A/S NORSKE SHELL has found super giant reserves of oil and gas in Block 31/2 and adjacent blocks in the Norwegian North Sea. But development of the discovery poses staggering problems--the field lies in more than 1,000 ft of water in an area noted for violent weather. Even though conventional technology will be used wherever possible, Block 31/2 development involves severe technical and financial risk. Because of the areal extent of the reservoir and constraints on directional drilling, both template and satellite wells will be used. The choice between wireline and through flowline (TFL) servicing has not been finalized, but TFL completions seem to offer better flexibility. The choice of control systems is between the reliability inherent in completely hydraulic systems or the quick response time of electro-hydraulic controls. Underwater connections will be made without the aid of divers, possibly by using a surface-controlled sled, patterned after the one developed for the Shell Expro Cormorant UMC system. This two-part series is operator A/S Norske Shell's first official word on development of the field. Part 1 focuses upon fundamental decisions involving well location and subsea equipment. Part 2, which will be published next month, examines deepwater platform technology.
