A fluid product pumping system is described for deep fluid well formations including a well casing surrounding fluid product tubing string to define an annular space between the casing and the tubing string, a method of creating a valve action in the tubing string comprising the steps of: forming at least one through aperture in the product tubing string, lowering the tubing string into the well until the aperture reaches the region of the surface of the fluid to be pumped, sealing a lower region of the annular space to isolate the formation, supporting a submersible pump having a housing on a rod string within the product tubing string in a pumping relationship with the fluid, and utilizing the pump housing in cooperation with the tubing string to control fluid flow of product from the pump through the aperture by selectively positioning the pump housing above and below the aperture such that when the pump housing is below the aperature the product flows through the tubing string and through the annular space simultaneously and when the pump housing is above the aperature the product flow solely through the tubing string.
