Abstract: One or more balanced gas lift valves mounted on an oil production tube deep in a well are responsive to a remote valve control transmitter at the surface for controlling the ejection of a fluid, as a gas for example, into the production tube of oil for decreasing the specific gravity for lifting the oil and for increased production of the oil. This electronic remote controlled gas lift has fluid vent means therein for equalizing the fluid pressure on all sides and both ends thereof for reducing resistance to movement for thus requiring minimum energy for operation thereof, and for providing a highly efficient gas lift system for lifting oil in the well.

Abstract: A method for lifting oil from the bottom of a well comprises, (1) injecting a fluid of less specific gravity into the well with a fluid flow control valve, and (2) equalizing the fluid pressure on all sides thereof for making the fluid flow control valve balanced and frictionless as the fluid of less specific gravity is ejected thus requiring a minimum of energy for operation thereof for providing a highly efficient lifting of the oil in the well.

Abstract: An improved conventional type of gas lift valve and mandrel combination. It has a large area screen which encloses the valve and prevents it from having the inlet port and/or its integral small area screen, become plugged.
