 1997). Five assessment units (AUs) were defined within this composite total petroleum system to encompass oil and gas that were generated largely from coals and migrated and were trapped in Permian through Cretaceous reservoirs. Three AUs were defined within strata of the Cooper Basin and two within the Eromanga Basin. Most of the known gas fields are in the Cooper Basin, whereas most oil fields are in the overlying Eromanga Basin. The assessment input data for the five conventional AUs are shown in table 1.
