CONTEXT

[0002] Downhole devices, such as subsurface safety valves (SSSVs), are well known in the oil and gas industry and are one of several built-in safety mechanisms to prevent the uncommanded release of subsurface production fluids, if a wellbore system experiences a loss of containment. In some cases, SSSVs comprise a portion of a production string, with the entire SSSV being deployed upon completion of a wellbore. In other cases, SSSVs are deployed / retrieved by wireline. While a number of design variations are possible for SSSVs, the vast majority are flapper valves that open and close in response to longitudinal movement of a flowtube.

[0003] Since SSSVs generally provide a fail-safe mechanism, the default position of the flapper valve is generally closed to minimize the risk of accidental release of subterranean production fluids. The gate valve can be opened by various control means from the earth's surface to provide a flow path for production. What is needed in the art is an improved SSSV that does not suffer from the problems of existing SSSVs. BRIEF DESCRIPTION

DETAILED DESCRIPTION

[0015] In the following drawings and descriptions, similar parts are generally indicated in the specification and drawings by means of the same reference numerals, respectively. The drawn figures are not necessarily to scale. Some elements of the disclosure may be shown on an exaggerated scale or in a rather schematic form, and some details of some elements may not be shown for the sake of clarity and brevity. The present disclosure may be embodied in embodiments of various forms. Specific embodiments are described in detail and illustrated in the drawings, it being understood that the present disclosure is to be considered an exemplification of the principles of the disclosure and is not intended to limit the disclosure to what is illustrated and described herein.It must be recognized that the various teachings of the embodiments discussed herein may be employed separately or in any suitable combination to produce the desired results.

[0016] Unless otherwise indicated, the use of the terms "connect," "engage," "couple," "attach," or any other similar term describing an interaction between elements is not intended to limit the interaction to a direct interaction between the elements and may also include an indirect interaction between the elements described.

However, the values / ranges of any lower limit may be combined with any upper limit to cite a range not explicitly cited. Similarly, the values / ranges of Any lower bound may be combined with any other lower bound to obtain a range that is not explicitly cited. Similarly, the values / ranges of any upper bound may be combined with any other upper bound to cite a range not explicitly cited. Moreover, whenever a numerical range with a lower bound and an upper bound is disclosed, any number and range within the range is specifically disclosed.

The term "ideally XYZ," as used herein, means within 1% of perfectly XYZ. The abbreviation "XYZ" may refer to parallel, perpendicular, alignment, or other related features disclosed herein.

[0019] The present disclosure recognizes that offshore wells are drilled in ever-increasing water depths and in environmentally vulnerable waters, and that safety valves (e.g., subsurface safety valves (SSSVs)) are therefore required. The present disclosure further recognizes that SSSVs have parts that may wear or erode and, from time to time, may therefore require maintenance and / or replacement. In fact, there are times when the tubing retrievable safety valve (TRSV) (e.g., an electrically actuated TRSV) fails and a wireline retrievable safety valve (WLRSV) is installed down the hole. Unfortunately, the TRSV and WLRSV each require their own power source, such as individual tubing encapsulated conductors (TECs).

[0020] The present disclosure has enabled the development of an improved WLRSV. In at least one embodiment, the WLRSV comprises a first portion which is introduced into the hole with the TRSV and second and third portions which are introduced into the hole after the TRSV no longer functions properly and / or has failed. The first portion of the WLRSV, in at least one embodiment, includes a safety valve subassembly (e.g., the WLRSV subassembly) that would be introduced into the hole along with another safety valve subassembly (e.g., the TRSV subassembly) and, for example, the production string. In at least one embodiment, the safety valve subassembly is located above the TRSV subassembly. In at least one other embodiment, the safety valve subassembly would include an electromagnetic assembly (e.g., including one or more coils) (e.g., coupleable to the primary control line (e.g., a single TEC) via the aforementioned switching system) positioned within a pocket in the WLRSV subassembly, as well as a fluid isolation sleeve that isolates the electromagnetic assembly and the pocket from fluid and / or debris within the wellbore.In at least one embodiment, the fluid isolation sleeve is a fixed fluid isolation sleeve and therefore does not readily move once positioned downhole.

[0021] In one or more embodiments, the WLRSV further comprises the second portion of the WLRSV, which is inserted into the bore after the TRSV is no longer functioning properly and / or has failed. The second portion of the WLRSV, according to one or more embodiments, may be inserted into the bore within the TRSV, for example using a locking mechanism to axially secure the second portion of the WLRSV within the TRSV. The second portion of the WLRSV, in one or more embodiments, may comprise a bore flow management actuator and a valve closing mechanism, and may be located below the first portion of the WLRSV comprising the electromagnetic assembly and the fluid isolation sleeve. The second portion may further comprise an axially secured magnetic target portion, axially and / or radially aligned with the electromagnetic assembly.The term "magnetic target," as used herein, may be a permanent magnet, a ferromagnetic material feature, or another feature that exhibits a magnetic field (e.g., a sufficiently large magnetic field) or a response to an applied magnetic field (e.g., a sufficiently large response to an applied magnetic field). In at least one embodiment, however, the axially attached magnetic target portion is a ferromagnetic material feature. The second portion of the WLRSV may also include a power spring and / or a nose spring, as will be explained in more detail below.

[0022] In one or more embodiments, the WLRSV further comprises a third portion which is introduced into the hole after the second portion of the WLRSV has been locked downhole (e.g., locked within the TRSV or the first portion of the WLRSV). In another embodiment, the third portion is introduced into the hole after the second portion has been introduced into the hole during a separate wellbore operation, such as a separate wireline run or a separate slickline run. In another embodiment, the third portion is introduced into the hole after the second portion during the same wellbore operation, such as during the same wireline run or slickline run. The third portion, in one or more embodiments, includes a mechanical connection apparatus.For example, according to one or more embodiments of the disclosure, once the second portion of the WLRSV is locked in place, the mechanical connection apparatus may be inserted into the bore and coupled to the flow tube of the second portion. In at least this embodiment, the mechanical connection apparatus is located radially within the electromagnetic assembly and / or the fluid isolation sleeve of the first portion. The mechanical connection apparatus, in one or more embodiments, has one or more magnetic targets associated therewith (e.g., coupled thereto or forming a portion thereof). In at least one embodiment, the one or more magnetic targets are axially and / or radially aligned with the axially attached magnetic target portion of the second portion and configured to slide axially relative to the axially attached magnetic target portion.The one or more magnetic targets, in this embodiment, are configured to magnetically couple to the axially attached magnetic target portion of the second part when the electromagnetic assembly of the first part is energized and the two are located in proximity to each other. Essentially, when the one or more magnetic targets and the axially attached magnetic target portion are positioned in proximity to each other, and the electromagnetic assembly is energized, a magnetic flux with a flux path emanating from (e.g., encircling) the electromagnetic assembly, one or more magnetic targets, and the axially attached magnetic target portion is formed.This magnetic flux and associated flux path maintain the one or more magnetic targets on the axially fixed magnetic target portion, and would thereby maintain the mechanical connection apparatus and bore flow management actuator of the second portion in the open position when the electromagnetic assembly is energized. The foregoing is discussed in the context of the second portion and the third portion being introduced into the bore at different times. Other embodiments may exist in which . the second part and the third part are introduced into the hole in one movement (i.e. they are already coupled to each other).

