CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of U.S. Application No. 15/671,488, filed on August 8, 2017, which is incorporated herein by reference in its entirety.
BACKGROUND
[00021 Resource exploration and recovery systems often employ inflow control devices (ICD) to enhance production by equalizing inflow along a length of a portion of a wellbore. Often times, multiple ICDs are employed along a length of a string of tubular members. Each ICD may be separately controllable to establish a fluid flow at a selected velocity. ICDs may be controlled by an actuator valve (AV). One or more AV's is selectively activated to establish a desired opening of each ICD.
[0003] AVs typically include a piston, a collar, a shear pin, a spring, a ball bearing and a magnet. The piston is coupled to the collar through the shear pin and installed into an orifice. The piston is held in place by the ball bearing. To activate, fluid pressure may be applied to the piston. The fluid pressure causes the piston to shift breaking the shear pin and releasing the bearing. The bearing is captured by the magnet. An alleviation of the fluid pressure allows the spring to force the piston from the orifice.

DETAILED DESCRIPTION
[0016] A detailed description of one or more embodiments of the disclosed apparatus and method are presented herein by way of exemplification and not limitation with reference to the Figures.
[0017] A resource recovery and exploration system, in accordance with an exemplary embodiment, is indicated generally at 2, in FIG. 1. Resource exploration and recovery system 2 should be understood to include well drilling operations, resource extraction and recovery, CO2 sequestration, and the like. Resource exploration and recovery system 2 may include a surface system 4 operatively connected to a downhole system 6.
Surface system 4 may include pumps 8 that aid in completion and/or extraction processes as well as fluid storage 10. Fluid storage 10 may contain a drilling fluid or completion fluid (not shown) or other fluid which may be introduced into downhole system 6.
[0018] Downhole system 6 may include a downhole string 20 formed from a plurality of tubular components, one of which is indicated at 21 that is extended into a wellbore 24 formed in formation 26. Wellbore 24 includes an annular wall 28 that may be defined by a
2 wellbore casing 29 provided in wellbore 24. Of course, it is to be understood, that annular wall 28 may also be defined by formation 26. Tubular 21 supports an inflow control device (ICD) 32 provided with an actuator valve (AV) 36.
[0019] Referring to FIG. 2, AV 36 includes a valve body 40 having a piston member receiver 42 including an inner wall 44 defining a passage 46. Passage 46 includes a first end 48 that may be an inlet and a second end 49 that may be an outlet. Inner wall 44 includes an annular recess 53 defining a first annular shoulder 54 and a second annular recess (not separately labeled) defining a second annular shoulder 56. Valve body 40 is also shown to include an outer seal 60 and an inner seal 62. A unitary piston member 70 is arranged in piston member receiver 42.
[0020] Referring to FIG. 3, unitary piston member 70 include a unitary body 75 having a first portion (not separately labeled) defining a piston portion 78 and a second portion (also not separately labeled) defining a piston ring member 80. Piston portion 78 and piston ring member 80 are connected through one or more shear tabs 83. Shear tabs 83 create a gap 84 between piston portion and piston ring member 80. Shear tabs 83, when severed, allow piston portion 78 and piston ring member 80 to be ejected from piston member receiver 42. At this point, it should be understood that the term "unitary" describes that piston member 80 is formed as one component without the use of joints or the like that unite components. Unitary piston member could, for example, be formed through an additive manufacturing process.
[0021] in accordance with an aspect of an exemplary embodiment, piston portion includes a first end section, a second end section, and an intermediate portion. A first ball receiving recess 91 and a second ball receiving recess 92 may be formed at second end 87.
Each ball receiving recess 91, 92, is receptive to a corresponding first ball bearing 94 and a second ball bearing 95. First and second ball bearings 94 and 95 engage with second annular shoulder 56 to retain unitary piston member 70 within piston member receiver 42. First end section may support an activation member 98 that is selectively exposed to fluid pressure.
Piston portion 78 may also include an annular recess 100 that is receptive of an 0-ring 101 (FIG. 2). Annular recess 100 may be manufactures with piston member 70 or formed later through, for example, a machining process.
[0022] Reference will follow to FIG. 4 with continued reference to FIGS. 2 and
[0019] Referring to FIG. 2, AV 36 includes a valve body 40 having a piston member receiver 42 including an inner wall 44 defining a passage 46. Passage 46 includes a first end 48 that may be an inlet and a second end 49 that may be an outlet. Inner wall 44 includes an annular recess 53 defining a first annular shoulder 54 and a second annular recess (not separately labeled) defining a second annular shoulder 56. Valve body 40 is also shown to include an outer seal 60 and an inner seal 62. A unitary piston member 70 is arranged in piston member receiver 42.
[0020] Referring to FIG. 3, unitary piston member 70 include a unitary body 75 having a first portion (not separately labeled) defining a piston portion 78 and a second portion (also not separately labeled) defining a piston ring member 80. Piston portion 78 and piston ring member 80 are connected through one or more shear tabs 83. Shear tabs 83 create a gap 84 between piston portion and piston ring member 80. Shear tabs 83, when severed, allow piston portion 78 and piston ring member 80 to be ejected from piston member receiver 42. At this point, it should be understood that the term "unitary" describes that piston member 80 is formed as one component without the use of joints or the like that unite components. Unitary piston member could, for example, be formed through an additive manufacturing process.
[0021] in accordance with an aspect of an exemplary embodiment, piston portion includes a first end section, a second end section, and an intermediate portion. A first ball receiving recess 91 and a second ball receiving recess 92 may be formed at second end 87.
Each ball receiving recess 91, 92, is receptive to a corresponding first ball bearing 94 and a second ball bearing 95. First and second ball bearings 94 and 95 engage with second annular shoulder 56 to retain unitary piston member 70 within piston member receiver 42. First end section may support an activation member 98 that is selectively exposed to fluid pressure.
Piston portion 78 may also include an annular recess 100 that is receptive of an 0-ring 101 (FIG. 2). Annular recess 100 may be manufactures with piston member 70 or formed later through, for example, a machining process.
[0022] Reference will follow to FIG. 4 with continued reference to FIGS. 2 and
3 in describing piston ring member 80 in accordance with an exemplary aspect.
Piston ring member 80 includes a first section 106 having a first diameter and a second section 107 having a second diameter that is greater than the first diameter. A step section 108 is disposed between first section 106 and second section 107. First section 106 is sized so as to be received in first end 48 of passage 46. Piston ring member 80 also includes an inner surface 111 from which extend shear tabs 83. As shown in FIG. 2, a spring 115 is arranged in first annular recess 52 between first annular shoulder 54 and piston ring member 80.
[0023] In operation, fluid pressure may be applied to activation member 98 causing piston portion 78 to shift into piston member receiver 42. The shifting of piston portion 78 causes shear tabs 83 to break. Piston portion 78 then axially translates relative to piston ring member 80. As piston portion 78 shift, first and second ball bearings 94 and 95 may disengage from second annular shoulder 56 and be released from corresponding ones of first and second ball bearing receiving recesses 91 and 92. First and second ball bearings 94 and 95 may then be captured by a magnet (not shown) in valve body 40. Fluid pressure may be removed so that spring 115 may eject unitary piston member 70 from piston member receiver 42. At this point, a fluid flow may pass through piston member receiver 42.
The fluid flow may be employed to activate aspects of ICD 32.
[0024] Reference will now follow to FIG. 5 in describing a unitary piston member 130 in accordance with another aspect of an exemplary embodiment. Unitary piston member 130 includes a unitary body 132 having a piston portion 134, and a piston ring member 136.
Unitary piston member 130 is received by a piston member receiver 139 formed in an AV
138 shown in FIG. 6. Piston member receiver 139 include a passage 140 having a first annular recess 141 having an annular shoulder 142 and a second annular recess 143.
[0025] Piston portion 134 includes a first end section 145, a second end section 146 and an intermediate portion 148 extending therebetween. Piston portion 34 includes a plurality of cantilevered fingers 152 arranged between intermediate portion 148 and second end 146. Each of the plurality of cantilevered fingers 152 includes a first radially outwardly directed projection 154 and a second radially outwardly directed projection 155. First radially outwardly directed projection 154 is configured to interact with second annular recess 143 to retain unitary piston member 130 within piston member receiver 139.
Cantilevered fingers 152 are defined by a plurality of slots 157 that spiral about piston portion 134. It should be understood that while slots 157 are shown spiraling about piston portion 134, the slots could also take on other forms. Further, cantilevered fingers 152 may take on other geometries including non-cantilevered arrangements.
[0026] Piston portion 134 also includes a stopper 160 that limits axial travel within piston member receiver 139. Stopper 160 includes a central bore 162 having an annular shoulder 164 which, as will be discussed herein, selectively cooperates with second radially
Piston ring member 80 includes a first section 106 having a first diameter and a second section 107 having a second diameter that is greater than the first diameter. A step section 108 is disposed between first section 106 and second section 107. First section 106 is sized so as to be received in first end 48 of passage 46. Piston ring member 80 also includes an inner surface 111 from which extend shear tabs 83. As shown in FIG. 2, a spring 115 is arranged in first annular recess 52 between first annular shoulder 54 and piston ring member 80.
[0023] In operation, fluid pressure may be applied to activation member 98 causing piston portion 78 to shift into piston member receiver 42. The shifting of piston portion 78 causes shear tabs 83 to break. Piston portion 78 then axially translates relative to piston ring member 80. As piston portion 78 shift, first and second ball bearings 94 and 95 may disengage from second annular shoulder 56 and be released from corresponding ones of first and second ball bearing receiving recesses 91 and 92. First and second ball bearings 94 and 95 may then be captured by a magnet (not shown) in valve body 40. Fluid pressure may be removed so that spring 115 may eject unitary piston member 70 from piston member receiver 42. At this point, a fluid flow may pass through piston member receiver 42.
The fluid flow may be employed to activate aspects of ICD 32.
