Abstract
With original recoverable reserves estimated to be around 717 x 106 m3 o.e., the Ekofisk Field is the largest hydrocarbon discovery within the Upper Cretaceous–Lower Palaeocene chalk successions of the North Sea. In the Ekofisk Field, the reservoir intervals consist of overpressured and naturally fractured chalk sediments belonging to the Maastrichtian Tor and Danian Ekofisk Formation.
