A mid-Cretaceous prograding sedimentary complex in the Sisimiut Basin, offshore West Greenland—stratigraphy and hydrocarbon potential

A prograding and aggrading depositional system has been mapped from seismic data in the Sisimiut Basin, offshore West Greenland. Seismic stratigraphic analysis resulted in mapping of three seismic sequences and internal boundaries. Mounds at the base of the prograding sequences may represent massflows, which could be prospective. The sealing deposits are Cretaceous claystone, indicated by correlation to the Ikermiut-1 well. Local closures of mounds, regional seal and hydrocarbon traces in the region indicate a potential for stratigraphic hydrocarbon leads. Amplitude interpretation indicates possible mass-flow deposits within the sequences as well as half-graben syn-rift deposits below, both of which may be prospective.
