Claim 17:
18. A method for monitoring plunger parameters within a wellbore corresponding to a plunger-lifted well, wherein the wellbore comprises a production tubing with magnetic sensor systems disposed along the production tubing, and wherein the method comprises:
sensing, via a magnetic sensor within each magnetic sensor system, a passage of a metallic plunger traveling through the production tubing, a plurality of mandrels being disposed along the production tubing, each of the plurality of mandrels having a lug that secures a corresponding gas lift valve and a corresponding reverse-flow check valve within each of the mandrels, and wherein the magnetic sensor systems (i) are designed to be installed between each of the lugs and corresponding reverse-flow check valves, or (ii) are configured to replace the corresponding reserve-flow check valve between the lug and the corresponding gas lift valve; and
transmitting resulting electrical sensor signals to a computing system located at the surface, wherein the electrical sensor signals comprise data relating to a time at which the metallic plunger passed each magnetic sensor system.
