Geology and assessment of undiscovered oil and gas resources of the Tunguska Basin Province, 2008
The U.S. Geological Survey has evaluated the potential for undiscovered oil and gas resources of the Tunguska Basin Province as part of the Circum-Arctic Resource Appraisal (CARA). The Tunguska Basin Province includes an area of approximately 904,000 km2; less than half the area of the province lies north of the Arctic Circle. The Tunguska Basin Province includes a large part of the Siberian craton and consists of several subbasins. The province is almost completely covered by Permian to Triassic volcanic rocks. Although some oil and gas fields have been discovered and produced in the province south of the Arctic Circle, no discoveries have been made north of the Arctic Circle as of 2008. The part of this province lying north of the Arctic Circle was evaluated for undiscovered, technically recoverable, conventional oil and gas resources. Because of a low geologic probability for the occurrence of significant oil and gas accumulations (50 million barrels of oil equivalent or more), the Tunguska Basin Province north of the Arctic Circle was not quantitatively assessed as part of CARA.
