Abstract

Cette invention concerne un procédé d'exploitation de gisements de gaz et de pétrole et d'accroissement du taux d'extraction de gaz et de pétrole. Ce procédé consiste à disposer des électrodes dans les puits qui ont été forés sur le gisement, à sceller hermétiquement les puits à l'aide de packers, et à envoyer à ces électrodes un courant alternatif, continu ou par impulsions à haute tension. Ce procédé se caractérise en ce que les puits sont scellés hermétiquement à l'aide de packers au niveau du toit de la couche productive. Après l'envoi du courant électrique, on ajuste les paramètres de courant et de tension et/ou la disposition des électrodes les unes par rapport aux autres, ceci de manière à former un arc électrique entre les électrodes disposées dans un ou plusieurs puits ou, encore, entre des électrodes disposées dans deux puits voisins.
