`ONE-PIECE PRODUCTION/ANNULUS BORE STAB WITH
`INTEGRAL FLOW PATHS
`
`2065.018900
`15228
`
`TECHNICAL FIELD
`
`The present disclosed subject matter generally relates to various embodiments of a
`
`one-piece production/annulus bore stab with integral flow paths.
`
`BACKGROUND
`
`A typical wellhead structure for an oil and gas well includes a high-pressure wellhead
`
`housing secured to a low-pressure housing, such as a conductor casing. The wellhead
`
`structure supports various casing strings that extend into the well. One or more casing
`
`hangers are typically landed in the high-pressure wellhead housing, with each casing hanger
`
`being located at the upper end of a string of casing that extends into the well. A tubing
`
`hanger is also typically landed in the wellhead or a tubing head. A string of production
`
`tubing is supported by the tubing hanger. The production tubing extends through the
`
`production casing and provides a path for conveying production fluids from the formation to
`
`the wellhead. The area between the production tubing and the production casing is referred
`
`to as the annulus.
`
`An oil/gas well also typically includes a production tree (also referred to as a
`
`Christmas tree) that is mounted on the high-pressure housing. The production tree includes a
`
`main production bore. Production bore stabs are commonly positioned between the main
`
`production bore of a production tree and the production bore of the tubing hanger so as to
`
`provide a flow passageway between those two production bores. This arrangement permits
`
`the production bore of the production tree and the production bore of the tubing hanger to be
`
`fluidly isolated from other bores and passageways within the completion system.

`
`Figures 1-4 depict various aspects of one illustrative example of a prior art two-piece
`
`production/annulus bore stab 10. Figure 2 is a cross-sectional view of the prior art
`
`production/annulus bore stab 10 taken through the axial length of the production/annulus bore
`
`stab 10. Figures 3 and 4 are transverse cross-sectional views of the production/annulus bore
`
`stab 10 taken where indicated in Figure 1. As shown in these drawings, the prior art
`
`production/annulus bore stab 10 generally comprises an inner production stab body 11, an
`
`outer annulus stab body 12, an annulus T-ring 13, an annulus metal seal 14 and an annulus
`
`seal retainer 15. The production/annulus bore stab 10 also comprises a secondary annulus
`
`spacer 16, a secondary metal seal 17, a spacer 18, a primary metal seal 19 and a primary seal
`
`retainer 20. Also depicted is a set screw 21, a lower head cap screw 22, a set screw 23, a
`
`plurality of upper flow openings 24, a plurality of lower flow openings 25 and a plurality of
`
`flow channels 26. In general, the set screw 21 secures the annulus seal retainer 15 in position
`
`with respect to the outer annulus stab body 12 so as to secure the secondary metal seal 17 in
`
`position. The primary seal retainer 20 is adapted to be threadingly coupled to the inner
`
`production stab body 11 to retain the primary metal seal 19 in position and thereby provide a
`
`seal between an end 12A of the outer annulus stab body 12 and the outer surface 11A of the
`
`inner production stab body 11.
`
`As shown in Figures 3 and 4, the outer surface 11A of the inner production stab body
`
`11 has a plurality of channels or recesses 26 formed therein. When the inner production stab
`
`body 11 is positioned within the outer annulus body 12, a plurality of individual fluid flow
`
`paths 27 are defined between the recesses 26 and the inner surface 12B of the outer annulus
`
`stab body 12. Each of these fluid flow paths 27 is in fluid communication with one of the
`
`upper openings 24 and one of the lower openings 25.

`
`SUMMARY
`
`The following presents a simplified summary of the subject matter disclosed herein in
`
`order to provide a basic understanding of some aspects of the information set forth herein.
`
`This summary is not an exhaustive overview of the disclosed subject matter.
`
`It is not
`
`intended to identify key or critical elements of the disclosed subject matter or to delineate the
`
`scope of various embodiments disclosed herein. Its sole purpose is to present some concepts
`
`in a simplified form as a prelude to the more detailed description that is discussed later.
`
`The present application is generally directed to various embodiments of a one-piece
`
`production/annulus bore stab with integral flow paths. One illustrative production/annulus
`
`bore stab disclosed herein comprises a one-piece body that comprises a first cylindrical outer
`
`surface and a second cylindrical outer surface and a plurality of individual fluid flow paths
`
`defined entirely within the one-piece body. In this illustrative example, each of the individual
`
`fluid flow paths is fluidly isolated from one another with the body and each of the fluid flow
`
`paths comprise a first inlet/outlet at a first end of the fluid flow path that is positioned in the
`
`first cylindrical outer surface and a second inlet/outlet at a second end of the fluid flow path
`
`that is positioned in the second cylindrical outer surface.
`
`BRIEF DESCRIPTION OF THE DRAWINGS

