The present disclosure relates generally to zonal isolation devices that include sensing and wireless telemetry, as well as to methods of utilizing the zonal isolation devices.
Hydrocarbon wells often utilize one or more zonal isolation devices. These zonal isolation devices, which may include bridge plugs and/or swellable packers, may be utilized to restrict fluid flow within a fluid conduit of the hydrocarbon well. As an example, in a well that includes distinct oil-producing and water-producing intervals, a swellable packer may be utilized to restrict production of water from the water-producing intervals. As another example, bridge plugs may be utilized to temporarily, or even permanently, isolate a section, or region, of the fluid conduit. The fluid conduit may be defined solely by a wellbore of the hydrocarbon well, may be defined solely by a downhole tubular that extends within the wellbore, and/or may be defined within an annular space that extends between the wellbore and the downhole tubular. Thus, zonal isolation devices may be in contact with, or may be configured to seal against, the wellbore and/or the downhole tubular.
In certain circumstances, it may be desirable to monitor and/or quantify a quality of isolation that is provided by a given zonal isolation device, to monitor one or more properties of the well in a region that is proximal to the zonal isolation device, and/or to selectively permit fluid flow past the zonal isolation device. Each of these activities generally requires wireline and/or coiled tubing workovers, and such workovers are costly and time-intensive. Thus, there exists a need for improved zonal isolation devices including sensing and wireless telemetry, as well as for methods of utilizing the zonal isolation devices.
Zonal isolation devices including sensing and wireless telemetry and methods of utilizing the same are disclosed herein. The zonal isolation devices include an isolation body, a sensor, and a wireless telemetry device. The isolation body is configured to transition from a contracted conformation to an expanded conformation. In the contracted conformation, a characteristic dimension of the isolation body is less than a characteristic dimension of a fluid conduit of the well such that the zonal isolation device is free to move within the fluid conduit. In the expanded conformation, the characteristic dimension of the isolation body is increased such that the isolation body, and thus the zonal isolation device, is positionally fixed within the fluid conduit and restricts fluid flow of a wellbore fluid within the fluid conduit. The sensor is configured to detect at least one property of the well. The wireless telemetry device is operatively attached to both the isolation body and to the sensor when the isolation body is in both the contracted conformation and the expanded conformation. The wireless telemetry device is configured to transmit a wireless output signal to a wireless data transmission network, and the wireless output signal is indicative of the at least one property of the well.
The zonal isolation devices may be incorporated into a hydrocarbon well that also includes a wellbore and the wireless data transmission network. The wellbore extends between a surface region and a subterranean formation. The wireless data transmission network includes a plurality of relay nodes spaced-apart along a length of the wellbore.
The methods include methods of conveying a wireless signal within a well that includes a wellbore that extends within a subterranean formation. The methods include detecting a property of the well with a sensor of a zonal isolation device. The methods also include transmitting a wireless output signal, which is indicative of the property of the well, with a wireless telemetry device of the zonal isolation device. The methods further include conveying the wireless output signal along a length of the wellbore. The methods also include receiving the wireless output signal with a relay node receiver of a relay node that is positioned within the fluid conduit and spaced-apart from the zonal isolation device along the length of the wellbore.
Hydrocarbon wells 20 also include a wireless data transmission network 50 including a plurality of relay nodes 60 spaced-apart along a length of wellbore 30. Hydrocarbon wells 20 further include zonal isolation device 100. As discussed in more detail herein with reference to
During operation of hydrocarbon well 20, and as discussed in more detail herein with reference to methods 200 of
Stated another way, hydrocarbon wells 20 according to the present disclosure, which include wireless data transmission networks 50 and zonal isolation devices 100, may be configured such that data, such as the at least one property of the hydrocarbon well, that is sensed and/or detected by sensor 160 of zonal isolation device 100 may be wirelessly conveyed along the length of the wellbore in any suitable direction as wireless output signals 134. Such a configuration may permit sensing of the at least one property of the hydrocarbon well in a region of the wellbore that is proximal to zonal isolation device 100 without the need to perform costly wireline and/or coiled tubing workovers. Such a configuration additionally or alternatively may permit the at least one property of the hydrocarbon well to be conveyed along the length of the wellbore without utilizing physical and/or wired connections, thereby avoiding fluid leakage pathways that may be present along the length of the physical and/or wired connections.
