Antrim Energy Inc. has commenced drilling on schedule at the first of three planned wells near its August 2006 East Causeway discovery (Antrim 65.5%) in the UK North Sea.

The 2006 discovery tested a combined flow rate of 14,500 barrels of light oil per day with no water.

This first drilling operation is expected to take approximately 30 - 40 days. This first well will be drilled approximately two miles southwest of the East Causeway Discovery to an estimated depth of 3,735 metres (12,250 ft).

The drilling program will also assist in the evaluation of tie-in options for production to nearby facilities. Antrim has contracted AGR Peak Well Management of Aberdeen and the Transocean Prospect semi-submersible drilling rig for these wells.
