The Norwegian Petroleum Directorate reported a gas and oil discovery by Engie E&P Norge AS some 6 km northeast of Gjoa field.

Well 36/7-4, referred to as Cara, was drilled by the Transocean Arctic semisubmersible in 349 m of water. It encountered a 50-m gas column and a 60-m oil column in the Agat formation. NPD said reservoir quality ranges from “very good” in the top section to “good” in the lower section.

NPD said the well was formation tested and the maximum production rate was 1.3 million cu m/day through a 76/64-in. nozzle opening with “very good” production and flow properties. Extensive data and samples were collected, NPD said. Engie cited wireline logging and three successful core runs.

The well was drilled to a vertical depth of 2,702 m subsea, and was terminated in the Asgard formation in the Lower Cretaceous.

The licensees will consider a tie-in to existing infrastructure in Gjoa field (OGJ Online, Nov. 8, 2010).

Engie has 30% as does Idemitsu Petroleum Norge. Tullow Oil Norge AS has 20% as does Wellesley Petroleum AS.

Well 36/74 is the first exploration well in PL 636, which was awarded in APA 2011.
