CA 2598438
The present invention relates to apparatus and methods to stimulate subterranean production an injection wells, such as oil and gas wells, utilizing rocket propellants. Rapid production of high pressure gas from controlled combustion of a propellant (3) , during initial ignition and subsequent combustion, together with proper positioning of the energy source in relation to geologic formations, can be used to establish and maintain increased formation porosity and flow conditions with respect to the pay zone .
La présente invention concerne un dispositif et des procédés permettant de stimuler la production souterraine de puits d'injection, tels que des puits de pétrole et de gaz, à l'aide de propergols. La production rapide d'un gaz haute pression par contrôle de la combustion d'un agent de propulsion, durant la phase d'allumage initiale et la phase de combustion consécutive, conjointement avec un positionnement adéquat de la source d'énergie par rapport à des formations géologiques, permettent d'établir et de maintenir une porosité et des conditions d'écoulement supérieures dans les formations par rapport à la couche rentable.
