Abstract
An electric submersible pump (ESP) gas separator is described. An ESP gas separator includes a propeller upstream of a fluid entrance to a crossover, the crossover including a production pathway and a vent pathway, and the propeller including a plurality of blades comprising washout twist, wherein gas rich fluid of multi-phase fluid traveling through the gas separator flows through the propeller and into the vent pathway, and gas poor fluid of the multi-phase fluid flows around the propeller and then through the production pathway. An ESP assembly includes a gas separator between a centrifugal pump and an induction motor, the gas separator serving as an intake for fluid into the centrifugal pump and including a propeller in a separation chamber, the propeller comprising a plurality of blades, each blade having a pitch that increases in coarseness from a hub towards a shroud of the propeller.
