PRODUCTION FROM THE FIELD

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 in the area 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 Gullfaks C, which also supplies water for injection. Seven single-well satellites and two subsea templates are tied-back to the manifold. Production started in 1994. Tordis comprises four deposits: Tordis, Tordis Øst, Borg and 34/7-25 S. The PDO for Tordis Øst was approved in 1995 and for Borg in 1999. An amended PDO for Tordis (Tordis IOR) was approved in 2005. A subsea multiphase booster pump was installed in 2007.

Reservoir

Tordis produces oil from Jurassic sandstone. The reservoirs in Tordis and Tordis Øst are in the Middle Jurassic Brent Group, and the reservoir in Borg is in Upper Jurassic intra-Draupne Formation sandstone. The reservoir in the deposit 34/7-25 S is in the Middle Jurassic Brent Group and in Upper Jurassic sandstone. The reservoirs lie at a depth of 2,000-2,500 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. Production from the Borg structure is influenced by the Statfjord field blowdown and dependent on pressure maintenance by water injection. Tordis Øst is produced with pressure support from 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 from Tordis is above expectations due to good well performance. An application for consent to extend the lifetime of the Tordis’ facilities beyond 2019 has been submitted to the authorities.
