Antrim Energy Says Clachnaben Well a Duster

Antrim has been informed by Dana Petroleum (E&P) Ltd. (Operator) that drilling operations have been concluded on the Clachnaben well, Block 211/22a in the UK North Sea. Interpretation of the data received to-date indicates that hydrocarbons are not present in commercial quantities. Antrim has agreed with the operator that the well should be plugged and abandoned. As reported in March 2005, Antrim farmed out its interest in this well to Dana in return for a minority interest in the license.

The Clachnaben drilling result does not reduce the prospectivity of Antrim's nearby Causeway prospect, in which Antrim holds a majority interest.

Antrim's third well in its 2005 North Sea drilling program, "Bennachie" operated by Nexen Petroleum U.K. Limited, is currently drilling in Block 21/15a.