[0023] In operation, once the mechanical connection apparatus is in place, fluid pressure (e.g., within the tubular member below the valve closure mechanism) may push the bore flow management actuator toward the valve closure mechanism. Typically, the bore flow management actuator cannot move beyond the valve closure mechanism until the pressure differential across the valve closure mechanism is reduced / eliminated. Once the pressure differential across the valve closure mechanism is reduced / eliminated, e.g., by pumping fluid into the wellbore toward a high-hole side of the valve closure mechanism, the bore flow management actuator may be pushed past the valve closure mechanism, e.g., using one or more springs (e.g., power springs and / or nose springs).While the one or more magnetic targets are axially attached to the bore flow management actuator, axial movement of the bore flow management actuator also axially moves the one or more magnetic targets. This axial movement of the flow tube brings the one or more magnetic targets associated with the mechanical connection apparatus into proximity to (e.g., axially aligned with) the axially attached magnetic target portion. Accordingly, when the electromagnetic assembly of the first portion is energized (e.g., before, during, or after the one or more magnetic targets approach the axially attached magnetic target portion) and is located in proximity to the one or more magnetic targets, the one or more magnetic targets, and thus the bore flow management actuator axially attached thereto, can be maintained in the flow state.The one or more magnetic targets, the mechanical connection apparatus, and the associated bore flow management actuator will be maintained in this flow state until the electromagnetic assembly is no longer energized, such as when the power to the electromagnetic assembly is turned off or switched off. When this occurs, the one or more springs (e.g., power springs and / or nose springs) are allowed to return the bore flow management actuator, and the associated poppet valve, to the closed state.

[0024] The present disclosure has, for the first time, developed a switching system (e.g., mechanical, electrical, etc.) that will allow a single primary control line (e.g., a single TEC) to operate two different downhole tools, such as the TRSV (e.g., an electrically actuated TRSV) and / or the WLRSV (e.g., a WLRSV that can be maintained electrically in an open position), or to actuate redundant downhole tools, such as a wet fitting or actuator. For example, the switching system could transfer power between two different electrical devices (e.g., electromagnetic coils, an electric motor or pump, a piezoelectric actuator, a solenoid valve, etc.) of the two different downhole tools. As a further example, the switching system could transfer power from an electrical device that has failed to a redundant device that has not been powered. Thus, in at least one embodiment, the single primary control line (e.g., a single TEC) could be introduced downhole from the surface to the switching system, and then the switching system would switch power between the TRSV and the WLRSV, as needed.In at least one embodiment, the switching system would switch power from the TRSV to the WLRSV when the WLRSV is ready to be introduced into the hole, when the WLRSV is introduced into the hole, or after the WLRSV has been introduced into the hole.

[0025] Accordingly, a switching system designed, manufactured and / or operated according to one or more embodiments of the disclosure reduces the need to introduce additional control lines, for example in emergency operations, such as when the TRSV fails and a WLRSV is required. This reduces the complexity of completing completions, protecting control lines, penetrating tubing hangers and reducing overall cost to the customer.

[0026] [Fig. 1A] illustrates a well system 100 designed, manufactured, and / or operated according to one or more embodiments of the disclosure. The well system 100, in at least one embodiment, includes an offshore platform 110 connected to a first downhole device 170 (e.g., a first SSSV, such as a TRSV) inserted within a wellbore 130 (e.g., the wellbore extending through one or more subterranean formations) and to a second downhole device 180 (e.g., a second SSSV, such as a WLRSV) inserted within the wellbore 130 via a primary control line 120 (e.g., a primary electrical control line, a single electrical control line, a TEC, etc.). In at least one embodiment, the second downhole device 180 is an electrical connection for a WLRSV.For example, the electrical connection may be an inductive coupling, a capacitive coupling, or a conductive coupling with direct electrical contact, among others. An annular space 150 may be defined between the walls of the wellbore 130 (e.g., extending through a subterranean formation) and a conduit 140. A wellhead 160 may provide a means for transferring and sealing the conduit 140 against the wellbore 130 and provide a profile for hanging a subsea blowout preventer thereon. The . conduit 140 may be coupled to the wellhead 160. The conduit 140 may be any conduit such as casing, liner, production tubing, or other oil tubulars disposed in a wellbore. The first downhole device 170, or at least a portion thereof, may be interconnected with the conduit 140 (e.g., disposed inline with the conduit 140) and positioned in the wellbore 130. The second downhole device 180, or at least a portion thereof, may be interconnected with the conduit 140 (e.g., positioned within an ID or OD of the conduit 140) and positioned in the wellbore 130.In the illustrated embodiment, the second downhole device 180 is illustrated uphole of the first downhole device 170 (e.g., a portion thereof is introduced into the hole with the first downhole device 170 and another portion is introduced into the hole after the failure of the first downhole device 170), but there may be other embodiments in which the second downhole device 180 is located downhole of the first downhole device 170.

[0027] The primary control line 120 may extend into the wellbore 130 and be connected to the first downhole device 170 and the second downhole device 180. The primary control line 120 may provide actuating power to the first downhole device 170 and the second downhole device 180. As will be described in more detail below, power may be provided to the first downhole device 170 or the second downhole device 180 to actuate or deactivate the first downhole device 170 or the second downhole device 180.Actuation may include opening the first downhole device 170 or the second downhole device 180 to provide a flow path for subterranean production fluids to enter the conduit 140, and deactivation may include closing the first downhole device 170 or the second downhole device 180 to close a flow path for subterranean production fluids to enter the conduit 140. While the embodiment of [Fig.lA] illustrates only the first downhole device 170 and the second downhole device 180, there are other embodiments in which more than two downhole devices according to the disclosure are used.

