Abstract
Description
- Production of hydrocarbons from loose, unconsolidated, and/or fractured formations often produces large volumes of particulates along with the formation fluids. These particulates can cause a variety of problems. For this reason, operators use gravel packing as a common technique for controlling the production of such particulates.
- To gravel pack a completion, a screen is lowered on a workstring into the wellbore and is placed adjacent the subterranean formation. Particulate material, collectively referred to as "gravel," and a carrier fluid, is pumped as slurry down the workstring. Eventually, the slurry exits through a "cross-over" into the wellbore annulus formed between the screen and the wellbore.
- The carrier fluid in the slurry normally flows into the formation and/or through the screen. However, the screen is sized so that gravel is prevented from flowing through the screen. This results in the gravel being deposited or "screened out" in the annulus between the screen and the wellbore to form a gravel-pack around the screen. Moreover, the gravel is sized so that it forms a permeable mass that allows produced fluids to flow through the mass and into the screen but blocks the flow of particulates into the screen.
- Due to poor distribution of the gravel, it is often difficult to completely pack the entire length of the wellbore annulus around the screen. This can result in an interval within the annulus that is not completely gravel packed. The poor distribution of gravel is often caused by the carrier liquid in the slurry being lost to more permeable portions of the formation. Due to the loss of the carrier liquid however, the gravel in the slurry forms "sand bridges" in the annulus before all of the gravel has been placed around the screen.
- Such bridges block further flow of the slurry through the annulus, thereby preventing the placement of sufficient gravel below the bridge in top-to-bottom packing operations or above the bridge in bottom-to-top packing operations. Alternate flow conduits, called shunt tubes, can alleviate this bridging problem by providing a flow path for the slurry around such sand bridges. The shunt tubes are typically run along the length of the screen and are attached to the screen by welds.

Figures 1A-1B illustrate example schematic views ofsand screens 18a-b provided withshunt tubes 30a-b in awellscreen assembly 10.Figure 2A illustrates an example exploded view of thewellscreen assembly 10 components used in an open hole. Also,Figure 2B illustrates an example alternative exploded view ofwellscreen assembly 10 components used in a cased hole. - As shown in the
assembly 10, a firstsand control device 12a is coupled to a secondsand control device 12b, and eachdevice 12a-b hasbasepipe joints 14 joined together to define aproduction bore 16.Screens 18a-b having filter media surround thebasepipe joints 14 and are supported byribs 19. Theassembly 10 is provided withshunt tubes 30a-b, which are typically steel tubes and have a substantially rectangular cross-section. Theshunt tubes 30a-b are supported on the exterior of thescreens 18a-b and provide analternate flow path 32 to the main production bore 16. - To provide fluid communication between the adjacent
sand control devices 12a-b,jumper tubes 40 are disposed between theshunt tubes 30a-b. In this way, theshunt tubes 30a-b and thejumper tubes 40 maintain theflow path 32 outside the length of theassembly 10, even if the borehole's annular space B is bridged, for example, by a loss of integrity in a part of the formation F. Additional examples of shunt tube arrangements can be found inU.S. Pat. Nos. 4,945,991 and5,113,935 . The shunt tubes may also be internal to the filter media, as described inU.S. Pat. Nos. 5,515,915 and6,227,303 . - As shown in
Figures 1A-1B and2A , the assembly for an open hole completion typically hasmain shrouds 28a-b that extend completely over thesand control devices 12a-b and provide a protective sleeve for the filter media andshunt tubes 30a-b. Theshrouds 28a-b have apertures to allow for fluid flow. Themain shrouds 28a-b terminate at theend rings 20a-b, which support the ends of theshrouds 28a-b and have passages for the ends of theshunt tubes 30a-b. For a cased hole completion, theassembly 10 as shown inFigure 2B may lack a shroud. - In either design, the
shunt tubes 30a-b stop a certain length from the ends of thesand control devices 12a-b to allow handling room when thedevices 12a-b are joined together at the rig. Once thedevices 12a-b are joined however, theirrespective shunt tubes 30a-b are linearly aligned, forming a gap between them. Therefore, continuity of the shunt tubes'flow path 32 is typically established by installing the short, pre-sizedjumper tubes 40 in the gap. - Each
