Tubular actuator, system and method
View Patent ↗A tubular actuating system includes a tubular, a plurality of same plugs runnable within the tubular, an actuator disposed within the tubular, and a seatable member disposed at the actuator configured to be respositionable relative to the actuator between an unseated position and a seated position upon passage of at least one of the plurality of same plugs.
1. A tubular actuating system, comprising:
a tubular;
a plurality of same plugs runnable within the tubular;
an actuator disposed within the tubular; and
a flapper disposed at the actuator configured to be repositionable relative to the actuator between an unseated position and a seated position upon passage of a second of the plurality of same plugs but not upon passage of a first of the plurality of same plugs, the actuator being configured to be directly modified to engage the second of the plurality of same plugs in response to engagement of the first of the plurality of same plugs with the actuator and passage of the first of the plurality of same plugs from a first end of the actuator to a second end of the actuator, the tubular actuator being configured to actuate in response to pressure built against the flapper in a same direction as the plugs were run.
2. The tubular actuating system of claim 1 , wherein the plurality of same plugs are balls.
3. The tubular actuating system of claim 1 , further comprising a sleeve in operable communication with the flapper and the actuator such that the sleeve prevents repositioning of the flapper until being moved by at least one of the plurality of same plugs.
4. The tubular actuating system of claim 3 , wherein the sleeve is configured to be repositioned in response to contact by at least one of the plurality of same plugs.
5. The tubular actuating system of claim 3 , further comprising a collar in operable communication with the sleeve configured to prevent repositioning of the sleeve until after the collar has been repositioned.
6. The tubular actuating system of claim 5 , wherein the collar is configured to be repositioned in response to being moved by a first of the plurality of same plugs.
7. The tubular actuating system of claim 5 , wherein the collar is configured to allow passage of a first of the plurality of same plugs after repositioning thereof.
8. The tubular actuating system of claim 7 , wherein the actuator remains unactuated after passage of the first plug thereby allowing the first plug to actuate another device positioned within the tubular.
9. The tubular actuating system of claim 1 , wherein the flapper is biased toward the seated position.
10. The tubular actuating system of claim 1 , wherein the tubular includes at least one port therethrough openable by actuation of the actuator.
11. The tubular actuating system of claim 10 , wherein the at least one port is configured to allow fracturing of a formation therethrough.
12. The tubular actuating system of claim 10 , wherein the at least one port is configured to allow fluid treating of a formation therethrough.
13. A method of actuating a tubular actuator, comprising:
running a first runnable member within a tubular;
engaging the tubular actuator with the first runnable member;
passing the runnable member by the tubular actuator without seating a flapper;
directly altering the tubular actuator with the first runnable member to a configuration engagable by a second runnable member;
running a second runnable member dimensioned the same as the first runnable member within the tubular;
engaging the tubular actuator with the second runnable member, thereby repositioning the flapper;
seating the flapper; and
pressuring up against the seated flapper in a same direction that the runnable members were run to actuate the tubular actuator.
14. The method of actuating a tubular actuator of claim 13 , further comprising repositioning a sleeve relative to the tubular actuator with the runnable member.
15. The method of actuating a tubular actuator of claim 14 , further comprising repositioning a collar relative to the tubular actuator with a first runnable member before repositioning the sleeve with a second runnable member.
16. The method of actuating a tubular actuator of claim 15 , wherein the first runnable member and the second runnable member have substantially the same dimensions.
17. The method of actuating a tubular actuator of claim 15 , wherein the collar prevents repositioning of the sleeve until the collar has been repositioned.
18. The method of actuating a tubular actuator of claim 13 , further comprising passing a first runnable member by the tubular actuator.
19. A tubular actuator comprising:
a body disposable within a tubular being movable relative to the tubular;
a sleeve being movable relative to the body by a runnable member being engaged therewith; and
a flapper being repositionable relative to the body from an unseated position to a seated position upon movement of the sleeve, the sleeve being directly alterable to be engagably movable by a second runnable member in direct response to engagement of a first runnable member with the tubular actuator and passage of the first runnable member from a first end of the tubular actuator to a second end of the tubular actuator, the tubular actuator being actuatable in response to pressure built against the seated flapper in a same direction as the runnable members were run.
20. The tubular actuator of claim 19 , wherein the body is configured to move relative to the tubular in response to pressure applied against the flapper in the seated position.
