Facilities and Technical Information

The Elgin field is located in Block 22/30b and Block 22/30c of the UK sector of the North Sea, approximately 200 km due east of Aberdeen (57° 00’42”N 01°50’16”E) in a water depth of 92m. The Franklin and West Franklin satellites are situated 5.5 km south-east of Elgin in Block 29/5b and Block 29/4d at a similar depth.

The Franklin reservoir was discovered in 1986 while Elgin was discovered five years later in 1991.  Both reservoirs are HP/HT with reservoir pressure c.1100 bar and temperature c.190oC. It was a further six years before project sanction with first oil being realised in 2001.

The Elgin Process, Utilities and Quarters Platform (PUQ) is based on the TPG 500 jack-up concept. This is a self-elevating and self-piling jack-up installation with a triangular hull in plan view. The process system on the Elgin PUQ separates gas from condensate, treats the gas to sales quality and exports the treated gas and condensate through separate pipelines.  Additionally, the PUQ has installed water treatment capacity for 8,000 bpd and gas compression power of 115MW.  To power these services, the PUQ has a power generation capacity of 60MW.  A 70-person crew operates the facilities with a maximum POB limit of 97 (bed limit).
