Output has been limited and below forecast, and water capacity constraints and uptime issues at the host FPSOHaewene Brim on the UK side of the median line have not been resolved.
It is therefore no longer economical to produce Brynhild, Lundin said. The company will work on a cessation plan for submission to the Norwegian Ministry of Petroleum and Energy for approval.
Elsewhere in the Norwegian North Sea, production from Lundin’s Edvard Grieg field has been higher than forecast due to strong production efficiency of 97%, and the jackupRowan Viking has drilled the final three planned development wells with results as expected or better than prognosis.
Production capacity from the 10 completed producer wells is currently more than double the facilities capacity contractually available for production from Edvard Grieg, and there has been no material water production to date.
Lundin plans to initiate a 4D seismic survey during the current quarter to support infill drilling planned for 2020.
At the nearby Ivar Aasen field, which exports its production to the Grieg complex, operator Aker BP has drilled two new water injector wells to improve pressure support to the eastern part of the field.
As for the Alvheim area, in which Lundin is also a partner, an infill well is currently drilling targeting the Kameleon area, and Aker BP has deferred a planned side track of an existing Volund well to 2019.
At theJohan Sverdrup Phase 1 complex, two accommodation units have been mobilized offshore with around 800 personnel engaged at present on hookup of the installed facilities.
Installation continues of the oil export pipeline and will be followed by laying of the gas export pipeline.
The remaining two steel jackets – one completed by the Kvaerner Verdal yard and another nearing completion at the Dragados yard in southern Spain – are both set to be installed in August.
Samsung in South Korea is still constructing the topsides for the process platform while work continues also on the living quarters platform topsides at Kvaerner Stord. Allseas’Pioneering Spirit is due to install both next spring.
To date eight Phase 1 production wells and 10 water injectors have been completed, Lundin said, with results as expected or better. Pre-drilling has finished ahead of schedule, allowing the remaining contracted rig time to be used to drill two additional water injectors later this year.
Tieback of the eight pre-drilled producer wells from the drilling platform should start during 4Q.
Lundin has also made changes to its 2018 exploration drilling schedule, and now plans to operate or participate in 11 wells targeting net unrisked resources of around 600 MMboe.
Drilling of the Korpfjell Deep prospect in the Barents Sea has been moved to 2019 due to later availability of the rig, while two follow-up wells in PL869, in the same area as the Frosk oil discovery in the North Sea, have been added to the line-up.
Aker BP discovered 30-60 MMboe with its first well on the Frosk prospect, northwest of the Bøyla field in the Alvheim area. The partners now plan two follow-up wells during 4Q on the Froskelår and Rumpetroll prospects in the adjacent PL869, followed by a production test well on Frosk next year, to be tied into the Bøyla subsea facilities.
Finally, Lundin has concluded a license swap with DNO to create an initial entry position into the Tampen/Horda Platform area of the North Sea.
It will receive a 10% interest in each of PL926 and PL929 and 15% in each of PL921 and PL924, giving DNO in exchange 10% stakes in PLs825, 767, 902 and 950.
Lundin has concluded another swap deal with Italy’s Edison in the southern Barents Sea, where it will gain a 10% interest in PL850. Edison receives 10% of PL952.
