The Nuussuaq peninsula in West Greenland is located in the northern part of the Disko Bay region. The Nuussuaq peninsula is characterized by its spectacular geology, exposing huge sections of sedimentary formations and seismic scale incised valley complexes. Topping the sedimentary sequence on the Nuussuaq peninsula is the flood basalts of the West Greenland Basalt Group.
The peninsula is geologically situated in the northerly region of Nuussuaq Basin and for decades it has been subject to research and investigations into the peninsula’s petroleum potential. Work has particularly been by GEUS (the Geological Survey of Denmark and Greenland), who have studied extensively the structural/stratigraphic evolution of the Nuussuaq Basin. Drillings in a petroleum exploration context also took place in the 1990s on the Nuussuaq peninsula, with one exploration well, GRO#3, being drilled and a number of slimcore wells by the company Grønarctic.
The Nuussuaq peninsula is highly interesting from a petroleum exploration perspective. Sandy formations crop out extensively in the sub-basaltic sequence and can be observed in the Aaffarsuaq valley of the Nuussuaq peninsula and in particular along the south coast of Nuussuaq. Seal formations are known to exist both from penetrated exploration wells in the offshore environment and from outcrops on the Nuussuaq peninsula. Five oil types have been identified on the peninsula by GEUS, of which two, the Itilli oil of marine origin, and the Maarraat oil of deltaic origin, are of major importance in an exploration context. Furthermore, a large structure – the Q1-lead - has been identified and mapped in the central western part of the Nuussuaq peninsula.
Currently, the Oil & Gas Department at the Government of Greenland is running an open door round for the onshore areas of Nuussuaq and Disko.
