Kirkpatrick, W H; Seale, V L; Berkley, R E

These emulsifiers and the emulsions prepared therewith are especially suitable for use in the formation of acidic, water-in-oil, hydraulic-fracturing fluids for fracturing and acidizing underground formations to increase their productivity of oil and/or gas. The emulsifying agents contain one or both of the following: (1) a 9-18 carbon monocarboxylic acid fatty acid salt of a partial amide of a polyalkylene polyamine with 2-6 carbon alkylene groups and 3-5 amino nitrogens in which at least 2 amino groups are amidified with 9-18 carbon monocarboxylic fatty acids and wherein there is at least one non-amidified amino group forming a salt with the acid; (2) a polyamide of an alkylene polyamine with 2-6 carbon alkylene groups and 2-5 amino nitrogens and a 9-18 carbon monocarboxylic fatty acid. The water phase of the water-in-oil emulsion contains 5 to 25% by weight of hydrochloric acid and various percentage mixtures of the emulsifiers (1) and (2). (18 claims)
