Sound Oil Updates Citarum PSC Operations in Indonesia

Sound has been advised by the operator of Citarum PSC that the drilling programme of three exploration commitment wells originally planned to start in March 2011 will not commence until the third quarter of 2011. In spite of this delay Sound is confident that the wells will be drilled within the extended first exploration period of the PSC.

Commenting on this situation Gerry Orbell, Chairman and CEO said:

"Although there will be a short delay we are very much looking forward to these Citarum wells. They will explore significant prospective resources in a new play in a well- established area of oil and gas production."

Sound Oil plc is a 20% shareholder (through its wholly owned subsidiary Mitra Energia Citarum Limited) in the Citarum PSC.
