Wellbore treatment kits are provide that include a polymeric solution for placement in a wellbore that penetrates a subterranean formation and an activator for causing a polymer to precipitate out of the polymeric solution when it contacts the polymeric solution, wherein the resulting precipitate is capable of at least partially blocking a flow of a wellbore servicing fluid into the subterranean formation. The wellbore servicing fluid may be, for example, a drilling fluid, a cement composition, a workover fluid, or combinations thereof. The polymeric solution may comprise, for example, a poly vinyl pyrrolidone aqueous solution, and the activator may comprise, for example, a formate brine. When desirable, the precipitate may be easily and quickly removed from the subterranean formation by dissolving it in fresh water.
A wellbore treatment kit comprising:
A wellbore treatment kit comprising:
A subterranean well comprising a precipitate disposed therein for at least partially blocking a flow of a wellbore servicing fluid into a subterranean formation penetrated by the well.
A method of treating a wellbore that penetrates a subterranean formation, comprising:
A method of drilling a wellbore at least partially through a subterranean formation, comprising:
