Abstract: The present disclosure is related to a basic chemical formulation to modify the wettability of a well formation, promoting a water-wet behavior in order to increase the medium, heavy or extra-heavy crude oil production, a method to determine the right components concentration and proportions of the chemical formulation to modify the wettability in any specific type of formation-crude oil combination and a method to use the optimized chemical formulation for the treatment of a determined well.

Abstract: A viscosity reducer based on vegetable extracts of natural origin is disclosed. The vegetable extracts include a mixture of phosphoglycerides and vegetable oils. A method of reducing the viscosity in heavy and extra heavy crude oil using the viscosity reducer is also disclosed. No aromatic base solvents are needed. A reduction in diluent usage is achieved using the viscosity reducer based on vegetable extracts. The viscosity reducer composition includes a mixture of phosphoglycerides, vegetable oil, non-aromatic solvent, polycyclic aromatic hydrocarbon and stabilizer.

Abstract: A crude oil friction reducer is disclosed. The friction reducer includes water soluble anionic surfactants as active components and non-aromatic solvents. The water soluble anionic surfactants include anionic sulfonate surfactant and an anionic sulfate surfactant, such as anionic sodium sulfate surfactant, dissolved in an aqueous chelating solution. The friction reducer may also include a pH adjuster. The friction reducer is used with heavy and extra heavy crude oil.
