摘要： An apparatus, system and method for reducing gas to liquid ratios in submersible pump applications are described. A method for reducing a gas to liquid ratio (GLR) in a pumped fluid includes pumping a gas laden fluid to a surface of a subsurface formation using a downhole electric submersible pump (ESP) assembly including an ESP pump and an ESP motor, monitoring one of a load of the ESP motor, intake pressure of the ESP pump, temperature of the gas laden fluid, or a combination thereof to obtain ESP assembly condition data, determining whether a GLR of the gas laden fluid exceeds a predetermined allowable maximum based on the ESP assembly condition data, injecting liquid from an external source into the gas laden fluid, and varying a rate that the external liquid is injected based on the GLR so determined.
