SYSTEM AND PROCEDURE FOR EXTRACTION OF OIL AND/OR GAS Russian patent published in 2011 - IPC E21B43/16 

FIELD: gas-and-oil producing industry.

SUBSTANCE: system consists of storage of carbon disulphide, of mechanism of discharge of at least part of carbon disulphide into reservoir, of mechanism generating pulsations in carbon disulphide and of water pressurising mechanism. Also, the said mechanism pressurises water into the reservoir after releasing carbon disulphide in it and after pulsations of carbon disulphide in the reservoir. The procedure consists in release of compound of carbon disulphide into the reservoir, in generation of pulsations in carbon disulphide in the reservoir and in pressurising water into the reservoir by means of the unit of water pressurisation upon release of carbon disulphide into the reservoir.

EFFECT: raised efficiency of procedure and reliability of systems operation.
