Flow control valve for use in completion of a wellbore

Abstract

A flow control valve (FCV) tool for a wellbore lined with a tubing string including a plurality of ports is presented. The FCV tool includes a body with a lower housing and an upper housing, the upper housing adapted to enable establishing a fluid path between the annulus of the wellbore and the plurality of ports. The lower housing and the upper housing form a pocket therebetween. The FCV valve also includes a unidirectional flow control valve designed to be received in the pocket and adapted to switch between a closed position and an open position and between the open position and the closed position based on a pressure differential between the annulus pressure and the internal pressure of the tubing string. The FCV tool enables multiple completion operations during the closed or open position of the valve.
