New Badile CPR

Sound Oil, the European / Mediterranean focused upstream oil and gas company, is pleased to announce a significant upgrade in the Net Present Value of the Badile exploration gas prospect, onshore Po Valley, Italy.

ERC Equipoise Limited ("ERC") have completed a full independent Competent Person's Report ("CPR") of this prospect.

Badile is Sound Oil's 100% owned and operated exploration prospect, located some 45 km south-west of the geologically analogous "Malossa" gas field - which produced a total of 177 Bscf gas with associated light condensate.

The CPR has confirmed a Best estimate NPV10 of Euro 486 million, an increase of 60% on the previous CPR (which was Euro 302 million). The CPR has also identified a High Case NPV10 of Euro 1,745 million and a Low Case NPV10 of Euro 101 million.

Underpinning these estimates are gross prospective resources of 178bscf equivalent (106 Bscf of gas plus 12 MMbbl of condensate) with a High Case estimate of 673bscfe (397 Bscf of gas plus 46 MMbbl of condensate) and a Low Case estimate of 46bscfe (28 Bscf of gas plus 3 MMbbl of condensate). The study has also confirmed a 22% geological chance of success for the prospect.

James Parsons, Sound Oil's Chief Executive Officer, commented:

"Badile remains the largest and most strategic asset in Sound Oil's portfolio. We continue to prepare the Company for drilling this asset with a view to capturing the upside NPV, which now exceeds US$2 billion."
