Development

Bøyla is a field in the central part of the North Sea, 28 kilometres south of the Alvheim field. The water depth is 120 metres. Bøyla was discovered in 2009, and the plan for development and operation (PDO) was approved in 2012. The field is developed with a subsea installation including two horizontal production wells and one water injection well. The field is tied-back to the Alvheim production, storage and offloading vessel (FPSO). Production started in 2015.

Reservoir

Bøyla produces oil from sandstone of late Paleocene to early Eocene age in the Hermod Formation. The reservoir has good quality and lies in a channelised submarine fan system at depth of 2,100 metres.

Recovery

The field is produced with pressure support from water injection. Gas lift is also necessary to support flow in the wells.

Transport

The well stream is transported by pipeline to the Alvheim FPSO, where the oil is stabilised and stored before it is exported by tankers. Processed rich gas is transported by pipeline from Alvheim to the Scottish Area Gas Evacuation (SAGE) pipeline on the UK continental shelf.

Status

Test production from the nearby 24/9-12 S (Frosk) discovery is ongoing. This resulted in delayed production from Bøyla in 2019 and 2020. Production from the field will also be shut-in during production testing on Frosk in 2021.
