Drilling Update

1 March 2013

1 March 2013 - Exillon Energy plc, a London Premium listed independent oil producer with assets in two oil-rich regions of Russia, Timan-Pechora ("Exillon TP") and West Siberia ("Exillon WS"), is pleased to announce a drilling update.

ETP V - 5001

Well ETP V - 5001 was spudded on 1(st) October 2012 and drilled and cemented in 126 days on the northern tip of the ETP V licence area. The well encountered Lower Silurian reservoir at 3,223 metres, confirming 22.8 metres of absolute effective net oil pay within the Silurian reservoir. In addition, the well encountered Domanic reservoir at 3,204 metres, confirming 3.8 metres of absolute effective net oil pay. Due to the angled trajectory of the well bore, this well exposed 29.2 metres of effective net oil pay for production.

The well is structurally elevated by 26 - 46 metres above known oil in the ETP V field, which supports the Group's assertion that this well may have discovered a new oil field that extends into the North ETP VII licence, also owned by the Group.

Upon perforation, the well flowed water-free oil to the surface with a flow rate of 729 bbl/day from the Silurian reservoir. Core results illustrate that the reservoir is represented by fractured vugous porosity dolomites.

The well was drilled 1.1 km to the north-east of Pad 5, and is now connected to existing production facilities. The drilling rig has now spudded Well ETP IV - 5002 targeting the northern part of the ETP IV field.

ETP IV - 3000

Well ETP IV - 3000 was spudded on 1(st) September 2012 and drilled and cemented in 105 days on the southern part of the ETP IV field. The well encountered the Lower Silurian reservoir at 3,262 metres, confirming 12.5 metres of absolute effective net oil pay within the Silurian reservoir. In addition, the well encountered Domanic reservoir at 3,237 metres, confirming 1.6 metres of absolute effective net oil pay. Due to the angled trajectory of the well bore, this well exposed 15.8 metres of effective net oil pay for production.

The well is currently flowing 567 bbl/day of fluid, of which 439 bbl/day is oil. The well is gradually increasing the oil flow rate as it cleans up the well bore from drilling mud and water used during completion.

The well was drilled 0.86 km south of Pad 1, and is now connected to our existing production facilities. Well logging and testing results support our geological understanding of the ETP IV field. This is the last well on the southern margin of the ETP IV field, and the drilling rig has now been demobilized.
