1. A method comprising:
providing an electrical submersible pump assembly (ESP) with a pump, an intake, a gel canister, a protector, and a motor disposed in a casing;
providing fluid communication between a production tubing and the ESP, the production tubing delivering well fluid containing solid particles and liquids from the ESP into a wellhead assembly through an inner bore of the production tubing;
locating a pressure release conduit configured in a closed state, between a canister exterior in a hydraulic communication with a canister inner chamber of the gel canister and the inner bore, wherein the closed state prevents the hydraulic communication between the canister inner chamber and the inner bore,
placing the pressure release conduit in an open state, wherein the open state allows the hydraulic communication between the canister inner chamber and the inner bore, and
delivering a canister contents to the well fluid.
