Development

Veslefrikk is a field in the northern part of the North Sea, 30 kilometres north of the Oseberg field. The water depth is 185 metres. Veslefrikk was discovered in 1981, and the plan for development and operation (PDO) was approved in 1987. The field was developed with two facilities, Veslefrikk A and Veslefrikk B. Veslefrikk A is a fixed steel wellhead facility with bridge connection to Veslefrikk B. Veslefrikk B is a semi-submersible facility for processing and accommodation. The production started in 1989. In 1994, PDOs were approved for the Statfjord reservoir and for the reservoirs in the Upper Brent and I-segment. PDO exemptions were granted for the development of several discoveries in the years 1994-2002.

Reservoir

Veslefrikk produced oil and some gas from Jurassic sandstone in the Statfjord, Dunlin and Brent Groups. The main reservoir was in the Brent Group. The reservoir depths are between 2800 and 3200 metres.

Recovery strategy

Veslefrikk had earlier been produced with pressure support from water alternating gas injection (WAG) in the Brent and Dunlin reservoirs and with gas recycling in the Statfjord reservoir. The field was subsequently produced by depletion until shut-in.

Transport

The oil was exported via the Oseberg Transport System (OTS) to the Sture terminal. The gas was exported through Statpipe to the Kårstø terminal.

Status

Veslefrikk was shut down in 2022, and Veslefrikk B was removed from the field. Decommissioning must be completed by the end of 2027.
