STAVANGER, NorwayStatoil has submitted a plan for development and operation (PDO) for the Trestakk field on the Halten Bank in the Norwegian Sea.

Trestakk, discovered in 1986, contains around 76 MMboe recoverable, mainly oil. Production will be tied back to the Åsgard A FPSO, with start-up anticipated in 2019.

Torger Rød, Statoil’s head of project development, said: “By rethinking our concept along with license partners and suppliers, we have arrived at a solution that costs almost 50% than the original concept. At the same time, we have been able to increase the recoverable resources significantly.”

Initial investment estimates of around NOK10 billion ($1.22 billion) have come down to NOK5.5 billion ($0.67 billion), following various improvements and concept adaptations.  

Development calls for installation of a subsea template structure with three production wells and two gas injectors.

Trestakk should ensure operations at Åsgard A extend toward 2030, added Siri Espedal Kindem, senior vice president for operations North in Statoil.

In the North Sea, Statoil has agreed to acquire Wintershall Norge’s 25% interest in the Byrding project, lifting its overall operated interest to 70%.

Byrding (PL090B) is an oil and gas discovery in the northern Norwegian North Sea which will be developed as a tie-in to the Troll field facilities. Recoverable reserves are estimated at 11 MMboe.

Statoil submitted a PDO in August with an estimated cost of NOK1 billion ($0.12 billion). The field is due to come onstream in 3Q 2017.
