Implementation of High-Efficiency ESP Pumps in CPO-09 Field: A Case Study on Production Improvement, Mechanical Load Reduction, Energy Efficiency, and Performance Under Heavy Crude and High TDH Conditions

Abstract The Akacías Field in Ecopetrol's CPO09 Block produces extra heavy crude under high viscosity and high TDH conditions that impose significant mechanical and hydraulic stresses on conventional ESP systems. These operating constraints—combined with the requirement to maintain low flowing bottomhole pressure (PWF) to preserve reservoir management strategy—often force traditional pumps to operate away from their best efficiency point (BEP), increasing axial loads, vibration, energy consumpti
