Norwegian offshore block 31/2 was awarded to a group of 5 companies during the fourth round allocation in 1979 under license 054. Norske Shell A/S is the operator with a 35% share. The other partners are Statoil (50%), Norsk Hydro Production A/S (5%), Norsk Conoco A/S (5%), and Superior Oil Norge A/S (5%). Six wells have been drilled to date, and additional appraisal wells are planned. Block 31/2 is located ca. 80 km due west of Bergen in the Norwegian trench, and contains a large gas accumulation underlain by a thin oil layer. The development of these reserves will have to cope with several major challenges, the most significant of which are the following: water depth of between 320 and 350 m; soft seabed; shallow reservoir which extends over a large area; and hostile environment. These considerations imply that several areas of technical development need to be resolved before a field development plant can be finalized. This study discusses the requirements for subsea completion technology.
