Sval has made a commercial oil and gas discovery in the Cerisa prospect in the northern part of the North Sea. The estimated size of the discovery is 18 to 39 million barrels of oil equivalent.

Jørgen Moe, VP Exploration at Sval Energi, said: “The discovery is a candidate to be developed and linked to nearby infrastructure, with the Gjøa platform as the natural host candidate. Our strategy of exploring for oil and gas in mature areas on the shelf is paying off.”

The Cerisa exploration well and three additional side-track appraisal wells were drilled by the semi-submersible drilling rig Deepsea Yantai, who also made the Ringhorne North discovery this spring. The oil-water contact was not encountered in the wells drilled, implying upside to the estimated resource range.

The Cerisa discovery is located 17 kilometers northeast of the Gjøa platform and five kilometers from the Duva subsea template. The Gjøa field is about 80 kilometers southwest of Florø.

Cerisa is located in Production License 636 and was awarded in the Awards in Predefined Areas (APA) licensing round in 2011. The license partners are Sval Energi (10%), Vår Energi (operator, 30%), PGNiG (30%) and INPEX Idemitsu (30%).
