    摘要: Methods for treating a wellbore and compositions used for same are provided that include emplacing a polymer-forming composition in the wellbore, and initiating polymerization of the polymer-forming composition to form a polymerized material in the selected region of the wellbore. In some aspects, polymeric compositions provided may also be useful for isolating pressure differentials downhole.

    摘要: A spacer fluid made of a viscosity thinner, a weighting agent, an antifoaming agent, and a non-ionic surfactant in a base aqueous fluid. In some instances, the viscosity thinner is a sulfomethylated tannin, the weighting agent is barium sulfate, the antifoaming agent is a silicone, and the non-ionic surfactant is an ethoxylated alcohol. A method of treating a well bore annulus in preparation of introducing water-based cement slurry into a well bore using the spacer fluid. A method of using the spacer fluid to position a first fluid into a well bore annulus of a well bore containing a second fluid. A method for fluidly isolating at least a portion of a well bore annulus in a well bore containing an oil-based drilling fluid using water-based cement slurry and the spacer fluid.

    摘要: The present invention relates to moldable sand compositions, methods for making the moldable sand compositions, and methods for using the moldable sand compositions. In a particular embodiment, the moldable sand composition comprises between about 70% to about 95% sand, between about 5% to about 30% water, a polar polymeric resin, a crosslinking agent, and a humectant. In an exemplary embodiment, the composition contains no oils, waxes, glycols, or rubbers. The composition is capable of becoming hardened over time in order to maintain the achieved shape, and can be re-wetted and molded again after becoming hardened.
