STAVANGER, Norway – TechnipFMC’s subsea construction vessel North Sea Atlantic has installed a subsea template at the Davlin North gasfield development in the Norwegian Sea for operator Wintershall Dea.
Dvalin North, Norway’s largest discovery in Norway, is being tied back to the Equinor-operated Heidrun platform via subsea facilities serving the Dvalin field.
The new four-slot template will house three gas production wells with the spare slot available for a future-phase development of the field.
The North Sea Atlantic transported the 290-metric ton template from the Aker Solutions yard in Egersund to Dvalin North, for installation in a water depth of 410 m, six months ahead of schedule.
The structure had been built by Mostostal Pomorze in Poland as part of the subsea production system supplied by OneSubsea and partner Aker Solutions.
In the North Sea, the semisub Transocean Norge is currently drilling the Cuvette exploration well for Wintershall Dea and partners, Petoro and DNO.
The location is close to Vega, a producing oil, gas and condensate field comprising three subsea templates, all tied back to the nearby Gjøa platform. The Cuvette well is targeting a gas condensate prospect to the south of the Vega Central template and infrastructure.
It is also designed to test overlying Upper Jurassic sandstones to help determine the potential of the nearby Orion discovery and other prospects in the area.
During the remainder of this year and into 2025, Transocean Norge is due to complete Wintershall Dea’s Maria Phase 2 wells in the Norwegian Sea and to start drilling of the Dvalin North development wells.
Under the long-term contractual arrangement, it may also be used to drill additional wells for exploration and carbon storage licenses.
