When production began, recoverable reserves in this discovery were put at roughly 110 million barrels of oil. However, output so far is already more than double that figure.
The Tordis East and Borg structures have been tied back to the original development, with total reserves upgraded to about 360 million barrels.
According to operations vice president Arne Cock, Tordis stands out as one of the most successful developments on the Norwegian continental shelf.
"Shut-down was originally scheduled for 2006, but it's set to continue producing for many more years," he reports. "Production is still high, at almost 70,000 barrels per day."
He adds that operational regularity has been good. The recovery factor is currently 49 per cent, with a target of exceeding 50 per cent – very ambitious for a subsea development.
Tordis has been developed with seabed installations tied back to Gullfaks C. As part of production licence 089, it shares a joint operations organization with the Snorre field.
