Russian Reserves Update

PetroNeft Resources plc ('PetroNeft' or 'the Company'), owner and operator of Licence 61, Tomsk Oblast, Russian Federation, is pleased to provide an update on the approval of its reserves by Russian State Authorities.


  • Russian Reserves approved by the State Reserves Expertise Committee in Tyumen
  • Russian C1+C2 reserves are 74.8 million bbls
  • Reserves exceed SPE Reserves (2P 60.6 million bbls) as audited by Ryder Scott

Approved Russian Reserves

The Tyumen based West-Siberian branch of the Federal State Institution - State Reserves Committee have recently certified the Russian Reserves of LLC Stimul-T, PetroNeft's wholly owned subsidiary, as shown on the following table:




Bbls recoverable**

Lineynoye *  




























* Lineynoye and West Lineynoye fields are considered as one field by Russian Experts

** Conversion based on 43 degree API crude 


The approved reserves are based on PetroNeft's work program up to 31 December 2007 and do not include any reserves in respect of the recent discovery at Korchegskaya.  Russian C1+C2 reserves are calculated based on a different approach and are not directly comparable to SPE 2P reserves, but generally should be in alignment.  In PetroNeft's case the Russian reserves are based on a detailed reservoir simulation of the fields using modern modeling technology.

Dennis Francis, Chief Executive Officer of PetroNeft Resources plc commented:


"This is an important step in the Russian compliance process and in the path to bringing our fields to production in 2009. While there has been a lot of effort involved in the reserve calculation it has been a smooth process thanks to our Tomsk staff and local contractors."
