  • Methods for Servicing Well Bores with Hardenable Resin Compositions
    Publication number: 20100186956
    Abstract: Methods for servicing well bores with hardenable resin compositions are provided. In one embodiment, a method of servicing a well bore includes providing a hydrophobic well bore servicing composition comprising a liquid hardenable resin, a hardening agent, and a weighting material selected to impart a desired first density to the well bore servicing composition; introducing the well bore servicing composition into a well bore comprising a well bore fluid having a second density; allowing the well bore servicing composition to migrate through the well bore fluid to a desired location in the well bore based at least in part upon a difference between the first and second densities; and allowing the liquid hardenable resin to at least partially harden to form a well bore plug at the desired location in the well bore.
