Description

BACKGROUND OF THE DISCLOSURE

1. Field of the Disclosure

The disclosure relates generally to apparatus and methods for control of fluid flow from subterranean formations into a production string in a wellbore.

2. Description of the Related Art

Hydrocarbons such as oil and gas are recovered from a subterranean formation using a well or wellbore drilled into the formation. In some cases the wellbore is completed by placing a casing along the wellbore length and perforating the casing adjacent each production zone (hydrocarbon bearing zone) to extract fluids (such as oil and gas) from the associated a production zone. In other cases, the wellbore may be open hole, i.e. no casing. One or more inflow control devices are placed in the wellbore to control the flow of fluids into the wellbore. These flow control devices and production zones are generally separated by packers installed between them. Fluid from each production zone entering the wellbore is drawn into a tubular that runs to the surface. It is desirable to have a substantially even flow of fluid along the production zone. It is also desirable adjust the flow control devices so that unwanted fluids, such as water or gas, are not produced or produced in reduced amounts from the affected zones.

Horizontal wellbores often are completed with several inflow control devices placed spaced apart along the length of the horizontal section. Formation fluid often contains a layer of oil, a layer of water below the oil and a layer of gas above the oil. The horizontal wellbore is typically placed above the water layer. The boundary layers of oil, water and gas may not be even along the entire length of the horizontal well. Also, certain properties of the formation, such as porosity and permeability, may not be the same along the length of the well. Therefore, oil between the formation and the wellbore may not flow evenly through the various inflow control devices. For production wellbores, it is desirable to have a relatively even flow of the oil into the wellbore and also to inhibit the flow of water and gas through each inflow control device. Passive inflow control devices are commonly used to control flow into the wellbore. Such inflow control devices are set at the surface for a specific flow rate and then installed in the production string, which is then conveyed and installed in the wellbore. Such pre-set passive flow control devices are not designed or configured for downhole adjustments. After the well has been in production, a wireline tool is periodically conveyed into the production string to determine one or more properties of the fluid, wellbore or the formation. If it is determined that the flow of the fluid from particular flow control devices needs adjustment, such as because a particular zone has started producing an undesirable fluid, such as water or gas, or the inflow control device has clogged or deteriorated and the current setting is not adequate, etc. To change the flow rate through such passive inflow control devices, the production string is pulled out to adjust or replace the flow control devices. Such methods are very expensive and time consuming.

The disclosure herein provides improved apparatus and methods for determining one or more properties of interest downhole and adjusting flow control devices without removing the production string from the wellbore.

DETAILED DESCRIPTION OF THE DISCLOSURE

The present disclosure relates to apparatus and methods for controlling flow of formation fluids in a well. The present disclosure provides certain exemplary drawings to describe certain embodiments of the apparatus and methods that are to be considered exemplification of the principles described herein and are not intended to limit the concepts and disclosure to the illustrated and described embodiments.

FIG. 1 is a schematic diagram of an exemplary production wellbore system 100 that includes a wellbore 110 drilled through an earth formation 112 and into a production zone or reservoir 116. The wellbore 110 is shown lined with a casing 113 having a number of perforations 118 that penetrate and extend into the formations production zone 116 so that production fluids may flow from the production zone 116 into the wellbore 110. The exemplary wellbore 110 is shown to include a vertical section 110a and a substantially horizontal section 110b. The wellbore 110 includes a production string (or production assembly) 120 that includes a tubing (also referred to as the base pipe) 122 that extends downwardly from a wellhead 124 at the surface 126. The production string 120 defines an internal axial bore 128 along its length. An annulus 130 is defined between the production string 120 and the wellbore casing 113. The production string 120 is shown to include a generally horizontal portion 132 that extends along the deviated leg or section 110b of the wellbore 110. Production devices 134 are positioned at selected locations along the production string 120. Optionally, each production device 134 may be isolated within the wellbore 110 by a pair of packer devices 136. Although only two production devices 134 are shown along the horizontal portion 132, any number of such production devices 134 may be arranged along the horizontal portion 132.

