The paper provides an overview of subsea satellite developments in Occidental’s North Sea Operations. The logic and cost effectiveness of utilizing three subsea satellites to one platform are discussed. The overall impact on recoverable reserves and related extension of economic field life are quantified and additional potential developments are described.
Occidental’s increasing commitment to subsea development is discussed. A field history is presented from the first subsea installation in 1980 to the present. The installations have grown in complexity, keeping pace with the latest technology with optimum reserve recovery as the ultimate objective.
Development of the most recent field addition, Scapa, is discussed in detail. Particular attention is given to the installation and well completion procedures with emphasis on continued improvements that have been implemented.
Occidental’s North Sea experience is put in the context of international operations and it is the authors’ belief that the subsea systems described can be a major contributory factor in increasing the number of worldwide offshore developments.