jumper tube 40 has aconnector 50 at each end that contains a set of seals and is designed to slide onto the end of thejumper tube 40 in a telescoping engagement. When thejumper tube 40 is installed into the gap between theshunt tubes 30a-b, theconnector 50 is driven partially off the end of thejumper tube 40 and onto the end of theshunt tube 30a-b until theconnector 50 is in a sealing engagement with bothshunt tubes 30a-b and thejumper tube 40. - The shunt tubes'
flow path 32 is established once bothconnectors 50 are in place. Moreover, a series of set screws (not shown) have been used to engage both thejumper tube 40 and adjoiningshunt tube 30a-b. The screws are driven against the tube surfaces, providing a friction lock to secure theconnector 50 in place. - However, this connection is not very secure, and there is concern that debris or protruding surfaces of the wellbore can dislodge the
connectors 50 from sealing engagement with thetubes 30a-b and 40 while running thewellscreen assembly 10 into the wellbore. Therefore, a device called asplit cover 22 as shown inFigure 1A is typically used to protect theconnectors 50. - The
split cover 22 is a piece of thin-gauge perforated tube, essentially the same diameter as thescreen assembly 10, and the same length as the gap covered by thejumper tubes 40. Theperforated cover 22 is split into halves with longitudinal cuts, and the halves are rejoined with hinges along one seam and locking nut and bolt arrangements along the other seam. Thesplit cover 22 can be opened, wrapped around the gap area between thesand control devices 12a-b, and then closed and secured with the locking bolts. - Other ways of connecting shunt tubes on adjoining sand control devices are also known in the art. For example,
U.S. Pat. No. 6,409,219 to Broome et al. describes a system wherein shunts on adjacent sand control devices are aligned when the correct torque is applied to join the devices. Alignment marks are included on the devices to indicate when the correct torque has been applied. - Further,
U.S. Pat. No. 5,341,880 to Thorstensen et al. describes a sand screen structure assembled from a plurality of generally tubular filter sections that are axially snapped together in a manner facilitating the simultaneous interconnection of circumferentially spaced axially extending shunt tubes secured to and passing internally through each of the filter sections. In an alternate embodiment of the sand screen structure, the shunt tubes are secured within external side surface recesses of the filter section bodies. -
U.S. Pat. No. 5,868,200 to Bryant et al. describes an alternate-path wellscreen that is made-up of joints. The screen has a sleeve positioned between the ends of adjacent joints. The sleeve acts as a manifold for fluidly-connecting the alternate-paths on one joint with the alternate-paths on an adjacent joint. - Another connector is disclosed in
U.S. Pat. 7,497,267 , which is incorporated herein by reference.Figures 3A-3B show examples ofconnections 100a-b disclosed therein. Theconnections 100a-b secure ajumper tube 40 to ashunt tube 30. In general, theconnections 100a-b are designed to slide onto the end of thejumper tube 40 in a telescoping engagement. When thejumper tube 40 is installed into the gap between theshunt tubes 30, theconnections 100a-b are driven partially off of the end of thejumper tube 40 and onto the end of theshunt tube 30 to form a sealing engagement between bothtubes connectors 100a-b in place. - For example,
Figure 3A shows aconnection 100a having aconnector 108 and aconnector lock 102 disposed on ajumper tube 40. Thejumper tube 40 haslugs 104 affixed to its sides. Theconnector 108 is pushed forward to engage ashunt tube 30 secured to theend ring 20. Theconnector lock 102 is the secured in place by screwing thescrews 106 in thelock 102 to keep thelugs 104 in the side slots in thelock 102. Thelugs 104 andscrews 106 secure thelock 102 in the position to hold theconnector 108 in the engaged position. - In another example,
Figure 3B shows aconnection 100b having aconnector 110 disposed on ajumper tube 40. A "C"-shapedreceiver 112 is affixed to theshunt tube 30 and is positioned with the open side of the "C" toward the end of thetube 30. Theconnector 110 is moved to engage theshunt tube 30 so that the end of theconnector 110 fits in thereceiver 112. Theconnector 110 is attached to thejumper tube 40 withset screws 116, andother set screws 114 on thereceiver 112 align with mating holes (not apparent in this view) inconnector 110 to affix thetubes - Currently, the STT (Shunt Tube Technology) jumper assembly needs to be set with set screws (e.g., eight set screws may need to be individually fixed) and typically requires more than one person to install. Moreover, different tools are needed in order to fix the set screws of the jumper assembly into position. As a result, more preparation time is needed to run screens downhole, at times limiting screen installation and production to only five screens per hour.
