Field: YTTERGRYTA

General information

Current activity status: PRODUCING
Discovery wellbore: 6507/11-8
Discovery year: 2007

Description Norwegian

Development

The field is located in the Norwegian Sea, approximately 5 kilometres north of the Midgard deposit. The water depth in the area is about 300 metres. It has been developed with a subsea template tied to Midgard, and the gas is produced from one well.

Reservoir

The reservoir contains gas in Middle Jurassic sandstones of the Fangst Group and lies at a depth of 2 390 - 2 490 metres.

Recovery strategy

The field is produced by pressure depletion. The reserve estimate has been increased based on production data. It is assumed that gas which flows from the northern reservoir segment to the main segment during production is the reason for the good production results.

Transport

The gas is transported to the Midgard X-template and further to Åsgard B for processing. The gas from Yttergryta has a low CO2 content, making it suitable for dilution of CO2 in the Åsgard Transport System.

Status

The field came on stream in January 2009.
