Reclosable mechanical annular flow valve

An interventionless and mechanical flow control assembly having unlimited open and close cycles for an oil or gas well comprising:

• an outer housing;
• an inner conduit disposed within the outer housing and fixed relative thereto;
• a first flow path at least partially defined by an annulus between the outer housing and the inner conduit;
• at least one flow port disposed with the first flow path for communicating flow along the first flow path when the port is open and preventing flow along the first flow path when the port is closed;
• a sealing member disposed within the device and adjacent the at least one flow port, the sealing member having at least two positions relative to the at least one port including an open position in which the sealing member does not prevent flow through the at least one port and a closed position in which the sealing member prevents flow through the at least one port;
• a tool profile disposed on the sealing member for engaging a corresponding profile on a service tool for changing the sealing member from its open to its closed position and vice versa;
• and
• an interventionless flow control device coupled to the outer housing and comprising a second flow path communicating with first flow path and a valve element disposed within the second flow path, the valve element having at least an opened and a closed position, such that fluid flowing along the first path can flow along the second flow path when the valve element is opened and cannot flow along the second flow path when the valve element is closed, the interventionless device adapted to interventionlessly change the flow condition of second flow path in response to well pressure.