Wireless data transmission network 50 may include any suitable structure that includes relay nodes 60 and/or that is configured to wirelessly transmit wireless output signal 134 along at least a portion of the length of wellbore 30. This transmission may be accomplished in any suitable manner. As an example, relay nodes 60 may be configured to wirelessly propagate, or relay, the wireless output signal along the length of the wellbore, such as from the zonal isolation device to surface region 10. As a more specific example, a given relay node may receive the wireless output signal and then may transmit the wireless output signal to an adjacent relay node. This process may be repeated any suitable number of times utilizing any suitable number of relay nodes 60 to wirelessly convey the wireless output signal along any suitable portion of the length of the wellbore.
Relay nodes 60 may include any suitable structure. As examples, each relay node 60 may include a relay node transmitter 62, which is configured to produce, generate, and/or transmit wireless output signal 134, and a relay node receiver 64, which is configured to receive the wireless output signal.
It is within the scope of the present disclosure that relay nodes 60 may wirelessly propagate, or convey, wireless output signal 134 via any suitable mechanism and/or utilizing any suitable conveyance medium. Examples of the wireless output signal include one or more of an electromagnetic signal, a fluid pressure pulse within a wellbore fluid that extends within the wellbore, a radio frequency signal, a low frequency radio signal, a mechanical wave, a vibration, and/or an acoustic signal. Examples of the conveyance medium are discussed herein.
It is within the scope of the present disclosure that wellbore 30 may include and/or be any suitable wellbore that extends within subterranean formation 14. As an example, and as illustrated in solid lines in
As illustrated in dashed lines in
Additionally or alternatively, it is within the scope of the present disclosure that hydrocarbon well 20 may be an open-hole completion hydrocarbon well that does not include downhole tubular 40 and/or that downhole tubular 40 may not extend along an entirety of a length of the wellbore. Under these conditions, wellbore 30 may be referred to herein as the defining, or as solely defining, fluid conduit 32, and the fluid conduit also may be referred to herein as a wellbore conduit 32.
Zonal isolation devices 100 also may be referred to herein as zonal control devices and may include any suitable structure that includes wireless telemetry device 130 and sensor 160. More specific and/or detailed examples of zonal isolation devices 100 are illustrated in
As illustrated in
When zonal isolation device 100 is utilized within hydrocarbon wells 20, the zonal isolation device initially may be introduced into and/or positioned within fluid conduit 32 while in contracted conformation 122 and may be moved, flowed, and/or conveyed to a desired, or target, location within the fluid conduit. Subsequently, the zonal isolation device may be transitioned to expanded conformation 124 such that the zonal isolation device is retained within the desired, or target, location within the fluid conduit. When in expanded conformation 124, the zonal isolation device may restrict, limit, or even block flow of wellbore fluid 34 therepast and within fluid conduit 32. This may include stopping fluid flow such that no wellbore fluid flows past the zonal isolation device. As another example, this may include restricting, but not necessarily stopping, flow of the wellbore fluid past the zonal isolation device.
When zonal isolation device 100 is positioned within fluid conduit 32, and whether the zonal isolation device is in contracted conformation 122 or expanded conformation 124, sensor 160 may be utilized to sense and/or detect at least one property of well 20, as discussed in more detail herein. In addition, wireless telemetry device 130 may transmit a wireless output signal 134 to a wireless data transmission network 50 that extends within a wellbore 30 of the hydrocarbon well, as illustrated in
It is within the scope of the present disclosure that zonal isolation device 100 may include and/or be any suitable zonal isolation device that may be adapted, configured, designed, and/or constructed to restrict fluid flow within any suitable fluid conduit 32 that may be present and/or defined within hydrocarbon well 20. As an example, and as illustrated in
As another example, and as illustrated in
As yet another example, and as illustrated in
In the above examples, wellbore 30 may be defined within any suitable structure. As an example, wellbore 30 may be defined within a subterranean formation 14. As another example, wellbore 30 may be defined within cement 38, which may be positioned within the subterranean formation. When fluid conduit 32 is defined, or fully defined, by wellbore 30, subterranean formation 14 and/or cement 38 may be referred to herein as the tubular body that defines the fluid conduit.
Returning to
It is within the scope of the present disclosure that sensors 160 may measure and/or detect any suitable property, or properties, of the well. Examples of the property, or properties of the well include a pressure drop across the zonal isolation device, a fluid conductivity between two spaced-apart regions of the subterranean formation, sand motion proximal the zonal isolation device, an acoustic property of the downhole tubular, when present, and/or an acoustic property of the subterranean formation.
