Electric submersible pumps have a good predictable performance for single-phase and low viscosity fluids. When gas is present, pump performance degradation is observed and as a consequence lift efficiency deteriorates.
Predicting this behavior is a complex task, as it is dependent on several variables such as amount of gas and liquid, intake pressure, pump geometry and speed.
This study describes and analyzes the experimental and theoretical work that has been conducted at The University of Tulsa Artificial Lift Projects Consortium (TUALP) on the two-phase behavior of ESPs, using a 22-stage mixed flow type pump to gather data on stage-wise performance, keeping constant pressure at one specific stage.
The acquired data were used to develop correlations to predict the pressure increment across the stage, and also to determine the flow regime boundaries. Air and water were used as working fluids.Download thesis (TUALP members only)