[0028] In accordance with one embodiment of the disclosure, the well system 100 may further include a switching system 190a positioned between the primary control line 120 and each of the first downhole device 170 and the second downhole device 180. The switching system 190a, as discussed above, is configured to switch incoming power from the primary control line 120 between the first downhole device 170 and the second downhole device 180, depending on which of the first downhole device 170 or the second downhole device 180 the operator intends to operate (e.g., actuate). In at least one embodiment, the first downhole device 170 includes a first electrical device (e.g., electromagnetic coils, an electric motor or pump, a piezoelectric actuator, a solenoid valve, etc.) and the second downhole device 180 includes a second electrical device (e.g., electromagnetic coils, an electric motor or pump, a piezoelectric actuator, a solenoid valve, etc.), and the switching system 190a is configured to switch incoming power from the primary control line 120 between the first electrical device of the first downhole device 170 and the second electrical device of the second downhole device 180.

[0029] Although the embodiment of [Fig. 1A] uses a single primary control line 120 and the switching system 190a, other embodiments of the disclosure could use two or more different control lines with or without the switching system 190a. Although the well system 100 is shown in [Fig. 1A] as an offshore well system, one skilled in the art should be able to adopt the teachings herein to any type of well, including onshore or offshore. In the embodiment of [Fig. 1A], the first downhole device 170 is a TRSV, and the second downhole device 180 is a WLRSV.

[0030] Turning now to Figures 1B and 1C, an embodiment of a switching system 190b designed, manufactured and / or operated is illustrated in accordance with one or more embodiments of the disclosure, as it might be used in the well system 100 of [Fig. 1A]. The switching system 190b, in the illustrated embodiment, is a mechanical switching system. In the illustrated embodiment, the switching system 190b includes a mechanically activated switch 191, the mechanically activated switch 191 having an input thereof coupled to the primary control line 120, and a first output thereof coupled to the first downhole device 170 and a second output thereof coupled to the second downhole device 180. Accordingly, the mechanically activated switch 191 switches the input power of the primary control line 120 between the first downhole device 170 (e.g., [Fig.lB]) and the second downhole device 180 ([Fig.lC]), if necessary.

[0031] Although a number of different embodiments for mechanical switching systems may be used, in the illustrated embodiment, a sliding sleeve 172 of the first downhole device 170 has a magnetic target 174 thereon. Similarly, the switching system 190b has an associated magnetic target 192 therein, e.g., coupled to the mechanically activated switch 191 (e.g., two or more magnetic characteristics). In at least one embodiment, at least one of the magnetic target 174 or the magnetic target 192 is a magnet (e.g., a permanent magnet or an electromagnet). Further, the switching system 190b may include an insulator 193 separating the first output and the second output. Accordingly, the associated magnetic target 192 will couple to (e.g., decouple from) the magnetic target 174 to switch power between the first downhole device 170 and the second downhole device 180, in this case when the sliding sleeve 172 moves, as shown in 1B and 1C. In at least one embodiment, the sliding sleeve 172 is configured to move when the second downhole device 180 is inserted into the hole.Again, while one or more magnetic targets 174 are illustrated in Figures 1B and 1C for shifting the switch, in one or more other embodiments, the switches are directly shifted as opposed to magnetically shifted.

[0032] Although not illustrated in Figures 1B and 1C, another embodiment may exist in which a reed switch is employed to switch between the first downhole device 170 and the second downhole device 180. In such an embodiment, one or more of the magnetic targets 192 could be exchanged for a reed switch. Thus, when the magnetic target 174 passes over the reed switch, the reed switch will switch power between the first downhole device 170 and the second downhole device 180. In at least one embodiment, one or more of the reed switches are single pole single throw reed switches and / or single pole double throw reed switches. Those skilled in the art understand how such reed switches would be configured to achieve the desires set forth herein.

[0033] Turning now to Figures 1D and 1E, an embodiment of a switching system 190d designed, manufactured, and / or operated is illustrated in accordance with one or more embodiments of the disclosure, as it might be used in the well system 100 of [Fig. 1A]. The switching system 190d, in the illustrated embodiment, is an electrical switching system, for example, comprising an electrically activated switch. In the illustrated embodiment, the switching system 190d comprises two or more oppositely oriented diodes 195a, 195b coupled between the primary control line 120 and each of the first downhole device 170 and the second downhole device 180, respectively. The term "diode," as used herein, includes all electronic components that have asymmetric conductance, including semiconductor diodes, thermocouple diodes, and thermocouple diodes. ionic and multi-chip modules that have asymmetric conductance. Thus, for example, if a positive voltage is applied to the primary control line 120, the first diode 195a would allow current 197 to flow through and thus establish a closed circuit, and thus the first downhole device 170 would be powered. However, the second diode 195b would not allow current 197 to flow through and thus establish an open circuit, and thus the second downhole device 180 would not be powered. In contrast, if a negative voltage is applied to the primary control line 120, the first diode 195a would not allow current 197 to flow through and thus establish an open circuit, and thus the first downhole device 170 would not be powered.However, the second diode 195b would allow the current 197 to pass through and thus establish a closed circuit, and thus the second downhole device 180 would be powered. Thus, by switching the voltage between a positive voltage (e.g., a predefined positive voltage) and a negative voltage (e.g., a predefined negative voltage), the switching system 190d powers different devices among the first downhole device 170 and the second downhole device 180.

[0034] Turning now to Figures 1F and 1G, an embodiment of a switching system 190f designed, manufactured, and / or operated is illustrated in accordance with one or more embodiments of the disclosure, as it might be used in the well system 100 of [Fig. 1A]. The switching system 190f, in the illustrated embodiment, is an electrical switching system. In the illustrated embodiment, the switching system 190f includes low frequency / high frequency filters coupled between the electrical control line 120 and the first downhole device 170, and / or high frequency / low frequency filters coupled between the electrical control line 120 and the second downhole device 180.In this scenario, the low-frequency filters would be configured to pass a low-frequency signal from a power source (e.g., and block the high-frequency signal from a power source), and the high-frequency filters would be configured to pass the high-frequency signal from the power source (e.g., and block the low-frequency signal from the power source). Accordingly, by switching the frequency of the power source, one of the first downhole device 170 or the second downhole device 180 will receive power, while the other of the second downhole device 180 or the first downhole device 170 will not receive power.

