Abstract

A valve assembly including a tubular having a first end, a second end, and an intermediate portion extending therebetween. The second end includes one or more openings. A pin member extends radially outwardly of the intermediate portion of the tubular. A valve member is arranged about the tubular. The valve member includes a first end portion, a second end portion and an intermediate section extending therebetween. The second end portion includes a valve element that registers with the one or more openings. An actuator sleeve is mounted to the first end of the valve member and extends about the tubular. The actuator sleeve includes a first end section, a second end section, and an inner surface extending therebetween. The inner surface includes a plurality of J-slots that are selectively receptive of the pin member to establish a position of the valve element relative to the one or more openings.

First claim

What is claimed is:

1 . A valve assembly comprising:
a tubular including a first end, a second end, and an intermediate portion extending therebetween, the second end including one or more openings; a pin member extending radially outwardly of the intermediate portion of the tubular; a valve member arranged about the tubular, the valve member including a first end portion, a second end portion and an intermediate section extending therebetween, the second end portion including a valve element that registers with the one or more openings; and an actuator sleeve mounted to the first end of the valve member and extending about the tubular, the actuator sleeve including a first end section, a second end section, and an inner surface extending therebetween, the inner surface including a plurality of J-slots that are selectively receptive of the pin member to establish a position of the valve element relative to the one or more openings.

2 . The valve assembly according to claim 1 , further comprising: a piston element formed on the intermediate portion of the tubular.

3 . The valve assembly according to claim 2 , wherein the valve member includes a first port arranged at the first end portion and a second port arranged at the first end portion, the piston element being disposed between the first end portion and the second end portion.

4 . The valve assembly according to claim 1 , wherein the plurality of J-slots includes a first plurality of J-slot members extending toward the second end section and a second plurality of J-slot members extending toward the first end section.

5 . The valve assembly according to claim 4 , wherein each of the first plurality of J-slot members include a length that is distinct from others of the plurality of J-slot members.

6 . The valve assembly according to claim 1 , wherein the plurality of J-slots are integrally formed in the inner surface.

7 . A resource exploration and recovery system comprising:
a first system; a second system including a tubular string extending into a formation, the tubular string including a valve assembly comprising:
a tubular including a first end, a second end, and an intermediate portion extending therebetween, the second end including one or more openings;
a pin member extending radially outwardly of the intermediate portion of the tubular;
a valve member arranged about the tubular, the valve member including a first end portion, a second end portion and an intermediate section extending therebetween, the second end portion including a valve element that registers with the one or more openings; and
an actuator sleeve mounted to the first end of the valve member and extending about the tubular, the actuator sleeve including a first end section, a second end section, and an inner surface extending therebetween, the inner surface including a plurality of J-slots that are selectively receptive of the pin member to establish a position of the valve element relative to the one or more openings.

8 . The resource exploration and recovery system according to claim 7 , further comprising: a piston element formed on the intermediate portion of the tubular.

9 . The resource exploration and recovery system according to claim 8 , wherein the valve member includes a first port arranged at the first end portion and a second port arranged at the first end portion, the piston element being disposed between the first end portion and the second end portion.

10 . The resource exploration and recovery system according to claim 7 , wherein the plurality of J-slots includes a first plurality of J-slot members extending toward the first end section and a second plurality of J-slot members extending toward the second end section.

11 . The resource exploration and recovery system according to claim 10 , wherein each of the first plurality of J-slot members includes a length that is distinct from others of the first plurality of J-slot members.

12 . The resource exploration and recovery system according to claim 7 , wherein the plurality of J-slots are integrally formed in the inner surface.

13 . A method of operating a valve assembly comprising:
introducing an actuation force into a valve member having a valve element including valve openings; shifting a tubular including one or more openings relative to the valve member with the actuation force; guiding a pin member projecting radially outwardly of the tubular along one of a plurality of J-slots formed in an inner surface of an actuator sleeve connected to the valve member; and seating the pin member at a terminal end portion of the one of the plurality of J-slots to selectively align a portion of the one or more openings with the corresponding ones of the valve openings of the valve element.

14 . The method of claim 13 , wherein introducing the actuation force includes applying a hydraulic pressure to the tubular through the valve member.

15 . The method of claim 13 , wherein seating the pin member at the terminal end portion of the one of the plurality of J-slots establishes a selected choke setting for the valve assembly.