[0024] Reference will now follow to FIG. 5 in describing a unitary piston member 130 in accordance with another aspect of an exemplary embodiment. Unitary piston member 130 includes a unitary body 132 having a piston portion 134, and a piston ring member 136.
Unitary piston member 130 is received by a piston member receiver 139 formed in an AV
138 shown in FIG. 6. Piston member receiver 139 include a passage 140 having a first annular recess 141 having an annular shoulder 142 and a second annular recess 143.
[0025] Piston portion 134 includes a first end section 145, a second end section 146 and an intermediate portion 148 extending therebetween. Piston portion 34 includes a plurality of cantilevered fingers 152 arranged between intermediate portion 148 and second end 146. Each of the plurality of cantilevered fingers 152 includes a first radially outwardly directed projection 154 and a second radially outwardly directed projection 155. First radially outwardly directed projection 154 is configured to interact with second annular recess 143 to retain unitary piston member 130 within piston member receiver 139.
Cantilevered fingers 152 are defined by a plurality of slots 157 that spiral about piston portion 134. It should be understood that while slots 157 are shown spiraling about piston portion 134, the slots could also take on other forms. Further, cantilevered fingers 152 may take on other geometries including non-cantilevered arrangements.
[0026] Piston portion 134 also includes a stopper 160 that limits axial travel within piston member receiver 139. Stopper 160 includes a central bore 162 having an annular shoulder 164 which, as will be discussed herein, selectively cooperates with second radially
4 outwardly directed projection 155. Stopper 160 is connected to a hub 168 formed centrally relative to cantilevered fingers 152. A support 170 extends from hub 168 into central bore 162. Support 170 is connected to hub 168 through one or more shear elements 173. Stopper 160, support 170, and shear elements 173 are all part of unitary piston member 130. Piston.
portion 134 is connected to piston ring member 136 through a plurality of shear tabs 176.
Shear tabs 176 establish a gap 178 between piston portion 134 and piston ring member 136.
A spring 181 is arranged in first annular recess 141 between shoulder 142 and piston ring member 136.
[0027] Reference will follow to FIGS. 7-9, with continued reference to FIGS. 5 and 6 in describing a method of operation of AV 138. Fluid pressure is applied to piston portion 134 at first end section 145. The fluid pressure causes piston portion 134 to shift within piston member receiver 139 relative to piston ring member 136. The shifting of piston portion 134 causes shear tab(s) 178 to shear thrcing stopper 160 to bottom out in piston member receiver 139. Once stopper 160 bottoms out, further shifting of piston portion 134 causes shear element(s) 173 to shear allowing cantilevered fingers 152 to deflect and second radially outwardly directed projections 155 to be captured by annular shoulder 164 in central bore 162. Fluid pressure may be alleviated such that spring 181 ejects unitary piston member 130 from AV 138. At this point, fluid may flow through passage 140 to actuate elements within ICD 32.
[0028] Set forth below are some embodiments of the foregoing disclosure:

[0050] The teachings of the present disclosure may be used in a variety of well operations. These operations may involve using one or more treatment agents to treat a formation, the fluids resident in a formation, a wellbore, and / or equipment in the wellbore, such as production tubing. The treatment agents may be in the form of liquids, gases, solids, semi-solids, and mixtures thereof Illustrative treatment agents include, but are not limited to, fracturing fluids, acids, steam, water, brine, anti-corrosion agents, cement, permeability modifiers, drilling muds, emulsifiers, demulsifiers, tracers, flow improvers etc. Illustrative well operations include, but are not limited to, hydraulic fracturing, stimulation, tracer injection, cleaning, acidizing, steam injection, water flooding, cementing, etc.
[0051] While the invention has been described with reference to an exemplary embodiment or embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof Therefore, it is intended that the invention not be limited to the particular embodiment disclosed as the best mode contemplated for carrying out this invention, but that the invention will include all embodiments falling within the scope of the claims.

portion 134 is connected to piston ring member 136 through a plurality of shear tabs 176.
Shear tabs 176 establish a gap 178 between piston portion 134 and piston ring member 136.
A spring 181 is arranged in first annular recess 141 between shoulder 142 and piston ring member 136.
[0027] Reference will follow to FIGS. 7-9, with continued reference to FIGS. 5 and 6 in describing a method of operation of AV 138. Fluid pressure is applied to piston portion 134 at first end section 145. The fluid pressure causes piston portion 134 to shift within piston member receiver 139 relative to piston ring member 136. The shifting of piston portion 134 causes shear tab(s) 178 to shear thrcing stopper 160 to bottom out in piston member receiver 139. Once stopper 160 bottoms out, further shifting of piston portion 134 causes shear element(s) 173 to shear allowing cantilevered fingers 152 to deflect and second radially outwardly directed projections 155 to be captured by annular shoulder 164 in central bore 162. Fluid pressure may be alleviated such that spring 181 ejects unitary piston member 130 from AV 138. At this point, fluid may flow through passage 140 to actuate elements within ICD 32.