[0035] In the embodiment of Figures 1F and 1G, a low frequency filter 196a surrounds the first downhole device 170 and a high frequency filter 196b surrounds the second downhole device 180. Accordingly, as shown in Figures 1F and 1G, the low frequency signal will only feed the first downhole device 170 and the high frequency signal will only power the second downhole device 180. Thus, by switching the frequency of the power source, different devices among the first downhole device 170 and the second downhole device 180 will be powered.

[0036] It should be noted that the terms "low frequency signal" and "high frequency signal" are relative to each other and are not limited by specific values. However, in at least one embodiment, the low frequency signal is less than 100 Hz and the high frequency signal is greater than 100 Hz, and even in another embodiment greater than 10,000 Hz. In yet another embodiment, the frequency of the high frequency signal is at least 50% higher (e.g., at least 50% more cycles per second) than the frequency of the low frequency signal. In yet another embodiment, a DC signal is a subset of a low frequency signal.

[0037] It should also be noted that the term "frequency filter" includes all known or later discovered frequency filters that could be used for the purposes disclosed herein. For example, the frequency filter could be a continuous-time linear filter, such as an elliptical filter, a Butterworth filter, or a Chebyshev filter, among others. The frequency filter may also be an analog filter or a digital filter, and may be a passive or active filter. In one exemplary embodiment, the frequency filter is a passive analog filter. In yet another embodiment, the frequency filter may include nonlinear electrical components, such as one or more electrical switches (e.g., such as a field-effect transistor or FET) and AC-to-DC power converters.In some embodiments, the frequency filter will induce the opening or closing of the electrical switch based on the frequency content of the input signal. In another embodiment, the output of the high-pass frequency filter is converted to a DC signal with an AC to DC converter. In other words, in at least this embodiment, electrical power will only be delivered when the input signal is a high-frequency signal. However, the electrical power that is delivered to the load 170, in this embodiment, will consist of DC power.

[0038] In at least one embodiment, the first downhole device 170 is a sensor and the second downhole device 180 is a safety valve, such as a WLRSV. In at least this embodiment, it is desired to continue to power and / or communicate with the sensor even if the second downhole device 180 (e.g., the WLRSV) is installed, and thus a frequency filter (e.g., a high-frequency filter) could be installed with the sensor. Accordingly, in this embodiment, a first signal comprising a power DC would be used to power the sensor, and when the second downhole device 180 (e.g., the WLRSV) is installed, the first signal would be switched to a second signal comprising DC power and AC power, so that both the second downhole device 180 (e.g., the WLRSV) and the sensor are powered. This approach can be used when separate power cables are employed for the TRSV and the sensor (e.g., a downhole pressure / temperature sensor), and it is necessary to step down and supply power to the WLRSV. Greater reliability can be achieved in this embodiment, since the second downhole device 180 (e.g., the WLRSV) receives power along the same electrical control line as the sensor.

[0039] It should further be noted that, although the embodiment of Figures 1F and 1G only utilize two downhole devices (e.g., first downhole device 170 and second downhole device 180), and thus two frequency filters (e.g., low frequency filter 196a and high frequency filter 196b), other embodiments may exist in which more than two downhole devices and more than two frequency filters are employed. For example, another embodiment could exist in which the downhole tool includes first, second, and third downhole devices, as well as a low frequency filter, a mid-frequency filter, and a high-frequency filter to achieve the same objective as disclosed above. This idea could be extended to any number of downhole devices and frequency filters.

[0040] Turning now to Figures 1H and II, an embodiment of a switching system 190h designed, manufactured, and / or operated is illustrated in accordance with one or more embodiments of the disclosure, as it might be used in the well system 100 of [Fig. 1A]. In the embodiment of Figures 1H and II, some (e.g., pairs) of low-frequency filters 196a surround the second downhole device 180 and some (e.g., pairs) of high-frequency filters 196b surround the first downhole device 170. Accordingly, as shown in Figures 1H and II, a low-frequency signal will only feed the second downhole device 180 and a high-frequency signal will only feed the first downhole device 170.Thus, by switching the frequency of the power source, one of the first downhole device 170 and the second downhole device 180 will be powered. Further, although the embodiment of Figures 1H and II employs some (e.g., pairs) of low frequency filters 196a surrounding the first downhole device 170 or high frequency filters 196b, and some (e.g., pairs) of low frequency filters 196a surrounding the first downhole device 170 or high frequency filters 196b, pairs) of high frequency filters 196b or low frequency filters 196a surrounding the second downhole device 180, other embodiments exist in which a single low frequency filter 196a and / or a single high frequency filter 196b is positioned on one side or the other of the first downhole device 170 or the second downhole device 180 (e.g., as shown in Figures 1F and 1G). Furthermore, not all embodiments require both the high frequency filter 196b and the low frequency filter 196a, and thus certain circumstances may arise in which a single frequency filter (e.g., either the high frequency filter 196b or the low frequency filter 196a) is used, but not both.For example, the first output may be coupled to the first electrical component of the first downhole device via the frequency filter or the second output may be coupled to the second electrical component of the second downhole device via the frequency filter, the frequency filter being configured to switch power between the electrical control line and the first downhole device or the electrical control line and the second downhole device based on switching a signal from the power source.

[0041] It should be noted that the embodiments of Figures 1F-11F employ electromagnetic coupling to power the first downhole device 170 and the second downhole device 180. However, other embodiments could be used in which direct electrical coupling powers the first downhole device 170 and the second downhole device 180. In yet another embodiment, a combination of electromagnetic coupling and direct coupling could be employed to power the first downhole device 170 and the second downhole device 180.

