Northern Russia-focused oil producer Exillon Energy has seen total proved (1P) recoverable reserves increase by 12% in the eleven months ended November 1st.

1P reserves stood at 125m barrels (mmbbls) at the end of the period, compared with 112 mmbbls at December 31st 2010 (end of Exillon's fiscal year), helped by the strong increase within the licence in West Siberia, where the group operates as Exillon WS.