Each production device 134 includes a downhole-adjustable flow control device 138 made according to one embodiment of the disclosure to govern one or more aspects of flow of one or more fluids from the production zones into the production string 120. The downhole-adjustable flow control device 138 may have a number of alternative structural features that provide selective operation and controlled fluid flow therethrough. In one embodiment, the downhole-adjustable flow control device 138 is adjustable by compliant tool or device conveyed from the surface. In another aspect, the downhole-adjustable flow control devices 138 are passive flow control devices (i.e., devices that are adjustable from the surface. In another aspect, each flow control device 138 may include a fluid control device (such as an inflow control device) 138a having a flow-through section or region and a setting device or tool 138b configured to adjust the flow through region when it is operated by tool from inside the flow control device. As used herein, the term “fluid” or “fluids” includes liquids, gases, hydrocarbons, multi-phase fluids, mixtures of two of more fluids, water and fluids injected from the surface, such as water. Additionally, references to water should be construed to also include water-based fluids; e.g., brine or salt water.

FIG. 1 further shows a tool 150 conveyed into the wellbore from the surface location via a suitable conveying member 155, such as a wireline or a tubular (such as a slick line or a coiled tubing). The tool 150 included one or more sensors 152 for providing measurements relating to one or more properties or parameters of interest and a latching device 154 for adjusting the flow from the flow control device 138. The property of interest may include any desired property, including, but not limited to, flow rate, pressure, temperature, and water or gas content in the fluid. Any suitable sensor may be used to determine the properties of interest, including, but not limited to a flow meter, pressure sensor, temperature sensor, resistivity sensor, acoustic sensor, and nuclear magnetic resonance sensor. Such sensors are known in the art and are thus not described in detail herein. The tool 150 may further include a controller or control unit 170 that includes a processor 172, such as a microprocessor, a memory or data storage device 174, such as a solid state memory, programs and algorithms 176 accessible to the processor 170 for executing programmed instructions. A telemetry unit 180 provides two-way communication between the downhole tool 150 and a surface controller or control unit 190 via a communication link 156. Power to the downhole tool is provided via a suitable cable in the conveying member 155. The surface controller may be a computer-based unit and may include a processor 192, a data storage device 194 and programmed instruction, models and algorithms 196 accessible to the processor. Other peripherals, such as data entry device, display device etc. 198 may be utilized for operating the controller unit 190. The controller 190 may communicate with a remote unit or satellite unit 199, such as placed at an office.

The latching device 154 may be any device configured to be move inside the flow control device 138 to couple to the setting device or member 138b of the flow control device 138. In one aspect, the latching device 154 may include a coupling element 154a configured to couple to a coupling element 138c of the setting device 138b. The latching device 154 may be moved in the flow control device 138 to move the coupling element 138c to adjust the flow through the flow control device 138. Certain exemplary flow control devices and tools are described below in reference to FIGS. 2-6. It should be noted that any downhole-adjustable flow control device and any suitable conveyable tool configured to adjust the downhole-adjustable device may be used for controlling flow of the fluid through the flow control device for the purposes of this disclosure.

In operation, the tool 150 is conveyed into the base pipe 122 and by the conveying member 155 and located proximate a flow control device 138. Surface equipment, such as depth locators and downhole sensors 152, such as accelerometers, magnetometers, etc. may be utilized to locate the tool 150 at the desired well depth. The sensors 152 are then activated to determine one or more properties (or parameters) of interest, such a flow rate, water cut, pressure, oil/water ratio, gas/oil ratio, presence of corrosion or asphaltene, water breakthrough, quality of cement bond, health of device or a component in the well, etc. The controllers 170/190 process the sensor data and provide information about one or more desired properties of interest in-situ (i.e., in real time). If the one or more parameters do not meet a selected criteria, such as water production is above a desired flow rate or volume, the operator or the system 100 positions the latching device or tool 154 and causes it to couple to the setting device 138b. The tool is then operated or maneuvered to operate the setting device to adjust the flow of the fluid through the flow control device 138 to a desired level. The above procedure may be utilized to determine a property of interest for each flow control devices and adjusted accordingly, without tripping the tool 150 from the wellbore. Thus, the system 100 enables determination of any number of properties downhole and setting of the one or more flow control devices without tripping the tool from the wellbore.