[0042] Turning now to Figures 1J and 1K, an embodiment of a switching system 190j designed, manufactured, and / or operated is illustrated in accordance with one or more embodiments of the disclosure, as it might be used in the well system 100 of [Fig. 1A]. The switching system 190j contains a magnetically activated switch 198. In one embodiment, the magnetically activated switch 198 is a reed switch, as shown in Figures 1J and 1K. When no magnetic field is subjected to the magnetically activated switch 198, as shown in [Fig. U], then the contact 199 in the reed switch is biased (e.g., intrinsically polarized) toward an electrical connection with the first downhole device 170, and thus power (e.g., electrical current) can flow to that tool.When a magnetic field is subjected to the magnetically activated switch 198, as shown in [Fig.lK], then the contact 199 in the reed switch is . polarized (e.g., mechanically polarized) to an electrical connection with the second downhole device 180, and thus power (e.g., electric current) can flow to that tool. For example, in [Fig. 1K], the magnetic target 174 creates a magnetic attraction that attracts the contact 199 to an electrical connection with the second downhole device 180 and thus power (e.g., electric current) can flow to that tool. The magnetically activated switch 198 may employ first and second reed switches rather than the two-throw switch that is shown, the second reed switch being configured to operate in conjunction with the first reed switch to switch power between the primary control line and the first downhole device and the primary control line and the second downhole device.One advantage of the reed switch is that it is a mechanically activated switch and does not contain any electronic components. As an alternative embodiment, the mechanically activated switch 198 could be a tunnel magnetoresistance (TMR) switch. A TMR switch contains a magnetic tunnel junction where the resistance of the junction varies depending on the magnetic field. The TMR switch varies between high resistance (switch open) and low resistance (switch closed) with an applied magnetic field.

[0043] Turning to [Fig.11], a table illustrating various ways in which an operator can power the TRSV and / or the WLRSV is shown, including using a single primary control line, two dedicated control lines, a single primary control line with a switch, as well as a single primary control line with low-pass / high-pass filters.

[0044] Turning now to Figures 2A-2F, an embodiment of a downhole device is illustrated, comprising a safety valve 200 designed, manufactured and / or operated in accordance with one or more embodiments of the disclosure, such that it could utilize the first, second and third portions of the WLRSV, as discussed above. Figures 2A-2C illustrate various views of the safety valve 200 in a first closed position, its electromagnetic assembly unpowered and one or more magnetic targets decoupled from each other. [Fig. 2D] illustrates the safety valve 200 of Figures 2A-2C in a second closed position with power (DC power in this embodiment) supplied to the electromagnetic assembly, thereby coupling the electromagnetic assembly and the one or more magnetic targets together. [Fig. 2E] illustrates the safety valve 200 of [Fig.2D] now in an open position, the energized (DC powered) electromagnetic assembly and one or more magnetic targets remaining magnetically coupled (e.g., fixedly coupled) to each other. [Fig.2F] illustrates . the safety valve 200 of [Fig.2E] after the power (DC power) has been cut off to the electromagnetic assembly, and thus the safety valve 200 returns to the first closed position. In yet another embodiment, the safety valve 200 may be returned to the first closed position indirectly, for example if an electrical logic circuit determines that the electrical power has been interrupted and triggers a closure of the safety valve 200.

[0045] Referring initially to Figures 2A-2C, the safety valve 200 is illustrated in the first closed position. The safety valve 200, in one or more embodiments, may include an outer housing 224 (e.g., a tubular housing, a wellbore pipe, etc.) containing a central bore 225 therein, wherein components of the safety valve 200 may be disposed within the central bore 225. An upper valve assembly 234 (e.g., also the axially fixed magnetic target portion in this embodiment) may be attached to the outer housing 224, and may further include one or more sealing members 223, such that fluid communication from a lower section 202 to an upper section 203 is prevented.

[0046] A sleeve 226 may be attached between the upper valve assembly 234 and the lower valve assembly 216. A bore flow management actuator 240 may be disposed within the sleeve 226. The bore flow management actuator 240 may include a translation sleeve 222 and a flow tube main body 208. A flow path 214 may be defined by an interior of the flow tube main body 208. As illustrated in FIGS. 2A-2C, the flow path 214 may extend from an interior of a conduit 206 through an interior of the flow tube main body 208. As discussed in more detail below, when the safety valve 200 is in an open position, the flow path 214 may extend from an interior of the conduit 206 through an interior of the main flow tube body 208 and further into the lower section 202.

[0047] The safety valve 200 may further include a power spring 210 disposed between the lower valve assembly 216 and a translation sleeve shoulder 218. As illustrated in FIGS. 2A-2C, the translation sleeve shoulder 218 and a flow tube shoulder 232 may be in contact when the safety valve 200 is in the first closed position. The power spring 210 may provide a positive spring force against the translation sleeve shoulder 218, which may maintain the flow tube main body 208 in a first position. The power spring 210 may also provide a positive spring force to return the flow tube main body 208 to a first closed position. flow tube 208 and translation sleeve 222 to the first position (e.g., from a second position), as will be explained below.

[0048] The safety valve 200 may further include a nose spring 212 disposed between a translation sleeve assembly 230 and the flow tube shoulder 232. The translation sleeve assembly 230 may be disposed between and attached to a piston 220 and the translation sleeve 222. The power spring 210 and the nose spring 212 are shown as coil springs in Figures 2A-2F. However, the power spring 210 and the nose spring 212 may include any type of spring and remain within the scope of the present disclosure, such as coil springs, wave springs, or fluid springs, among others.

[0049] In the illustrated embodiment, the translation sleeve assembly 230 may allow application of a force to a distal end of the piston 220 to be transferred into the translation sleeve 222. A force may be applied to the distal end of the piston 220 via fluid communication from a channel 228 through a port 242. A force applied to the piston 220 may move the translation sleeve 222 from a first position to a second position. The nose spring 212 may provide a positive spring force against the translation sleeve assembly 230 and the flow tube shoulder 232, which may return the translation sleeve 222 from the second position to the first position, as will be discussed in more detail below.

[0050] In the first closed position, the translation sleeve 222 and the flow tube main body 208 are positioned such that the translation sleeve shoulder 218 and the flow tube shoulder 232 are in contact and the power spring 210 and the nose spring 212 are in an extended position. In the first closed position, the translation sleeve 222 can be considered to be in a first position and the flow tube main body 208 can be considered to be in a first position.

[0051] In at least one embodiment, the bore flow management actuator 240 is configured to slide from a first initial state to a first subsequent state to move a valve closure mechanism 204 between a first closed state and a first open state. In the first closed state, the valve closure mechanism 204 may isolate the lower section 202 from the flow tube main body 208. When the valve closure mechanism 204 is in a first closed state, as in FIGS. 2A-2C, the valve closure mechanism 204 may prevent formation fluids and pressure from flowing into the flow tube main body 208 from the lower section 202. Although FIGS. 2A-2C illustrate the valve closure mechanism 204 as as a flap valve, the valve closure mechanism 204 may be any suitable valve type such as a flap valve, a linear gate valve, or a ball valve, for example. As will be illustrated in more detail below, the valve closure mechanism 204 may be actuated in a first open state to allow formation fluids to flow from the lower section 202 through the flow path 214 (e.g., defined by the lower section 202, an interior of the flow tube main body 208, and an interior of the conduit 206).

