Wellesley Petroleum discovers hydrocarbons offshore Norway

Wellesley Petroleum AS has discovered gas and condensate in the Carmen prospect in Norwegian North Sea license PL1148, partner DNO ASA said in a release July 10.

Preliminary evaluation of comprehensive data, including cores and fluid samples, acquired from the discovery well and a follow-on extended sidetrack indicates gross recoverable resources in the range of 120-230 MMboe on a P90-P10 basis, DNO said. At the midpoint of 175 MMboe, the discovery is potentially the largest on the Norwegian Continental Shelf since 2013.

The two wells have established a deeper hydrocarbon-water contact, tripling the mid-point of DNO’s pre-drill expected range.

Carmen, a Middle to Lower Jurassic structural trap, was de-risked by Toppand  (wells 35/7-10 S & 35/7-10 A) and Røver Nord (PL923B, Wellesley 20%) discoveries, and lies in the Troll-Gjøa area close to both Kvitebjørn and FANTA area development infrastructure.

Wellesley operates the license with 50% interest. Partners are DNO (30%), Equinor Energy AS (10%), and Aker BP ASA (10%).
