OneSubsea, a Schlumberger company, has announced the successful commission and startup of subsea boosting systems installed in ultradeep waters, located in the Gulf of Mexico.
Installed in depths of approximately 7,000 ft (2,100 m), the subsea boosting systems consist of three retrievable 3.0 MW single-phase pump modules, which are landed in their pump stations, along with the subsea controls and power distribution system. Located topside is the associated pump control and instrumentation equipment with the variable speed drive and step-up transformer delivering power to the subsea equipment.
OneSubsea is known for this field-proven technology designed to increase production rates and ultimate recovery from subsea fields. By reducing the back-pressure on the reservoir, the boosting pumps have the potential to improve the recovery factor by 10% to 30%. This translates to between 50 and 150 million barrels of additional oil recovery resulting from this leading-edge subsea boosting technology.