FIG. 2 shows an isometric view of an embodiment of a portion of an exemplary multi-channel inflow control device 200 that may be used in the drill string and wellbore described herein. The inflow control device 200 may be included in a downhole-adjustable flow control device 138 for controlling the flow of fluids from a reservoir into a production string. The production device 134 may include a filtration device for reducing the amount and size of particulates entrained in the fluids and the inflow control device 200 that controls the overall drainage rate of the formation fluid into the wellbore. As depicted, the inflow control device 200 is shown to include a number of structural flow sections 220a, 220b, 220c and 220d formed around a tubular member 202, each such section defining a flow channel or flow path. Each section may be configured to create a predetermined pressure drop to control a flow rate of the production fluid from the formation into the wellbore tubing. One or more of these flow paths or sections may be occluded or independent (not in hydraulic communication with another section) in order to provide a selected or specified pressure drop across such sections. Fluid flow through a particular section may be controlled by closing ports 238 provided for the selected flow section.

As discussed below, a tubular member may adjoin the ports and thereby expose one or more selected ports, depending on parameters and conditions of the surrounding formation. As depicted, the total pressure drop across the inflow control device 200 is the sum of the pressure drops created by each active section. Structural flow sections 220a-220d may also be referred to as flow channels or flow-through regions. To simplify description of the inflow control device 200, the flow control through each channel is described in reference to channel 220a. Channel 220a is shown to include an inflow region 210 and an outflow region or area 212. Formation fluid enters the channel 220a into the inflow region 210 and exits the channel via outflow region 212. Channel 220a creates a pressure drop by channeling the flowing fluid through a flow-through region 230, which may include one or more flow stages or conduits, such as stages 232a, 232b, 232c and 232d. Each section may include any desired number of stages. Also, in aspects, each channel in the inflow control device 200 may include a different number of stages. In another aspect, each channel or stage may be configured to provide an independent flow path between the inflow region and the outflow region. Some or all of channels 220a-220d may be substantially hydraulically isolated from one another. That is, the flow across the channels and through the device 200 may be considered in parallel rather than in series. Thus, a production device 134 may enable flow across a selected channel while partially or totally blocking flow in the other channels. The inflow control device 200 blocks one or more channels without substantially affecting the flow across another channel. It should be understood that the term “parallel” is used in the functional sense rather than to suggest a particular structure or physical configuration.

Still referring to FIG. 2, there are shown further details of the multi-channel flow member 200 which creates a pressure drop by conveying the in-flowing fluid through one or more of the plurality of channels 220a-220d. Each of the channels 220a-220d may be formed along a wall of a base tubular or mandrel 202 and include structural features configured to control flow in a predetermined manner. While not required, the channels 220a-220d may be aligned in a parallel fashion and longitudinally along the long axis of the mandrel 202. Each channel may have one end in fluid communication with the wellbore tubular flow bore (shown in FIGS. 3-8) and a second end in fluid communication with the annular space or annulus separating the flow control device 200 and the formation. Generally, channels 220a-220d may be separated from one another, for example in the region between their respective inflow and outflow regions.

