PRODUCTION FROM THE FIELD

Status

Production from Gudrun has started to decline. The Gudrun Phase II project aims to increase oil recovery by investigating new drilling targets, change of drainage strategy and other IOR measures. Tie-in of the nearby discovery 15/3-4 (Sigrun) is being evaluated.

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 in1975, and the plan for development and operation (PDO) was approved in 2010. The authorities granted a PDO exemption for the discovery 15/3-9 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.
