An analysis of reliability of electric submersible centrifugal pumps

open access: yesJournal of Physics: Conference Series, 2022
Abstract The average operating time before structural and technological failures of the submersible part of a typical ESP is 64.5–81.9% of the average operating time of new ESPs. Given that the set of typical ESPs includes a significant share of repaired and mixed (equipped with new and refurbished units) installations, this fact can be ...

Operation effectiveness of wells by enhancing the electric- centrifugal pump [PDF]

open access: yesIOP Conference Series: Earth and Environmental Science, 2016
We present the method to improve the operation effectiveness of wells by enhancing the electric-centrifugal pump. Some of the best ways to extend the electric-centrifugal pumps operating lifetime is using today's techniques as well as additional protective equipment as a part of the electric-centrifugal pump.