In embodiments, the channel 220a may be arranged as a maze or labyrinth structure that forms a tortuous or circuitous flow path for the fluid flowing therethrough. In one embodiment, each stage 232a-232d of channel 222a may respectively include a chamber 242a-242d. Openings 244a-244d hydraulically connect chambers 242a-242d in a serial fashion. In the exemplary configuration of channel 220a, formation fluid enters into the inflow region 210 and discharges into the first chamber 242a via port or opening 244a. The fluid then travels along a tortuous path 252a and discharges into the second chamber 242b via port 244b and so on. Each of the ports 244a-244d exhibit a certain pressure drop across the port that is function of the configuration of the chambers on each side of the port, the offset between the ports associated therewith and the size of each port. The stage configuration and structure within determines the tortuosity and friction of the fluid flow in each particular chamber, as described herein. Different stages in a particular channel may be configured to provide different pressure drops. The chambers may be configured in any desired configuration based on the principles, methods and other embodiments described herein. In embodiments, the multi-channel flow member 200 may provide a plurality of flow paths from the formation into the tubular.

As discussed below, a downhole-adjustable flow control device may be configured to enable adjustment of the flow path through the multi-channel flow member, thereby customizing the device based on formation and fluid flow characteristics. The channel or flow path may be selected based on formation fluid content or other measured parameters. In one aspect, each stage in the inflow control device 200 may have same physical dimensions. In another aspect, the radial distance, port offset and port size may be chosen to provide a desired tortuosity so that the pressure drop will be a function of the fluid viscosity or density. In an embodiment, a multi-channel flow member may exhibit relatively high percentage pressure drop change for low viscosity fluid (up to about 10 cP) and a substantially constant pressure drop for fluids in relatively higher viscosity range (from about 10 cP to 180 cP). Although the inflow control device 200 is described as a multi-channel device, the inflow control device used in a downhole-adjustable flow control device may include any suitable device, including, but not limited to, orifice-type device, helical device and a hybrid device.

FIG. 3A is an isometric view of a downhole-adjustable flow control device 300 over a tubular member 302 according to one embodiment of the disclosure. FIG. 3B is a sectional view of the tubular 302 and adjustable flow control device 302. FIGS. 3A and 3B depict the adjustable flow control device 300 in a first position, which position for example may be set before deploying the flow control device 300 in the wellbore. The flow control device 300 is shown to include a multi-channel flow member 304 (also referred to inflow control device) and setting device 305. The first position of the setting device 305 corresponds to a selected channel of the multi-channel flow member 304. In an aspect, the multi-channel flow member 304 includes a plurality of flow channels, wherein each of the channels has a different flow resistance. In one embodiment the flow resistance for each channel may be configured to restrict a flow of a selected fluid, such as gas or water, into the tubular 302. As depicted, the multi-channel flow member 304 is configured to enable fluid flow through a channel that includes a series of stages 306, a flow port 307 and tubular 302. In aspects, the flow port 307 is located on a grooved portion 309 of the tubular 302, thereby enabling fluid flow from all ports 307, whether covered or uncovered by rotationally indexed member 308. In an aspect, four flow ports are located circumferentially, at 90 degrees relative to one another, around the grooved portion 309. Rotationally indexed member 308 includes a recessed portion 310 which exposes the flow port 307. The rotationally indexed member 308 includes a track 312 (also referred to as a J-slot or guide track) and a pin 314 (also referred to as a J-pin or guide pin) that control the rotational movement of the rotationally indexed member 308. In an aspect, there may be a plurality of pins 314 positioned with the track 312 to ensure stability during movement of the rotationally indexed member 308. In aspects, the track 312 is a patterned opening in the member that enables rotational and axial movement to adjust flow of fluid through the flow control device 302. In an embodiment, axial movement of components located inside of the tubular 302 may adjust the rotationally indexed member 308 to cause fluid flow through a selected channel of the multi-channel flow member 304.

