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.

Apparatus, system and method for reducing gas to liquid ratios in submersible pump applications

An electric submersible pump (ESP) inverted shroud assembly is described. An ESP assembly includes an inverted shroud separating an ESP pump from a well casing, the ESP pump rotatably coupled to an ESP motor, the inverted shroud having an opening on an upstream terminal side, at least a portion of the ESP motor extending through the opening, the portion of the ESP motor extending through the opening exposed to working fluid, and the opening sealed to the working fluid. An ESP assembly includes an inverted shroud, and an ESP motor including a head, housing and base, the head of the ESP motor at least partially inside the inverted shroud, and the housing and base of the ESP motor at least partially outside the inverted shroud.
