(2024016) Extending The Life of An ESP While Maintaining the Ability to Inject

The purpose of this paper is to present a solution to the adverse impact of fallback sand and debris on ESPs (Electrical Submersible Pumps). When these solids accumulate on an ESP during operational shutdowns, it poses a significant risk of damage and subsequent failures upon restarting the system. The problem arises when the friction force that the motor is required to overcome exceeds the material strength of the motor shaft. This large increase in amperage damages the motor and drive shaft of the ESP.

Installing a Fallback Filter directly above the ESP efficiently captures and reintroduces accumulated solids while maintaining the ability to inject through the ESP.