The setting device 305 includes the rotationally indexed member 308, biasing member 320 and guide sleeve 316, each located outside of tubular 302. The guide sleeve 316 is coupled to the rotationally indexed member 308, which enables axial movement 317 of the tubular 302 and sleeve 316, while allowing independent rotational movement of the components. The guide sleeve 316 is also coupled to biasing member 320, such as a spring, that resists axial movement 317 when compressed. In an aspect, the biasing member 320 is fixedly secured to the tubular 302 on the end opposite the guide sleeve. In the depicted embodiment, the guide sleeve 316 is coupled to a guide pin 322 located in a slot. The guide pin 322 controls the axial range of motion of the guide sleeve 316 and the biasing member 320. An inner member (also referred to as a coupling member, a latching device or coupling tool), such as a collet 324, is located within the tubular 300 and includes protrusions 326 configured to selectively engage a shifting sleeve 328 that is a part of or coupled to the guide sleeve 316. The shifting sleeve 328 may also be referred to as a coupling member. As discussed below in FIGS. 4A and 4B, the protrusions 326 may engage the shifting sleeve 328 when the collet 324 moves axially in direction 317 within the tubular 300. The collet 324 may be any suitable member or tool configured to move axially within the tubular 300 and cause movement of the adjustable flow control device 302. The collet 324 includes axial members 332 separated by slots, wherein the axial members 332 are configured to bias or press away from the tubular axis and against the inner surface of the tubular 302. Accordingly, a wireline tool or coiled tubing may be used to move the collet 324 axially 317 within the tubular 302. The collet 324 may selectively engage and disengage to components within the tubular 302 to cause movement of the rotationally indexed member 308 and other components of the adjustable flow control device 300.

FIGS. 4A and 4B show a side view and a sectional view, respectively, of the tubular 302 and adjustable flow control device 300 in transition between channel flow positions. In aspects, the adjustable flow control device 300 may have any number of flow positions. As depicted, the adjustable flow control device 300 is in transition between the position in FIGS. 3A and 3B and the position in FIGS. 5A and 5B. In an aspect, a wireline tool or slickline tool may be used to moves the collet 324 in direction 317, wherein the collet 324 engages the shifting sleeve 328. Upon engaging the inner portion the shifting sleeve 328, the collet 324 causes the biasing member 320 to compress and the rotationally indexed member 308 to move in the direction 317. As the rotationally indexed member 308 moves in direction 330, the track 312 moves about pin 314 to cause the member to move rotationally. As depicted, the pin is in position 400 of the track 312 and the rotationally indexed member 308 is in transition between the first position and the second position, where the pin 314 is located in positions 402 and 404, respectively. The collet protrusions 326 may remain engaged with the shifting sleeve 328 until the protrusions 326 are pressed axially (318) and inward, such as by a release sleeve 406 located on the inside of the tubular 300.

After releasing the protrusions 326 from shifting sleeve 328, the wireline tool continues to move the collet 324 downhole in the direction 330. Releasing the collet 324 causes expansion of the biasing member 320, causing the rotationally indexed member 308 and guide sleeve 316 to move in direction 408 in to the second position. The second position causes fluid flow through a second channel of the multi-channel flow member 304 while the pin 314 is in position 404 of the track 312. FIGS. 5A and 5B show a side view and sectional view respectively of the adjustable flow control device 300 in the second position. As depicted, the adjustable flow control device 300 enables fluid flow through the channel 500 of the multi-channel flow control member in the second position. Accordingly, the rotationally indexed member 308 is rotated to prevent fluid flow through other flow channels, including channel 502. The biasing member 320 is fully expanded, thereby pressing the guide pin 322 to a limit of the pin slot. As the collet 324 moves in direction 330 and releases the shifting sleeve 328, the pin 314 of the rotationally indexed member 308 moves into position 404 of track 312. The recessed portion 310 of the member 308 is then aligned to enable fluid flow from the channel 500 into the flow port 307.

