Development

Huldra is a field in the northern part of the North Sea, 16 kilometres west of the Veslefrikk field. The water depth is 125 metres. Huldra was discovered in 1982, and the plan for development and operation (PDO) was approved in 1999. The field was developed with a wellhead facility, including a simple process facility, and remotely operated from Veslefrikk B. Production started in 2001.

Reservoir

Huldra produced gas and condensate from sandstone of Middle Jurassic age in the Brent Group. The reservoir is in a rotated fault block at a depth of 3,500-3,900 metres, and initially had high pressure and high temperature (HPHT). There are many small faults in the field and two main segments without pressure communication.

Recovery strategy

The field was produced by pressure depletion and with low pressure production after 2007.

Transport

The wet gas was transported to the Heimdal field and the condensate to Veslefrikk for processing and export. The Huldrapipe to Heimdal is now being used by the Valemon field.

Status

Production ceased in 2014, and the facility was removed in 2019.
