Oct 24, 2007 - 12:33 ET Antrim Completes 2007 Causeway Drilling Program

CALGARY, ALBERTA--(Marketwire - Oct. 24, 2007) - 


Antrim Energy Inc. (TSX:AEN) (AIM:AEY) ("Antrim"), an international oil and gas exploration and production company, today announced that the fourth and final well in its 2007 extended Causeway drilling program, has been successfully drilled and will be cased. As previously announced (30th August, 2007), the well, 211/22a-9, was drilled to provide pressure support to the future oil producers (22a-6 & 22a-7A) in the Central Causeway area.

The well was drilled to total depth 4,281 m (14,045 ft) and encountered sections of oil pay in the Ness and Etive formations despite being drilled at a significantly lower elevation (138 ft) than the producers. The pay sections have been confirmed by logging and an extensive program of fluid and pressure sampling by Modular Formation Dynamics Tester (MDT) tools which recovered light oil from the Ness sandstone. The structural elevation of these reservoir intervals, combined with the elevations identified in 22a-6 and 22a-7A, translate to a gross oil column of approximately 160 ft in the Central Causeway compartment.

"Pressure data obtained from sampling the Ness and Etive reservoir intervals in 22a-9 indicate that reservoir communication exists with the future producers drilled approximately 2.5 km to the south," said Stephen Greer, Chief Executive Officer of Antrim. "The 22a-9 result is a positive note on which to end the 2007 Causeway drilling program. With this latest well, an oil column has been proven to exist in the Ness and Etive formations significantly downdip from the previous discoveries and that injection into the Brent section encountered in this well is likely to support and maintain the expected high oil rates from the previously drilled production wells."

Review of the Causeway Drilling Program

The 22a-9 well completes the 2007 drilling program on Causeway. To-date four wells have been drilled and completed under the original budget for three drilled and completed wells. The significant cost savings are primarily attributed to Antrim's innovative well design and efficient management of the drilling program.

A summary of Antrim's 2006-2007 Causeway drilling program follows:

211/23d-17Z: tested 14,500 bopd from the Tarbert and Ness formations
211/22a-6: tested 6,300 bopd from the Ness and Etive formations
211/22a-7A: not tested but similar rates are expected to those measured
in 22a-6 (6000 - 7000 bopd)
211/22a-8: tested 1,180 bopd from the Ness Formation
211/22a-9: pressure support well for Central Causeway producers


In addition, other wells on Antrim's Causeway structure have tested 8,100 bopd (suspended in 1992) and 5,500 bopd (abandoned in 1984). Cumulative test rates from the structure now exceed 35,000 bopd with an expected additional 6000 - 7000 bopd from the untested 22a-7A well.

Further UK drilling:

Antrim's next step will be to submit a Field Development Plan (FDP) to the UK authorities, complete the Causeway development drilling in 2008 and start production facility construction on approval of the FDP, also expected in 2008. Another drilling program is scheduled for 2008 with at least one additional producer and a further two pressure support wells planned. A map detailing the Causeway drilling program to-date can be viewed attached to this press release on the company's website

In addition, Antrim expects to build on the current successful UK drilling program with the Northern North Sea non-operated Kerloch well (Antrim 21%) due to spud in November 2007. Kerloch is also a Brent oil prospect, similar to and immediately northwest of the Causeway property.

Antrim anticipates that drilling will also commence on the Fyne & Dandy property (Antrim 75% and operator) early in 2008. This is an appraisal drilling program designed to evaluate the extent of the oil accumulation associated with the undeveloped Fyne & Dandy oil fields in the Central North Sea.