- Therefore, although the above-techniques for connecting shunt tubes on adjoining joints of a wellscreen assembly may be effective, operators seek more efficient and reliable ways to make these connections at the rig during deployment of the assembly.
- The subject matter of the present disclosure is directed to overcoming, or at least reducing the effects of, one or more of the problems set forth above.
- A method and apparatus for communicating ends of adjoining shunt tubes on connected wellscreen joints is provided. The method involves positioning a jumper tube in a gap between the opposed ends of the adjoining shunt tubes on the connected wellscreen joints and connecting first and second ends of the jumper tube to the opposed ends of the adjoining shunt tubes. To connect the first and second ends, the method involves moving a first connector from a retracted position on the first end into an extended position at least partially over the opposed end of the shunt tube and engaging first thread between a first inner surface of the first connector and a first outer surface of the opposed end of the shunt tube.
- It may be further possible to disengage the first thread by rotating and moving the first connector from the extended position into the retracted position away from the opposed end.
- In a further embodiment, connecting the first and second ends can further involve moving a second connector from a retracted position on the second end into an extended position at least partially over the opposed end of the shunt tube and engaging second thread between a second inner surface of the second connector and a second outer surface of the opposed end of the shunt tube.
- In one embodiment, a connection is used for communicating opposed ends of adjoining shunt tubes on connected wellscreen joints. The connection has a jumper tube having first and second ends. A first connector is disposed on the first end and is movable thereon at least from a retracted position to an extended position. The first connector in the extending position positions at least partially over the opposed end of the shunt tube. A first thread is disposed on a first inner surface of the first connector. The first thread on the first connector in the extended condition engages a first outer surface of the opposed end of the shunt tube.
- The first connector can be movable from the extended position to the retracted position, and the first thread can be rotated with the moving first connector to disengage the first inner surface from the first outer surface of the opposed end.
- In a further embodiment, the connection can have a second connector disposed on the second end and movable thereon at least from a retracted position to an extended position. The second connector in the extending position positions at least partially over the opposed end of the shunt tube. A second thread is disposed on a second inner surface of the second connector, and the second thread on the second connector in the extended condition engages a second outer surface of the opposed end of the shunt tube.
- To move the first connector from the retracted position at least partially over the opposed end, the first connector can slide over the opposed end in one direction while locking ratchet threading of the first thread in an opposite direction. A first ratchet portion of the first thread can engage a second ratchet portion of the first thread on the first outer surface of the opposed end and can engage a third ratchet portion of the first thread on another outer surface of the first end of the jumper tube. Alternatively, a portion of the first inner surface of the first connector can engage a portion of the first outer surface of the first end with an interference fit.
- In an additional embodiment, a wellscreen assembly has first and second screen joints connected together and having first and second adjoining shunt tubes. The first and second adjoining shunt tubes having opposed ends separated by a gap from one another. The assembly further includes the jumper tube with at least the first connector.
- The foregoing summary is not intended to summarize each potential embodiment or every aspect of the present disclosure.

Fig. 7 illustrates an end view of the disclosed jumper tube connector according to the present disclosure. -
Fig. 8 illustrates a jumper tube having using one fixed end and one sliding connector according to the present disclosure. - Examples of a wellscreen assembly according to the present disclosure include basepipe joints and screen sections attached to the outer surface of the basepipe joints. The assembly also features shunt tubes attached to the basepipe joints via top and bottom end rings. The shunt tubes can be attached to the screen sections via these rings and may be transport tubes or packing tubes for gravel packing operations or the like. Examples of the present disclosure provide connections for securing a jumper tube to adjoining shunt tubes of adjoining joints of the wellscreen assembly, which may be used in open or cased holes.
- The examples provided in the present disclosure allow the jumper tube to be set by one person and without any additional tools. As a result, the requirement or need for using set screws, which currently need to be set manually, is alleviated. This leads to an ease in setting and installing the jumper tube (i.e., one operator may only be needed), which can increase the rate at which wellscreens can be run in hole. Furthermore, the disclosed jumper tube connector can have a cylindrical shape, which leads to higher performance ratings and allows for longer completions.
- The connections of the present disclosure can be used in open-hole or cased-hole wellscreen assemblies. However, cased-hole assemblies may typically use centralizers disposed between wellscreen joints and may not use end rings at the various joints. As will be appreciated, the joints of the wellscreen assemblies have timed threads so that the various shunt tubes can be aligned with one another along the assembly as the joints are connected.
