Abstract

Methods and apparatus for using a fluid within a subterranean formation including forming a fluid comprising an oil-soluble resin acid and an organosilicon compound and introducing the fluid to the formation, wherein the relative permeability of the formation increases, and wherein the production of water is reduced more than if no fluid was introduced to the formation. Methods and apparatus for reducing water production within a subterranean formation including forming a fluid comprising an oil-soluble resin acid and an organosilicon compound and introducing the fluid to the formation, wherein the production of water is reduced more than if no fluid was introduced to the formation.

Claims

exact text as granted — not AI-modified
1 . A method of using a fluid within a subterranean formation, comprising:
 forming a fluid comprising an oil-soluble resin acid and an organosilicon compound; and   introducing the fluid to the formation;   wherein the relative permeability of the formation increases, and   wherein the production of water is reduced more than if no fluid was introduced to the formation.   
     
     
         2 . The method of  claim 1 , wherein the organosilica compound anchors the relative permeability modifier to the formation surfaces. 
     
     
         3 . The method of  claim 1 , wherein the oil-soluble resin acid is abietic acid, abieta-7,13-dien-18-oic acid, 13-isopropylpodocarpa-7,13-dien-15-oic acid, neoabietic acid, dehydroabietic acid, palustric acid, levopimaric acid, or a combination thereof. 
     
     
         4 . The method of  claim 1 , wherein the oil-soluble resin acid comprises a calcium salt of abietic acid. 
     
     
         5 . The method of  claim 1 , wherein the oil-soluble resin acid is pimaric acid, pimara-8(14),15-dien-18-oic acid, isopimaric acids, or a combination thereof. 
     
     
         6 . The method of  claim 1 , wherein the organosilicon compound is an organosilane halide or an organosilane alkoxide. 
     
     
         7 . The method of  claim 1 , wherein organosilicon compound is silanol, silanediol, and/or silanetriol. 
     
     
         8 . The method of  claim 1 , wherein the organosilicon compound is organosilane halide, silanes, alkoxysilanes, organosilazane compounds, and/or polymeric silicon compounds. 
     
     
         9 . The method of  claim 1 , wherein the organosilicon compound comprises silanol. 
     
     
         10 . The method of  claim 1 , wherein a temperature of the formation is 300 deg F. or lower. 
     
     
         11 . The method of  claim 1 , wherein a pressure of the formation is 1000 psi or lower. 
     
     
         12 . A method of reducing water production within a subterranean formation, comprising:
 forming a fluid comprising an oil-soluble resin acid and an organosilicon compound; and   introducing the fluid to the formation;   wherein the production of water is reduced more than if no fluid was introduced to the formation.   
     
     
         13 . The method of  claim 12 , wherein the oil-soluble resin acid is abietic acid, abieta-7,13-dien-18-oic acid, 13-isopropylpodocarpa-7,13-dien-15-oic acid, neoabietic acid, dehydroabietic acid, palustric acid, levopimaric acid, or a combination thereof. 
     
     
         14 . The method of  claim 12 , wherein the oil-soluble resin acid comprises a calcium salt of abietic acid. 
     
     
         15 . The method of  claim 12 , wherein the oil-soluble resin acid is pimaric acid, pimara-8(14),15-dien-18-oic acid, isopimaric acids, or a combination thereof. 
     
     
         16 . The method of  claim 12 , wherein the organosilicon compound is an organosilane halide or an organosilane alkoxide. 
     
     
         17 . The method of  claim 12 , wherein organosilicon compound is silanol, silanediol, and/or silanetriol. 
     
     
         18 . The method of  claim 12 , wherein the organosilicon compound is organosilane halide, silanes, alkoxysilanes, organosilazane compounds, and/or polymeric silicon compounds. 
     
     
         19 . The method of  claim 12 , wherein the organosilicon compound comprises silanol. 
     
     
         20 . The method of  claim 1 , wherein a temperature of the formation is 300 deg F. or lower and wherein a pressure of the formation is 1000 psi or lower.
