About the field

WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE

Development
Blane is a field in the southern part of the Norwegian sector in the North Sea, 35 kilometres southwest of the Ula field. The field is located on the border to the UK sector and the Norwegian share of the field is 18 per cent. The water depth is 70 metres. Blane was discovered in 1989, and the plan for development and operation (PDO) was approved in 2005. The field has been developed with a subsea facility on the British continental shelf with two horizontal production wells tied-back to the Ula field. The production started in 2007.
Reservoir
Blane produces oil from Paleocene sandstone in the Forties Formation. The reservoir is at a depth of 3100 metres and has moderate to good quality.
Recovery strategy
Until 2019, the field was produced with pressure support from injection of produced water from the Blane, Tambar and Ula fields. The field is now produced by pressure depletion. In addition, gas lift is used in the wells.
Transport
The well stream is transported by pipeline to the Ula field for processing. The oil is exported further to Teesside in the UK.
Status
Production from the field has generally been good, but the water cut is increasing. The production is restricted by sufficient gas from Ula available for gas lift, by oil-in-water limits and other technical problems.
