    CROSS REFERENCE TO RELATED REQUESTS
    [0001] This order contains a matter related to the subject of copending orders, which are attributed to the same assignee of this order, Baker Hudges Incorporated of Houston, Texas. The orders listed below are incorporated by reference in their entirety:
    [0002] U.S. Patent Application Power of Attorney Document No. 274- 49265-US, entitled MODULAR VALVE BODY AND METHOD OF MAKING; and
    [0003] U.S. Patent Application Power of Attorney Document No. 274- 49268-US, entitled TUBULAR VALVING SYSTEM AND METHOD. BACKGROUND
    [0004] Tubular valves that control orifice obstruction, which fluidly connect a hole in a tubular to a tubular exterior, are commonly used in a number of industries including the downhole completion industry. Such valves are implanted in boreholes to control the flow of fluid in both directions, from the inside of the tubular as well as from the outside to the inside of the tubular, through the orifices. The remote control of these valves provides advantages in operational efficiency, in comparison with the valves that require active intervention actuation, and have thus become quite popular. Remotely controlled valves, however, can malfunction. The costs associated with removing valves from the borehole to repair or replace the valve, in addition to the cost of lost production while the well is not producing, are some of the concerns associated with using these valves. Systems and methods that overcome the preceding concerns will be well received in the art. BRIEF DESCRIPTION
    [0005] Here, a tubular valve system is described. The system includes a tubular, a primary actuable valve to control the obstruction of at least one orifice by fluidly connecting an inner tubular hole with an outer of the tubular, and an actuable contingency valve to control the obstruction of at least one orifice connecting fluidly the inner hole with the outside of the tubular.
    [0006] Still described here is a method of arranging valves in a tubular. The method includes actively actuating a primary valve arranged in a tubular, and maintaining a contingency valve arranged in the tubular in reserve. BRIEF DESCRIPTION OF THE DRAWINGS
    [0007] The following descriptions should not be considered limiting in any way. With reference to the accompanying drawings, similar elements are numbered in a similar way: figure 1 represents a partial cross-sectional view of a tubular valve system described here with the primary valve open and the contingency valve closed; figure 2 represents a perspective view of the tubular valve system of figure 1; figure 3 represents a partial cross-sectional view of the tubular valve system of figure 1 with the primary valve closed and the contingency valve open; figure 4 represents a partial cross-sectional view of an alternating tubular valve system described here with the primary valve closed and the contingency valve closed; and figure 5 represents a partial cross-sectional view of the tubular valve system of figure 4 with the primary valve open and the contingency valve open. DETAILED DESCRIPTION
    [0008] A detailed description of one or more modalities of the described apparatus and method are presented by way of example and not limitation with reference to the figures.
    [0009] Referring to figure 1, one embodiment of a tubular valve system described here is generally illustrated at 10. The valve system 10 includes a tubular 14 with a primary valve 18 and a contingency valve 22 arranged therein. . The tubular 14 includes at least one first orifice 26 and at least a second orifice 30 that fluidly connect an inner hole 34 of the tubular 14 with the outer 38 of the tubular 14. The primary valve 18 is configured to control the obstruction of the first orifice 26 while the contingency valve 22 is configured to control the obstruction of at least the second orifice 30, with additional obstruction control of the first orifice 26 by the contingency valve 22 being optional. The contingency valve 22 has a sleeve 40 that is slidably engaged with the tubular 14. In this embodiment, the sleeve 40 is positioned inside the inner hole 34 of the tubular 14. The sleeve 40 is movable with respect to the tubular 14 such that the movement of the glove 40 can completely obstruct the second orifice 30. The glove 40 can be passive so that it is moved by mechanical engagement with it by a displacement tool (not shown), for example. Additionally, an alternating actuator such as an actuator that uses an atmospheric chamber that is disassembled during actuation could displace the sleeve 40.
