Abstract:
A method of modifying an alteration zone of a formation near a wellbore using a non-Newtonian polymeric composition created from a reaction of a non-Newtonian combination comprises the steps of mixing an anhydrous tetraborate and a fluid to create a crosslinker solution, mixing a crosslinkable polyvinyl alcohol and water to create a polymer solution, where the crosslinker solution and the polymer solution form the non-Newtonian combination, pumping the non-Newtonian combination to a reaction zone in the wellbore, where pumping the non-Newtonian combination is configured to induce mixing of the polymer solution and the crosslinker solution, allowing the non-Newtonian combination to react to form the non-Newtonian polymeric composition, allowing the non-Newtonian polymeric composition to migrate to the alteration zone, where the non-Newtonian polymeric composition migrates due to gravity, and allowing the non-Newtonian polymeric composition to interact with the alteration zone to modify the alteration zone.

Claim (Index 1):
A non-Newtonian combination for reacting to create a non-Newtonian polymeric composition in situ in a wellbore, the non-Newtonian combination comprising:\n a crosslinker solution operable to undergo a reaction to crosslink a crosslinkable polymer in the wellbore, the crosslinker solution comprising anhydrous sodium tetraborate and a drilling fluid,\n wherein the reaction is operable to proceed to a completion point; \n a polymer solution operable to form the non-Newtonian polymeric composition in the wellbore when brought into contact with the crosslinker solution, the polymer solution comprising the crosslinkable polymer and water, the crosslinkable polymer comprising polyvinyl alcohol and polyvinyl acetate.
