Hard-to-recover reserves of gas, liquid petroleum hydrocarbons, bituminous components, rare, rare-earth and noble metals of the gas-saturated part of oil and gas condensate and gas condensate fields at the late stage of development

Abstract

Many oil and gas condensate and gas condensate fields discovered in the ‘60s and ‘70s of the last century are now at the late stage of development. Research of the Laboratory for Hard-to-Recover Hydrocarbon Reserves of the Oil and Gas Research Institute of the Russian Academy of Sciences has been devoted to justify an increase in the resource potential and attain a maximum of recovery efficiency for long-developed fields using the evidence from the Orenburg and the Vuktyl oil and gas condensate fields. The involvement of the unique reserves of hard-to-recover oil will help to enhance declining production in old oil and gas producing regions.