- Turning now to the examples illustrated in
Figures 4A and 4B , portion of awellscreen assembly 10 is shown having first andsecond wellscreen joints 14a-b connected by abasepipe connection 15. Each joint 14a-b has adjoiningshunt tubes 30a-b with opposed ends 35 that are separated from one another by a gap G. Although not shown, each joint 14a-b may have screens and other common components detailed previously. - As shown in
Figure 4A , in order to communicate theends 35 of the wellscreen assembly'sshunt tubes 30a-b with one another, ajumper tube 200 is installed within the gap G between each of the shunt tube ends 35. Then, as shown inFigure 4B , at least one slidingend connector 210a-b on at least oneend 205a-b of thejumper tube 200 affixes to at least one of the shunt tube ends 35. - Preferably, each
end 205a-b of thejumper tube 200 has a slidingend connector 210a-b as shown. Eachconnector 210a-b is movably disposed on eachend 205a-b of thejumper tube 200. However, an alternative arrangement may have a fixed end 205 on thejumper tube 200 that connects to one of the shunt tube ends 35 without aconnector 210 and instead by fitting on theend 35 with an interference fit, locking on with a ratchet thread, or connecting in a conventional manner. Either way, the opposite end 205 of thejumper tube 200 can have the slidingend connector 210 for first aligning with theshunt tube end 35 and then sliding onto theend 35, as discussed in more detail below. - As shown in
FIGS. 4A-4B , acenter expanse 202 of thejumper tube 200 may be of a rectangular, square, or other structural shape. Referring also to the end view of the disclosedjumper tube 200 andconnector 210 as shown inFig. 7 , the inside 206 of thecenter expanse 202 of thejumper tube 200 may have a rectangular or otherwise non-cylindrical shape. However, the slidingend connectors 210a-b that are movably disposed on theends 205a-b of thejumper tube 200 may be cylindrical with a circular diameter or may have a different structural shape (e.g., oval, hexagonal, etc.). - In one example, although the sliding
end connectors 210a-b may have a different shape and size than thecenter expanse 202 of thejumper tube 200, eachend 205a-b of thejumper tube 200 where the slidingend connector 210a-b is located may be a cylindrical tube having about the same cross-sectional area as thecenter expanse 202 of thejumper tube 200. Also, because the shape and size of the slidingend connectors 210a-b may differ from the shape and size of thecenter expanse 202, thejumper tube 200 may havetransitions 204 on each side of thecenter expanse 202 of thejumper tube 200 where the shape transitions from the rectangular cross-section of theexpanse 202 to the cylindrical cross-section of theends 205a-b. - The sliding
end connectors 210a-b can be movably disposed on the jumper tube ends 205a-b using an interference fit, using bearings, and/or using a sliding slot system that allows theconnectors 210a-b to move both, axially along the major axis (i.e., length) of thejumper tube 200, and rotationally, allowing theconnectors 210a-b to rotate about the circumference of the jumper tube's ends 205a-b. - The jumper tube ends 205a-b as shown act as an adapter between the
center expanse 202 of thejumper tube 200 and theconnectors 210a-b, and theends 205a-b are structurally compatible to match the shape and size of thecenter expanse 202 of thetube 200. - Now that the components of the
jumper tube 200 andwellscreen assembly 10 have been introduced, the engagement of thejumper tube 200 with the wellscreen assembly is now described. - As illustrated in
Figure 4A , operators assemble thejoints 14a-b together with thebasepipe connection 15. Bothjoints 14a-b typically haveend rings 20a-b already installed thereon, and theshunt tubes 30a-b may set in theslots 22 of the end rings 20a-b. When thejoints 14a-b are connected, the timed threads align the adjoiningshunt tubes 30a-b so that their ends 35 are spaced and aligned across from one another. An operator then positions thejumper tube 200 in the gap G with thejumper tube connectors 210a-b disengaged away from the shunt tube ends 35 in a retracted position on theends 205a-b of thejumper tube 200. - As shown in
Figure 4B , the operator then engages thejumper tube connectors 210a-b with theends 35 of theshunt tubes 30a-b. Briefly, theconnectors 210a-b engage with the shunt tube ends 35 when theconnectors 210a-b are slid into an extended position over a portion of the shunt tube ends 35 and locking features (e.g., threading) of theconnectors 210a-b lock with locking features (e.g., threading) on the shunt tube ends 35. - When slid to an engaged position (as shown in
Figure 4B and described below), for example, theconnectors 210a-b are moved in the direction of the shunt tube ends 35, until theconnectors 210a-b slide over theends 35 and have locked with the shunt tube ends 35 using the threading (not shown) within the inner surface of thejumper tube connectors 210a-b (not shown). - As shown in
