US Patent 7373976 Well production optimizing system

A method and system for controlling a producing cycle in a well, during the production cycle, for optimizing production from the well including disrupting fluid in a wellbore with a pulse generator to create a pressure pulse transmitted through the fluid in the wellbore, detecting the pressure pulse created and the pressure pulse reflected from objects located within the wellbore, wherein the objects may include a liquid/gas interface and a producing apparatus such as a plunger, converting the detection of the pressure pulse and the reflected pressure pulses to a signal, computing the signals to determine the well status and controlling production of the fluid from the wellbore based on the well status.
