This article describes the implementation of a better performance of the ESP equipment to improve and maintain production in Tello field, focus on one of the most important root cause of failure in the Tello field that was "well geometry" referring to collapsing and no uniforms 7" and 9-5/8" casings new technology, reducing costs with a better down hole installation velocity, eliminating the stuck risk, and less failure services.

With efficient solutions of the problem using ESP slim application with high load shaft thru a significant difference of diameter on a big range of flow rate was reduce the probability of a MLE damage and scratch the equipment with the casing, as well the MWI (measure while installing) it’s been implemented on each service to eliminate the verification of electrical continuity in ESP installations.
