Optimizing ESP Designs – Defining Applications For Add-On Components to the Traditional ESP

A thorough set of Electrical Submersible Pump (ESP) data was analyzed to determine the impact of tapered designs and gas handling pumps on the drawdown of wells at varying conditions and the respective run life of the ESP. The operator’s ESP installations are examined, and then normalized for comparative fluid rate targets to evaluate their respective performance post-installation of varying pump designs. The analysis will demonstrate differences in intake pressures, flowrates, and relative run lives with a variety of tapered pump designs, addition of gas handling pumps, and sand separation technology. A statistical approach will also be taken, evaluating the cumulative distribution of pump intake pressures and gas rates to evaluate how each selected pump design has performed under selected parameters.
