Figure 7. Distribution of Paleozoic, Triassic–Lower Jurassic (prerift) plays in the North Sea rift system. The occurrence of the fields is primarily controlled by deep-seated footwall erosion during Upper Jurassic rifting (e.g., at Snorre), the rotation and transection of Triassic rift depocenters (e.g., Alwyn North), the presence of long-lived intrabasinal highs (e.g., Buchan), and doming of the North Sea during the Middle Jurassic that removed the Lower Jurassic from much of the area. Clastic Upper Triassic and Lower Jurassic sediments belonging to the Banks Group (e.g., Statfjord Formation) and Dunlin Groups (e.g., Cook Formation) form important reservoirs in the East Shetland Basin, and the Orrin Formation forms the lower part of the prospective interval in the Beatrice field of the Inner Moray Firth.
