  • Downhole valve for preventing zonal cross-flow
    Patent number: 7708074
    Abstract: A flow control valve for use in a downhole completion tubing string, where the control valve prevents cross flow between producing zones. The control valve comprises a housing forming a plenum therein, a tubular member having a perforated end disposed in the housing, and a plug assembly disposed in the end of the tubular member having perforations. The plug assembly comprises a shaft reciprocatingly disposed in the tubular member. Produced fluids flow within the tubular member, through the perforations to the plenum, and outside of the control valve through corresponding perforations formed in the disk and housing. When pressure in the completion tubing string exceeds produced fluid pressure, the plug will close thereby preventing fluid flow from the completion tubing to the tubular member.
