Abstract
A tubular actuating system includes, a tubular, a plurality of same plugs runnable within the tubular, an alterable actuator disposed at the tubular that is 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 is 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, and a flapper seat movably disposed at the alterable actuator between at least a first position defined by the alterable actuator in an unaltered position and a second position defined by the alterable actuator in an altered position.
Claims18
A tubular actuating system, comprising:
- a tubular;
- a plurality of same plugs runnable within the tubular;
- an alterable actuator disposed at the tubular 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;
- and
- a flapper seat movably disposed at the alterable actuator between at least a first position defined by the alterable actuator being in an unaltered position and a second position defined by the alterable actuator being in an altered position.
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;
- passing the actuator with the first plug;
- running a second plug that is dimensioned substantially the same as the first plug within the tubular;
- seatingly engaging the actuator with the second plug;
- pressuring up against the second plug seatingly engaged with the actuator;
- and
- moving the actuator.
A tubular actuator, comprising:
- a body;
- and
- at least one seat movably disposed at the body configured to be moved during passage of a first engagable member thereby to be subsequently seatingly engagable with a subsequent engagable member, the subsequent engagable member being substantially the same as the first engagable member.
