Aker BP submits PDO for Trell, Trine offshore Norway
Aker BP submitted a plan for development and operation (PDO) for Trell & Trine field to the Ministry of Petroleum and Energy.
The PDO is the third submission in the Alvheim area of the North Sea in 1 year, following those of Frosk and Kobra East & Gekko, the company said in a release Aug. 10. Trell and Trine discoveries lie 24 km east of the Alvheim FPSO in production licenses 102 F/G, and 036E/F, respectively.
Trell & Trine development is planned with three wells and two new subsea installations (manifolds) to be tied back to existing infrastructure on East Kameleon and further on to the Alvheim FPSO. One of the three wells is Trell Nord, which although not yet proven, has a high likelihood of discovery, the operator said. When the Trell production well is drilled, the plan is to first prove hydrocarbons in Trell Nord, then drill the wells in Trell and Trine. The program will conclude with the production well in Trell Nord, the company continued.
A contract has been awarded to Subsea 7 SA for field development. Work scope includes engineering, procurement, construction, and installation (EPCI) of the pipelines, spools, protection covers, and tie-ins using vessels from Subsea 7. The production pipeline is a pipe-in-pipe design.
Project management and engineering will begin immediately at Subsea 7’s offices in Stavanger, Norway. Fabrication of the pipelines will take place at Subsea 7’s spoolbase at Vigra, Norway, and offshore operations are expected to take place in 2023 and 2024.
Subsea 7 values the contract at $50-150 million.
Total investment from Aker BP for the development is estimated at $700 million. Production start is expected in first-quarter 2025.
Recoverable resources in Trell & Trine are estimated to be 25 MMboe. When Trell and Trine are approved, the Alvheim area is expected to surpass 750 million bbl either produced or sanctioned for development, according to Aker BP.
Aker BP is operator. License partners are Petoro and LOTOS Exploration & Production Norge.
