Alligin is a 20 million-bbl recoverable oil field in the Greater Schiehallion area about 140 km west of Shetland in 475 m of water (OGJ Online, Oct. 22, 2018).

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.

Originally forecast to produce 12,000 boe/d (gross) at peak reached 15,000 boe/d (gross) at peak since start-up.

The development includes new subsea infrastructure consisting of gas lift and water injection pipeline systems and a new controls umbilical.

Alligin is operated by BP with 50%. Shell is partner with the remaining 50%.
