Abstract
Provided is a flow control valve, a well system, and a method. The flow control valve, in one aspect, includes a tubular configured to be positioned downhole in a wellbore, the tubular having a central longitudinal axis, and a piston located in the tubular, the piston configured to separate injection fluid located within the tubular from a working fluid located in a sealed working fluid chamber. The flow control valve, according to this aspect, further includes a valve assembly located within the tubular and coupled with the piston, wherein the piston is configured to axially slide within the tubular to move the valve assembly between an open position that provides a fluid passageway for the injection fluid from the tubular into a subterranean formation and a closed position that closes the fluid passageway for the injection fluid from the tubular into the subterranean formation, based upon a density of the injection fluid.
