METHOD AND FACILITY FOR CONTROL OVER UNSTABLE STATE IN WELL BOREHOLE Russian patent published in 2009 - IPC E21B43/18 E21B43/117 

Abstract RU 2352769 C2

FIELD: mining.

SUBSTANCE: method of control over unstable state in well borehole wherein columns of firing gun are formed in accordance with required transitive unstable state in interval of perforation consists in creating required transitive unstable state in interval of well borehole perforation. There is used porous hard material produced by detonation of the column of the firing gun at direct vicinity from one section of firing gun column. Also porous hard material has originally pressurised volume to receive fluid mediums from the well borehole in result of detonation of the column of the firing gun.

EFFECT: upgraded communication of fluid medium between well and reservoirs in formations.
