Lowering pressure at the sandface can significantly increase production and recovery. Today, there are two main options to consider: electric submersible pumps (ESPs) and subsea multiphase boosting pumps. An approach that integrates reservoir, environment, and infrastructure considerations is necessary.

Implement reliable, low-risk subsea lift systems with an industry leader you can trust

Subsea lift technologies include a range of ESP systems that meet the demanding needs of deepwater subsea production. REDA ESP systems have been used in the first subsea wells and are now being adapted to seafloor, caissons, and in combination with other techniques including initial install for running later.

Schlumberger helped develop the first and largest subsea ESP field in the South China Sea and the first ESP installation in the ultradeep water offshore Brazil.

Jubarte Phase II comprises 15 production wells and seven injectors producing to the P-57 floating production, storage, and offloading (FPSO) platform. Wellheads are in 1,400 m of water, and each well produces to a seabed pumping module—módulo de bombeio (MoBo) in Portuguese—that houses a 1,500-hp electric submersible pump (ESP).
