A drill stem test (DST) on the Brasse well in the Norwegian North Sea has shown high flow rates and excellent reservoir properties, says UK-based independent Faroe Petroleum.
The Brasse appraisal program will now continue with the drilling of a side-track well, targeting a location about 1000m west of the current main well bore, to map the reservoir distribution and further delineate the Brasse structure.
The Brasse discovery was made by Faroe in 2016 and within tie-back distance to existing infrastructure. It is 13km to the south of the Brage field platform, in which the company holds a 14.3% working interest and 13km to the south east of the Oseberg field center.
The DST on the 31/7-2 S Brasse appraisal well DST flowed at a constrained maximum stable rate of 6187 b/d of oil from a 3.6m perforated interval, through a 1in choke and with 800 psia at the wellhead. Flow and pressure measurements indicate a prolific reservoir, says Faroe.
Site sampling confirmed good quality light crude similar to the nearby Brage field (Faroe 14.3%), with 36.2° API oil with a gas/oil ratio of 887 scf/stb, to be confirmed by onshore laboratory testing.
Faroe operates the field with 50% equity together with Point Resources (50%).