    [00010] In this embodiment, the primary valve 18 is an actively controlled valve and as such is configured to be controlled remotely, as will be described below. The foregoing construction allows an operator to control primary valve 18 and directly control contingency valve 22. As such, primary valve 18 can be used by an operator to control the flow between inner hole 34 and outer 30 indefinitely, while maintaining the contingency valve 22 in reserve. The contingency valve 22 can be employed to control the flow between the inner hole 34 and the outer 38 at any time, including when the primary valve 18 fails to operate properly due to contamination jamming, for example.
    [00011] The primary valve 18, in this embodiment, includes an elongated member 42 with a bore 46 that extends longitudinally therethrough. A first orifice 50 and a second orifice 54 in the elongate member 42 align with the first orifice 26 and the second orifice 30 in the tubular 14 and fluidly connect with the hole 46. As such, both orifices 26 and 30 are in communication fluid with the outside 38 through holes 50 and 54 and hole 46. Seals 58 and 62, illustrated here as o-rings, seal the elongate member 42 in the tubular 14 to prevent leakage of fluid from the holes 50 and 54 to the outer 38 between the elongate member 42 and the tubular 14. A valve stem 66 is movable within a portion 46A of the hole 46 in sealing engagement with a shoulder 70 of the hole 46, thereby obstructing fluid communication between the inner hole 34 and the outside 38 through the first holes 26 and 50. The valve stem 66 in this view is shown in a position that is not sealed in the shoulder 70 and so the inner hole 34 is in fluid communication with the outside 38 through the first holes 26 and 50.
    [00012] Referring to figure 2, the valve stem 66 in this modality, is actuated by an actuator 74 represented here as an electric actuator, which is controlled by electric energy supplied by a signal carrier 78, represented here as a line electrical supply line or control line. Signal carrier 78 can extend indefinitely in either or both directions along tubular 14 from valve system 10. For example, sign carrier 78 can be extend to a surface in applications where the valve 10 is implanted inside a well (not shown) in a land formation to allow remote control operation of the valve system 10 from the surface. Other embodiments may use alternating actuators 74 to actuate primary valve 18, such as a hydraulic actuator (not shown) that can be supplied with hydraulic power through a signal carrier 78 that includes fluid supply lines.
    [00013] Referring again to figure 1, the sleeve 40 of the contingency valve 22 is illustrated in this view in a position that completely obstructs the second holes 30 and 54. A pair of seals 82, shown here as o-rings, seal sliding the walls 84 of the sleeve 40 on the walls 86 of the tubular 14 on each longitudinal side of the second hole 30. At least one second hole 90 through the walls 84 of the sleeve 40, in this view, the location is shown longitudinally outside both seals 82 and is therefore fluidly isolated from the second orifices 30 and 54, and therefore keeps the contingency valve 22 in a closed position.
    [00014] Referring to figure 3, sleeve 40, in this view, is illustrated in a position such that the second hole 90 is longitudinally aligned with the second holes 30 and 54 and thus fluidly connects the inner hole 34 with the outside 38 keeping the contingency valve 22 in an open position. A recess 92 defined by a portion of the sleeve 40 having a reduced radial dimension, is longitudinally aligned with the second orifice 90 to create an annular space 93 between the sleeve 40 and the tubular 14 to allow fluid to flow in the annular space 93 between the hair minus a second orifice 90 and the second orifice 30 when the second orifice 90 is longitudinally aligned with the second orifice 30.
    [00015] The glove 40, in this embodiment, also includes an optional clamp 94 with clamp fingers 98 that are orientably interlockable with a pair of recesses 102 formed on the walls 86 of the tubular 14. This engagement discourages the unintentional movement of the glove 40 keeping the glove positively in one of the positions defined by the engagement of the clamp fingers 98 within the recesses 102. Although the recesses 102 in this embodiment are located to keep the glove 40 both to completely obstruct the second hole 30 with the glove 40 and to leave the second orifice 30 completely open to the second orifice 90. A profile 106 also formed in the walls 84 of the sleeve 40 provides a detail that is interlockable with a sliding tool (not shown) for easy positive engagement between the displacement tool and the sleeve 40 to facilitate the movement of the glove 40.
