Low viscosity acid-in-oil emulsions and methods |
摘要 |
The present invention provides low viscosity acid-in-oil emulsions, surfactant systems and methods of using the emulsions and surfactants for stimulating the production of hydrocarbons from subterranean producing formations. The low viscosity acid-in-oil emulsions are basically comprised of a hydrocarbon oil forming the external phase of the emulsion, an emulsifying agent of a type which forms and stabilizes an acid-in-oil emulsion, an emulsion viscosity reducing agent comprising a fatty ammonium salt of a fatty acid and an aqueous acid solution forming the internal phase of the emulsion.
