PRODUCTION FROM THE FIELD

Development

Valemon is a field in the northern part of the North Sea, just west of the Kvitebjørn field. The water depth is 135 metres. Valemon was discovered in 1985, and the plan for development and operation (PDO) was approved in 2011. The field is developed with a fixed production platform with a simplified separation process design. The platform is remotely controlled from an operations centre onshore. The production started in 2015.

Reservoir

Valemon produces gas and condensate from Lower Jurassic sandstone in the Cook Formation and Middle Jurassic sandstone in the Brent Group. The deposit has a complex structure with many fault blocks. The reservoirs are at depths of 3900-4200 metres and have high temperature and high pressure (HTHP).

Recovery strategy

The field is produced by pressure depletion.

Transport

The wellstream is transported to Kvitebjørn for processing. Rich gas is transported through the Kvitebjørn Gas Pipeline to the Kollsnes terminal, while condensate is transported in a pipeline tied to the Troll Oil Pipeline II and further to the Mongstad terminal. Until mid-2023, the gas was exported to Heimdal.

Status

Due to production experience and rapid pressure decline in the reservoirs, the estimated recoverable volumes have been significantly reduced since the PDO. The second drilling campaign including four new production wells started in 2021, and the last of the wells came on stream in mid-2023. The production contribution from the new wells is below expectations. After closing of the Heimdal facility in 2023, permanent rerouting of the Valemon gas export via Kvitebjørn to the Kollsnes terminal was initiated.
