Equinor and its partners have made an oil and gas discovery in exploration well 30/6-C-2 A, named Lambda, in the Norwegian North Sea.

The exploration well is located in production licence 053, around 4km west of the Oseberg oil field in the northern part of the North Sea.

The Norwegian Petroleum Directorate (NPD) said that the discoveries have been made in two different formations, Eiriksson Formation and Cook Formation.

Following drilling from the Oseberg C integrated accommodation, processing and drilling platform to a vertical depth of 2,795m, well 30/6-C-2 A identified around 23m of oil and gas-filled sandstone with good reservoir quality in the Eiriksson Formation of the Statfjord Group.

The partners identified an estimated 15m of oil and gas-filled sandstone with moderate-to-good reservoir quality in the Cook formation.

The partners also encountered petroleum/water contact in the Eiriksson Formation, but not in the Cook Formation. The well was terminated in the Eiriksson Formation.

As per the preliminary estimates, the size of discovery in the Eiriksson Formation ranges between 0.2 and 0.4 million cubic metres (mcm) of recoverable oil equivalent.

The discovery’s size in the Cook Formation is between 0.2 and 1mcm of recoverable oil equivalent.

In a press statement, NPD said: “These discoveries represent important additional resources for Oseberg. Equinor and its partners will continue to work to improve understanding of the discovery and to identify production solutions for the oil and the gas.”

The well was not formation-tested. However, the partners carried out data collection.

Equinor operates production licence 053 with a 49.3% stake. The other licensees are Petoro (33.6%), TotalEnergies EP Norge (14.7%) and ConocoPhillips Skandinavia (2.4%).
