And there is still a lot of oil left in the oil column on Troll. The two platforms, Troll B and Troll C, have available capacity for oil—and this might be of interest for surrounding licences. The development of the area north of Troll is particularly interesting.
With its stable oil and gas production, Troll is a significant contributor to our strategy to be able to deliver 2.5 million oil equivalents up to 2020.
"Now, the authorities are aware of the volumes present at Troll and want them to be recovered. We now assume a recovery rate of more than 50 per cent for the Troll oil, and that is high,” says Adolfsen. "Maybe we’ll have a Skrugard discovery again on Troll, or nearly 600 million barrels. There may be several pleasant surprises on Troll."
Adolfsen points out that since the beginning in 1995—1996, Troll has already joined the ranks of mature fields. With an ample growth in reserves and solid technical design, the field can produce until 2063.
"While we have been recovering the oil we have also made changes in facilities and infrastructure, including new living quarters on Troll A and ample updating and maintenance of Troll B and C,” he says. He particularly emphasises that Equinor has had solid support from its licence partners Shell, ConocoPhillips, Petoro and Total.
"We have been joined by the heavyweights on the Norwegian shelf in developing Troll. They have backed up the long-term perspective, joined in the commitment and challenged us in good and constructive dialogues. And when at the same time the authorities are a driving force for improved recovery, we have good reason to be satisfied,” says Adolfsen.
