Trestakk is a 76-MMboe accumulation discovered in 1986. It will be tied into theÅsgard A production vessel, coming onstream in 2019.
Statoil and its partners, working with TechnipFMC, have brought down the cost by nearly 50% to NOK5.5 billion ($639 million) following varioussimplification measures and concept/scope adjustments. The partners also expect to recover much more oil than originally anticipated.
Development calls for a subsea template with three production wells and two gas injectors.
Siri Espedal Kindem, head of the operations north cluster at Statoil, said: “The Trestakk volumes are an important contributor in maintaining profitable operation of theÅsgard A vessel up to 2030. It also enables us to extract more of the original Åsgard field volumes.”
Trestakk is around 20 km (12.4 mi) south of the Åsgard field in around 300 m (984 ft) of water. The reservoir is at a depth of around 3,900 m (12,795 ft).
