ABSTRACT:
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 include 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.
