BP received the UK authorities’ nod to proceed with development of the Alligin field back in October 2018. The field is located 140 kilometers west of Shetland in a water depth of 475 meters.
Alligin forms part of the Greater Schiehallion Area and has been developed as a two-well subsea tieback into the existing Schiehallion and Loyal subsea infrastructure and the Glen Lyon floating, production, storage, offload (FPSO) vessel, BP said on Tuesday.
It is a 20 million barrels of oil equivalent field, which was originally forecast to produce 12,000 barrels gross of oil equivalent a day at peak.
The project’s performance has been better than expected, however, reaching 15,000 barrels gross of oil equivalent a day at peak since start-up in late December, according to BP.
The development has included new subsea infrastructure, consisting of gas lift and water injection pipeline systems, and a new controls umbilical.
BP North Sea Regional President, Ariel Flores, said: “Alligin is part of BP’s advantaged oil strategy, a development with a shorter project cycle time with oil that is economic to produce and low risk to bring to market. Subsea tiebacks like this complement our major start-ups and help underpin our growing portfolio west of Shetland.”
BP owns a 50 percent stake in the Alligin field, with its partner Shell holding the other 50 percent. The field is part of a series of infrastructure-led subsea tieback developments in the North Sea, accessing new production from fields located near to established producing infrastructure.
