LYSAKER, NorwayAker BP’s Subsea Alliance has completed the first offshore campaign for the 700-MMboe multi-field Yggdrasil development in the Norwegian North Sea.

The first subsea templates are nearing completion and should be ready for installation this summer.

Drilling is underway of a geopilot well at Frigg Gamma Delta, one of the discoveries involved in the project. The aim is to strengthen understanding of the reservoir, reduce risk and optimize the plan for startup and production.

In the Alvheim area of the North Sea, a recent exploration pilot well into the Trell North reservoir, part of the Tryving development, confirmed the anticipated volumes. The project’s three-well drilling campaign should conclude during the summer, which may allow startup earlier than planned in the fourth quarter.

Subsea tie-in should take place shortly of an infill well near Alvheim, with production expected in May. Aker BP has another infill target and expects to take an investment decision on this later in the year.

At the Tambar Field in the southern Norwegian North Sea, a new side-track well and completion of another producer well are both scheduled for late 2024.

The company is progressing its late-life strategy for the Ula Field, designed to secure safe and profitable operations until cessation of production in 2028. In parallel, work continues on the Ula decommissioning study to prepare a program of well plugging and platform removal.

Fabrication has started of the Valhall PWP Fenris platform utility module in Stavanger, the process module in Dubai, and the PWP jacket and Fenris topside in Verdal. Offshore modifications also are progressing for PWP, along with fabrication of the Fenris subsea pipelines in Norway and Scotland.

The offshore pre-lay survey and boulder removal campaign for Fenris was recently completed.

At the Equinor-operated Johan Sverdrup Field in the Utsira High region of the North Sea, drilling continues from both the field center and the Phase 2 subsea templates. Up to five new production wells should be drilled by mid-year, with a further five to come over the remainder of 2024, raising the total number of producers on Sverdrup to 41. 

During the fourth quarter, the field center drilling program will pause temporarily for maintenance on the drilling platform.

Finally, Aker BP expects to drill two new infill wells in the Skarv area in the Norwegian Sea in the second half of 2024. The Skarv Satellite Project is on track, with final testing and transportation achieved on three subsea templates, and the arrival of the Flotel Endurance. The flotel will be connected to the Skarv FPSO for eight months to accommodate the increased capacity needed for the project’s topside modifications. Fabrication of the manifold continues.
