Development

Tommeliten Gamma is a field in the southern part of the Norwegian sector in the North Sea, 12 kilometres west of the Edda field in the Ekofisk area. The water depth is 75 metres. Tommeliten Gamma was discovered in 1978, and the plan for development and operation (PDO) was approved in 1986. The field was developed with a subsea template including six production wells. The production started in 1988.

Reservoir

Tommeliten Gamma produced gas and condensate from fractured chalk of Late Cretaceous age in the Tor Formation and of early Paleocene age in the Ekofisk Formation. The reservoir is at a depth of 3500 metres.

Recovery strategy

The field was produced by pressure depletion.

Transport

The well stream was sent via pipeline to the Edda field for first-stage separation, then to the Ekofisk Complex and further through Norpipe to Emden in Germany and Teesside in the UK. Some of the gas was used for gas lift on the Edda field.

Status

Tommeliten Gamma was shut down in 1998, and the subsea template was removed in 2001. The field is currently being evaluated for redevelopment in combination with other decommissioned fields in the area.
