Equinor and its partners are working on a concept for a Phase 3 development of the giant Johan Sverdrup Field in the Norwegian North Sea, said partner Aker BP in a trading update.
This would add further subsea wells, tied back to the central platform complex via existing infrastructure.
Drilling continues for the current Phase 2, both from the field center and the Phase 2 subsea templates. So far this year, four new production wells have come onstream with up to six more to follow in the second half of the year, raising the total number of production wells across the field to 41.
Planning is also underway for a campaign in 2025 to drill new multilaterals in existing production wells.
At Yggdrasil, Aker BP’s new multi-field development in the North Sea, the first five subsea templates have been installed, and a geo-pilot well has been completed at the Frigg Gamma structure.
Results should help reduce risk and optimize well placement for the project. Aker BP and its partners also aim to select their preferred concept later in the year for the 2023 oil discovery Øst Frigg Beta/Epsilon, for inclusion in the development.
In the Alvheim area of the North Sea, the three-well drilling program for the Tyrving development has finished, with final subsea tie-in operations in progress. Tyrving should start production ahead of schedule in October.
Having brought online a new infill well at the Alvheim Field in early May, Aker BP is now assessing a further infill target, and it expects to take FID during te fourth quarter.
Preparations are underway at the Tambar Field in the southern Norwegian North Sea for a new side-track well, likely to be drilled in late 2024 alongside recompletion of another production well.
In the same area, installation recently finished of the jacket for the new Fenris platform and the production pipeline. Fenris is a gas field undergoing development via a tieback to the Valhall complex; drilling is due to start in the current quarter.
Finally, in the Skarv area of the Norwegian Sea, Aker BP has revised upward its resource estimate for the Adriana structure in production license 211CS, following an appraisal well earlier this year, to 23 MMboe to 45 MMboe.
The well did not reach its secondary target, Sabina, so a new well will likely be drilled later in the year (Wintershall Dea operates the license).
Drilling will start shortly of two approved infill wells in the Skarv area followed by production in the fourth quarter.
For the Skarv Satellite Project, all three subsea templates have been installed, pipelay operations have begun, and a turret local equipment room has been fitted aboard the Skarv FPSO. The Flotel Endurance is alongside the field center where it will support upcoming topside modifications.
