PRODUCTION FROM THE FIELD

Høykontrast Modus

Development

Tordis is a field in the Tampen area in the northern part of the North Sea, between the Statfjord and Gullfaks fields. The water depth is 150-220 metres. Tordis was discovered in 1987, and the plan for development and operation (PDO) was approved in 1991. The field has been developed with a central subsea manifold tied-back to the Gullfaks C facility, which also supplies water for injection. Seven single-well satellites and two 4-slots subsea templates are tied-back to the manifold. Production started in 1994. Tordis comprises four structures: Tordis, Tordis Øst, Tordis Sørøst (34/7-25 S) and Borg. The PDO for Tordis Øst was approved in 1995 and for Borg in 1999. An amended PDO for Tordis was approved in 2005.

Reservoir

Tordis produces oil from Jurassic sandstone. The reservoirs in Tordis and Tordis Øst are in the Brent and Statfjord Groups, and the reservoir in Borg is in Upper Jurassic intra-Draupne Formation sandstone. The reservoir in Tordis Sørøst is in the Brent Group and in Upper Jurassic sandstone. The reservoirs lie at a depth of 2000-2500 metres and the reservoir quality is good to excellent.

Recovery

The field is produced by pressure support from water injection and by natural aquifer drive.

Transport

The well stream from Tordis is transported via two pipelines to the Gullfaks C facility for processing. The oil is exported by tankers, while the gas is exported via Statpipe to the Kårstø terminal.

Status

Production is maintained through pressure support and well interventions. A production well drilled on Tordis in 2020, and a new well planned for 2021, will contribute to increased production. New 4D-seismic data to be acquired in 2021 will be used to map further infill drilling targets.