`
`In general, one illustrative embodiment of a novel production/annulus bore stab 100
`
`disclosed herein comprises a unitary, one-piece body 102 with a first end 104 and a second
`
`end 106. The body 102 has an outermost cylindrical surface 102S and an inner cylindrical
`
`surface 102T. Also depicted in Figure 6 are a central bore 105 and an axial centerline 107 of
`
`the one-piece production/annulus bore stab 100. The physical dimensions of the one-piece
`
`body 102, e.g., the axial length 102L, outside diameters, the inside diameter of the one-piece
`
`production/annulus bore stab 100, as well as the radial thickness of the body 102 at various
`
`locations along the axial length 102L, may vary depending upon the particular application.
`
`A plurality of individual and separate flow paths 103 are formed within the body 102.
`
`Each of the flow paths 103 has a first inlet/outlet 103A positioned at a first end (adjacent end
`
`104) of the flow path 103 and a second inlet/outlet 103B that is positioned at a second end
`
`(adjacent end 106) of the fluid flow path 103. The first inlet/outlets 103A are positioned in or
`
`extend through a first cylindrical outer surface 102X of the one-piece body 102, while the
`
`second inlet/outlets 103B are positioned in or extend through a second cylindrical outer
`
`surface 102Y of the one-piece body 102. The outside diameters of the first and second
`
`cylindrical outer surfaces 102X, 102Y, respectively, may be the same or they may be
`
`different from one another. As indicated, in one illustrative example, each of the plurality of
`
`individual fluid flow paths 103 are formed or defined entirely within the one-piece body 102.
`
`Moreover, in one illustrative embodiment, each of the individual fluid flow paths 103 are
`
`Page 6 of 18
`
`Dril-Quip, Exh. 1002, Page 13 of 229
`
`

`

`fluidly isolated from one another within the one-piece body 102. As depicted, in one
`
`illustrative embodiment, each of the plurality of individual flow paths 103 extends for
`
`substantially the entire axial length 102L of the one-piece body102.
`

`
`The routing and configuration of the individual flow paths 103 within the one-piece
`
`body 102 may vary depending upon the particular application. In one particularly illustrative
`
`example, each of the plurality of individual flow paths 103 may comprise an axial length
`
`portion 103X having a centerline 103Y that is substantially parallel to the longitudinal
`
`centerline 107. In other applications, all or part of the one or more of the flow paths 103 may
`
`be oriented in a non-parallel relationship with respect to the longitudinal centerline 107. For
`
`example, at least portions of the flow paths 103 may be curved or otherwise non-linear with
`
`respect to the centerline 107 (or some other reference). Thus, the configuration or positioning
`
`of portions of the flow paths 103 with respect to the longitudinal centerline 107 (or some
`
`other reference) may vary depending upon the particular application.
`
`With continuing reference to Figure 6, in this particular example, each of the fluid
`
`flow paths 103 comprises a first flow path transition region 103S between the axial length
`
`portion 103X and the first inlet/outlet 103A, and a second flow path transition region 103T
`
`between the axial length portion 103X and the second inlet/outlet 103B. As also depicted, a
`
`line 103E extending through a center of the first inlet/outlet 103A and intersecting the flow
`
`path centerline 103Y at a first end of the axial length portion 103X defines a first included
`
`angle 125 that is an obtuse angle. Similarly, a line 103F extending through a center of the
`
`second inlet/outlet 103B and intersecting the flow path centerline 103Y at a second end of the
`
`axial length portion 103X defines a second included angle 127 that is an obtuse angle. In
`
`some applications, the angles 125, 127 may be approximately the same.
`
`In other

`
`applications, the angles 125, 127 may be different from one another. Additionally, the size,
`
`i.e., diameter of the flow paths 103 as well as the number of flow paths 103 may vary
`
`depending upon the particular application. With reference to Figure 7, the illustrative one-
`
`piece production/annulus bore stab 100 disclosed herein comprises thirty-six flow paths 103,
`
`each of which have a diameter of approximately 6.35 mm (0.25 inches).
`
`Figure 10 is a cross-sectional view depicting the engagement and positioning of one
`
`end of the one-piece production/annulus bore stab 100 relative to another item of equipment
`
`114, e.g., a tubing hanger or the valve block of a production tree. Also depicted in Figure 10
`
`is an elastomer seal 120, a seal 122, a seal spacer 124, a seal 126, a seal 128, an elastomer
`
`seal 131 and a seal retaining ring 130 that is threadingly coupled to the body 102. All of the
`
`illustrative seals and spacers depicted in Figure 10 may or may not be present in all
`
`applications. The equipment 114 comprises at least one annulus fluid flow passageway or
`
`path 116 (only one of the annulus fluid fl
