    摘要: The present invention relates to improved methods and compositions for sealing subterranean zones penetrated by well bores to reduce their permeabilities and increase their compressive strengths. The methods basically comprise the steps of introducing an aqueous sealing composition into a subterranean zone comprising a polymerizable monomer, a polymerization initiator, a hardenable epoxide containing liquid and a hardening agent, placing the sealing composition by way of the well bore into the subterranean zone and allowing the sealing composition to polymerize and harden whereby the well bore is sealed.

    摘要: The present invention provides methods of modifying the properties of a subterranean stratum penetrated by a well bore to increase the resistance of the stratum to shear failure. The methods basically include the steps of preparing a hardenable epoxy composition having flexibility upon hardening including an epoxide containing liquid or an epoxy resin and an epoxide containing liquid and a hardening agent. The epoxy composition is pumped into the subterranean stratum by way of the well bore and by way of the porosity of the stratum and then allowed to harden in the stratum.

    摘要: Polymeric well completion and remedial compositions which form highly pliable impermeable masses of desired rigidity and methods of using the compositions are provided. The compositions are basically comprised of water, a water soluble polymerizable monomer, a polymerization initiator and an oxygen scavenging agent. The composition is usually foamed and contains a gelling agent and a solid filler material to increase the density and/or rigidity of the impermeable mass formed.

    摘要: Polymeric well completion and remedial compositions which form highly pliable and durable impermeable masses of desired rigidity and methods of using the compositions are provided. The compositions are basically comprised of water, a water soluble polymerizable monomer, a polymerization initiator and an oxygen scavenging agent. The compositions are usually foamed and can contain a gelling agent and a solid filler material to increase the density and/or rigidity of the impermeable mass formed and/or a vulcanizable rubber latex, vulcanizing agent and vulcanizing activator to provide durability and other properties.
