Title: Bridge plug with multiple sealing elements

Description:
TECHNICAL FIELD 
     The present disclosure relates to bridge plugs, and more particularly, to bridge plugs with multiple sealing elements used to form seals in open-hole environments. 
     BACKGROUND 
     Bridge plugs are downhole tools used to seal and isolate the zones downhole of the bridge plug from the zones uphole of the bridge plug. A bridge plug may be permanent or retrievable. Bridge plugs may be used during production or plug and abandon operations. During or prior to production, the bridge plug may be used to seal a downhole zone to prevent water flowing from a water producing formation to the producing zones uphole of the bridge plug. In a plug and abandon operation, the bridge plug is used as plug fundament by forming a seal sufficient to hold a cement such that the cement may set and harden into a permanent cement plug. 
     Bridge plugs use sealing elements to form a seal in the wellbore. These sealing elements expand to contact an adjacent surface, resulting in a seal at the interface of the adjacent sealing surface. In some operations, the sealing element may not form a sufficient seal at the sealing surface interface. For example, in some wellbores a piece of debris may be present on or near the sealing surface, creating an irregular sealing surface shape that cannot be sealed by the bridge plug. As another example, if sealing is desired between coupled conduits, a gap may be present that creates an irregular sealing surface. The sealing element of the bridge plug may be unable to sufficiently seal this gapped area. In addition to irregular sealing surfaces, rough surfaces may also present problems for the sealing elements. For example, the rough surface of an open hole (e.g., an uncased) portion of a wellbore may be too rough to form a seal capable of withstanding the a differential in either direction. As such, the seal may leak which may result in the failure of the zonal isolation or plugging operation. 
     Should the bridge plug leak, and therefore allow flow or pressure to traverse the sealing element, remediation operations may be needed to reseal the wellbore. For example, if a bridge plug is not sufficiently sealed such that a cement plug could be formed thereon. A new bridge plug may have to be set, and another cement plugging operation may need to be conducted to form the desired cement plug. Moreover, multiple bridge plugs may be required for operations in which rough or irregular surfaces may be present, resulting in added time and expense. Lastly, if gaps or other known irregular surfaces or present, an operator may have to place a bridge plug in a less desirable location to reduce the risk of contacting the irregular surface area. Seal leaks and remediation operations can result in a loss of productive time and increased operational expenditures.

     DETAILED DESCRIPTION 
     The present disclosure relates to bridge plugs, and more particularly, to bridge plugs with multiple sealing elements used to form seals in open-hole environments. 
     In the following detailed description of several illustrative examples, reference is made to the accompanying drawings that form a part hereof, and in which is shown by way of illustration specific examples that may be practiced. These examples are described in sufficient detail to enable those skilled in the art to practice them, and it is to be understood that other examples may be utilized and that logical structural, mechanical, electrical, and chemical changes may be made without departing from the spirit or scope of the disclosed examples. To avoid detail not necessary to enable those skilled in the art to practice the examples described herein, the description may omit certain information known to those skilled in the art. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the illustrative examples are defined only by the appended claims. 
     Unless otherwise indicated, all numbers expressing quantities of ingredients, properties such as molecular weight, reaction conditions, and so forth used in the present specification and associated claims are to be understood as being modified in all instances by the term “about.” Accordingly, unless indicated to the contrary, the numerical parameters set forth in the following specification and attached claims are approximations that may vary depending upon the desired properties sought to be obtained by the examples of the present invention. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claim, each numerical parameter should at least be construed in light of the number of reported significant digits and by applying ordinary rounding techniques. It should be noted that when “about” is at the beginning of a numerical list, “about” modifies each number of the numerical list. Further, in some numerical listings of ranges some lower limits listed may be greater than some upper limits listed. One skilled in the art will recognize that the selected subset will require the selection of an upper limit in excess of the selected lower limit. 
     Unless otherwise specified, any use of any form of the terms “connect,” “engage,” “couple,” “attach,” or any other term describing an interaction between elements is not meant to limit the interaction to direct interaction between the elements and may also include indirect interaction between the elements described. Further, any use of any form of the terms “connect,” “engage,” “couple,” “attach,” or any other term describing an interaction between elements includes items integrally formed together without the aid of extraneous fasteners or joining devices. In the following discussion and in the claims, the terms “including” and “comprising” are used in an open-ended fashion, and thus should be interpreted to mean “including, but not limited to”. Unless otherwise indicated, as used throughout this document, “or” does not require mutual exclusivity. 
