Abstract: A plunger lift system, as well as a method for monitoring plunger parameters within a wellbore using such a plunger lift system, are provided. The plunger lift system includes a lubricator attached to a wellhead at the surface and a plunger dimensioned to travel through the production tubing upon being released from the lubricator. The plunger lift system also includes magnetic sensor systems installed along the production tubing, where each magnetic sensor system includes a magnetic sensor for detecting the passage of the plunger as it travels through the production tubing, as well a communication device for transmitting communication signals between the magnetic sensor systems and a computing system located at the surface, where the computing system includes a processor and a non-transitory, computer-readable storage medium including computer-executable instructions that direct the processor to dynamically determine the plunger position and/or velocity based on the received communication signals.

Abstract: An electric submersible pump (ESP) system is described herein. The ESP system includes a pump and a motor connected to drive the pump. The pump and motor are disposed to pump fluid into production tubing in a wellbore. A connector is in fluid communication with the production tubing and the connector contains a receptacle to receive a plug. A fixed power cable section is connected at a first end to power the motor. The fixed power cable section is fixedly connected at a second end to the receptacle of the connector. Also included in the ESP system is an ESP power cable that extends through the production tubing to an ESP surface unit. The ESP power cable includes a removable plug to engage the receptacle of the connector.
