Tubular actuator, system and method

1. A tubular actuating system, comprising:

a tubular;

a plurality of same plugs runnable within the tubular and being dimensioned substantially the same; and

an alterable actuator including a flapper seat being alterable in response to passage of a first of the plurality of same plugs run into contact therewith, a second of the plurality of same plugs being seatingly engagable with the alterable actuator run thereagainst when in an altered condition such that pressure built up against the second of the plurality of same plugs causes actuational movement of the alterable actuator, the flapper seat being movably disposed between at least a first position defined by the alterable actuator being in an unaltered position and not seatably engagable with one of the plurality of same plugs and a second position defined by the alterable actuator being in an altered position and being seatably engagable with one of the plurality of same plugs.

2. The tubular actuating system of claim 1 , further comprising a second actuator seatingly engagable with the first of the plurality of same plugs such that pressure built up against the first of the plurality of same plugs causes actuational movement of the second actuator.

3. The tubular actuating system of claim 1 , wherein the plurality of same plugs are balls.

4. The tubular actuating system of claim 1 , further comprising a support member movable relative to the flapper seat that prevents movement of the flapper seat until the support member has been moved.

5. The tubular actuating system of claim 4 , wherein the support member is tubular.

6. The tubular actuating system of claim 4 , wherein the support member is radially expandable to allow passage of at least one of the plurality of same plugs.

7. The tubular actuating system of claim 4 , further comprising at least one release member in operable communication with the support member and the alterable actuator.

8. The tubular actuating system of claim 7 , wherein the at least one release member is a shear screw.

9. The tubular actuating system of claim 1 , further comprising at least one release member in operable communication with the alterable actuator and the tubular.

10. The tubular actuating system of claim 9 , wherein the at least one release member is a shear screw.

11. The tubular actuating system of claim 1 , further comprising a biasing member in operable communication with the flapper seat biasing the flapper seat toward the second position.

12. A method of actuating a tubular actuator, comprising:

running a first plug within a tubular;

engaging an actuator with the first plug;

altering the actuator with the first plug;

moving a flapper seat from a first position to a second position, the first position being nonseatable with a plug dimensioned substantially the same as the first plug and the second position being seatable with a plug dimensioned substantially the same as the first plug;

passing the first plug by the actuator;

running a second plug that is dimensioned substantially the same as the first plug within the tubular;

seatingly engaging the flapper seat with the second plug after the first plug has passed the actuator;

pressuring up against the second plug seatingly engaged with the flapper seat; and

moving the actuator.

13. The method of actuating a tubular actuator of claim 12 , wherein the running the first plug includes at least one of dropping and pumping the first plug.

14. The method of actuating a tubular actuator of claim 12 , wherein the moving the flapper seat includes pivotally rotating a flapper seat.

15. The method of actuating a tubular actuator of claim 12 , wherein actuating the actuator includes longitudinally moving an altered actuator.

16. A tubular actuator, comprising:

a body; and

at least one flapper seat movably disposed at the body configured to be moved and altered in response to passage of a first engagable member thereby from a position not seatable with the first engagable member to a position seatingly engagable with a subsequent engagable member, the subsequent engagable member being dimensioned substantially the same as the first engagable member, the tubular actuator being actuatable in response to movement of the body in response to pressure built against the subsequent engagable member when engaged with the at least one flapper seat.
