TRONDHEIM, Norway  OKEA has issued an update on its projects offshore Norway in its latest results statement.

As operator, the company is developing the Hasselmus gas field in the Norwegian Sea via a single well tied back to the Draugen platform for processing and export, with startup scheduled for late 2023.

Aker Solutions is currently completing the detailed design for the topside work, with the initial topside installation due to start in the current quarter.

Subsea rock installation was completed in May, with the OneSubsea and Subsea 7 alliance progressing the next subsea phases. The COSLPromoter semisubmersible rig should start drilling the Hasselmus production well this month.

OKEA, as operator, is assessing the Aurora discovery and the Selene prospect in the North Sea based on new seismic data acquired late last year.

This has led to improved interpretation and mapping of the reservoirs, boosting confidence in the modelled volume estimates. A decision should follow shortly on whether to drill an appraisal well next year to ascertain the commerciality of the two prospects and to acquire data for a tie-in development to the Gjøa Field infrastructure.

Drilling the appraisal well could lead to a final investment decision (FID) in 2025 and a potential production start in 2026. Work also continues to mature the Neptune Energy-operated Hamlet discovery toward FID by the end of this year. The planned concept involves two production wells tied back to the Gjøa platform via existing infrastructure with a targeted start in 2025.

During fourth quarter, OKEA will participate in the Neptune-operated Calypso exploration well in the PL938 license.

At the Yme Field in the eastern North Sea, operated by Repsol Norge, the Inspirer MODU is producing from all four available production wells.

Two more production wells are being recompleted and should come online this summer, and gas and condensate are being injected into the reservoir.

Recompletion of the production wells has taken longer than expected and a leak in the recirculation line between the Inspirer and the subsea storage tank caused a shutdown of production earlier in the year. As a temporary solution, Yme is producing directly to a shuttle tanker, with a permanent repair due to be enacted shortly.

The Valaris Viking rig is on location at Beta North drilling two new production wells and will also drill an injector well at Yme Gamma. Production from Yme should subsequently ramp up to plateau in December.

Finally, at the Ivar Aasen Field in the North Sea, operated by Aker BP, an IOR campaign to bring new wells onstream should begin in the current quarter, with plans for a further IOR program in 2023. The Hanze Field tie-in development is progressing according to schedule.
