Sep 24, 2007 - 07:00 ET Antrim Announces Successful Test Results From Causeway

CALGARY, ALBERTA and LONDON, UNITED KINGDOM--(Marketwire - Sept. 24, 2007) - 


Antrim Energy Inc. (TSX:AEN) (AIM:AEY) ("Antrim"), an international oil and gas exploration and production company, today announced successful test results from the Antrim-operated Causeway well 211/22a-8 (Antrim 65.5%) in the UK North Sea.

The 22a-8 well was drilled into the southwestern fault compartment to a depth of 12,830ft (3,910m), structurally the lowest penetration in the current program and close to the edge of the Causeway Field. It intersected a pay section similar to that encountered in the previously drilled 211/22a-3 well (1984), which tested up to 5,500 bopd from the Jurassic Ness Formation.

The 22a-8 was drilled approximately 1.4 km northeast of the 22a-3 location and encountered the Ness pay zone at a structural elevation 25ft (8m) higher than at 22a-3. The Ness sandstones were perforated over a 20 ft interval and flowed at rates of oil up to 1,180 bopd at 31 degree API with no water.

Electric log and test data indicate that the 22a-8 well has intersected a permeable Ness sandstone oil pay in a 98ft interval between 10,975 ft - 11,068 ft (3,344 - 3,374 m) true vertical depth.

The fourth and final well in Antrim's 2007 multi-well Causeway program is expected to start drilling within a week and will take approximately 35 days. The well will target the Brent sandstone sequence in the Central Causeway compartment which has been successfully drilled by 211/22a-7A and drilled and tested up to 6,300 bopd by 211/22a-6.

The non-operated well "East Kerloch" (Block 211/22a NW, Antrim 21%) is scheduled to start drilling in November 2007, approximately 10 km northwest of the Causeway trend.
