Engie E&P Norge and its PL636 (Cara) partners have discovered oil and gas in well 36/7-4 close to the Gjøa field in the North Sea's Norwegian region.

In water depths of 349m, the well was drilled by Transocean Arctic and proven oil and gas in Agat formation. It is expected to be in the range of four million to 11 million standard cubic meters of recoverable oil equivalent.

Drilled 6km north-east of the Gjøa field to a vertical depth of 2,702m below mean sea level, the Cara well reached final total depth in the Asgard formation of Lower Cretaceous.

Engie E&P Norge managing director Cedric Osterrieth said: “The discovery is situated in our core area in the North Sea, and confirms our view that even mature areas of the Norwegian Continental Shelf have an interesting exploration potential.

“Together with our licence partners, we will now evaluate the possibility to link the discovery to existing infrastructure at the nearby Gjøa field. This will reduce both time and costs concerning a future development.”

The semi-submersible floating production platform Gjøa is operated by Engie.

"It confirms our view that even mature areas of the Norwegian Continental Shelf have an interesting exploration potential."

The company has carried out data acquisition, including wireline logging and three successful core runs, which showed that the reservoir is of decent quality.

Engie subsurface head Raphaël Fillon said that the Cara discovery gives the company an increased understanding of the subsurface, while strengthening its view on other licences in the area.

Well 36/7-4 is in production licence 636, which was awarded in the Norwegian licensing round awards in predefined areas (APA) in 2011.

Engie operates the licence with a 30% interest, while other partners are Idemitsu Petroleum Norge (30%), Tullow Oil Norge (20%), and Wellesley Petroleum (20%).
