Antrim Energy Inc. says 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."
