Padre Island Drilling Update

Wilson

   •The Kindee ST 212 #1 well on the Wilson Structure was spudded on 7
    February 2007 (Texas, USA).
   •The well is at 9,101 feet and drilling ahead. The planned total depth of
    the well is 12,400 feet (measured depth).
   •Wilson is the second in a multi-well programme. It is targeting a shallow
    prospect in the Upper Frio system. Similar prospects have been found to be
    productive elsewhere on Padre Island.
   •Gross best estimate potential reserves (previously described as 'P50
    potential reserves') for Wilson have been assessed at 9 billion cubic feet.
   •The well should reach total depth by end March on a trouble-free basis.

Plum Deep

   •Testing of Plum Deep's shallow zone, located behind the 7-inch liner,
    will be initiated once the results of the Wilson well are known. If testing
    is required on Wilson, the same rig would be used on both wells. This would
    deliver cost savings.
   •Core analysis results have now been received. These confirm that the
    sands in the deep section of Plum Deep have very low permeability. This is
    due primarily to the presence of calcite cement. For Plum Deep, this means
    that the deep reservoirs sampled are non-prospective.
   •Pantheon has a 25% working interest in Plum Deep
