PRODUCTION FROM THE FIELD

Status

Plateau production has been short for both oil and gas, and production is now declining. Work is ongoing to maximise recovery from the field by water injection, infill drilling and additional increased oil recovery (IOR) measures. Water injection is planned to start in early 2021. It is planned that the facility will be operated with power from shore starting in 2022, as part of the electrification of the Utsira High area. Nearby discoveries and prospects may prove sufficient resources for development and tie-in to Gudrun.

Transport

Wet gas and oil are transported in separate pipelines to the Sleipner A facility. Sales gas is transported from Sleipner A via Gassled (Area D) to the market, while oil is transported to the Kårstø terminal.

Recovery

The field is produced by pressure depletion.

Reservoir

Gudrun produces oil from sandstone in the Upper Jurassic Draupne Formation and gas from the Middle Jurassic Hugin Formation. The reservoirs are complex, and uncertainties are associated with sand distribution and connectivity, especially for the Draupne Formation. The reservoirs lie at a depth of 4,000-4,700 metres and have moderate quality.

Development

Gudrun is a field in the central part of the North Sea, 50 kilometres north of the Sleipner field. The water depth is 110 metres. Gudrun was discovered in 1975, and the plan for development and operation (PDO) was approved in 2010. A PDO exemption for the discovery 15/3-9 was granted in 2013. The field is developed with a steel jacket and a topside first-stage process facility and living quarters. The field is tied-back to the Sleipner A facility with two pipelines, one for oil and one for wet gas. Production started in 2014.
