HOUSTON, July 25 -- Phillips Alaska Inc. and Anadarko Petroleum Corp. have found a satellite oil field near newly developed Alpine field on the North Slope of Alaska.
They estimate the Nanuq accumulation contains more than 40 million bbl of gross recoverable reserves, less than the Fiord satellite to Alpine, which may contain more than 50 million bbl.
The accumulation was discovered in April 2000 with the Nanuq-2 exploration well, which found 50 ft of vertical pay in a Cretaceous formation and 9 ft in the Kuparuk zone. A combined-zone production test flowed 1,750 b/d of 40°-gravity oil and 1.2 MMscfd of gas.
A delineation well, Nanuq CD1-229, was drilled from the Alpine drill site during the 2001 winter drilling season. It found 19 ft of vertical oil-bearing sand in the Cretaceous Nanuq reservoir. A production test flowed 460 b/d of 41°-gravity oil and 6.5 MMscfd of gas from a horizontal completion.
Production has been suspended. Phillips is evaluating further delineation and development of Nanuq field.
Phillips operates Alpine and its satellites with 78%. Anadarko owns 22%.
