and introducing the treatment fluid into at least a portion of a subterranean formation. ## Claims ### Claim 1 A method comprising: providing an invert emulsion treatment fluid that comprises an oleaginous external phase, and an internal phase that comprises a first component that comprises one or more alcohols, and a second component that comprises one or more polar organic compounds that are soluble in the internal phase, the one or more polar organic compounds selected from the group consisting of urea (monomeric), polyethylene oxide, polypropylene oxide, dimethyl formamide, dimethyl acetamide, n-methyl pyrrolidone, dimethyl sulfoxide, a polyamine, an ethoxylated polyamine, a propoxylated polyamine, morpholine, piperazine, dioxane, hexamethylphosphoramide (HMPA), glycine, aspartic acid, polyethylene imine, a polyphosphazene, a sugar, a carboxylic acid, an amino acid, and any combination thereof; and introducing the treatment fluid into at least a portion of a subterranean formation. ### Claim 2 (depends on 1) The method of claim 1 wherein the alcohols and the polar organic compounds are present in a total amount of at least about 40% by volume of the internal phase. ### Claim 3 (depends on 1) The method of claim 1 wherein the treatment fluid further comprises a polymeric suspending agent that comprises one or more urea linkages. ### Claim 4 (depends on 1) The method of claim 1 wherein the internal phase consists essentially of the one or more alcohols and the one or more polar organic compounds. ### Claim 5 (depends on 1) The method of claim 1 wherein the internal phase does not include a significant amount of water. ### Claim 6 (depends on 1) The method of claim 1 wherein the one or more alcohols are selected from the group consisting of: a glycerol, a polyglycerol, and any combination thereof. ### Claim 7 (depends on 1) The method of claim 1 wherein the internal phase has a water phase activity equivalent to or greater than that of an aqueous calcium chloride solution having a calcium chloride concentration of from about 100,000 ppm to about 360,000 ppm. ### Claim 8 (depends on 1) The method of claim 1 wherein the internal phase of the invert emulsion treatment fluid is salt-free. ### Claim 9 A method comprising: providing an invert emulsion drilling fluid that comprises an oleaginous external phase, and an internal phase that comprises a first component that comprises one or more alcohols, and a second component that comprises one or more polar organic compounds that are soluble in the internal phase, the one or more polar organic compounds selected from the group consisting of urea (monomeric), polyethylene oxide, polypropylene oxide, dimethyl formamide, dimethyl acetamide, n-methyl pyrrolidone, dimethyl sulfoxide, a polyamine, an ethoxylated polyamine, a propoxylated polyamine, morpholine, piperazine, dioxane, hexamethylphosphoramide (HMPA), glycine, aspartic acid, polyethylene imine, a polyphosphazene, a sugar, a carboxylic acid, an amino acid, and any combination thereof; and using the drilling fluid to drill at least a portion of a well bore penetrating at least a portion of a subterranean formation. ### Claim 10 (depends on 9) The method of claim 9 further comprising introducing the drilling fluid into the well bore using one or more pumps and a drillstring. ### Claim 11 (depends on 9) The method of claim 9 further comprising: circulating the drilling fluid out of the well bore after using the drilling fluid; and removing cuttings from the drilling fluid using a fluid processing device. ### Claim 12 (depends on 9) The method of claim 9 wherein the one or more alcohols are selected from the group consisting of: a glycerol, a polyglycerol, and any combination thereof. ### Claim 13 (depends on 9) The method of claim 9 wherein the alcohols and the polar organic compounds are present in a total amount of at least about 30% by volume of the internal phase. ### Claim 14 (depends on 9) The method of claim 9 wherein the internal phase does not include a significant amount of water. ### Claim 15 (depends on 9) The method of claim 9 wherein the portion of the subterranean formation comprises a salt formation. ### Claim 16 (depends on 9) The method of claim 9 wherein the internal phase of the invert emulsion drilling fluid is salt-free. ### Claim 17 An invert emulsion treatment fluid comprising: an oleaginous external phase; and an internal phase that comprises a first component that comprises one or more alcohols, and a second component that comprises one or more polar organic compounds that are soluble in the internal phase, the one or more polar organic compounds selected from the group consisting of urea (monomeric), polyethylene oxide, polypropylene oxide, dimethyl formamide, dimethyl acetamide, n-methyl pyrrolidone, dimethyl sulfoxide, a polyamine, an ethoxylated polyamine, a propoxylated polyamine, morpholine, piperazine, dioxane, hexamethylphosphoramide (HMPA), glycine, aspartic acid, polyethylene imine, a polyphosphazene, a sugar, a carboxylic acid, an amino acid, and any combination thereof. ### Claim 18 (depends on 17) The invert emulsion treatment fluid of claim 17 wherein the alcohols and the polar organic compounds are present in a total amount of at least about 30% by volume of the internal phase. ### Claim 19 (depends on 17) The invert emulsion treatment fluid of claim 17 wherein the internal phase does not include a significant amount of water. ### Claim 20 (depends on 17) The invert emulsion treatment fluid of claim 17 wherein the internal phase is salt-free.
