Field: GJØA

General information

Current activity status:	PRODUCING
Discovery wellbore:	35/9-1 R
Discovery year:	1989
Discoveries included:	35/9-2 36/7-1

Description Norwegian

Development

Gjøa is located about 40 kilometres north of the Fram field. The water depth in the area is 360 metres. The development comprises five subsea templates tied to a semi-submersible production and processing facility. The Gjøa facility is supplied with power from shore.

Reservoir

The reservoir contains gas above a relatively thin oil zone in Jurassic sandstones in the Viking, Brent and Dunlin Groups. Thefield comprises several tilted fault segments with partly uncertain communication and varying reservoir quality. The reservoir depth is about 2 200 metres.

Recovery strategy

The reservoir is produced by pressure depletion.

Transport

Stabilised oil is exported in a pipeline connected to Troll Oljerør II, for further transport to Mongstad. Rich gas is exported in a pipeline to the Far North Liquids and Associated Gas System (FLAGS) transport system on the UK continental shelf, for further transport to St. Fergus

Status

Production started in November 2010.