Such detected properties may be utilized to determine and/or quantify whether or not fluid containment provided by the zonal isolation device is functioning, or functioning as expected, and/or to determine and/or quantify failure of the zonal isolation device. As examples, detection of the pressure drop across the zonal isolation device, detection of the fluid conductivity between two spaced-apart regions of the subterranean formation, and/or detection of sand motion proximal the zonal isolation device may be utilized to estimate and/or quantify a property that is indicative of a seal integrity of the zonal isolation device, such as by indicating whether or not fluid is flowing past the zonal isolation device within the fluid conduit.
Additionally or alternatively, such detected properties may be utilized by an operator of the hydrocarbon well to determine whether or not it is safe to drill out, or remove, the zonal isolation device and/or to verify that an abandoned well is effectively sealed, such as by the zonal isolation device. As an example, detection of the pressure drop across the zonal isolation device may be utilized to determine whether or not the pressure drop is less than a threshold pressure drop below which it is safe to drill out, or remove, the zonal isolation device.
Additionally or alternatively, such detected properties may be utilized to determine and/or quantify an integrity of wellbore 30 and/or of downhole tubular 40, when present. As an example, the acoustic property of the downhole tubular, or changes in the acoustic property of the downhole tubular as a function of time, may indicate thinning, corrosion, and/or occlusion of the downhole tubular. As another example, the acoustic property of the subterranean formation, or changes in the acoustic property of the subterranean formation as a function of time, may indicate changes in a fluid conductivity of the subterranean formation and/or cracking of the subterranean formation.
It is within the scope of the present disclosure that sensors 160 may be adapted, configured, designed, and/or constructed to determine, detect, and/or quantify any suitable one or more other properties of the well. Examples of the properties of the well include a temperature, a pressure, a vibrational amplitude, a vibrational frequency, a strain within the zonal isolation device, an electrical conductivity of the wellbore fluid, a flow rate of the wellbore fluid, a presence of a multiphase flow within the fluid conduit, a chemical composition of the wellbore fluid, a density of the wellbore fluid, and/or a viscosity of the wellbore fluid.
Similarly, sensors 160 may include any suitable structure that is adapted, configured, designed, and/or constructed to determine, detect, and/or quantify the at least one property of the well. As examples, sensors 160 may include one or more of a temperature sensor, a pressure sensor, a differential pressure sensor, a differential pressure sensor configured to detect a pressure differential between an uphole side of the zonal isolation device and a downhole side of the zonal isolation device, an acoustic sensor, a vibration sensor, an acoustic transmitter, an acoustic receiver, a strain gauge, an electrical conductivity sensor, a fluid flow meter, a multiphase flow sensor, a chemical composition sensor, a fluid density sensor, and/or a viscosity sensor.
When sensors 160 include the vibration sensor and/or detect the vibrational amplitude and/or frequency, the sensors may detect any suitable vibration. As examples, the sensors may detect passive, or passively initiated, vibrations, such as vibrations that result from fractures within the subterranean formation, deformation of seals, and/or actuation of valves. Additionally or alternatively, the sensors may detect active vibrations, such as low frequency and/or ultrasound vibrations, or pings, which may be selectively initiated by a vibration source, and/or related vibrations due to reflection and/or scattering of the pings.
Wireless telemetry device 130 may include any suitable structure that may be adapted, configured, designed, constructed, and/or programmed to transmit the wireless output signal to the wireless data transmission network and/or to communicate with one or more relay nodes of the wireless data transmission network. As an example, and as illustrated in
Examples of the wireless transmitter include an electromagnetic transmitter, an acoustic transmitter, and/or a radio frequency transmitter. An example of an acoustic transmitter includes a piezoelectric transmitter element 141, which may be configured to vibrate at a data transmission frequency to produce and/or generate the wireless output signal in the form of an acoustic wireless output signal. When wireless transmitter 140 includes, or is, the acoustic transmitter, the acoustic transmitter further may include a rigid plate 142, which may be operatively linked to the piezoelectric transmitter element and/or may be configured to vibrate with the piezoelectric transmitter element. Examples of rigid plate 142 include a metallic plate, a steel plate, and/or an aluminum plate.