     The terms uphole and downhole may be used to refer to the location of various components relative to the bottom or end of a well. For example, a first component described as uphole from a second component may be further away from the end of the well than the second component. Similarly, a first component described as being downhole from a second component may be located closer to the end of the well than the second component. 
     The examples described herein comprise a bridge plug having multiple sealing elements that are not immediately adjacent to one another. One of the many potential advantages of the disclosed bridge plug is that the multiple sealing elements may create multiple seals, thereby reducing the risk of leakage across all sealing elements and strengthening the overall sealing of the bridge plug. Another potential advantage of the disclosed bridge plug is that the multiple sealing elements are not located immediately adjacent to each other, as such there is a gap of a defined space between the formed seals. Spacing the sealing elements reduces the risk that the seals may encounter the same irregular surface or obstruction at the sealing surface. This may result in an increased probability of forming a sufficient seal on surfaces that may be difficult to seal. Yet an additional advantage of the disclosed bridge plug is that the multiple sealing elements may be set in the same run. As such, the bridge plug may be used to create multiple seals in one downhole run. One more additional advantage of the disclosed bridge plug is that multiple sealing elements provide an overall larger sealing surface, which may be beneficial for forming seals at rough sealing surfaces, such as those of an open hole environment. Increasing the sealed area increases the seal&#39;s ability to withstand a target differential range in either direction of the seal. 
       FIG. 1  is an orthogonal view of an example bridge plug, generally  5 , illustrated in its run-in-hole configuration. Bridge plug  5  comprises at least two sealing elements,  10 A and  10 B. Sealing elements  10 A and  10 B may comprise the same or different materials. Although only two sealing elements are illustrated, it is to be understood that the bridge plug  5  may comprise more than two sealing elements in some examples, for example, bridge plug  5  may comprise sealing element  10 A, sealing element  10 B, sealing element  10 C, and so on. Sealing elements  10 A and  10 B are disposed on mandrel  15 . Mandrel  15  is an elongated cylindrical structure comprising a metal or metal alloy of sufficient durability and resilience to withstand the wellbore conditions and to allow for setting of the bridge plug  5 . In preferred examples, mandrel  15  is solid and does not possess an inner cavity throughout its length. At the downhole terminal end of bridge plug  5  is disposed bottom cone  20 . Bottom cone  20  is a conically shaped structure of sufficient durability and shape to guide the bridge plug  5  through or past any restriction(s) which may occur in the wellbore and/or tubing that the bridge plug  5  may traverse as it is guided to a desired target location. Bottom cone  20  may comprise any suitable metal or metal alloy. Bottom cone  20  is coupled to mandrel  15  and is adjacent to sealing element  10 B. As discussed below, a setting tool (not illustrated) may be coupled to mandrel  15  and may be used to generate a sufficient linear force to pull the bottom cone  20  or the portion of mandrel  15  coupled to the bottom cone  20  in an uphole direction (i.e., to the left in the illustration). This movement of bottom cone  20  in an uphole direction results in the compression of the sealing element  10 B in its axial direction which induces the expansion of sealing element  10 B in its radial direction. 
     With continued reference to  FIG. 1 , in-between the sealing elements  10 A and  10 B is a spacer  25 . The spacer  25  is used to produce a gap between the seals formed by sealing elements  10 A and  10 B. Spacer  25  is not compressible. As such, the length of spacer  25  determines the length of the gap between the seals formed from sealing elements  10 A and  10 B when they have been set into their sealing configurations. Spacer  25  should be sized sufficiently to reduce the possibility of an obstruction or otherwise irregular surface element from being present at or near the sealing surface of both of the sealing elements  10 A and  10 B when set. For example, if there is a known gap or debris present at or about the desired sealing area, the spacer  25  should be of sufficient length that the gap or debris could not be present at the interface of both formed seals when set. Spacer  25  is an elongated cylindrical structure comprising a metal or metal alloy of sufficient durability and resilience to withstand the wellbore conditions and to allow for setting of the bridge plug  5 . Spacer  25  comprises a void producing an inner diameter sufficient for the mandrel  15  to pass therethrough. As discussed below, a setting tool (not illustrated) may be coupled to mandrel  15  and may be used to generate a sufficient linear force to pull the spacer  25  or the portion of mandrel  15  coupled to the spacer  25  in an uphole direction (i.e., to the left in the illustration). This movement of spacer  25  in an uphole direction results in the compression of the sealing element  10 A in its axial direction which induces the expansion of sealing element  10 A in its radial direction. 