[0052] When the safety valve 200 is in the first closed position, no amount of differential pressure across the valve closure mechanism 204 will allow formation fluids to flow from the lower section 202 into the flow path 214. In the first closed position, the safety valve 200 will only allow fluid flow from the conduit 206 into the lower section 202, but not from the lower section 202 into the conduit 206. In the event that the pressure in the conduit 206 is increased, the valve closure mechanism 204 will remain in the closed position until the pressure in the conduit 206 is increased above the pressure in the lower section 202 plus the closing pressure provided by the valve closure mechanism spring 205, sometimes referred to herein as the valve opening pressure.When the valve opening pressure is reached, the valve closure mechanism 204 may open and allow fluid communication from the conduit 206 into the lower section 202. In this manner, treatment fluids such as surfactants, scale inhibitors, hydrate treatments, and other suitable treatment fluids may be introduced into the subterranean formation. The configuration of the safety valve 200 may allow treatment fluids to be pumped from a surface, such as a wellhead, into the subterranean formation without actuating a control line or balance line to open the valve.Once the pressure in conduit 206 is decreased below the valve opening pressure, the valve closing mechanism spring 205 will return the valve closing mechanism 204 to the closed position, and thus flow from conduit 206 into lower section 202 will cease. When the valve closing mechanism 204 has returned to the closed position, flow from lower section 202 into flow path 214 will be prevented. If a pressure differential across the valve closing mechanism 204 is reversed, such that the pressure in lower section 202 is greater than a pressure in conduit 206, the valve closing mechanism 204 will remain in a closed position, such that fluids in lower section 202 are prevented from flowing into conduit 206.

[0053] In the illustrated embodiment, the safety valve 200 includes a first portion 250, a second portion 260 (e.g., the second portion 260 may include the features disclosed in the paragraph above, e.g., the features located between the upper valve assembly 234 and the valve closure mechanism 204, and more particularly the bore flow management actuator 240 and the valve closure mechanism 204), and a third portion 270. As noted above, in at least one embodiment, the first portion 250 has a minimum inside diameter of first portion (IDJ) and is inserted into the bore with the TRSV, and the second portion 260 and third portion 270 are inserted into the bore after the TRSV is no longer functioning properly and / or has failed.For example, in at least one embodiment, the second part 260 has a second part maximum outer diameter (OD2), the second part maximum outer diameter (OD2) being less than the first part minimum inner diameter (IDi) such that the second part 260 can be introduced into the hole after the first part 250. Further, the third part 270 can be introduced into the hole in a separate step after the second part 260.

[0054] In one or more embodiments, the first portion 250 includes a fluid isolation sleeve 252, and an electromagnetic assembly 254 (e.g., including one or more coils). The one or more coils, in one or more embodiments, may include an insulated electrical wire that forms loops around a common axis to produce a magnetic field when a current passes through the wire. The number of loops may vary, but in at least one embodiment, the number of loops is between 10 and 500,000, or even between 100 and 100,000. In one or more embodiments, the fluid isolation sleeve 252 isolates the electromagnetic assembly 254 from fluid and / or debris within the wellbore. The fluid isolation sleeve 252 may be worn to allow for pressure equalization.In one embodiment, the fluid isolation sleeve 252 is mechanically connected to the electromagnetic assembly 254. In at least one embodiment, the fluid isolation sleeve 252 is a fixed fluid isolation sleeve, and thus does not readily move once positioned downhole. For example, the fluid isolation sleeve 252 could comprise a composite, plastic, ceramic, aluminum, stainless steel, or other non-ferromagnetic material. In another embodiment, the fluid isolation sleeve 252 could comprise a ferromagnetic material, but should be thin enough so as not to divert too much of the magnetic force generated by the electromagnetic assembly 254 from its intended use, as discussed below.

[0055] In one or more embodiments, the second portion 260 includes the flow tube 208 and the valve 204, and may be located below the first portion 250 (e.g., below the fluid isolation sleeve 252 and the electromagnetic assembly 254). The second portion 260 may further include the power spring 210 and / or the nose spring 212, as will be discussed in more detail below. The second portion 260 may further include an axially attached magnetic target portion 246, which again may or may not form a part of the upper valve assembly 234.

[0056] In one or more other embodiments, the third portion 270 includes a mechanical connection apparatus 272 having one or more magnetic targets 274 associated therewith. The one or more magnetic targets 274, in one or more embodiments, are axially aligned with the axially attached magnetic target portion 246 of the second portion 260 and are configured to slide axially relative to the axially attached magnetic target portion 246. The one or more magnetic targets 274, in this embodiment, are configured to magnetically couple to the axially attached magnetic target portion 246 of the second portion 260 when the electromagnetic assembly 254 of the first portion 250 is powered and the two are located in close proximity to each other.Essentially, when the one or more magnetic targets 274 and the axially attached magnetic target portion 246 are positioned in proximity to each other, and the electromagnetic assembly 254 is energized, a magnetic flux with a flux path encircling the electromagnetic assembly 254, one or more magnetic targets 274, and the axially attached magnetic target portion 246 is formed. This magnetic flux and associated flux path maintains the one or more magnetic targets 274 on the axially attached magnetic target portion 246, and would thus maintain the mechanical connection apparatus 272 and the flow tube 208 in the open position when the electromagnetic assembly 254 is energized.

[0057] Referring to [Fig.2D], the safety valve 200 is illustrated in a second closed position. In the second closed position, the translation sleeve 222 may be moved from the first position to a second position, which is relatively closer to the valve closing mechanism 204. The flow tube main body 208 may remain in the first position, or alternatively only slightly downhole relative to the first position. When the safety valve 200 is in the second closed position, both the power spring 210 and the nose spring 212 may be in a compressed state.

[0058] To move the translation sleeve 222 into the second position, the differential pressure across the valve closing mechanism 204 may be increased by lowering the pressure in the conduit 206 or by increasing the pressure in the section lower 202. Lowering the pressure in the conduit 206 or increasing the pressure in the lower section 202 may cause fluid flow from the lower section 202 through the channel 228 defined between the sleeve 226 and the outer housing 224 into the port 242. The port 242 may provide fluid communication into the piston tube 244, whereby the fluid pressure may act on the proximal end of the piston 220. The force exerted by the fluid pressure on the proximal end of the piston 220 may move the piston 220 toward the valve closure mechanism 204 by transferring the force through the piston 220, the translation sleeve assembly 230, and the translation sleeve shoulder 218.The nose spring 212 may provide a spring force against the flow tube shoulder 232 and the translation sleeve assembly 230, and the power spring 210 may provide a spring force against the translation sleeve shoulder 218 and the lower valve assembly 216.

