Operations Update

23 September 2013 Cadogan Petroleum plc ("Cadogan" or "the Company") Cadogan Operations Update Following the Company's announcement on 16 July 2013 regarding operations at Borynya 3, the new logs run in the upper part of the well-site have confirmed the presence of gas and condensates and porosity in the range of 10% to 15%. Some difficulties and delays were caused by unexpected bottom hole assembly failure causing brine bleeding which inhibited the use of pressure measurement for more accurate test interpretation. Two intervals have been tested so far, 2745-2685m and 2935-2890m. In each case testing resulted in a flow of gas and condensate that was consistent but non-sustainable; as condensate increased, the gas decreased and after approximately 48 hours, all gas and condensate flow ceased. Gas was flared and liquid hydrocarbons were collected for analysis. Hydrocarbons were confirmed as oil (30 API) and condensate (48 API). Pressure build-up and reservoir characterization were however hampered by the leakage of brine in each interval tested. Further testing in the upper interval has begun, utilising a simpler string to re-shoot those layers with best porosity as identified by logs. This process will include an acid wash to improve flow and reduce formation surface damage. The Company expects to be able to announce the results from this further testing within a few weeks. Due to the clear presence of hydrocarbons, planned operations for information gathering on the production potential and assessment of future operations will continue. Due to the presence and nature of fluids and the petro-physical characteristics of the formation itself, the Company anticipates the need for a future acid-frac in order to obtain and support sustainable and commercial production at Borynya 3. Entry of the deeper intervals, down to circa 4,300m, is planned for 2014 with a suitable rig for such a heavy work-over. An anticipated acid-frac will also be planned during those operations.
