ABERDEEN, UK --Oilexco has decided to drillstem test its recent Huntington oil discovery in UK central North Sea block 22/14b.
Well 22/14b-5 was drilled to a total depth of 13,325-ft (4,061 m). Wireline evaluation of the Upper Jurassic Fulmar sand at 12,750 ft (3,886 m) subsurface suggests the entire 130 ft (39.62 m) of Fulmar sand is oil-bearing, and wireline pressure and sampling across this interval has recovered 40° crude.
Oilexco plans a DST through 101 ft (31 m) of perforations, with test operations likely to be concluded within 10 days. The next step will be a further DST in the Palaeocene Forties interval. Both tests should provide useful data for pre-evaluation of two analogous Palaeocene structures identified on block 22/13 b to the west, which Oilexco also operates.
This fall, the company expects to employ one of its two semisubmersible rigs on long-term contracts for appraisal drilling on Huntington. Analysts Merrill Lynch believes Huntington may contain 150 MMbbl of oil, making it one of the UK's largest oil discoveries of recent times.
