A new assessment released by the U.S. Geological Survey (USGS) reports on the resource potential in the area north of the Arctic Circle. Working with a number of international organizations to conduct the geologic analyses of these Arctic provinces, the USGS found that the region has an estimated 90 billion barrels of undiscovered, technically recoverable oil, 1,670 trillion cubic feet of technically recoverable natural gas, and 44 billion barrels of technically recoverable natural gas liquids in 25 geologically defined areas thought to be potential resources for petroleum.
It is the first publicly available petroleum resource estimate of the entire
area north of the Arctic Circle.
These resources account for about 2.2 percent of the undiscovered, technically
recoverable resources in the world. The Arctic accounts for about 13 percent of
the undiscovered oil, 30 percent of the undiscovered natural gas, and 20
percent of the undiscovered natural gas liquids in the world. About 84 percent
of the estimated resources are expected to occur offshore.
Of the estimated totals, more than half of the undiscovered oil resources are
estimated to occur in just three geologic provinces – Arctic Alaska, the
Amerasia Basin and the East Greenland Rift Basins. On an oil-equivalency basis,
undiscovered natural gas is estimated to be three times more abundant than oil
in the Arctic. More than 70 percent of the undiscovered natural gas is
estimated to occur in three provinces – the West Siberian Basin, the East
Barents Basins and Arctic Alaska.
The USGS Circum-Arctic Resource Appraisal is part of a project to assess the
global petroleum basins using standardized and consistent methodology and
protocol, an approach which allows for an area’s petroleum potential to be
compared to other petroleum basins in the world.
Technically recoverable resources are those producible using currently
available technology and industry practices. For the purpose of this study, the
USGS did not consider economic factors in its assessment of undiscovered oil
and gas resources. To date, the USGS is the only provider of publicly available
undiscovered, technically recoverable oil and gas
Exploration for petroleum already has resulted in the discovery of more than
400 oil and gas fields north of the Arctic Circle. These fields account for
approximately 40 billion barrels of oil, more than 1,100 trillion cubic feet of
gas, and 8.5 billion barrels of natural gas liquids. Nevertheless, the Arctic,
especially offshore, essentially is unexplored with respect to
