STOCKHOLM, Sweden – Drilling activity is ramping up around the Edvard Grieg field in the Norwegian North Sea.
In January the jackup Rowan Viking started a three-well infill campaign on Grieg. According to operator Lundin Energy, two of the wells will be equipped with ‘Fishbones’ completions to improve productivity from the conglomeratic reservoir.
The first of these wells, already completed, should come onstream during the current quarter.
Lundin’s Rolvsnes extended well test (EWT) project involves a 3-km (2-mi) subsea tieback of the existing Rolvsnes horizontal well to the Grieg platform. The EWT will provide reservoir data to support a decision on the full-field development.
Earlier this month the semisubmersible West Bollsta started completion activities on the existing Rolvsnes well. First oil should follow this summer.
Solveig Phase 1, the first subsea tieback development to Grieg, is designed to keep the platform on plateau production until the end of 2023. Phase 1 reserves of 57 MMboe will be developed via three oil producer and two water injector wells.
Development drilling is due to start shortly, with first oil planned in 3Q. Installation of the subsea facilities and flowlines is currently over 95% complete.
Last year abandonment operations finished on the four Brynhild subsea wells in the North Sea, and the subsea facilities are due to be removed in the current quarter.
Lundin expects to start decommissioning of its Gaupe field, which ceased production in 2018, in 2023.
