Antrim to Test First Central Causeway Well

Antrim Energy Inc. said that drilling has been completed on the Antrim-operated Central Causeway well (Antrim 65.5%) in the UK North Sea. The 211/22a-6 well will be cased in preparation for a testing program expected to commence later this week.

The well was drilled directionally as planned to 3,740 meters (12,260 ft), to test the Jurassic Brent sandstones in the Central Causeway fault compartment approximately 4 km southwest of Antrim's 2006 East Causeway 211/23d-17z oil discovery which tested 14,500 bopd from the Brent Tarbert and Ness sandstones.

As announced on May 14, 2007, the 22a-6 well is the first of three Antrim-operated wells planned for the Causeway area in 2007. An additional non-operated well 'East Kerloch' (Block 211/22a NW, Antrim 21%) is scheduled to start drilling in October 2007, approximately 10 km northwest of the Causeway trend.

The 22a-6 testing program is expected to take at least 14 days to complete.