     Although not illustrated, some optional examples of bridge plug  5  may further comprise backups immediately adjacent to both terminal ends of each of the sealing elements  10 A and  10 B. The backups may be angled and/or expandable and may be used to prevent extrusion of sealing elements  10 A and  10 B. These optional backups would be disposed on both terminal ends of spacer  25 . In examples comprising more than two sealing elements, a spacer  25  may be disposed between each pair of sealing elements to provide a gap of sufficient size between each pair of sealing elements (e.g., between sealing elements  10 A and  10 B, between sealing elements  10 B and  10 C, and so on). 
     As illustrated in  FIG. 1 , bridge plug  5  further comprises a plurality of slips  30 , which are disposed towards the uphole terminal end of the bridge plug  5 . The slips  30  are adjacent to a slip cone  35  used to expand the slips  30  radially. Each individual slip  30  comprises an arm-like structure having an outer surface having at least one outwardly extending serration, tooth, ridge, slit, or otherwise any abrasive gripping surface that is sufficient to assist the slips  30  in anchoring the bridge plug  5  to an adjacent surface such as a wellbore wall. The slips  30  may be coupled to the slip cone  35  by a shearable structure or other such mechanism for actuating the expansion of the slips  30  when desired. The shearable structure allows for deformation of the slips  20  as desired and also prevents premature actuation of the slips  30 . The shear force necessary to actuate the slips  30  with the slip cone  35  may be determined by the shear strength of the material of the shearable structure chosen to couple the slips  30  to the slip cone  35 , as would be readily apparent to one of ordinary skill in the art with the benefit of this disclosure. As such, the slip cone  35  may be actuated before any of the sealing elements  10 A and  10 B, allowing the setting sequence of the bridge plug  5  to be controlled and the bridge plug  5  to be successfully anchored in a desired position before the sealing elements  10 A and  10 B are actuated to begin the sealing portion of the operation. 
     In the illustrated example, the slips  30  comprise a deformable metal or metal alloy. After shearing, the slip cone  35  is free to be pressed or pulled against the slips  30  to pressure the slips  30 , inducing the outward expansion of their arm-like structure. An inner surface of the slips  30  may be tapered to complement the outer surface of the slip cone  35 . The slips  30  may continue to expand radially until they engage an adjacent surface. The slips  30  may engage a wall of a wellbore, for example, in an open-hole portion of a wellbore. Alternatively, the slips  30  may engage the inner diameter of a casing or other tubular. Any number of slips  30  may be used to provide sufficient anchoring of the bridge plug  5 . With the benefit of this disclosure, one of ordinary skill in the art would be readily able to determine the amount of slips  30  necessary to sufficiently anchor the bridge plug  5 . 
     As discussed, the slips  30  in the illustrated example comprise a deformable metal or metal alloy to anchor the bridge plug  5 . In this specific example, bridge plug  5  would not be retrievable and would be used for operations such as plug-and-abandon. In an alternative example, the slips  30  may not be deformable. In this alternative example, the slips  30  may comprise hinges allowing the slips  30  to return to the run-in-hole position after expansion into the set-position. The bridge plug  5  of this alternative example would be retrievable and may be used for operations in which temporary zonal isolation, for example, to reduce water production, may be desirable. The hinged slips  30  may be biased towards the axial direction or may be configured to expand and retract upon actuation by the setting tool. 
     Bridge plug  5  further comprises a setting tool coupling  40 . The setting tool coupling  40  is disposed on the uphole terminal end of the mandrel  15 . The setting tool coupling  40  couples the bridge plug  5  to the setting tool to attach bridge plug  5  to the setting tool so that bridge plug  5  may be deployed in a wellbore. For clarity of illustration, a setting tool is not illustrated, but it is to be understood that any setting tool for setting a bridge plug may be used. One example of a sufficient setting tool comprises an electro-mechanical assembly that produces a linear force sufficient for setting or pulling the bridge plug  5 . The setting tool may be coupled to a wireline and lowered into the wellbore with the bridge plug  5  attached. 
