PRODUCTION FROM THE FIELD

Development

Heimdal is a field in the central part of the North Sea. The water depth in the area is 120 metres. Heimdal was discovered in 1972, and the plan for development and operation (PDO) was approved in 1981. The field was developed with an integrated drilling, production and accommodation facility with a steel jacket (HMP1). Production started in 1985. The PDO for Heimdal Jurassic was approved in 1992. The PDO for the Heimdal Gas Centre was approved in 1999, and included a new riser facility, connected by a bridge to HMP1. Heimdal is now mainly a processing centre for other fields, presently Atla, Skirne, Vale and Valemon, and for Huldra until production ceased in 2014. The Huldra pipeline to Heimdal is now used for transport of rich gas from Valemon. Heimdal also serves as a hub for rich gas transported from Oseberg to continental Europe via the Draupner platforms.

Reservoir

Heimdal produces gas and some condensate from sandstone of Paleocene age in the Heimdal Formation. The reservoir lies in a massive turbidite system at a depth of 2,100 metres and has good quality.

Recovery

The field is produced by pressure depletion.

Transport

Originally, gas from Heimdal was transported in Statpipe via the Draupner and Ekofisk fields to continental Europe. When the Heimdal Gas Centre was established, a new gas pipeline was connected to the existing gas pipeline from the Frigg field to St Fergus in the UK. Gas can now also be transported via Vesterled to St Fergus. A gas pipeline was laid from Heimdal to the Grane field for gas injection at Grane. Condensate is transported by pipeline to the Brae field in the UK sector and further to Cruden Bay in the UK.

Status

Between 2011 and 2016, Heimdal had no production of its own, but the platform was used as a gas processing centre for other fields. Most of the wells were permanently plugged in 2015. A sidetrack drilled from an existing well targets the remaining gas reserves on the field. Production from the well started in 2016. Gas from Valemon, the largest third-party user of Heimdal, will be routed to the Kvitebjørn field from late 2021. The long-term future of Heimdal is thus uncertain. A decommissioning project was initiated in 2018.