When wireless transmitter 140 includes piezoelectric transmitter element 141 and rigid plate 142, the rigid plate may be in contact, or in direct physical contact, with the piezoelectric transmitter element. Additionally or alternatively, the rigid plate may extend between the piezoelectric transmitter element and wellbore fluid 34 when, or while, the zonal isolation device is positioned within fluid conduit 32.
It is within the scope of the present disclosure that, when zonal isolation device 100 is positioned within the tubular conduit and in expanded conformation 124, rigid plate 142 may be in contact, or in direct physical contact, with a tubular body that defines fluid conduit 32. This is illustrated in dash-dot lines in
Gap 90, when present, may not extend between an entirety of zonal isolation device 100 and an entirety of the tubular body. Instead, and as illustrated, gap 90 extends between a portion, fraction, or region of the zonal isolation device and a portion, fraction, or region of the tubular body. As an example, gap 90 may be an annular gap 90 that is defined between the zonal isolation device and the tubular body. As another example, gap 90 may be defined between an outer surface of the zonal isolation device and an inner surface and/or an outer surface of the tubular body.
Wireless output signal 134 may include, or be, any suitable signal. As examples, the wireless output signal may include one or more of an electromagnetic signal, a fluid pressure pulse within the wellbore fluid, a radio frequency signal, a mechanical wave, a vibration, and/or an acoustic signal.
Furthermore, the wireless telemetry device may be configured to transmit the wireless output signal via, through, and/or utilizing any suitable conveyance, or transmission, medium. In addition, a nature, amplitude, and/or frequency of the wireless output signal may be selected and/or tuned for a specific conveyance medium. As an example, and as illustrated in
It is within the scope of the present disclosure that sensor 160 may measure the at least one property of the well and/or that wireless telemetry device 130 may be programmed to transmit the wireless output signal based upon, or responsive to, any suitable criteria. As examples, the wireless telemetry device may be programmed to transmit, or to initiate transmission of, the wireless output signal responsive to measurement of the at least one property of the well by the sensor, periodically, and/or based upon a predetermined elapsed time interval. As another example, the wireless telemetry device may be programmed to transmit the wireless output signal responsive to receipt of a wireless input signal 132, such as a wireless data query 170, which may be transmitted to the zonal isolation device and/or to wireless receiver 150 thereof from wireless data transmission network 50 and/or a relay node 60 thereof, as illustrated in
As yet another example, the wireless telemetry device may be programmed to transmit the wireless output signal responsive to satisfaction of a predetermined data transmission condition. Examples of the predetermined data transmission condition include detection, by the sensor, of less than a lower threshold pressure drop across the zonal isolation device, detection, by the sensor, of greater than an upper threshold pressure drop across the zonal isolation device, detection, by the sensor, of greater than a threshold fluid flow rate past the zonal isolation device, and/or detection, by the sensor, of failure of a seal between the isolation body and a downhole tubular that at least partially defines the fluid conduit.
Wireless receiver 150 may include any suitable structure. As examples, wireless receiver 150 may include, or be, an electromagnetic receiver, an acoustic receiver, a piezoelectric receiver element, and/or a radio frequency receiver.
It is within the scope of the present disclosure that wireless telemetry device 130 additionally or alternatively may be configured to receive wireless input signal 132 and to generate wireless output signal 134 based, at least in part, on the wireless input signal and/or upon receipt of the wireless input signal. As an example, wireless input signal 132 and wireless output signal 134 both may be representative, or indicative, of a propagated data stream that is propagated along a length of fluid conduit 32 by, via, and/or utilizing zonal isolation device 100, as discussed in more detail herein.
Isolation body 120 may include any suitable structure that may be adapted, configured, designed, and/or constructed to transition between contracted conformation 122 and expanded conformation 124. As an example, isolation body 120 may include, or be, an elastomeric body configured to be deformed to transition from the contracted conformation to the expanded conformation. As another example, isolation body 120 may include, or be, a swellable material selected and/or configured to swell, upon contact with the wellbore fluid, to transition from the contracted conformation to the expanded conformation.
