OKEA submits North Sea Brage area development plan

OKEA provides offshore project advancements in its latest trading update.

OKEA has brought onstream the Talisker east well through the Brage platform in the Norwegian North Sea, the company said in a trading update.

Its Fensfjord north infill well project should also start production during the current quarter.

In May the company submitted an exempt development and operation application for the Sognefjord east and Kim area to the Norwegian authorities. It aims to drill a combined development and appraisal well for the area later this year.

In the Equinor-operated Statfjord area, the B-36 well on Statfjord B went online in June and is producing above expectations. A new gas-lift well is in service, with the fifth and final gas-lift well set to start up this quarter.

OKEA and Equinor are collaborating to improve production efficiency and drilling performance via sharing of best practices and operational learnings. The partners are looking to settle on a new strategy for improving longer-term production at the Statfjord Unit.

At the Var Energi-operated Gjøa area of the North Sea, although a light well intervention campaign has restored production from a shut-in well at the Gjøa Field, the gain has been offset by an integrity issue that has caused the water injection system at the Nova satellite field to be closed.

Assuming mitigation measures are successful, water injection should be reinstated by the end of the year, with a rig secured to drill a fourth water injector well at Nova shortly.

Perforation started recently of the W-1 AH water injector, and these measures to increase injectivity at the field should lead to higher oil production. A fourth oil producer is now under consideration for Nova.

Options are also under review to appraise the Aurora discovery (OKEA WI 65%) and drill the Selene prospect (OKEA WI 65%) in PL195 west of Gjøa. And operators of other tie-in candidates have approached the partners to use the Gjøa platform as a potential host.

Finally, at the Repsol-operated Yme Field in the North Sea, drilling of the C-3 infill well is close to completion, with the partners now looking to firm up further infill targets from the Beta subsea template.

Another project under review would involve artificial lift on existing wells to increase recovery and reduce production costs. Decisions should follow later this year and in 2025.