FIGS. 3A through 5B show the movement of the adjustable flow control device 300 between two positions, wherein each position causes the formation fluid to flow through a different channel of the multi-channel flow member 304 and into the tubular 302. In aspects, the multi-channel flow member 304 includes a plurality of channels configured to enable selected fluids to flow into the tubular 302 while restricting flow of other fluids. A wireline tool or other suitable device may be used to move the inner member or collet 324 within the tubular 302 to cause adjustment of the adjustable flow control device 302. The process shown in FIGS. 3A through 5B may be repeated as many times as desired to set the adjustable flow control device 300 to a selected position.

In another embodiment, an electromagnetic and/or electrical mechanical device may be used to adjust the position of a flow control device, wherein a wireline or slickline may communicate command signals and power to control the fluid flow into the tubular. FIG. 6A is a sectional view of an embodiment of a tubular 602 and adjustable flow control device 600 in a first position. As depicted, the adjustable flow control device 600 is shown prior to shifting or adjusting the flow path into the tubular 602. The adjustable flow control device 600 includes a multi-channel flow member 604 that contains a series of stages 606. The stages 606 enable flow of fluids through a flow port 607 into the tubular 602. In an embodiment, a plurality of flow ports 607 are positioned circumferentially about the tubular 600. A setting device 605 includes a rotationally indexed member 608 with a recessed portion 610 that selectively exposes one the flow ports 607. The rotationally indexed member 608 includes a track 612 and pin 614 that cooperatively control movement of the rotationally indexed member 608. In an aspect a plurality of pins 614 may be positioned within the track 612 to ensure stability during rotational movement. In aspects, the track 612 is a patterned opening in the member that enables rotational and axial movement to adjust flow of fluid through the adjustable flow control device 600.

The setting device 605 also includes a biasing member 620 and guide sleeve 616, each located outside of tubular 602. The guide sleeve 616 is coupled to the rotationally indexed member 608 for axial movement 617 as well as independent rotational movement of the components relative to one another. A magnetic member 618 is positioned in the guide sleeve 616 to enable a magnetic coupling to components inside the tubular 602. In one aspect, a plurality of magnetic members 618 may be circumferentially positioned in the sleeve 616. As illustrated, the guide sleeve 616 is also coupled to a biasing member 620, such as a spring, that resists axial movement 617 when compressed. The biasing member 620 is secured to the tubular 602 on the end opposite the guide sleeve 616. As shown, the pin 614 is positioned near a first end of the track 612 (or downhole axial extremity). In other aspects, the guide sleeve 616 may be metallic or magnetized, thereby providing a coupling force for a magnet inside the tubular 600.

An intervention string 622 may be used to convey a magnet assembly 624 downhole within the tubular 600. The magnet assembly 624 may include a suitable electromagnet configured to use electric current to generate a magnetic field. The magnet assembly 624 may generate a magnetic field to cause a coupling with the metallic member(s) 618. Current is supplied to the magnet assembly 624 by a suitable power source 626, which may be positioned in, on or adjacent to a wireline or coil tubing. The magnet assembly 624 may be selectively powered as the intervention string 622 travels axially in the direction 617 within the tubular 600 to cause movement of the guide sleeve 616. For example, the magnetic assembly 624 may generate a magnetic field to enable a coupling to the magnetic member(s) 618 as the string 622 moves axially 617 downhole, thereby causing the guide sleeve 616 to move axially 617. The magnetic coupling between the magnet assembly 624 and the magnetic members 618 is of a sufficient strength to maintain the coupling to overcome the spring force of biasing member 620 as the guide sleeve 616 moves axially 617. In an aspect, the metallic member(s) 614 may be a magnet to provide sufficient force in a coupling between the member and magnet assembly 624. The magnet assembly 624 may include a plurality of electromagnets spaced circumferentially about the assembly, wherein each electromagnet is configured to couple to a corresponding metallic member 614. As depicted, the wireline components and magnet assembly 624 may be used to move the guide sleeve 616 and rotationally indexed member 608 axially 617. Further, the axial 617 movement of the magnet assembly 624, while magnetically coupled to the guide sleeve 616, causes rotational movement of the rotationally indexed member 608, thereby adjusting the flow path through the multi-channel flow member 604.

