Resumé

Drilling results of the five offshore wells suggest that the offshore southern West Greenland Basin is an area of generally normal pressure, with only limited evidence for overpressured units. The predominance of sandy or coarse clastic lithologies within the Upper Tertiary succession precludes the generation of overpressure and allows the basin as a whole to attain equalised pore pressure. However, in two of the wells, Kangâmiut-1 and Ikermiut-1, mudstones of Paleocene and Eocene age have pore pressures above hydrostatic pressure. The onset of abnormal pressures in these wells corresponds to an increase in the source potential of the mudstones. It can be concluded that the Paleocene and Cretaceous successions in the basin are likely to be overpressured where they conform to the top of the oil generative window.
