Economic-geological aspects of putting into use a new Classification for crude oil and combustible gas reserves and expected resources
The article justifies criteria for grouping oil and gas reserves in the Classification by the economic efficiency of their development. It is suggested to supplement the reserve classification by commercial importance with a group of cost effective reserves and to distinguish a group technically recoverable reserves. Presented are the amounts of risk premiums to the basic discount rate taking into account the factors of geographical economic and geological risks. The form of the State Reserve Balance is proposed to be revised in order to provide for recording commercial reserves by the economic efficiency of their development. In connection with an inevitable increase in the balance, a part of the information on the geological-field description of reservoirs and fields should be entered in the Field Cadastre.