       FIG. 2  is an orthogonal view of the example bridge plug  5  of  FIG. 1  illustrated in its anchored configuration. In the illustrated example, a setting tool (not illustrated) may generate a sufficient linear force to shear the shearable structure that had fixed slip cone  35  and slips  30  in the run-in-hole position illustrated in  FIG. 1 . As the shearable structure has been sheared, the slip cone  35  may be pulled, via the pulling of the connected mandrel  15 , in the uphole direction (i.e., to the left-position illustrated in  FIG. 2 ). As the slip cone  35  is pulled to this left-position it presses against the interior surface  30  of the slips  30 , which are tapered as discussed above and acts as a cam to push the slips  30  outward, inducing the radial expansion of the slips  30 . This radial expansion may continue until contact is made with an adjacent surface such as a wellbore wall or the surface of the inner diameter of a conduit such as a tubing or casing. The expanded slips  30  may then engage said adjacent surface with sufficient force to anchor the bridge plug  5  at that specific location. 
     After the slips  30  have anchored the bridge plug  5 , the setting tool may continue to generate a linear force to pull the mandrel  15  to the left-position. Spacer  25  may be pulled to the left position in sequence after the slips  30  have been deployed as described. As spacer  25  is pulled to the left, the sealing element  10 A is compressed in its axial direction, inducing it to expand in its radial direction. This outward expansion away from the center of the bridge plug  5  may continue so long as the seal element  10 A is compressed in its axial direction and until contact is made with an adjacent surface. The spacer  25  may be held in position with the mandrel  15  by a shearable structure having a shear strength greater than that of the shearable structure of the slip cone  35 . As such, the actuation of sealing element  10 A occurs after the bridge plug  5  is anchored by the slips  30 . The shearable structure thus prevents premature actuation of sealing element  10 A and also allows for sealing element  10 A to be set in sequence. 
     Sealing element  10 A expands in its radial direction to make contact with the adjacent surface to be sealed. Upon contact with an adjacent surface, a seal is formed which may be substantially fluid and pressure tight. As such, the bridge plug  5  is now anchored and partially set. 
       FIG. 3  is an orthogonal view of the example bridge plug  5  of  FIGS. 1 and 2  illustrated in its fully-set configuration. In the illustrated example, the setting tool (not illustrated) continues to generate a sufficient linear force to pull the mandrel  15  to the left-position. Bottom cone  20  may be pulled in the uphole direction in sequence after the spacer  25  has been pulled to the left position and the sealing element  10 A has been expanded in the radial direction due to compression in the axial direction. As bottom cone  20  is pulled to the left, the sealing element  10 B is compressed in its axial direction, inducing it to expand in its radial direction. This outward expansion away from the center of the bridge plug  5  may continue so long as the seal element  10 B is compressed in its axial direction and until contact is made with an adjacent surface. The bottom cone  20  may be held in position with the mandrel  15  by a shearable structure having a shear strength greater than that of the shearable structure of the spacer  25 . As such, the actuation of sealing element  10 B occurs after the actuation of sealing element  10 A. The shearable structure thus prevents premature actuation of sealing element  10 B and also allows for sealing element  10 B to be set in sequence. 
     Sealing element  10 B expands in its radial direction to make contact with the adjacent surface to be sealed. Upon contact with an adjacent surface, a seal is formed which may be substantially fluid and pressure tight. As such, the bridge plug  5  is now anchored and fully set as both sealing elements  10 A and  10 B have been actuated and used to form seals in the wellbore. Subsequent operations may now be commenced, for example, a cement may be placed on the set bridge plug  5  to form a cement plug. 
     Although  FIGS. 2 and 3  illustrate actuation of sealing element  10 B after that of sealing element  10 A, it is to be understood that the sealing elements  10 A and  10 B may be actuated in the opposite order if desired. This reverse actuation sequence may be performed by adjusting the shear strength of the shearable structure holding the bottom cone  20  in position with the mandrel  15  to be less than the shear strength of the shearable structure holding the spacer  25  in position with the mandrel  15 . As such, the shearable structure maintaining the position of the bottom cone  20  will shear first when pressured, resulting in actuation of the sealing element  10 B before that of the sealing element  10 A. 
