Antrim to Case Second Well on the Central Causeway Trend, UK North Sea

CALGARY, ALBERTA--(Marketwire - Aug. 13, 2007) -


Antrim Energy (TSX:AEN) (AIM:AEY) has completed drilling the Antrim-operated Central Causeway well (Antrim 65.5%) in the UK North Sea. The 211/22a-7A well will be cased for future production.

The well was drilled directionally as planned to 11,960 ft (3,645m) to test the Jurassic Brent sandstones in the Central Causeway fault compartment approximately one kilometre southwest of the 211/22a-6 discovery announced last month, which tested a combined flow rate of 6,300 barrels of light oil per day from an 80 ft interval perforated in the Ness and Etive formations.

The 22a-7A well intersected a gross oil column of 203 ft in the Tarbert and Ness formations. A net pay thickness of 50 ft in very permeable sandstones with average porosity of 19 per cent is estimated from the electric log data and a series of MDT tests. These 22a-7A potential reservoirs are more permeable but otherwise are very similar to the reservoirs encountered in 22a-6 which intersected a gross oil column of 233 ft and a net pay interval of 105 ft with average porosity of 19%.

The oil column intersected in the Tarbert formation in 22a-7A was not encountered in the previous 22a-6 well. Although not definitive, the underlying Etive Formation appears to be water bearing in 22a-7A.

Antrim and its joint venture partners have elected not to production test the 22a-7A well, which would be confidently expected to test similar rates as achieved from the previous 22a-6 tests, and instead case the 22a-7A well for future production and immediately start drilling the third well in the program.

The third well in Antrim's three-well Causeway program will target the Ness sandstone on the southwestern flank of the Causeway structure. The well is designed to appraise the 211/22a-3 discovery made in 1984, which tested up to 5,500 barrels of oil per day from the Ness sandstone. The 22a-8 well is expected to start drilling later this week and will take approximately 35 days to drill.
