The Troll field off the shore of Norway is one of the largest natural gas and oil fields in the Norwegian sector of the North Sea, holding 40% of Norway’s gas. The area west of the field also possesses significant quantities of oil in thin zones under the gas cap.
The reservoir is located in three eastward-tilted fault blocks 4,921 ft (1500 m) below sea level. It consists of cyclic sandstones from the Fensfjord, middle Heather, Sognefjord, and upper Heather formations in the Jurassic Viking group, and is overlaid by Upper Jurassic to Paleocene clays.
