GEOLOGY
Total amount of oilfields belonging to “RussNeft” is 178, among them 152 are under development at the moment.
The production enterprises of OAO Oil and Gas Company “RussNeft” are incorporated in four territorial-production groups:
1. West Siberian group
2. Ural group
3. Volga Region group
4. Central Siberian group
Territorial-production groups of enterprises of ÎÀÎ Oil and Gas Company "RussNeft"
Oil bearing capacity of the fields of Ural group and Volga Region group is due to terrigenous and carbonate rocks of Moscovian and Mississippian stages of Carbon and Devon.
The main oil bearing objects of the fields of West Siberian group belong to Neocomian and Malm deposits.
The discovery potential of new oil and gas deposits depends on the increase in volume and precision in carrying out of seismic exploration works 2D/3D and prospecting-exploration drilling both at formerly identified deposits, and regained ones.
In 2008-2009 increment of commercial reserves fully compensated the extraction; there was discovered Lusianinskoye oil-and–gas condensate field in Saratov region, revealed new deposits of oil and gas condensate within the limits of Tagrinskoye, and Roslavlskoye oilfields in KhMAO, Belokamennoye oilfield in Saratov region; at Verkhne-Shapshinskoye oilfield the boundaries of the earlier determined oil deposits are extended.
In the short term "RussNeft" is going to conduct the policy of geologic exploration, based on five principles:
 1. Further appraisal of the fields, being under development and in operation, mainly through additional deepening of operation wells and increase in volume and quality of seismic works 3D.
2. Increase in efficiency of prospecting and exploration drilling on the basis of seismic survey and analysis of the earlier received information.
3. Determination of potentially promising new subsurface areas on the basis pf geologic and economic evaluation for purchase.
4. Prospection and exploration of new oilfields and deposits within the boundaries of the existing license areas.
5. Guarantee of the annual performance of the resource base of the Company.
RESERVES
OAO NK “RussNeft” has available the results of evaluation and independent audit of oil and gas reserves as of 01.01. 2009
According to the data audited by Miller and Lents (USA) the oil and gas reserves of all the companies incorporated in OAO NK “RussNeft” as of 01.01.2009 equal:
Oil:
Recoverable reserves: 1 531.928 million barrels;
Supposed reserves: 669,686 million barrels;
Possible reserves: 983,917millionbarrels.
Gas:
Recoverable reserves: 858 246 million cubic feet;
Supposed reserves: 342 828 million cubic feet;
Possible reserves: 216 674 million cubic feet.
The evaluation of oil and gas reserves was performed in conformity with the new requirements of SPE/WPC/AAPG/SPEE (Society of Petroleum Engineers-US SPE , World Petroleum Congress - WPC and Society of Petroleum Evaluation Engineers - SPEE), enacted on 28.03.07.
