PREVENTION OF FERROMAGNETIC SOLIDS DEPOSITION ON ELECTRICAL SUBMERSIBLE PUMPS (ESPS) BY MAGNETIC MEANS

摘要

A system is provided for use with an electrical submersible pump (ESP). The system includes an ESP mounted on a tubing and a magnetic field source positioned above the ESP. The magnetic field source generates a magnetic field configured to suspend iron-containing particles above a discharge of the ESP. The magnetic field prevents an accumulation of the iron-containing particles onto components of the ESP during a powered-off state of the ESP.
