About the field

WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE

Development: Edda is a field in the southern part of the Norwegian sector in the North Sea, 12 kilometres southwest of the Ekofisk field. The water depth is 70 metres. Edda was discovered in 1972, and the plan for development and operation (PDO) was approved in 1975. The field was developed with a manned wellhead and production facility and started production in 1979.
Reservoir: Edda produced oil from Maastrichtian and lower Paleocene chalk. The main reservoir is in the Upper Cretaceous Tor Formation, at a depth of 3100 metres.
Recovery strategy: The field was produced with pressure depletion. Starting in 1988, gas from the Tommeliten Gamma field was transported to Edda and used for gas lift in the wells.
Transport: The well stream was sent via pipeline to the Ekofisk Complex for export.
Status: Edda was shut down in 1998, and the facility was removed in 2012.
