The Trestakk field development plan covers a subsea template with four well slots and one satellite well. A total of five wells will be drilled: three for production and two for gas injection. Trestakk is tied back to the Åsgard A floating production vessel, which has been modified in 2018 to receive the production from Trestakk, extending the lifetime of the installation to 2031.
Thanks to careful planning with a focus on cost efficiency, Equinor Energy and its partners, ExxonMobil and Vår Energi, managed to save NOK 0.5bn from the original investment of NOK 5.5bn. At field start-up, the final costs are expected to be NOK 5 bn.
The Trestakk oil and gas field, contained in Block 6406/3 PL091 and discovered in 1986, holds estimated recoverable resources of 76 MMboe. The authorities approved the field development project in 2017.
An EPCI contract type was signed with TechnipFMC to provide all necessary installations.