It is within the scope of the present disclosure that isolation body 120 may expand in any suitable manner, or direction, upon transitioning from the contracted conformation to the expanded conformation. As an example, and as illustrated in dash-dot lines in
As illustrated in dashed lines in
As a more specific example, wirelessly triggered actuator 180 may include, or be, a wirelessly actuated valve 182 configured to control and/or regulate fluid flow through a pass-through conduit 186. Wirelessly actuated valve 182 may define an open configuration, in which the wirelessly actuated valve permits fluid flow through pass-through conduit 186, and a closed configuration, in which the wirelessly actuated valve restricts fluid flow through the pass-through conduit. The actuated configuration may correspond to the open configuration and the unactuated configuration may correspond to the closed configuration. Under these conditions, wirelessly actuated valve 182 may be configured to selectively transition from the closed configuration to the open configuration, such as to permit wellbore fluid 34 to flow past zonal isolation device 100, responsive to receipt of wireless actuation signal 184. Such a configuration may permit selective pressure equalization across the zonal isolation device while the zonal isolation device is positioned within fluid conduit 32 and in expanded conformation 124.
Detecting the property of the well at 210 may include detecting any suitable property of the well with and/or utilizing a sensor of a zonal isolation device. This may include detecting the property of the well with and/or utilizing sensor 160 of
Transmitting the wireless output signal at 220 may include transmitting the wireless output signal with a wireless telemetry device of the zonal isolation device. The wireless output signal may be indicative of the property of the well that was detected during the detecting at 210, and the zonal isolation device may be positioned, or even positionally fixed, within a fluid conduit that extends within the wellbore. The transmitting at 220 may include transmitting with and/or utilizing any suitable wireless telemetry device, examples of which are disclosed herein with respect to wireless telemetry device 130 of

While not required of all embodiments, it is within the scope of the present disclosure that the conveying at 230 may include conveying an entirety of the wireless output signal via a non-metallic conveyance medium over at least a portion of a transmission distance between the zonal isolation device and a relay node. As an example, and as discussed herein with reference to
As another example, and as discussed herein with reference to
As yet another example, the zonal isolation device, or the isolation body thereof, may be in direct physical contact with the wellbore, such as with a subterranean formation and/or with cement that defines the wellbore. Under these conditions, the conveying at 230 may include conveying an entirety of the wireless output signal from the wireless telemetry device and over at least a portion of a distance to the relay node via the wellbore fluid, via the subterranean formation, and/or via the cement.
The conveying at 230 may include conveying any suitable wireless output signal. Examples of the wireless output signal are disclosed herein.
Receiving the wireless output signal at 240 may include receiving the wireless output signal with the relay node, such as relay nodes 60 of
Propagating the wireless output signal at 250 may include propagating, relaying, and/or repeating the wireless output signal along the length of the fluid conduit. As an example, the relay node may be a first relay node in a wireless data transmission network that includes a plurality of spaced-apart relay nodes. Under these conditions, the propagating at 250 may include propagating the wireless output signal from the zonal isolation device, along the length of the fluid conduit, and/or to a surface region via and/or utilizing at least a portion of the plurality of spaced-apart relay nodes. This may include transmitting the wireless output signal from the first relay node, receiving the wireless output signal with a second relay node, transmitting the wireless output signal from the second relay node, and/or receiving the wireless output signal with a third relay node. This process may be repeated any suitable number of times utilizing any suitable number of relay nodes.
It is within the scope of the present disclosure that zonal isolation devices 100, hydrocarbon wells 20, and/or methods 200 disclosed herein may be modified in any suitable manner. Additionally or alternatively, it is also within the scope of the present disclosure that one or more structures, components, and/or features of zonal isolation devices 100 and/or methods 200 disclosed herein may be utilized with one or more other structures, components, and/or features of a hydrocarbon well, such as hydrocarbon well 20 of
As an example, the zonal isolation device instead may be another, or a different, downhole structure that may be configured for wireless communication within a fluid conduit. Under these conditions, the other downhole structure may include wireless telemetry device 130 and sensor 160 but is not necessarily required to include isolation body 120 and may be positionally fixed within the fluid conduit in any suitable manner. As an example, the other downhole structure may include a spike, which may be driven into the tubular body that defines the fluid conduit. Such a downhole structure may be referred to herein as a data node and/or as a downhole data node.
As another example, the other downhole structure may include, or be, a zonal control device configured to regulate, but not necessarily to block, fluid flow within the hydrocarbon well. An example of such a zonal control device is an inflow restriction. Such a zonal control device still may include wireless telemetry device 130 and sensor 160 and may be positionally fixed within the fluid conduit via a threaded connection, via a fastener, and/or via a weld. As an example, such a zonal control device may be installed within a downhole tubular, such as a casting string or production tubing, prior to the downhole tubular being positioned within the wellbore.