    [00016] An optional collar 110 with aspects similar to those of sleeve 40 can be employed to be mechanically displaced to obstruct the first orifice 26. Dislocating the collar 110 may be desirable in case the valve stem 66 of the primary valve 18 ceases in one open position. Such a malfunction would present a permanent fluid connection between the inner hole 34 and the outer 38. The collar 110 could then be used to permanently block the first hole 26 to thereby allow control of fluid communication between the inner hole 34 and the outer 38 by means of mechanical displacement of the contingency valve 22 thereafter. The collar 110 is illustrated in figure 1 with a first orifice 114 through the walls 118 thereof being aligned with the first orifice 26, thereby providing fluid communication between the inner hole 34 and the outer 38 through it. A recess 122 defined by a reduced radial dimension of the walls 118 in longitudinal alignment with the first orifice 114 creates an annular space 126 between the collar 110 and the tubular 14 to allow fluid to flow through it between any of the first orifice 114 and the first hole 26.
    [00017] The collar 110 is movable through contact with the sleeve 40 during the movement of the sleeve 40 in the direction of the collar 110. In alternative modalities not shown here, the collar 110 could be moved by direct mechanical engagement with the displacement tool. The clamp fingers 130 in a clamp 134 of the collar 110 are orientably engaged with the recesses 138 in the walls 86 to discourage the unintended movement of the collar 110 with respect to the tubular 14. The seals 142 slidably engage the sealing walls 86 on the walls 118 a longitudinal dimension that crosses at least the longitudinal dimension of the first orifice 26. As such, when the collar 110 is moved to the position shown in figure 3, the deadhead seals 142 effectively fluid the first orifice 26 for the walls 118 between the seals 142 thereby obstructing fluid communication between the inner hole 34 and the outer 38.
    [00018] Referring to figures 4 and 5, an alternate embodiment of a tubular valve system described here is generally illustrated in 210. Due to the similarities between valve system 210 and valve system 10, many items are identical and as such, they are similarly numbered and are not described in detail here again. A primary difference between the two valve systems 210 and 10 is that the valve system 210 has only the first orifice 26 and not the second orifice 54, as they are both included in the valve system 10. The valve system 210, having only the first orifice 26 negates the need for sleeve 40 and collar 110, when they are incorporated into the valve system 10 to selectively close the second orifice 54 and the first orifice 26, respectively. Sleeve 40 in valve system 210 is therefore used to selectively close the first orifice 26 and, as such, valve system 210 does not include collar 54.
    [00019] In figure 4, the first orifice 26, as illustrated, is completely blocked by the contingency valve 222. In contrast, as illustrated in figure 5, the second orifices 90 of sleeve 40 are aligned with the first orifice 26, and the contingency valve 222 does not provide blocking of first orifice 26.
    [00020] While the invention has been described with reference to an exemplary modality or modalities, it will be understood by those skilled in the art that various changes can be made and equivalents can be replaced by elements of the same, without departing from the scope of the invention. In addition, many modifications can be made to adapt a particular or material situation to the teachings of the invention without departing from its essential scope. Therefore, it is intended that the invention is not limited to the particular modality described as the best considered mode for carrying out this invention, but that the invention will include all modalities that are within the scope of the claims. Also, in the drawings and in the description, exemplary modalities of the invention have been described and, although specific terms may have been used, they are, unless otherwise stated, used in a generic and descriptive sense and not for purposes of limitation, the scope of the invention, therefore not being limited. Furthermore, the use of terms first, second, etc., does not indicate any order or importance, but instead the terms first, second, etc., are used to distinguish one element from another. Furthermore, the use of the terms one, one, etc. they do not indicate a quantity limitation, but instead indicate the presence of at least one of the referred item.
