Multicycle valve system and method
A multicycle valve system, including a housing, a port extending radially through the housing, a movable closure to change a condition of the port, a seat connected to the movable closure, a biaser between the housing and the closure, and a DoD object, an igniter in contact with the disappear on demand material, and a signal receiver in communication with the igniter. A method for operating a multicyclic valve system including landing an object on a seat, moving a closure by loading the object, deforming a biaser upon moving the closure, changing a condition of a port with the the closure, rendering the object incapable of remaining on the seat, and returning the closure to a position prior to moving with the biaser. A borehole system including a borehole, a string in the borehole, and a multicycle valve system as claimed disposed within or as a part of the string.
1 . A multicycle valve system, comprising:
a housing;
a port extending radially through the housing;
a repeatably movable closure positionable to change a flow condition of the port;
an object seat operably connected to the movable closure;
a biaser disposed between the housing and the movable closure and configured to close the closure;
an object including a disappear-on-demand material, an igniter disposed in physical contact with the object, the igniter in operable contact with the disappear on demand material, and a signal receiver in operable communication with the igniter;
a transmitter disposed within the housing and in operable communication with the igniter; and
a location indicator disposed to indicate a position of the closure.
2 . The system as claimed in claim 1 , wherein the transmitter is disposed in a transmitter sub disposed within the housing.
3 . The system as claimed in claim 1 , wherein the port includes an erosion resistant surface.
4 . The system as claimed in claim 1 , wherein the movable closure is a sleeve slidably disposed in the housing.
5 . The system as claimed in claim 1 , wherein the biaser is a coil spring.
6 . A borehole system comprising:
a borehole in a subsurface formation;
a string in the borehole; and
a multicycle valve system as claimed in claim 1 disposed within or as a part of the string.
7 . A method for operating a multicyclic valve system comprising:
landing an object on a seat in the system;
moving a closure of the system by loading the object;
deforming a biaser of the system upon moving the closure;
changing a flow condition of a port with the moving of the closure;
rendering the object incapable of remaining on the seat with a signal sent to the object from the housing;
returning the closure to a position prior to moving with the biaser such that subsequent action is repeatable; and
monitoring a position of the closure with a location indicator.
8 . The method as claimed in claim 7 , wherein the degrading is disappearing-on-demand.
9 . The method as claimed in claim 7 , wherein the signal is a wireless electromagnetic signal.
10 . The method as claimed in claim 7 , wherein the signal is a wireless acoustic signal.
11 . The method as claimed in claim 7 , wherein the rendering includes igniting an igniter upon receipt of the signal.
12 . The method as claimed in claim 7 , wherein the rendering includes thermally decomposing the object.
13 . The method as claimed in claim 7 , wherein the changing of flow condition is opening.
14 . The method as claimed in claim 7 , wherein the changing of flow condition is closing.
