The Shell operated Pierce oil field is located in Block 23/22a and lies 165 miles (265km) East of Aberdeen, Scotland, in the Central North Sea area of the UK Continental Shelf, in water depths of approximately 262 feet (85m).
The field was discovered in 1975, with first oil achieved in February 1999. Ithaca Energy acquired its 7.48% non-operated working interest in the Pierce field from Sumitomo Corporation in July 2014.
The field is developed by subsea wells tied into the Haewene Brim floating production, storage and offloading (FPSO) vessel. Oil is exported directly to market via shuttle tankers. After a significant redevelopment project due to complete in 2022 produced gas previously injected will now be transported to shore for sale.
