Development

Gina Krog is a field on the Utsira High in the central part of the North Sea, just north of the Sleipner Vest field. The water depth is 120 metres. Gina Krog was discovered in 1978, and the plan for development and operation (PDO) was approved in 2013. The field is developed with a fixed platform with living quarters and processing facilities. Production started in 2017.

Reservoir

Gina Krog produces oil and gas from sandstone of Middle Jurassic age in the Hugin Formation. The reservoir is complex and compartmentalised with poor to moderate quality, and lies at a depth of 3,700 metres.

Recovery

The field is produced by gas injection. Gas is imported from Zeepipe 2A for gas injection and gas lift in the wells.

Transport

Wet gas is exported by pipeline to the Sleipner A facility and stabilised. Sales gas is exported from Sleipner A via Gassled (Area D) to the market, while unstable condensate is exported to the Kårstø terminal. Oil is transported to a floating storage and offloading vessel (Randgrid FSO), and then offloaded to shuttle tankers for further transport.

Status

The field is producing according to the plan. Maturation of new well targets is ongoing and drilling is expected to start in 2022. The facility will be supplied with power from shore starting in 2022, as part of the electrification of the Utsira High area. To reduce cost the Randgrid FSO will be replaced by a oil export pipeline between Gina Krog and Sleipner A platform in 2024.