In the present disclosure, several of the illustrative, non-exclusive examples have been discussed and/or presented in the context of flow diagrams, or flow charts, in which the methods are shown and described as a series of blocks, or steps. Unless specifically set forth in the accompanying description, it is within the scope of the present disclosure that the order of the blocks may vary from the illustrated order in the flow diagram, including with two or more of the blocks (or steps) occurring in a different order and/or concurrently. It is also within the scope of the present disclosure that the blocks, or steps, may be implemented as logic, which also may be described as implementing the blocks, or steps, as logics. In some applications, the blocks, or steps, may represent expressions and/or actions to be performed by functionally equivalent circuits or other logic devices. The illustrated blocks may, but are not required to, represent executable instructions that cause a computer, processor, and/or other logic device to respond, to perform an action, to change states, to generate an output or display, and/or to make decisions.
As used herein, the term “and/or” placed between a first entity and a second entity means one of (1) the first entity, (2) the second entity, and (3) the first entity and the second entity. Multiple entities listed with “and/or” should be construed in the same manner, i.e., “one or more” of the entities so conjoined. Other entities may optionally be present other than the entities specifically identified by the “and/or” clause, whether related or unrelated to those entities specifically identified. Thus, as a non-limiting example, a reference to “A and/or B,” when used in conjunction with open-ended language such as “comprising” may refer, in one embodiment, to A only (optionally including entities other than B); in another embodiment, to B only (optionally including entities other than A); in yet another embodiment, to both A and B (optionally including other entities). These entities may refer to elements, actions, structures, steps, operations, values, and the like.
As used herein, the phrase “at least one,” in reference to a list of one or more entities should be understood to mean at least one entity selected from any one or more of the entity in the list of entities, but not necessarily including at least one of each and every entity specifically listed within the list of entities and not excluding any combinations of entities in the list of entities. This definition also allows that entities may optionally be present other than the entities specifically identified within the list of entities to which the phrase “at least one” refers, whether related or unrelated to those entities specifically identified. Thus, as a non-limiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and/or B”) may refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including entities other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including entities other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other entities). In other words, the phrases “at least one,” “one or more,” and “and/or” are open-ended expressions that are both conjunctive and disjunctive in operation. For example, each of the expressions “at least one of A, B and C,” “at least one of A, B, or C,” “one or more of A, B, and C,” “one or more of A, B, or C” and “A, B, and/or C” may mean A alone, B alone, C alone, A and B together, A and C together, B and C together, A, B and C together, and optionally any of the above in combination with at least one other entity.
In the event that any patents, patent applications, or other references are incorporated by reference herein and (1) define a term in a manner that is inconsistent with and/or (2) are otherwise inconsistent with, either the non-incorporated portion of the present disclosure or any of the other incorporated references, the non-incorporated portion of the present disclosure shall control, and the term or incorporated disclosure therein shall only control with respect to the reference in which the term is defined and/or the incorporated disclosure was present originally.
As used herein the terms “adapted” and “configured” mean that the element, component, or other subject matter is designed and/or intended to perform a given function. Thus, the use of the terms “adapted” and “configured” should not be construed to mean that a given element, component, or other subject matter is simply “capable of” performing a given function but that the element, component, and/or other subject matter is specifically selected, created, implemented, utilized, programmed, and/or designed for the purpose of performing the function. It is also within the scope of the present disclosure that elements, components, and/or other recited subject matter that is recited as being adapted to perform a particular function may additionally or alternatively be described as being configured to perform that function, and vice versa.
As used herein, the phrase, “for example,” the phrase, “as an example,” and/or simply the term “example,” when used with reference to one or more components, features, details, structures, embodiments, and/or methods according to the present disclosure, are intended to convey that the described component, feature, detail, structure, embodiment, and/or method is an illustrative, non-exclusive example of components, features, details, structures, embodiments, and/or methods according to the present disclosure. Thus, the described component, feature, detail, structure, embodiment, and/or method is not intended to be limiting, required, or exclusive/exhaustive; and other components, features, details, structures, embodiments, and/or methods, including structurally and/or functionally similar and/or equivalent components, features, details, structures, embodiments, and/or methods, are also within the scope of the present disclosure.
The systems and methods disclosed herein are applicable to the oil, gas, and well drilling industries.
