BP said it has received approval from the Oil and Gas Authority (OGA) to proceed with the Alligin development west of Shetland in the UK North Sea.

Alligin is located 140 kilometres west of Shetland in a water depth of 475 metres. It forms part of the Greater Schiehallion Area.

The Alligin development will consist of two wells, which will be tied-back into the existing Schiehallion and Loyal subsea infrastructure, utilising the processing and export facilities of the Glen Lyon floating, production storage, offload (FPSO) vessel.

The development will target 20 million barrels of oil equivalent, and is expected to produce 12,000 barrels gross of oil equivalent a day at peak. It is expected to come on stream in 2020.

BP North Sea regional president Ariel Flores said: “We announced our intention to develop Alligin in April and six months later we have achieved regulatory approval. “Alligin is part of our advantaged oil story, rescuing stranded reserves and tying them back into existing infrastructure. Developments like this have shorter project cycles, allowing us to bring on new production quicker. These subsea tiebacks complement our major start-ups and underpin BP’s commitment to the North Sea.”

The development will include new subsea infrastructure, consisting of gas lift and water injection pipeline systems, and a new controls umbilical. The wells will be drilled by the Deepsea Aberdeen rig.

Alligin (BP 50 per cent operator; Shell 50 per cent) is part of a series of infrastructure-led subsea tie-back developments in the North Sea, accessing new production from fields located near to established producing infrastructure.

Brenda Wyllie, West of Shetland and Northern North Sea area manager at the Oil and Gas Authority (OGA), said: “The Oil and Gas Authority is pleased to consent to the development of the Alligin field. This fast-tracked project will maximise economic recovery through utilising capacity in the Glen Lyon FPSO and is a good example of the competitive advantage available to operators from the extensive infrastructure installed in the UKCS.”
