Description
Description TypeTextDate updatedDevelopmentSkirne, including the Byggve deposit, is a field in the central part of the North Sea, 20 kilometres east of the Heimdal field. The water depth is 120 metres. Skirne was discovered in 1990, and the plan for development and operation (PDO) was approved in 2002. The field has been developed with two subsea templates tied to the Heimdal facility. Production started in 2004. The Atla field was tied-back to Skirne in 2012.14.02.2020ReservoirSkirne and Byggve produce gas and condensate from Middle Jurassic sandstone in the Brent Group. The Skirne deposit lies at a depth of 2,370 metres and the Byggve deposit at 2,900 metres. The reservoir quality is good.16.03.2018RecoveryThe field is produced by pressure depletion.11.04.2017TransportThe well stream from Skirne is transported in a pipeline to the Heimdal facility for processing. The gas is transported from Heimdal in the Vesterled pipeline to the St Fergus terminal in the UK. Gas was previously also sent through Statpipe to continental Europe. Condensate is transported to the Brae field in the UK sector and further via the Forties pipeline system to Cruden Bay in the UK.25.04.2019StatusThe field is now in its tail phase. Skirne had only been producing for few days in 2022.The Byggve reservoir is flooded by formation water, and there is no more recoverable gas. A decommissioning plan was submitted in 2015, and work is ongoing to plan for decommissioning and removal.03.02.2023 -
