Abstract: Liquid water soluble polymer suspensions in non-aqueous solvents are extremely stable over long periods of time with minimum separation of the solvent and no hard packing of the dispersed water soluble polymer. The suspensions enable a user to rapidly add the suspension to water, being mixed at low speeds, without the formation of lumps or fisheyes and without generating fugitive dust in the process. The suspensions are environmentally safe and biodegradable. Unlike many other liquid polymer suspensions, the suspensions exhibit minimal oil or grease upon dilution. They contain no surfactants that can add to the oil and grease determination. The suspensions and the fluids produced by diluting the fluids to a working concentration of the water soluble polymer exhibit low toxicity to marine organisms and to humans. The suspensions can be manufactured from ingredients suitable for use in personal care applications such as cosmetics, shampoos and the like.

Abstract: A composition of an aqueous, an aqueous acid, and an aqueous alkaline foaming additive (“foamer”) functions in a wide pH range and under conditions of salt, alcohol, and hydrocarbon contamination. The foaming additive (“foamer”) composition includes a mixture of a salt of an alkyl ether sulfate surfactant, a polymer or combination of polymers, and either a water miscible solvent for the liquid foamer additive or a silicon compound for a substantially anhydrous foamer additive.

Abstract: A composition for delaying the cross-linking of water soluble polymer solutions includes a boron source suspended by an organophilic clay in a solution of a non-aqueous solvent. One process of manufacturing the composition includes the steps of first suspending the organophilic clay in the non-aqueous solvent and then suspending the boron source in the organophilic clay-non-aqueous solvent suspension. Another process of manufacturing composition includes the steps of first mixing the boron source and the organophilic clay to form a dry mixture and then suspending the dry mixture of the boron source and the organophilic clay in a non-aqueous solvent. In a method of hydraulically fracturing a formation, a water soluble polymer solution with a pH between about 8.5 and 12.5 and the boron source suspended by the organophilic clay in the solution of the non-aqueous solvent are pumped into the formation under sufficient pressure to cause a fracture in the formation rock.

Abstract: A cement composition includes cement, water in an amount from about 30% to 200% by weight of cement, and an interpolymer latex in an amount from about 10% to 50% by weight of cement. The interpolymer latex includes at least one conjugated diene monomer having 4 to 8 carbon atoms in an amount from about 5% to 95% by weight of the interpolymer latex, at least one vinyl aromatic monomer having 8 to 12 carbon atoms in an amount from about 5% to 95% by weight of the interpolymer latex, and a copolymerizable functional monomer in an amount from about 0.5% to 50% by weight of the interpolymer latex. A method of making a cement composition involves placing the above ingredients in a suitable mixer well known to those of ordinary skill in the art and mixing the ingredients until they form the cement composition.

Abstract: A stable, non-aqueous liquid suspension of delayed boron cross-linkers comprises an anhydrous boron compound or a sparingly soluble borate suspended in a mixture of mineral spirits (commonly termed as naphtha) and a resin. Anhydrous boron compounds suitable for suspension include, but are not limited to, anhydrous borax, anhydrous boric acid, or a mixture of both the anhydrous borax and anhydrous boric acid. Sparingly soluble borates suitable for suspension include, but are not limited to, alkaline earth metal borates, alkali metal borates, or a mixture thereof. The mixture between the mineral spirits and resin produces a mineral spirits-resin solution. Alternatively, the mineral spirits may be replaced with a suitable oil which forms an oil-resin solution when mixed with the resin. The oil-resin solution suspends the anhydrous boron compound or the sparingly soluble borate to produce a stable, non-aqueous liquid suspension of delayed boron cross-linkers.