Figure 4A , the shunt tube ends 35 may also have threading as illustrated on the ends 35. Therefore, when thejumper tube connectors 210a-b engage the shunt tube ends 35 their respective threading locks theconnectors 210a-b on theends 35 of theshunt tubes 30a-b. - The threading disposed internally inside the
connectors 210a-b and disposed externally on the shunt tube ends 35 may comprise different types of threads. In one example, the threads may allow the slidingend connector 210a-b to thread onto the shunt tube ends 35 in a conventional manner by rotating and twisting. Preferably, the threads comprise ratchet threading which theconnectors 210a-b use during engagement by being capable of sliding over the shunt tube ends 35 in one direction, while being ratchet locked into position in the opposite direction. In this way, rotating theend connectors 210a-b is not necessary to connect them to the shunt tube ends 35 because the sliding action is only needed to engage the ratchet threading. - If desired, the ratchet thread described above may also allow the
connectors 210a-b to disengage with the shunt tube ends 35. In one example, theconnectors 210a-b can retract from the shunt tube ends 35 by unthreading though rotating and twisting, thereby unlocking the ratchet threading from their locking engagement with each other. - In addition to the thread, additional locking features can be used to engage the
connectors 210a-b with the ends 35. For example, the locking features can include slots defined in the opposing shunt tube ends 35. In this example, the locking features within thejumper tube connectors 210a-b can include tabs or catches for locking within the slots. Alternatively, the locking features disposed on the shunt tube ends 35 can be catches biased toward a locking position, and the locking features within theconnectors 210a-b can be slots engaging the biased catches in the locking position. The above embodiments are not limited, as reverse and or other arrangements are also possible. - As illustrated in
Figures 4A and 4B , theshunt tubes 30a-b run adjacent each wellscreen basepipe joint 14a-b of the assemblies, and thejumper tube 200 fits between end rings 20a-b. In one example, the ends of theshunt tubes 35 may fit at least partially in or beyondslots 22 in each of the end rings 20a-b. In another example however, thejumper tube 200 can engage directly to a portion of the end rings 20a-b, wherein the end rings 20a-b have openings and/or slots for thejumper tube 200. The end rings 20a-b may also have connector ends that have lock components disposed thereon for locking with thejumper tube connectors 210a-b when theconnectors 210a-b have been extended. -
Figures 5A-5B illustrate side and partial cross-sectional views of thejumper tube 200 being installed on opposingshunt tubes 30a-b. As shown at the disengaged connection (left side), thejumper tube connector 210a is in a retracted position, which allows theend 205a of thejumper tube 200 to be set up and aligned with theshunt tube end 35. As shown at the engaged connection (right side), the otherjumper tube connector 210b is engaged with theshunt tube end 35. As described above, thejumper tube connector 210b can engage theshunt tube end 35 by moving into the extended position over theshunt tube end 35, and by engaging the locking features of theconnector 210b with the locking features of theshunt tube end 35. - As best shown in
Figures 6A-6B , the inside of theconnectors 210a-b are shown having locking features in the form ofthread 217 disposed in the interior. Also, the ends 35 of theshunt tube 30 have locking features in the form ofthread 37 disposed around the exterior. As described above, thethreads connectors 210a-b to progress over them with a sliding action and to then lock theconnectors 210a-b to the ends 35. In general, theconnectors 210a-b can extend over theends 35 at any suitable length and achieve the desired locking. - After the
connectors 210a-b have been engaged with the shunt tube ends 35, theconnectors 210a-b may be disengaged from theend 35 depending on the type of locking feature (e.g., thread or ratchet thread) used. For example, by rotating theconnectors 210a-b in either a clockwise or counterclockwise direction, thethreads 217 of theconnectors 210a-b may be able to unlock with thethreads 37 of the shunt tube ends 35. In other words, by rotating theconnector 210a-b, the connectors'threads 217 can effectively unthread from the tubes'threads 217 so that theconnectors 210a-b becomes disconnected from the ends 35. Allowing theconnectors 210a-b to disengage theends 35 can allow thejumper tube 200 to be easily disconnected from thewell screen assembly 10, if necessary. - Closer details of the ratchet thread configuration on the
