Description Norwegian

Development

Gyda is an oil field located between Ula and Ekofisk in the southern part of the North Sea. The water depth in the area is 66metres. The field has been developed with a combined drilling, accommodation and processing facility with a steel jacket.

Reservoir

Gyda consists of three reservoir areas in Upper Jurassic sandstones of the Ula Formation. The reservoir depth is about 4 000metres.

Recovery strategy

The field produces with water injection as the drive mechanism for the main part of the field. Pressure support from thegas cap and the aquifer are drive mechanisms for other parts of the field.

Transport

The oil is transported to Ekofisk via the oil pipeline from Ula and further in Norpipe to Teesside. The gas is transported ina dedicated pipeline to Ekofisk for onward transport in Norpipe to Emden.

Status

Gyda is a mature field in tail phase and experiences increasing water production and challenges in maintaining the oil production. Work is ongoing to prolong the lifetime of the field. This includes further infill drilling and plans for installation of artificial lift in some wells. Gas lift has increased well production, and the gas lift capacity will be extended. Improved recovery by means of gas injection is being considered, including import of gas from potential external sources.
