Gas and oil discovery northeast of the Gjøa field in the northern North Sea – 36/7-4 Cara

23. september 2016

Idemitsu has, together with our PL 636 license partners, successfully completed drilling and testing of the 36/7-4 Cara exploration well in the northern North Sea.

The Cara structure is located in the Norwegian North Sea, six kilometres northeast of the Gjøa field and 55 kilometres southwest of Florø. Water depth is 349 m. Well 36/7-4 is the first exploration well drilled in PL 636. The license was awarded as part of APA 2011.

The well was drilled to a vertical depth of 2,702 m below mean sea level, and encountered a 50 m thick gas column and an approximately 60 m thick oil column in the Lower Cretaceous Agat Formation. A successful formation test was carried out and recorded a maximum production rate of approximately 1.3 million Sm3 gas per day.

The provisionally estimated range of recoverable resources in the Cara discovery is 27-69 million standard barrels oil equivalents (Idemitsu's share is about 8-21 million standard barrels oil equivalents).

The partners will evaluate the possibility to tie the discovery back to existing infrastructure at the nearby Gjøa field.
The Cara discovery represents yet another discovery in one of Idemitsu’s two main core areas on Norwegian Continental Shelf, the northern North Sea and the southwestern Barents Sea.
“Idemitsu is satisfied to the see the successful completion of this important well in this prolific petroleum province”, says IdemitsuPetroleum Norge Managing Director Hiroshi Arikawa, who continues: “This represents an important addition to Idemitsu’s discovered resources that we are working eagerly to commercialise”.
In addition to its presence in the greater Snorre/Vigdis and the greater Fram and Knarr areas, Idemitsu enjoys an active presence in both the Wisting/Hanssen/Mercury PL 537 and PL 614 licenses, as well as in the PL 609 Alta discovery on the Loppa High, further south. In the latter area, Idemitsu received two new license awards in the 23rd licensing round.
Idemitsu Petroleum Norge AS has a 30 % share in PL 636. Joint venture partners are ENGIE E&P Norge AS (Operator, 30 %), Wellesley Petroleum AS (20 %) and Tullow Oil Norge AS (20 %).
