Kosmos Energy has tapped Schlumberger's OneSubsea to perform engineering, procurement, construction, and installation (EPCI) for the supply of a subsea multiphase boosting system for the Odd Job field in the deepwater Gulf of Mexico.
OneSubsea, the subsea technologies, production, and processing systems business of Schlumberger, will supply the system, topside equipment, and a 16-mile integrated power and control umbilical.
Project management, engineering, assembly, and testing will be performed at the OneSubsea facilities in Bergen and Horsøy, Norway, while transport to the field and installation will be carried out by OneSubsea partner Subsea 7.
“The system will be tied back to the existing facility, thereby achieving significant cost and energy savings, as well as reducing CO2 emissions, all while improving Kosmos Energy’s ultimate recovery,” said Don Sweet, director, Subsea Production Systems.
Since 1994, OneSubsea has delivered some 115 subsea boosting pumps. It has been shown that the application of subsea multiphase boosting can increase production rates by 20% to more than 200%, in addition to a substantial increase in total recovery as backpressure on the reservoir is offloaded by a seabed processing system.
Odd Job is in Mississippi Canyon Blocks 214 and 215. Kosmos is the operator and holds a 54.9% working interest in the field. The field was part of the company’s $1.2-billion purchase of Deep Gulf Energy in 2018 and its entry into the Gulf of Mexico market. The field is a multiwell subsea tieback to the Delta House floating production system in Mississippi Canyon Block 254.
