Statoil Presents Trestakk Development Plan
Statoil has submitted a Plan for Development and Operation (PDO) of the Trestakk discovery on the Halten Bank to the minister for petroleum and energy, Tord Lien, in Bodø.
The discovery, made in 1986, contains about 76 million barrels of recoverable oil equivalent, mainly oil. The project will be tied back to the Åsgard A oil production vessel, with planned production startup anticipated in 2019, Statoil informed.
“Trestakk is a good example of what is possible to achieve through spending time on working toward the best concept selection. By rethinking our concept along with license partners and suppliers, we have arrived at a solution that costs almost 50 percent less than the original concept. At the same time, we have been able to increase the recoverable resources significantly,” said Torger Rød, head of project development in Statoil.
The first investment estimates were around NOK 10 billion, which was reduced to NOK 7 billion when the concept selection was made in January 2016.
Additional improvements and concept adaptations this year further reduced the estimates to about NOK 5.5 billion, Statoil explained.
The concept selection 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.
“Volumes from Trestakk are an important contributor to ensure that operations on the Åsgard A production ship are extended toward 2030 and that more of the original volumes from the Åsgard field can be extracted,” said Siri Espedal Kindem, senior vice president for operations North in Statoil.
