Evolution of subsea boosting increases production from existing and marginal fields ///

Development of the first subsea boosting systems began in the 1990s, with the intention of providing cost-effective solutions, to enable accelerated and prolonged production plateaus for economically marginal subsea fields. Subsea boosting provides the ability to tie back fields to existing production facilities, opening up greater potential for field development. Through gains in subsea boosting, the industry saw the world’s first subsea multiphase pump installed on the Shell-operated Draugen field in 1994. The pump boosted the production over a distance of 5.6 mi to the main platform from the Rogn South satellite field. The boost helped to successfully increase the production by an additional 5,000 bopd. Having accumulated approximately 1.5 million hr of subsea operational experience, these systems are capable of reliable operations in a variety of subsea applications, Fig. 1.