It should be noted that the components positioned outside of tubular 602 (FIGS. 6A-6C), including the adjustable flow control device 600, are substantially similar to those shown in FIGS. 3A-5B. Specifically, in aspects, the illustration of FIGS. 6A, 6B and 6C correspond to that of FIGS. 3A, 4A and 5A. The illustrated mechanisms show different devices or tools located inside the tubular to adjust the adjustable flow control devices. In other embodiments, the components, including the multi-channel flow member 604 and rotationally indexed member 608, may include different application-specific configurations and components depending on cost, performance and other considerations. In addition, the power source 626 may also include one or more sensor packages, including but not limited to, sensors for making measurements relating to flow rate, fluid composition, fluid density, temperature, pressure, water cut, oil-gas ratio and vibration. In an embodiment, the measurements are processed by a processor using a program and a memory, and may utilize selected parameters based on the measurements to alter the position and flow through the adjustable flow control device 602.

FIG. 6B is a sectional view of the tubular 602 and adjustable flow control device 600, as shown in FIG. 6A, in a second position. As shown, the biasing member 620 is compressed between the guide sleeve 616 and the tubular 600. Relative to the position in FIG. 6A, the rotationally indexed member 608 has shifted axially 617 in a downhole direction, wherein the pin 614 is positioned near a second end of the track 612 (or uphole axial extremity). The rotationally indexed member 608 rotates while moving axially between the first position (FIG. 6A) and second position (FIG. 6B). As depicted, the magnetic assembly 624 is coupled to the metallic members 618. The magnetic coupling provides a force in direction 617 that overcomes the spring force of the biasing member 620 to compress the member. The adjustable flow control device 600 is shown in the process of adjusting the flow path into the tubular 602. In an aspect, the second illustrated position is approximately halfway between a first flow channel position (position one, FIG. 6A) and a second flow channel position (position three, FIG. 6C below).

FIG. 6C, a sectional view of the tubular 602 and adjustable flow control device 600 that shows the adjustable flow control device of FIGS. 6A and 6B, in a third position. The magnet assembly 624 is disabled, thereby removing the magnetic field and decoupling the assembly from the metallic members 618. Accordingly, the guide sleeve 616 retracts in direction 630, as it is pushed by the force of biasing member 620. As the rotationally indexed member 608 shifts axially 630 in an uphole direction, the pin 614 is positioned near the first end of the track 612 (or downhole axial extremity). As shown, the rotationally indexed member 608 and the adjustable flow control device 600 is in a second flow channel position, thereby exposing flow port 607 in recessed portion 610 (not shown). In an aspect, four flow channels or paths are provided in multi-channel flow member 604, wherein a selected channel may be in fluid communication with one or more flow ports 607 in the tubular 602. Accordingly, the positions illustrated in FIGS. 6A-6C show the adjustable flow control device 600 shifting from a first flow channel position to a second flow channel position. In an embodiment, the first flow channel position of FIG. 6A corresponds to the position shown in FIG. 3A. Further, the second flow channel position of FIG. 6C may correspond to the position shown in FIG. 5A. The illustrated magnetic assembly 624 provides an apparatus for adjusting fluid flow into the tubular 602 locally, using a processor and program, or by a remote user, wherein the apparatus includes fewer moving parts. The processor and/or program may be located downhole or at the surface, depending on application needs and other constraints.

It should be understood that FIGS. 1-6C are intended to be merely illustrative of the teachings of the principles and methods described herein and which principles and methods may applied to design, construct and/or utilizes inflow control devices. Furthermore, foregoing description is directed to particular embodiments of the present disclosure for the purpose of illustration and explanation. It will be apparent, however, to one skilled in the art that many modifications and changes to the embodiment set forth above are possible without departing from the scope of the disclosure.
