ConocoPhillips Skandinavia, a Norwegian subsidiary of the U.S. energy giant, ConocoPhillips, has made a minor gas discovery in a well located southwest of the Skarv field in the Norwegian Sea.
ConocoPhillips received adrilling permitfor the well /4-3 S from the Norwegian authorities in April 2022. This well was drilled about 30 kilometres southwest of theSkarv field in the Norwegian Seaand about 240 kilometres west of Brønnøysund.
In an update on Thursday, the Norwegian Petroleum Directorate (NPD) informed that ConocoPhillips as the operator ofproductionlicence 1064, valid until 14 February 2026, has concluded the drilling of the wildcat well /4-3 S. This is thefirst exploration wellinthis production licence, which was awarded inAPA 2019.
ConocoPhillips Skandinavia has an ownership interest of 40 per cent interest in this licence while other licensees are PGNiG Upstream Norway with 30 per cent, Aker BP with 20 per cent, and the Norwegian state-owned giant Equinor, which holds the remaining 10 per cent interest.
The NPD explained that the objective of the well /4-3 S was to prove petroleum in reservoir rocks from the Late Cretaceous in the Lange Formation. During the drilling of the well, sandstone layers were encountered in the Lange Formation totalling about 55 metres with poor reservoir quality.
According to the NPD, the well encountered an approximately 1-metre gas column in the shallowest part of the sandstone layers, but no contacts could be proven.
The NPD pointed out that thepreliminary estimates indicate the size of the discovery is less than 0.1 million Sm3of recoverable oil equivalent. In light of this, the result from this well will be considered by the licensees for further prospectivity in the licence.
While the well was not formation-tested, extensive data acquisition and sampling were carried out, based on the NPD’s statement. In addition, the Norwegian Petroleum Directorate confirmed that the well was drilled to a vertical depth of 3914 metres below sea level, and was terminated in the Lange Formation from the Late Cretaceous.
Furthermore, the water depth at the site is 436 metres and the well will now be permanently plugged and abandoned. This well was drilled by Transocean’sTransocean Norgesemi-submersible rig, which was originally contracted in June 2021 forfour wells with five one-well options.
As disclosed by the NPD, the Transocean Norge rig will now drill wildcat well /3-2 S in production licence 935 in the Norwegian Sea, where ConocoPhillips Skandinavia is also the operator.
