Summary Information
- Operator: BP
- Country: UK
- Location: In the Atlantic, 100 miles to the west of Shetland and Orkney
- Production start: 1998
- Partners: BP (33.3%) with Shell (44.9%), Harbour Energy (10.0%) and Ithaca Energy (11.8%)
- Type: Oil
- Estimated Reserves: recoverable reserves of 340 million barrels of oil at start up

Description
- Schiehallion lies in 375 metres water depth in UK blocks 204/20, 204/25a, 204/25b, 205/16 and 205/21b and has recoverable reserves of 340 million barrels of oil.
- The Schiehallion development centred on 29 seabed wells in four drilling centres, producing oil via manifolds through steel pipelines and then flexible risers into the purpose-built Schiehallion FPSO, a floating production, storage and offloading vessel.
- The development was based upon producing 340 million barrels contained within the main field and a further 85 million barrels from the Loyal reservoir which overlies it.
- Peak production of 154,000 barrels of oil a day is expected and the FPSO could store over 900,000 barrels.
- Gas is transported on the West Of Shetlands Gas Pipeline System
- The field was redeveloped in the Quad 204 Redevelopment Project which utilises the Glen Lyon FPSO
- The Alligin development has included new subsea infrastructure, consisting of gas lift and water injection pipeline systems, and a new controls umbilical.
