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.
