Baffin Bay Geological Survey has estimated that at least 13% of the world's undiscovered oil deposits and 30% of the world's undiscovered gas pockets are located in the Arctic, with the seas around Greenland potentially holding large amounts of natural gas and lesser amounts of crude oil and natural-gas liquids. Accordingly, the Greenland authorities have offered a large number of off-shore concessions for potential hydrocarbon (oil and gas) extraction. The largest concession-areas are located in seas west of Greenland; primarily in Baffin Bay and the Davis Strait, but with several smaller concessions in the Greenland Sea in the east also.
