TRONDHEIM, NorwayOKEA has issued updates on various field development projects offshore Norway in its latest results review.

The Repsol-operated Yme project (OKEA 15%) in the eastern Norwegian North Sea is in the hook-up and commissioning phase, with the jackup platform Maersk Inspirer having been installed at the field location late last year and connected to the wellhead module.

Production and injection risers between the jackup and the wellhead module have been lifted in place. The subsea storage tank and flowlines are tested and ready for operation, and the production wells are ready for start-up.

The remaining activities concern finalizing hookup and commissioning for the Maersk Inspirer and the wellhead platform. Yme is expected to come onstream during the second half of 2021.

OKEA is a partner in the current Harbour Energy-operated Ilder exploration well in North Sea license PL973, and will also participate in Equinor’s Ginny well in PL1060 this summer.

At the Draugen field in the Norwegian Sea, which OKEA operates, production has declined to 7,246 boe/d, and production availability has also been lower due to two process trips.

The E1 well was temporarily shut-in at the end of March ahead of a scale squeeze campaign planned for 3Q, although the impact should be limited as volumes will be produced by nearby wells.

A gas import project at Draugen, completed late last year, has cut diesel consumption by more than 80% with a positive impact on operating costs and the environmental footprint.

OKEA and its partners expect to take FID shortly on a tieback development of the Hasselmus gas field to the Draugen platform, 7.5 km (4.67 mi) to the southeast. First gas should follow in 2023.

The company is also working on a scheme to supply Draugen with power from shore, with the option to extend the power supply to other nearby fields.

The Draugen and Njord licensees have a joint study agreement to assess the potential shared infrastructure, and concept selection – involving a 130-km (81-mi) long subsea cable – may follow in mid-year. This could be operational in 2025.
