    摘要: Properties of a subterranean stratum penetrated by a well bore are modified, for example to increase the resistance of the stratum to shear failure, by pumping a hardenable epoxy composition having flexibility upon hardening and comprising an epoxide-containing liquid or an epoxy resin and an epoxide-containing liquid and a hardening agent, into the subterranean stratum by way of the well bore and by way of the porosity of the stratum, and allowing it to harden in the stratum.
