Woodside Sees Excellent Results from Tiof West Well

Woodside

Woodside Mauritania Pty Ltd, Operator of the Mauritania Area B Joint Venture, reports that a preliminary evaluation of wireline logs and pressure data acquired from the Chinguetti-4-7 (Tiof West) step-out exploration well indicates a gas column of approximately 4 meters overlying a gross oil column of approximately 122 meters. Water bearing sands have been confirmed below the hydrocarbon bearing interval.

The top of the hydrocarbon bearing interval was intersected down-dip from the top of the hydrocarbon bearing interval in the Chinguetti-4-6 (Tiof) discovery well. Preliminary analysis of the pressure data indicates that the oil column is likely to be in direct pressure communication with the oil column intersected in the Chinguetti-4-6 (Tiof) well.

Further appraisal drilling will be required to assess the significance of the two wells and to verify connectivity and the net to gross of the reservoir section.

Since December 9, 2003, the 36 inch conductor was jetted to 1,423 meters, 18 inch hole was drilled to 2,127 meters, 13-3/8 inch casing was run and cemented and 12-1/4 inch hole was drilled to the final total depth of 2,991 meters.

The well will now be plugged and abandoned, as planned.
