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 14):
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, the method comprising the steps of:\n mixing an anhydrous sodium tetraborate and a fluid to create a crosslinker solution, wherein a concentration of anhydrous sodium tetraborate in the crosslinker solution is between 0.1% and 1.5% by volume; mixing a crosslinkable polyvinyl alcohol solution and a polyvinyl acetate solution to create a polymer solution, wherein a blend ratio of polyvinyl acetate to polyvinyl alcohol in the polymer solution is 45 to 1, wherein the polymer solution further comprises a carbohydrate, wherein the carbonhydrate comprises a starch, wherein a ratio of polyvinyl alcohol to starch is 2:1, wherein the carbohydrate further comprises a sugar, wherein the sugar comprises maltose,\n wherein the crosslinker solution and the polymer solution form the non-Newtonian combination, wherein a ratio of anhydrous sodium tetraborate to the crosslinkable polyvinyl alcohol in the non-Newtonian combination is between 1:3 and 1:5; \n delivering the non-Newtonian combination to a reaction zone in the wellbore, wherein delivering the non-Newtonian combination is configured such that the crosslinker solution is isolated from the polymer solution until the reaction zone, the reaction zone being defined as a point which allows the reaction between the crosslinker solution and the polymer solution to proceed to a completion time prior to reaching the alteration zone, the completion time being defined as the time to react substantially all of the crosslinker solution and the polymer solution, wherein delivering the non-Newtonian combination is configured to induce mixing of the polymer solution and the crosslinker solution,\n wherein a rate of dissolution of the polymer solution depends on the temperature in the reaction zone; \n 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, wherein 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.
