Antrim Announces Causeway Drilling Success

Antrim Energy Inc. said that drilling has been completed on the Antrim-operated East Causeway well (Antrim 65.5%) in the U.K. North Sea. The 211/23d-17z well has been cased for production and a testing program is expected to commence later this week.

The well was drilled as planned both at a high angle and horizontally through the prospective zones to a measured depth of 14,900 ft (4,542 m), representing a true maximum vertical depth of 10,370 ft (3,161 m). Electric log and other well data received to date indicate that the 23d-17z well intersected approximately 1,185 ft (361 m) of net oil-bearing sandstone representing 57 ft (17.4 m) net vertical thickness of potential reservoir. Prospective reservoirs include the Jurassic Ness and Tarbert Formations drilled in two fault compartments. Several oil-bearing sandstone intervals were encountered, each interval demonstrating excellent reservoir quality on log analysis with an average porosity value of approximately 20%.

The 23d-17z testing program is expected to take at least 14 days.
