  • Annular controlled safety valve system and method
    Patent number: 11041365
    Abstract: A system for operating a downhole system in a wellbore having pressure inlet ports formed in the production tubing, the one or more pressure inlet ports extending through the production tubing between the annular area and the outer surface of the conduit, the one or more pressure inlet ports being situated below a first top sealing device relative to the conduit. The system includes an annular pressure control valve coupled to a metal conduit below the one or more pressure inlet ports in the wellbore, the annular pressure control valve being configurable in an open position and in a closed position, where the annular pressure control valve transitions between the closed position and the open position responsive to the annular pressure. The system includes a second bottom sealing device coupled to a bottom portion of the conduit below the annular pressure control valve.
