Abstract

A hydrostatic support valve for use above or below an electrical submersible pump (ESP) in a well bore. The valve includes oppositely arranged spring biased pistons (46, 48). The springs (44, 78) are selected so that a relatively strong spring is used to support a column of fluid and close the valve in the vent of loss of production fluid pressure. Increasing fluid pressure from surface can be used to switch the valve and allow fluid to be pumped through the valve to the formation below the ESP. A collet and key arrangement between the pistons is described which assists in switching the valve.
