OSLO, Norway – Equinor has approvals for two new North Sea projects from Norway’s Petroleum Safety Authority.

One concerns use of the semisubmersible COSLPromoter for drilling eight production wells for Phase 3 of the Troll field development.

Drilling is due to start in September and continue for 144 days.

The other consent applies to use of the new Utgard field subsea facilities, pipelines, control cables and associated modifications to the Sleipner A and T platforms.

Utgard is on the median North Sea line between Norway and the UK, 20 km (12.4 mi) west of the Sleipner field center, in a water depth of 110-120 m (361-393 ft).

The plan for development and operation was approved in 2017 and centers on a four-slot subsea template with two wells tied-back to Sleipner T for processing and reduction of the carbon dioxide content in the gas.

Production is due to begin this year.
