ABERDEEN, UK – The semisubmersible Deepsea Bergen will P&A the 31/7-2S Brasse side track appraisal well in the license PL 740 in the Norwegian North Sea.

According to operatorFaroe Petroleum, the well was drilled to 2,275 m (7,464 ft) TVDSS, targeting the reservoir 1 km (0.6 mi) to the west of an appraisal well drilled in June and 2.4 km (1.5 mi) south of last summer’s discovery well.

It successfully penetrated the gas-oil contact and oil-water contact in the southern part of theBrasse field, encountering around 18 m (59 ft) of gross oil-bearing and 4 m (13 ft) of gross gas-bearing Jurassic reservoir above the oil-water contact. 

Early analysis suggests oil in a good-quality, sand-rich reservoir with the same oil-water contact as in the previous two wells, while pressure data indicates good pressure communication within the reservoir.

Based on the results, Faroe has upgraded recoverable resources to 46-76 MMbbl of oil and 59-97 bcf of dry gas.

Brasse is within tieback range of the Wintershall-operated Brage field platform and the Statoil-operated Oseberg field center.

The company has performed feasibility studies and commissioned external studies for the subsea production system, flow assurance and pipeline and marine work.

Its preliminary reservoir development plan includes three to six production wells with an optional water injector for pressure support. The reservoir should deliver at rates above 30,000 boe/d, with first oil anticipated in 2020/21.

Faroe estimates capex at around $550 million for a mid-case development scenario of four wells and one subsea template.

Final concept selection and submission of a plan for development and operations should follow during 2018.
