Installation of the two subsea pumps and associated equipment at the King field in the Gulf of Mexico sets a double world record, for both depth and distance.
At 5,500 feet below the sea's surface, the King facilities are in water almost twice as deep as the previous deepest installation of multi-phase pumps. The pumps are also positioned over 15 miles from the Marlin tension leg platform -- well over twice the previous record distance from a host platform of six miles. BP is 100 percent owner and operator of King.
The two pumps will enhance production from the King field by an average of 20 per cent. After its 2002 start-up, the King field reached peak production in 2004, with recent production averaging 27,000 barrels of oil equivalent a day. In addition to the increase in production, this project will allow a seven per cent increase in recovery factor, extending the economic life of the field by five years.
"In line with our strategy to maximize reserves from our existing fields, the application of this cutting edge technology across BP's large deepwater portfolio has the potential to unlock significant resources that would otherwise remain unrecoverable," said Andy Inglis, BP's Chief Executive of Exploration & Production.
Oil and gas production naturally declines as reservoir pressure drops. Subsea boosting can reduce well back-pressure, thus improving reservoir recovery and increasing hydrocarbon flow rate. In addition, multi-phase pumping extends the distance over which the well stream can be transported -- increasing the step-out distances from existing infrastructure.
King is tied back to the Marlin TLP, which is approximately 75 miles offshore Louisiana in Viosca Knoll Block 915. King is located in Mississippi Canyon 84.
The deepest subsea pump installation until King was at 3,000 feet and the furthest from its host facility was previously six miles.
