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 leading oil bearing objects of the fields of West Siberian group belong to Neocomian and Malm deposits.
The discovery potential of new oil and gas accumulations 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 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 due to the increase in volume and quality of seismic works 3D.
2. Increase in volume of prospecting and exploration drilling on the basis of seismic survey and analysis of the earlier received information.
3. To evaluate and mark out best promising new fields for purchase.
4. To continue exploration prospecting survey within the bounds of the existing license areas of “RusNeft”.
5. Guarantee of the annual performance of the resource base of the Company due to the geological exploration.
RESOURCES
In spring 2007 ÎÀÎ Oil and Gas Company «RussNeft» finished calculation and independent audit of oil and gas capacity as of 01.01.2007.
According to audited returns of Miller and Lents Company (USA), estimated reserves of hydrocarbons as of 01.01.2007 amount to 1255,1 mln. bbl. of oil equivalent, including 1092,1 mln. bbl. of oil and 978,4 bln. cubic feet of gas.
Estimates of oil and gas reserves are carried out in accordance with the requirements of the Society of Petroleum Engineers (US SPE) and World Petroleum Congress (WPC).
