The present invention provides methods of modifying the properties of a subterranean stratum penetrated by a well bore to increase its strength and decrease its permeability. The methods basically comprise the steps of preparing a hardenable epoxy composition having flexibility upon hardening, pumping the epoxy composition into the subterranean stratum by way of the well bore and by way of the porosity of the stratum and then allowing the epoxy composition to harden in the stratum.
La présente invention porte sur des méthodes pour modifier les propriétés d'une strate souterraine pénétrée par un puits de forage dans le but d'augmenter sa résistance et de réduire sa perméabilité. Les méthodes comprennent essentiellement les étapes suivantes: préparer un composé époxydique durcissable doté de souplesse en durcissant, pomper le composé époxydique dans la strate souterraine en se servant du puits de forage et de la porosité de la strate et laisser durcir le composé époxydique dans la strate.
