Troll West


Although Troll is primarily a gas field - one of the biggest in the North Sea, holding 60% of Norway's gas reserves - it also possesses significant quantities of oil, in thin zones under the gas cap, to the west of the field. The field as a whole consists of the main Troll East and Troll West structures in blocks 31/2, 31/3, 31/5 and 31/6, about 65km west of Kollsnes, near Bergen, in water depths of 315-345m. Most of the gas lies in Troll East.
