Project Description
The Dunlin field is located on Blocks 211/23a and 211/24a in the UK sector of the North Sea about 311 miles (500 kilometers) northeast of Aberdeen within the East Shetland Basin and seven miles (11.2 kilometers) from the boundary line with Norway. Fairfield Energy operates the field with a 30 percent stake; while Mitsubishi holds the remaining interest.

Dunlin was discovered by Shell UK with well 211/23a-1 in 1973, its eastward extension into 211/24 being confirmed by Conoco late in 1973.

Field Development

Dunlin’s field development consists of 10 production wells and two injection wells connecting to the Dunlin platform. The field came online in August 1978 and reached a plateau of about 120,000 bopd early in field life.

Field Development

Dunlin’s field development consists of 10 production wells and two injection wells connecting to the Dunlin platform. The field came online in August 1978 and reached a plateau of about 120,000 bopd early in field life.

During the following years there was an active program of drilling and approximately 100 wells have been drilled from the Dunlin platform. Dunlin relies on consistent water injection to maximize recovery. In 2001 the Dunlin Platform became fuel gas deficient and the result was a marked reduction in production caused by a reduction in water injection.

Satellite Fields

The Dunlin SW field was discovered in 1973 with the 211/23a-2 well, but was not brought on to production until 1996 when an extended reach well was drilled from the Dunlin Platform. A second infill well was drilled in 1998. Both wells are currently producing. The field receives pressure support from distal Dunlin field injection wells.

The Osprey field, five miles (eight kilometers) to the northwest of Dunlin, was discovered through appraisal well 211/23a-3 in 1974. The discovery has been developed as a subsea tie-back to Dunlin with first production in January 1991.

The Merlin field was discovered by the first sidetrack of exploration well 211/23a-13 in February 1997. Following development approval in August 1997, the field commenced production in November 1997 as a subsea tie-back to Dunlin. Subsequent development in 1999 saw the installation of water injection, along with a second production well. A third production well was drilled in 2001.

Status Updates
Fairfield Optimistic About Dunlin Enhancements
Type: Operator Update

Oct. 2012 - To date, Farifield Energy has invested $113.3 million in an effort to revitalize the Dunlin platform. For the first time since early 2000, the operator will be able to use its own independent power generation system to achieve significantly higher and sustained water injection performance. A new fuel gas import system and modified water injection system are expected to boost production of the mature field to around 10,000 bopd. Additional work has included platform and subsea modifications and a recent acquisition of a new 3D seismic survey over the field. The data will help support an exploration program that could result in additional wells being drilled and tied-back to the platform.

Oil Spill at Osprey Field
Type: Status Update

Jul. 2012 - An oil spill has occurred on the Osprey field in the UK sector of the North Sea, confirmed the Department of Energy and Climate Change. The spill, reported on Friday by Fairfield Energy, was discovered when a hydrocarbon sheen was seen in the vicinity of the Osprey subsea manifold which feeds back to the Dunlin Alpha installation. Fairfield said that two on-line wells at Osprey have been closed in response to the spill. The firm and its partners are making efforts to identify the source of the oil, and a specialist vessel with a remotely-operated vehicle onboard is being mobilized to the location of the spill. An ongoing series of aerial observations is also taking place. Fairfield estimates that up to 8.7 tons of oil has been released into the sea.

Technip to Construct Dunlin Fuel Gas Pipeline
Type: Contract Award

Aug. 2010 - Fairfield Energy awarded a contract to Technip for the provision of Subsea Engineering, Procurement, Construction and Installation (EPCI) services for the Dunlin Fuel Gas pipeline project. The construction of this gas import pipeline will allow the Dunlin platform to become fully self sufficient in fuel gas, leading to a much improved power generation capability, stated Fairfield. The project entails Dunlin being connected to a long-term fuel gas supply via the Thistle-Don pipeline, currently operated by EnQuest PLC. This will result in improved volumes of reservoir water injection in order to further increase the oil production from three fields: Dunlin, Osprey, and Merlin. Dunlin is located on Blocks 211/23a and 211/24a in the UK sector of the North Sea.