connectors 210a-b and theends 35 are shown inFigure 6C . As shown in the partial cross sectional view inFigure 6C , one of thejumper tube connectors 210b is disposed in an extended position on thejumper tube end 205b and has engaged with theshunt tube end 35. In this illustration, theconnector 210b and theend 35 each haveratchet thread - As the
connector 210b moves or slides over theend 35, theratchet thread 217 on the inner surface of theconnector 210b slides past theratchet thread 37 disposed on the exterior surface of theshunt tube end 35. As illustrated, theratchet thread 217 disposed inside theconnector 210b then locks with theratchet thread 37 on theend 35 by biasing the ratchet threading of thesethreads ratchet threads connector 210b is locked into its extended condition, and theconnector 210b is not able to slide in the opposite direction away from theend 35. - Additionally, the
jumper tube end 205b may also have aratchet thread 207 disposed thereon. In particular, theratchet thread 207 may assist theconnector 210b during engagement by being biased in an opposite direction relative to the connector'sratchet thread 217 in a manner similar to the shunt tube'sthread 37. As described above, this will allow theconnector 210b to slide along theend 205b in one direction without locking, while being locked and or unable to slide back in the opposite direction, thereby making the engagement more secure. - As shown in
Figure 6C , the entire inner surface of theconnector 210b may have theratchet thread 217. Likewise, the expanse ofratchet thread shunt tube end 35 and thejumper end 205b can encompass a comparable expanse. As an alternative, all or a portion of the inner surface of theconnector 210b may lack a threaded portion, and all or a portion of thejumper tube end 205b may also lack a threaded portion. Instead, a portion of the outer surface of thejumper tube end 205b may engage portion of the connector's inner surface with an interference fit. - As described previously, the
connectors 210a-b in some arrangements may allow for disengagement from theend 35 by being retracted away from shunt tube ends 35. To do this, theconnector 210a-b may be rotated, which may allow theconnectors 210a-b to rotate off theratchet threads 37 of the shunt tube ends 35 and may thereby allow thejumper tube 200 to be removed. - For example, one or more of the
ratchet threads connector 210a-b is rotated, theconnector 210a-b can be separated from theend 35 by unthreading the thread in an unscrewing fashion. However, considering that the connection is preferably a fixed connection, theratchet thread ratchet thread thread connectors 210a-b and/or on theends - As a result of the engagement described above, the ratchet threading effectively allows the
connector 210a-b to move or slide over theends 205a-b and 35 in one direction, but lock and prevent theconnector 210a-b from sliding or moving in the opposite direction. - As noted above, both ends 205a-b of the
jumper tube 200 preferably have slidingconnectors 210a-b, but in other embodiments, only one slidingconnector 210 may be used. As shown inFigure 8 , for example, ajumper tube 200 is shown fitting between opposingshunt tubes 30a-b. Oneend 205b of thejumper tube 200 can have a fitting 208 or the like that directly couples with anend 35 of theshunt tube 30b. For example, the fitting 208 can use an interference fit, can lock with a ratchet thread, can thread with spiral thread, or can connect in a conventional manner (i.e., pin, bolt, etc.). In this example, theend 35 hasratchet thread 37 against which the fitting 208 engages. - Either way, the
opposite end 205a of thejumper tube 200 can have the slidingend connector 210a for first aligning with theshunt tube end 35 and then sliding onto theend 35, as discussed herein. Because room may be necessary to position thejumper tube 200 between the opposed ends 35, thejumper tube 200 may be shorter a distance D between the opposed ends 35, and portion of theconnector 210a may be used to complete the connection between theend 35 and thejumper tube 200 when the connection is made. - The foregoing description of preferred and other embodiments is not intended to limit or restrict the scope or applicability of the inventive concepts conceived of by the Applicants. It will be appreciated with the benefit of the present disclosure that features described above in accordance with any embodiment or aspect of the disclosed subject matter can be utilized, either alone or in combination, with any other described feature, in any other embodiment or aspect of the disclosed subject matter.
- In exchange for disclosing the inventive concepts contained herein, the Applicants desire all patent rights afforded by the appended claims. Therefore, it is intended that the appended claims include all modifications and alterations to the full extent that they come within the scope of the following claims or the equivalents thereof.
