Drilling Report

Sterling Energy PLC 16 December 2003 The board of Sterling Energy plc would like to bring to shareholders' attention the following announcement posted this morning by Fusion Oil & Gas plc: 'Operational Update The following statement relates to operational developments. Woodside Mauritania Pty Ltd, Operator of the Mauritania Area B Joint Venture, reported earlier today 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 metres overlying a gross oil column of approximately 122 metres. 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 establish connectivity and the net to gross of the reservoir section. Since reporting on the well on 9 December 2003, the 36 inch conductor was jetted to 1,423 metres, 18 inch hole was drilled to 2,127 metres, 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 metres. The well will now be plugged and abandoned, as planned.'