     Moreover, in a further alternative example, the actuation of the sealing elements  10 A and  10 B may be performed near simultaneously. This simultaneous actuation sequence may be performed by adjusting the shear strength of the shearable structure holding the bottom cone  20  in position with the mandrel  15  to be substantially equal with the shear strength of the shearable structure holding the spacer  25  in position with the mandrel  15 . As such, the shearable structure maintaining the position of the bottom cone  20  will shear at roughly the same time as the shearable structure maintaining the position of the spacer  25 . This may result in the simultaneous actuation of sealing elements  10 A and  10 B. 
     With reference to  FIGS. 1-3 , as illustrated, the bridge plug  5  was anchored and fully set in one trip downhole. Multiple seals were formed with only one bridge plug. The seals are sufficiently spaced to reduce the likelihood of poor seal formation from the presence of irregular surfaces and/or rough surfaces. Multiple sealing elements are used to provide sealing redundancy and increase the sealed surface area, reducing the risk of seal failure. 
     It should be clearly understood that the bridge plug  5  of  FIGS. 1-3  is merely one example of an application of the principles of this disclosure in practice, and a wide variety of other examples are possible. Therefore, the scope of this disclosure is not limited at all to the details of  FIG. 1-3  described herein and/or depicted in any of the other FIGURES. 
       FIG. 4  is an isometric illustration of the bridge plug  5  of  FIGS. 1-3  as set in a wellbore  100  having an irregular sealing surface. Wellbore  100  is an uncased portion of a wellbore. It is to be understood that bridge plug  5  may be used in any portion of any wellbore, including a cased or uncased portion. As illustrated, slips  30  have been expanded and engaged wellbore wall  105 . Engagement of slips  30  with wellbore wall  105  anchors the bridge plug  5  in the wellbore  100  as illustrated. Sealing elements  10 A and  10 B were deployed to form a seal in wellbore  100 . The setting tool was then removed after the bridge plug  5  was set. 
     Debris  110  was present in wellbore  100  at the time of setting. Debris  110  creates an irregular sealing surface on wellbore wall  105 . Sealing element  10 A contacted debris  110  as it was radially expanded. The seal formed by sealing element  10 A was thus formed against a sealing surface incorporating at least a portion of debris  110 . The irregular sealing surface may create gaps or other voids in the seal formed by sealing element  10 A. The presence of these voids may render the seal formed by sealing element  10 A to be insufficient, and as such, it may not be substantially fluid and pressure tight. Moreover, even if there are no voids present in the seal, the debris  110  may shift while sealed or otherwise cause a leak in the seal, increasing the risk of seal failure over the length of the operation. 
     With continued reference to  FIG. 4 , sealing element  10 B has radially expanded to form a seal against the wellbore wall  105 . Sealing element  10 B is not adjacent to sealing element  10 A and is spaced a desired distance apart from sealing element  10 A by spacer  25 . This spacing has allowed the seal formed by sealing element  10 B to not contact debris  110 . As such, the seal formed by sealing element  10 B is a substantially fluid and pressure tight seal that comprises a reduced risk of failure as compared with the seal formed by sealing element  10 A. Despite the presence of debris  110  in the seal formed by sealing element  10 A, subsequent wellbore operations may be commenced, as the seal formed by sealing element  10 B is sufficient to hold a cement, restrict water, etc. Therefore, bridge plug  5  may be used to form multiple seals in the wellbore  100  in one trip while minimizing the risk of seal failure due to rough or irregular sealing surfaces. As such, bridge plug  5  may be used to seal areas containing rough or irregular sealing surfaces such as uncased wellbores, mines, and the like. 
     It should be clearly understood that the bridge plug  5  of  FIG. 4  is merely one example of an application of the principles of this disclosure in practice, and a wide variety of other examples are possible. Therefore, the scope of this disclosure is not limited at all to the details of  FIG. 1-3  described herein and/or depicted in any of the other FIGURES. 
       FIG. 5  illustrates the bridge plug  5  after cement  45  has been pumped into the wellbore  100 . Cement  45  may rest and set uphole of the bridge plug  5  as illustrated. 
