Abstract

The present invention generally relates to controlling the flow of fluids in a wellbore. In one aspect, a valve for selectively closing a flow path through a wellbore in a first direction is provided. The valve includes a body and a piston surface formable across the flow path in the first direction. The piston surface is formed at an end of a shiftable member annularly disposed in the body. The valve further includes a flapper member, the flapper member closable to seal the flow path when the shiftable member moves from a first position to a second position due to fluid flow acting on the piston surface. In another aspect, a valve for selectively closing a flow path through a wellbore in a single direction is provided. In yet another aspect, a method for selectively closing a flow path through a wellbore in a first direction is provided.

Claims (20)

Claims:
1. A valve for selectively closing a flow path through a wellbore in a first direction, the valve comprising:
a body;
a piston surface formable across the flow path in the first direction, the piston surface formed at an end of a shiftable member annularly disposed in the body;
and a flapper member, the flapper member closable to seal the flow path when the shiftable member moves from a first position to a second position due to fluid flow acting on the piston surface.
2. The valve of claim 1, wherein the piston surface includes a plurality of members.
3. The valve of claim 2, wherein each member is annularly disposed within the shiftable member.
4. The valve of claim 2, wherein each member is biased inward toward a centerline of the body.
5. The valve of claim 1, wherein the piston surface is formable across the flow path upon fluid flow in a second direction.
6. The valve of claim 1, wherein the flapper member is movable between an open position and a closed position.
7. The valve of claim 6, wherein the flow tube retains the flapper member in the open position when the flow tube is in the first position.
8. The valve of claim 1, wherein the piston surface is coated with an abrasion resistant material.
9. The valve of claim 1, wherein the shiftable member is biased in the first position by a biasing member.
8 A valve for selectively closing a flow path through a wellbore in a single direction, the valve comprising:
a housing;
a variable piston surface area formable across the flow path in the single direction;
a flow tube axially movable within the housing between a first and a second position due to fluid flow acting on the variable piston surface; and a flapper for closing the flow path through the valve upon movement of the flow tube to the second position.
11. The valve of claim 10, wherein the variable piston surface includes a plurality of members.
12. The valve of claim 11, wherein each member is movable between a smaller surface area position and a larger surface area position.
13. The valve of claim 12, wherein each member is biased in the larger surface area position.
14. The valve of claim 10, wherein the variable piston surface area is formable across the flow path upon fluid flow in a direction opposite the single direction.
15. A method for selectively closing a flow path through a wellbore in a first direction, the method comprising:
positioning a valve in the wellbore, the valve having a body, a formable piston surface at an end of a shiftable member, and a flapper member;
reducing the flow in the first direction, thereby forming the piston surface;
commencing a flow in a second direction against the piston surface to move the shiftable member away from a position adjacent the flapper member; and closing the flapper member to seal the flow path through the wellbore.
16. The method of claim 15, wherein the piston surface includes a plurality of members.
17. The method of claim 16, further including moving the plurality of members from an open position to a closed position to form the piston surface.
18. The method of claim 17, further including biasing the plurality of members in the closed position.
19. The method of claim 15, further including reducing the flow in the second direction to move the shiftable member adjacent the flapper, thereby opening the flow path in the first direction.
20. The method of claim 19, further including locking the valve in an open position to maintain the flow path through the wellbore.