[0059] Although not illustrated in Figures 2A-2F, the flow tube main body 208 may include channels that provide pressure and / or fluid communication between the flow path 214 and an interior of the sleeve 226. Collectively, the spring forces from the power spring 210 and the nose spring 212 may resist movement of the piston 220 until the differential pressure across the valve closure mechanism 204 is increased beyond the spring force provided by the power spring 210 and the nose spring 212. The increase in differential pressure may include a decrease in the pressure in the conduit 206 such that the pressure in the lower section 202 is relatively higher than the pressure in the conduit 206. As the differential pressure across the valve closure mechanism 204 is increased, the differential pressure across the piston 220 also increases.When the differential pressure across the valve closing mechanism 204 is increased beyond the spring force provided by the nose spring 212 and the power spring 210, the nose spring 212 and the power spring 210 may compress and allow the translation sleeve 222 to move to the second position. The differential pressure across the valve closing mechanism 204 may be increased by pumping fluid out of the conduit 206, for example. In the event that the lower section 202 is fluidly coupled to an imperforate section of the pipe or when there is a plug in a conduit 206 fluidly coupled to the lower section 202 that prevents transmission of pressure from the lower section 202 to the piston 220, a pressure differential across the valve closing mechanism 204 may be induced by swelling of the pipe.

[0060] In the second closed position, the safety valve 200 remains secure because no fluid from the lower section 202 can flow into the flow path 214. In the second closed position, no amount of differential pressure across the valve closure mechanism 204, the differential pressure being a relatively higher pressure in the lower section 202 and a relatively lower pressure in the conduit 206, should cause the valve closure mechanism 204 to open to allow fluids from the lower section 202 to flow into the flow path 214, as the pressure from the lower section 202 acts on the valve closure mechanism 204. If the pressure increases in the conduit 206, the differential pressure across the valve closure mechanism 204 decreases and the translation sleeve 222 can return to the first position illustrated in Figures 2A-2C.Unlike conventional safety valves which generally require a control line to provide pressure to actuate a piston to move a translation sleeve, the safety valve 200 may only require pressure provided by the wellbore fluids in the lower section 202 to move the translation sleeve.

[0061] Still referring to [Fig. 2D], the piston 220 may be fixedly attached to the translation sleeve assembly 230. Although illustrated as a single piston in Figures 2A-2F, the piston 220 may comprise a plurality of pistons and remain within the scope of the disclosure.

[0062] As illustrated, when the translation sleeve 222 is moved from the first position to the second position, the piston 220 may also be moved. Before, during, or after the translation sleeve 222 is allowed to move to the second position as described above, the electromagnetic assembly 254 may be energized. The energization of the electromagnetic assembly 254, and the resulting magnetic flux and flux path, may maintain the one or more magnetic targets 274 on the axially fixed magnetic target portion 246. Since the one or more magnetic targets 274 are rigidly coupled to the flow tube 208 (e.g., via the mechanical connection apparatus 272), the flow tube 208 is also maintained in its axial downhole position, as illustrated in [Fig. 2D].

[0063] In Figures 2A-2F, the electromagnetic assembly 254 is shown as a coil circumscribing the tubular member, but there may be any number of coils in any orientation to secure the sliding sleeve 226, and thus the bore flow management actuator 240 in place. The electromagnetic assembly 254 may apply a force in a substantially radial or axial direction, for example. The force applied by the electromagnetic assembly 254 may be any amount of force, including, but not limited to, a force in a range of about 45 Newtons to about 45,000 Newtons. The assembly electromagnetic assembly 254 can provide a means for maintaining the sliding sleeve 226 and the bore flow management actuator 240 at any well depth. Hydraulic systems used in previous wellbore safety valves typically require control and balance lines to actuate and maintain a valve open, which may have pressure limitations. The limitations encountered by hydraulic systems can be overcome using the electromagnetic assembly 254 described herein, as only well pressure is required to open the safety valve 200.Again, when the translation sleeve 222 is in the second position, when the electromagnetic assembly 254 is turned on or off, no amount of differential pressure across the valve closing mechanism 204 will open the valve closing mechanism 204, the differential pressure being a pressure difference between a relatively higher pressure in the section 202 and a relatively lower pressure in the conduit 206.

[0064] Referring to [Fig. 2E], the safety valve 200 is illustrated in an open position. When the safety valve 200 is in the open position, the translation sleeve 222 may be secured in place in the second position, as in FIGS. 2D and 2E, through the force provided by the electromagnetic assembly 254, the force being transferred through the mechanical connection apparatus 272 to the bore flow management actuator 240, for example via the translation sleeve 222. The flow tube main body 208 is illustrated as being axially offset from the first position illustrated in FIGS. 2A-2D to a second position in [Fig. 2E].When the flow tube main body 208 is in the second position, the flow tube shoulder 232 and the translation sleeve shoulder 218 may be in contact and the flow tube main body 208 may have moved the valve closing mechanism 204 into an open position. The nose spring 212 may be in an uncompressed state, while the power spring 210 may be in a compressed state.

[0065] The flow tube main body 208 can be moved from the first position to the second position when the translation sleeve 222 is secured in place in the second position by the electromagnetic assembly 254, as described above. When the translation sleeve 222 is secured in the second position through the force provided by the electromagnetic assembly 254, the nose spring 212 can provide a positive spring force against the flow tube shoulder 232 and the translation sleeve assembly 230. The positive spring force of the nose spring 212 can be transferred through the flow tube main body 208 into the valve closing mechanism 204. The flow tube main body 208 will not move to the second position until the differential pressure across the valve closing mechanism 204 exists and the translation sleeve 222 is fixed in position. The differential pressure can be decreased by pumping into the conduit 206, thereby increasing the pressure in the conduit 206. The pressure can be increased in the conduit 206 until the differential pressure across the valve closing mechanism 204 is decreased to a point where the positive spring force of the nose spring 212 is greater than the differential pressure across the valve closing mechanism 204. Thereafter, the nose spring 212 can extend and move the flow tube main body 208 into the second position by acting on the translation sleeve assembly 230 and the flow tube shoulder 232, which are held in place via the electromagnetic assembly 254 and one or more other features.When the flowtube main body 208 is in the second position, fluids such as oil and gas in the lower section 202 may flow into the flowpath 214 and toward a surface of the wellbore such as a wellhead. The safety valve 200 may remain in the open position defined by the translation sleeve 222 being in the second position and the flowtube main body 208 being in the second position, as long as the electromagnetic assembly 254 remains energized.

