Pasundan-1 well

Following press speculation in Malaysia earlier today, Sound Oil plc wishes to 
deny reports that an oil discovery has already been made at the Pasundan-1 
exploration well.  Drilling operations at Pasundan-1 are on schedule and the 
well is at 6,769 feet.

Sound Oil plc is a 20% shareholder (through its wholly owned subsidiary Mitra
Energia Citarum Limited) in the BPREC operating company that is drilling the
Pasundan-1 exploration well, located approximately 50 km southeast of Jakarta,
Java, Indonesia.
