CALGARY, Canada --Antrim Energy has had further success with its latest well on the Causeway oil discovery in UK North Sea block 211/22a.
The 211/22a-8 well was drilled into a south-western fault compartment to a depth of 12,830 ft (3,910 m), the deepest level of the current appraisal drilling program. The well intersected a pay section similar in size to the yield from the 211/22a-3 well of 1984, which tested up to 5,500 b/d from the Jurassic Ness formation.
The location of the latest well is 1.4 km (0.9 mi) northeast of 22a-3. The Ness sandstones were perforated over a 20-ft (6-m) interval, flowing up to 1,180 b/d of 31º API oil. Log and test data suggest the well has intersected a permeable Ness sandstone oil pay in a 98-ft (30-m) interval between a true vertical depth of 10,975 ft and 11,068-ft (3,345-3,374 m).
Antrim expects to spud the final well in this campaign next week, targeting the Brent sandstone sequence in the Central Causeway compartment that tested up to 6,300 b/d via well 211/22a-6. A well on East Kerloch, 10 km (6 mi) northwest of the Causeway trend, is expected to be under way in November.
