Abstract: A system for matching the hydrocarbon reservoir inflow with the outflow of an artificial lift system utilizes an apparatus which makes real time fluid level determinations based upon shock waves detected by a surface device and inputs the observed fluid levels into a processor which controls the speed of a motor which operates a subsurface pump, so as to increase hydrocarbon production. The apparatus which makes real time fluid determinations is installed such that a gas emission port and a pressure wave pressure wave receiving port are placed within the tubing-casing annulus.

Abstract: A device for employing sonic transmissions is utilized to determine fluid level in a well or a container. The device may be utilized while the well is operating. It is known that wells replenish fluid at different rates even in the same formation or well field. Increased well production at minimum pumping cost is achieved for a given well. The device generates a sonic event through the use of a compressed fluid that is obtained from within a well. A fluid level measurement system is obtained in a well in which gas is produced under vacuum.

Abstract: A tool for use in well monitoring is described to insert devices for well fluid level control into a wellhead. The tool also permits removal of the devices for well fluid level control from an operating well for servicing. The tool also permits precise positioning of the components utilized to take measurements in the well annulus.
