                                 Pasunda 1 well


Pasundan 1 well: drilling has been held up for 13 days by the continuing loss of
drilling fluid into the formation at the bottom of the well at 6769 feet. These
conditions are not unknown in the area but the loss of drilling time will add to
the duration and costs of this well. The Operator is continuing to try to cure
the problem and then run the 95/8 inch casing as determined by the drilling
programme.

Pasundan 1 is scheduled to drill to 10322 feet to encounter three separate
potential reservoir intervals at various depths.

Gerry Orbell said that although it is unfortunate that drilling has been
temporarily held up, it is nevertheless encouraging to have encountered
significant porosity in the well. Our forward operations will be tailored to
determine the nature of the original fluids contained in the rocks at this
level.

Sound Oil plc holds a 20% interest in the Citarum Production Sharing Contract
through its subsidiary Mitra Energia Limited.
