A plunger lift system of an oil or gas well and method of use is described. The plunger lift system includes a plunger, a sensor, a flow valve assembly, and a controller. The plunger is positioned within the tube string and travels up and down the string in response to the opening and/or closing of the flow valve assembly. The sensor is connected to the tube string and detects vibrations generated by impacts created by the plunger temporarily catching on gaps in the tube string. The sensor generates a sensor signal in response to the impacts of the plunger which are used by the controller to determine the velocity of the plunger within the tube string. If the velocity of the plunger exceeds a preselected maximum velocity, the controller selectively opens or closes the flow valve assembly to reduce the velocity of the plunger.

Velocity analyzer for objects traveling in pipes

A fluids lifting tool and analysis system. The present invention comprises a fluid lifting system for a gas well. The system comprises a lifting tool positioned in the well and a docking station at the well surface. The tool includes a processor, pressure sensors, temperature sensors, an accelerometer, and a proximity sensor. A battery in the tool is adapted to be charged by inductive coupling using coils in the docking station and the tool. The tool is released from the docking station and descends the well. During descent the tool measures elapsed time, velocity of the tool, calculates distance traveled, measures pressure and temperature, determines volumes or oil and water in the well, and senses when the tool reaches the bottom of the well. The FLT chooses to ascend the well when appropriate and transfers measured and calculated data to the docking station.
