Small oil pool proven west of Johan Sverdrup in North Sea
Statoil has completed its latest exploration well in the Johan Sverdrup area of the Norwegian North Sea.
The semisubmersibleOcean Vanguard drilled well 16/2-18S on license PL265, west of the main bounding fault for the Johan Sverdrup discovery. It intersected a 15-m (49-ft) oil zone with poor production characteristics, which was not in communication with the main field.
Lundin as operator of PL501 and Statoil as operator of PL265 are close to concluding their appraisal program having drilled 20 wells so far on the structure. They expect to announce a conceptual development decision and an updated resource estimate by the end of the year.
Front-end engineering will then be completed prior to submission of a final development plan by end-2014. By that point all parties in the licenses with working interests in the field will have agreed to a unitization process.
Lundin expects plateau production from Johan Sverdrup to exceed 500,000 b/d of oil, equivalent to more than 25% of current Norwegian oil output.
Elsewhere in the North Sea, Lundin discovered oil earlier this year with a well on theLuno II prospect in PL359 on the southwestern flank of the Utsira High, 15 km (9.3 mi) south of the Edvard Grieg field development.
The structure appears to span two separate reservoir segments, with gross contingent resources of 25-120 MMboe in the southern segment and a prospective 10-40 MMboe in the Luno II North segment.
Lundin plans follow-up drilling later this year or early in 2014 to further delineate the southern reservoir segment, which could extend east into the company’s operated PL410 license. Pressure data indicates that the petroleum system in Luno II is different to that encountered at Edvard Grieg and Johan Sverdrup.
Lundin expects first production from itsBrynhild development in the fall and peak at 12,000 boe/d. The jackup Maersk Guardian started work on the first development well in June. The Brynhild subsea template, manifolds, production and water injection pipelines are all in place.
Shell UK’sHaewene Brim FPSO, which will receive Brynhild’s crude, arrived at the dry dock in Scotland last month for topside modification and life extension work. Eventually four development wells will be tied back to the Shell-operated Pierce field infrastructure.
Finally, fabrication of subsea structures has started for the Marathon-operated Bøyla field, a 28-km (17.4-mi) subsea tieback to theAlvheim FPSO. Lundin is a partner in both. There will be two production wells and one water injector.
