This study analyzes a comprehensive dataset of mid-to-late life Electric Submersible Pump (ESP) designs deployed in Delaware Basin wells to identify the most effective configurations for high Gas Volume Fraction (GVF) environments. Downhole GVFs are normalized across wells, and ESP designs are categorized by pump stage count, gas-handling pump type, gas separator configuration, and casing size. Cumulative distribution functions (CDFs) are used to evaluate statistical performance differences among these design groups, highlighting which configurations best accommodate elevated GVF conditions. Additionally, run life statistics are assessed using CDFs to determine the optimal ESP design for each installation scenario. Final, relative recommendations are made to balance reliability and produce at maximized GVFs for multiple well conditions.
