Methods and systems for the generation of stable oil-in-water or water-in-oil emulsion for enhanced oil recovery

A method for generating a stable emulsion, the method comprising:

• pumping a motive fluid from a motive fluid tank to a first inlet of a liquid-liquid ejector located inside a suction tank;
• mixing the motive fluid with a suction fluid in the suction tank after a pressure energy of a flow of the motive fluid is converted to kinetic energy through a nozzle of the liquid-liquid ejector;
• ejecting an emulsion of the motive fluid and the suction fluid from an outlet of the liquid-liquid ejector;
• and
• collecting the emulsion in a discharge tank.

A system for generating a stable emulsion, the system comprising:

• one or more motive tanks fluidly coupled to one or more liquid-liquid ejectors, wherein the one or more motive tanks are configured to supply the one or more liquid-liquid ejectors with a motive fluid;
• one or more suction tanks fluidly coupled to the one or more liquid-liquid ejectors, wherein the one or more suction tanks are configured to supply the one or more liquid-liquid ejectors with a suction fluid,
• wherein the motive fluid and the suction fluid are mixed in the one or more liquid-liquid ejectors;
• one or more discharge tanks fluidly coupled to the one or more liquid-liquid ejectors, wherein the one or more discharge tanks are configured to collect an emulsion from the one or more liquid-liquid ejectors;
• and
• a flow line coupled to the one or more discharge tanks, wherein the flow line is configured to feed the emulsion into a formation.
