Fossil Energy – Gas Discovery Norway
Wellesley Petroleum has made a significant gas and condensate discovery on the Carmen prospect in the Norwegian North Sea.
The discovery is said to be the largest one made on the Norwegian Continental Shelf since 2013.
The Carmen well (35/10-10 S) is located in PL1148, which is operated by Wellesley with DNO, Equinor, and Aker BP participating as partners. Carmen is located close to existing infrastructure with clear routes towards commercialisation. Other recent discoveries in the area are Røver Nord, Kveikje, Ofelia, Røver Sør, and Heisenberg.
Carmen is Wellesley’s first operated HPHT well. It was spud in early April and finished in June 2023 with the Odfjell Drilling-managed Deepsea Yantai semisub.
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 million barrels of oil equivalent (MMboe) on a P90-P10 basis. At 175 MMboe, the mid-point of this range, Carmen ranks as the largest discovery 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 is DNO’s sixth discovery in the Troll-Gjøa area since 2021 and is located close to existing infrastructure with clear routes towards commercialization. The other discoveries are Røver Nord, Kveikje, Ofelia, Røver Sør and Heisenberg.