[0066] The safety valve 200 may be returned to the first closed position, as illustrated in [Fig. 2F], by de-energizing the electromagnetic assembly 254. As discussed previously, the electromagnetic assembly 254 may secure the one or more magnetic targets 274 and the flow tube 208 in place in the second position when the electromagnetic assembly 254 remains energized. When the electromagnetic assembly 254 is de-energized, the one or more magnetic targets 274 and the flow tube 208 may no longer be secured in place. The electromagnetic assembly 254 may alternate the winding direction of the coil. Alternating the winding direction will cause the magnetic field directions to alternate. The result is multiple magnetic reversals in the coils of the electromagnetic assembly 254 that would magnetically connect to the one or more magnetic targets 274.The power spring 210 may provide a positive spring force against the lower valve assembly 216, moving the sleeve shoulder 218 and the flow tube shoulder 232 up the hole. The positive spring force of the power spring 210 may axially move the translation sleeve 222 to the first position and the flow tube main body 208 to the first position, thereby returning the safety valve 200 to the first closed position shown in Figures 2A-2C, and 2F. The positive spring force of the power spring 210 may also axially move the one or more magnetic targets 274 to the position shown in Figures 2A-2C, and 2F. Figures 2A-2C and 2F, transmitting the positive spring force through the mechanical connecting apparatus 272.

[0067] Turning now to Figures 3A-3D, various views are illustrated of a safety valve 300 designed, manufactured, and / or operated in accordance with one or more alternative embodiments of the disclosure. The safety valve 300 of Figures 3A-3D is similar in many respects to the safety valve 200 of Figures 2A-2C. Accordingly, like reference numerals have been used to illustrate similar, if not identical, features. Figures 3A-3D illustrate the safety valve 300 in its operational state, such that each of the first portion 250, the second portion 260, and the third portion 270 are coupled together and secured within the tubular member. For example, as illustrated, a locking mechanism 362 of the second portion 260 axially secures the second portion 260 within the tubular member.Further, the mechanical connection apparatus 272 of the third portion 270 axially secures the one or more magnetic targets 274 of the third portion 270 to the bore flow management actuator 240 (e.g., the translation sleeve assembly 230) of the second portion 260. Thus, any axial movement of the flow tube 208, as discussed above, will result in similar axial movement of the one or more magnetic targets 274. Further, the electromagnetic assembly 254, in the illustrated embodiment, is located in a pocket 310 in a safety valve subassembly 320. As a result of this embodiment, the fluid isolation sleeve 252 separates the electromagnetic assembly 254 located in the pocket 310 from the mechanical connection apparatus 272.

[0068] Turning now to Figures 4A-9D, various different installation and / or operating states are illustrated, each with various different views, of a safety valve 400 designed, manufactured and / or operated in accordance with one or more alternative embodiments of the disclosure. The safety valve 400 of Figures 4A-9D is similar in many respects to the safety valve 300 of Figures 3A-3D. Accordingly, like reference numerals have been used to illustrate similar, or even identical, features.

[0069] Figures 4A-4D illustrate the safety valve 400 in its state of insertion into the initial hole, and thus at this stage, the safety valve 400 comprises only a safety valve subassembly 420 coupled to the TRSV 410. The safety valve subassembly 420, in this embodiment, comprises the first part 250 (e.g., having the fluid isolation sleeve 252 and the electromagnetic assembly 254). In contrast, Figures 5A-5D illustrate the safety valve 400 after the TRSV 410 no longer functions properly and / or has failed. Accordingly, the safety valve 400 of Figures 5A-5D comprises further the second part 260, for example including the flow tube main body 208 and the valve closing mechanism 204.

[0070] Turning now to Figures 6A-6D, the safety valve 400 of Figures 5A-5D is illustrated after insertion of the third part 270 therein. In the illustrated embodiment, the third portion 270 includes the mechanical connection apparatus 272 and one or more magnetic targets 274. The third portion 270, in this embodiment, axially couples to the flow tube 208 of the second portion 260. Accordingly, in the embodiment of Figures 6A-6D, the third portion 270 is now coupled to the bore flow management actuator 240 (e.g., the translation sleeve assembly 230) of the second portion 260, and thus the bore flow management actuator 240 (e.g., the translation sleeve assembly 230) and the one or more magnetic targets 274 are axially secured to each other (e.g., via the mechanical connection apparatus 272).The progression of Figures 4A-6D illustrates how the safety valve 400 could be installed in accordance with one or more embodiments of the disclosure.

[0071] Turning now to Figures 7A-9D, certain embodiments are illustrated regarding how the safety valve 400 of Figures 6A-6D may be operated. More specifically, Figures 7A-7D illustrate the safety valve 400 of Figures 6A-6D when the safety valve 400 has tube pressure under the valve closing mechanism 204. In this case, the pressure under the valve closing mechanism 204 has compressed the power spring 210 and the nose spring 212, and in doing so, may have slightly moved the flow tube 208 and the associated mechanical connection apparatus 272 downhole. For example, the flow tube 208 has moved downhole and contacted the valve closing mechanism 204.

[0072] Turning now to Figures 8A-8D, the safety valve 400 of Figures 7A-7D is illustrated once the pressure is balanced across the valve closing mechanism 204, and thus the flow tube 208 is allowed to move axially downward to open the valve closing mechanism 204. At this point, the one or more magnetic targets 274 are positioned proximate the axially attached magnetic target portion 246. If and / or when the electromagnetic assembly 254 is energized, the electromagnetic assembly 254 will form the magnetic flux and flux path 810 with the axially attached magnetic target portion 246 that will keep the one or more magnetic targets 274 engaged with the axially attached magnetic target portion 246, and thus maintain the flow tube 208 in this open state.

[0073] Turning now to Figures 9A-9D, the safety valve 400 of Figures 8A-8D is illustrated after the electromagnetic assembly 254 has lost power, and thus the power spring 210 of the second part 260 pushes the flow tube main body 208 up the hole, allowing the valve closing mechanism 204 to close.
