Geology and assessment of undiscovered oil and gas resources of the Lena-Anabar Basin Province, 2008

The U.S. Geological Survey (USGS) assessed the potential for undiscovered oil and gas resources of the Lena-Anabar Basin Province as part of its Circum-Arctic Resource Appraisal program. The province is in the Russian High Arctic and is located between the Laptev Sea and the Siberian craton. Three assessment units (AUs) were defined for this study—the Lena-Anabar Basin AU, the Lena-Anabar Basin Updip AU, and the Sukhan-Motorchun Riphean Rift AU—and were assessed for undiscovered, technically recoverable resources. The estimated mean volumes of undiscovered oil and gas resources for the Lena-Anabar Basin Province are ~2 billion barrels of crude oil, ~2 trillion cubic feet of natural gas, and <1 billion barrels of natural gas liquids. All of the undiscovered petroleum resources are north of the Arctic Circle.
