The concept selection for the Trestakk field consists of a template structure and an attached satellite well, which will be tied back to Åsgard A. Three production wells and two gas injection wells will be drilled for a total of five wells. (Image courtesy Statoil)
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.