       FIG. 6  is illustrates bridge plug  5  descending through the bit  50  of a bottom hole assembly. Bridge plug  5  may be introduced into the wellbore  100  through the bit  50  and then lowered to a desired position and actuated as desired. 
       FIG. 7  is illustrates bridge plug  5  isolating a downhole water producing zone  55 . After isolation of the downhole water producing zone  55 . Upstream wellbore operations may be commenced. 
       FIG. 8  is illustrates bridge plug  5  coupled to a setting tool  60 . Setting tool  60  may be any setting tool configured to actuate the bridge plug  5 . 
       FIG. 9  illustrates the spacer  15  coupled to the mandrel  25  with a shearable structure  65 . Spacer  15  moves with mandrel  25  until an applied pressure threshold is exceeded which shears shearable structure  65  and decouples the spacer  15  from the mandrel  25 . 
     The sealing elements (for examples sealing elements  10 A and  10 B) may comprise any elastomeric material sufficient for use in the example bridge plugs disclosed herein. In some optional examples, the sealing elements may also comprise swellable materials. The swellable materials may be elastomeric or non-elastomeric materials. The swellable materials may be swellable in wellbore fluids. For example, the swellable materials may swell due to contact with aqueous or oleaginous fluids. In some examples, the sealing elements may comprise a composite material. The composite material may comprise any combination of swellable and/or non-swellable materials. Examples of the elastomeric materials include, but are not limited to, ethylene propylene diene monomer rubber, nitrile butadiene, styrene butadiene, any butyl rubber (e.g., brominated butyl rubber, chlorinated butyl rubber, etc.), any polyethylene rubber (e.g., chlorinated polyethylene rubber, sulphonated polyethylene, chlor-sulphonated polyethylene, etc.), natural rubber, ethylene propylene monomer rubber, peroxide crosslinked ethylene propylene monomer rubber, sulfur crosslinked ethylene propylene monomer rubber, ethylene vinyl acetate rubber, hydrogenized acrylonitrile-butadiene rubber, acrylonitrile butadiene rubber, carboxylated acrylonitrile butadiene rubber isoprene rubber, carboxylated hydrogenized acrylonitrile-butadiene rubber, chloroprene rubber, neoprene rubber, polynorbornene, tetrafluoroethylene/propylene, polyurethane rubber, epichlorohydrin/ethylene oxide copolymer rubber, silicone rubber, the like, composites thereof, and any combination thereof. 
     The bridge plugs may be used in any wellbore and in any portion of any wellbore as described above, for example, cased, uncased, open hole, horizontal, slanted, vertical, etc. Although not illustrated, it is to be understood that the principles described herein are equally applicable to subsea operations that employ floating or sea-based platforms and rigs without departing from the scope of the disclosure. Moreover, the bridge plugs may also be used in mining operations. For example, the bridge plug may be passed through a core bit and then expanded into an open hole section of a borehole for a mining operation. The bridge plug may then be anchored at a desired location and set by the expansion of the sealing elements. The bridge plug may then seal the borehole of the mining operation, isolating lower zones or allowing for the borehole to be plugged with a cement plug. 
     It is also to be recognized that the disclosed bridge plugs, methods of use, and corresponding systems may also directly or indirectly affect the various downhole equipment and tools that may contact the bridge plugs. Such equipment and tools may include, but are not limited to, wellbore casing, wellbore liner, completion string, insert strings, drill string, coiled tubing, slickline, wireline, drill pipe, drill collars, mud motors, downhole motors and/or pumps, surface-mounted motors and/or pumps, centralizers, turbolizers, scratchers, floats (e.g., shoes, collars, valves, etc.), logging tools and related telemetry equipment, actuators (e.g., electromechanical devices, hydromechanical devices, etc.), sliding sleeves, production sleeves, plugs, screens, filters, flow control devices (e.g., inflow control devices, autonomous inflow control devices, outflow control devices, etc.), couplings (e.g., electro-hydraulic wet connect, dry connect, inductive coupler, etc.), control lines (e.g., electrical, fiber optic, hydraulic, etc.), surveillance lines, drill bits and reamers, sensors or distributed sensors, downhole heat exchangers, valves and corresponding actuation devices, tool seals, packers, cement plugs, bridge plugs, and other wellbore isolation devices, or components, and the like.
