The electrification of Gina Krog was part of an overall decision that phase two of the Johan Sverdrup development, in addition to electrification of the Johan Sverdrup field itself, also should include solutions for Gina Krog, Edvard Grieg and Ivar Aasen, and partial operation with power from shore for Sleipner.
Oil production on Gina Krog is declining, and to keep the production as high as possible, gas lift is used in some of the wells. In addition, two injection wells have been converted to producers. The strategy is to keep the gas production at plateau while at the same time maximising oil production. The second drilling campaign on Gina Krog started in June 2023 with two new wells, one with an exploration target. A PDO for the subsea tie-back of the discovery 15/5-2 Eirin was delivered in September 2023. The alternative oil export solution, which includes a pipeline from Gina Krog to the Sleipner A platform, is planned to be in operation in 2024.*
In 2020, Aivel were awarded the EPCIC contract (Engineering, Procurement, Construction, Installation and Completion) for electrification of Gina Krog, as a part of the overall area solution for the Utsira High.
The assignment involved carrying out modifications to prepare Gina Krog for operation with environmental-friendly electricity from the onshore power plant at Haugsneset.
