Baker Hughes has installed Centrilift XP™ enhanced run life electrical submersible pumping (ESP) systems in two vertical subsea boosting stations located on the seabed at Shell’s Perdido field in the Gulf of Mexico in 8000 ft of water.
The pumping systems at Perdido are designed to boost up to 125 000 bpd of fluid. Baker Hughes was awarded the contract for five enhanced run life systems, engineering design and qualification and testing services for Perdido in 2007. The remaining three ESP systems are scheduled for installation later this year.
Perdido, which began producing in March, is the world’s deepest application of a full scale seabed separating and boosting system. The 1600 hp. ESP systems, designed to overcome the challenge of lifting liquids 8000 ft from the seafloor to the production platform, are installed in five, 350 ft caissons connected directly to the platform’s production risers. The caissons are located near the spar production facility. Each caisson also is equipped with cylindrical cyclonic gas separation systems to separate natural gas entrained in the fluids before the fluids enter the ESP system. The boosting systems handle production from three subsea satellite fields tied back to the Perdido spar (Great White, Silvertip and Tobago).
Shell designed and operates the Perdido development on behalf of partners Chevron and BP.
