WITH INTERNAL CONTROL LINES

BACKGROUND

[0001] This present disclosure is related to wellbore operations and, more particularly, to sand control screen assemblies that receive, retain, and protect control lines during installation and operation of the sand control screen assembly.

[0002] During hydrocarbon production from subsurface formations, efficient control of the movement of unconsolidated formation particles into the wellbore, such as sand, has always been a pressing concern. Such formation movement commonly occurs during production from completions in loose sandstone or following the hydraulic fracture of a formation. Formation movement can also occur suddenly in the event a section of the wellbore collapses, thereby circulating significant amounts of particulates and fines within the wellbore. Production of these unwanted materials may cause numerous problems in the efficient extraction of oil and gas from subterranean formations. For example, producing formation particles may tend to plug the formation, tubing, and subsurface flow lines. Producing formation particles may also result in the erosion of casing, downhole equipment, and surface equipment. These problems lead to high maintenance costs and unacceptable well downtime.

[0003] Numerous methods have been utilized to control the movement or production of these unconsolidated formation particles during production operations. For example, one or more sand control screen assemblies are commonly included in the completion string to regulate and restrict the movement of formation particles. Such sand control screen assemblies are commonly constructed by installing one or more screen jackets on a perforated base pipe. The screen jackets typically include one or more drainage layers, one or more screen elements such as a wire wrapped screen or single or multi-layer wire mesh screen, and a perforated outer shroud.

[0004] Smart well components are also often installed with sand control screen assemblies to enable the management of downhole equipment and production fluids. Such smart well components can include one or more sensing devices such as temperature sensors, pressure sensors, flow rate sensors, fluid composition measurement devices, or the like. Other smart well components include control mechanisms, such as flow control devices, safety devices, and the like. These smart well systems are typically controlled or communicated with using one or more control lines that may include hydraulic lines, electrical lines, fiber optic bundles, or the like and combination thereof.

[0005] Such control lines are currently clamped to the outer surface of the tubular and the sand screens as the completion assembly is being run into the wellbore. Sand screens often include a support channel to house the control lines on the outside of the sand-screen, but this inevitably increases the outer diameter of the sand screen. In order to accommodate the increased outer diameter of the sand screens, oftentimes a larger wellbore needs to be drilled. Otherwise, the inner flow path of the tubular can be made smaller {i.e., smaller pipe in the center of the sand-screen), but this results in reduced hydrocarbon production.

[0012] This present disclosure is related to wellbore operations and, more particularly, to sand control screen assemblies that receive, retain, and protect control lines during installation and operation of the sand control screen assembly.

[0013] The present disclosure describes solutions to several problems with the use of sand screens and the fiber optic monitoring in conjunction with sand screens. One or more hydraulic conduits may be arranged between the sand screens and the outer surface of the base pipe to enable pressure monitoring and deployment of optical fibers for distributed temperature monitoring in the sand screens. Advantageously, the conduits are able to pass through multiple screen assemblies in a continuous tubular length, thereby providing an instrumented sand screen with minimum mechanical footprint. Where fiber optic cables are employed, the systems and methods disclosed herein may prove especially advantageous since well operators will be able to install fiber optic monitoring equipment without requiring multiple optical fiber splices at each screen joint or several other locations along a completion assembly, a task that can be quite expensive and time-consuming.

[0014] Referring to FIG. 1, illustrated is an exemplary well system 100 which can embody or otherwise employ one or more principles of the present disclosure, according to one or more embodiments. As depicted, the well system 100 includes a wellbore 102 that extends through various earth strata and has a substantially vertical section 104 that transitions into a substantially horizontal section 106. The upper portion of the vertical section 104 may have a liner or casing string 108 cemented therein, and the horizontal section 106 may extend through a hydrocarbon bearing subterranean formation 110. As illustrated, the horizontal section 106 may be arranged within or otherwise extend through an open hole section of the wellbore 102. In other embodiments, however, the horizontal section 106 of the wellbore 102 may be completed, without departing from the scope of the disclosure.

[0015] A tubing string 112 may be positioned within the wellbore 102 and extend from the surface (not shown). The tubing string 112 provides a conduit for fluids extracted from the formation 110 to travel to the surface. At its lower end, the tubing string 112 may be coupled to a completion assembly 114 generally arranged within the horizontal section 106. The completion assembly 114 serves to divide the completion interval into various production intervals adjacent the formation 110. As depicted, the completion assembly 114 may include a plurality of sand control screen assemblies 116 axially offset from each other along portions of the completion assembly 114. Each screen assembly 116 may be positioned between a pair of wellbore isolation devices or packers 118 that provides a fluid seal between the completion assembly 114 and the wellbore 102, thereby defining corresponding production intervals. In operation, the screen assemblies 116 serve the primary function of filtering particulate matter out of the production fluid stream such that particulates, sand, and/or other fines are not produced to the surface.

[0016] One or more control lines 120 (one shown) may extend from the surface within the annulus 122 defined between the inner wall of the wellbore 102 and the tubing string 112. While not shown in FIG. 1, the control line 120 may be clamped or otherwise secured to the outer surface of the tubing string 112 at various locations along its axial length . The control line 120 is a generally tubular structure capable of providing instructions, carrying power, signals and data, and transporting operating fluids (e.g., hydraulic fluid) to one or more sensors and actuators associated with the screen assemblies 116 and/or other tools or components positioned downhole. Accordingly, the control line 120 may be representative of or otherwise include one or more hydraulic lines, one or more electrical lines, and/or one or more fiber optic lines that extend from the surface external to the tubing string 112. For purposes of the present disclosure, however, the control line 120 may be generally representative of an optical cable encompassing multiple optical fibers extending from the surface. As such, the control line 120 may be configured to facilitate the monitoring of one or more fluid and/or well environment parameters.

[0017] Upon reaching the completion assembly 114, the control line 120 may be communicably coupled to a control line housing 124 that is coupled to or otherwise forms an integral part of the tubing string 112. As will be described in greater detail below, in at least one embodiment the control line housing 124 may provide a pressure barrier or container that houses a fiber optic splicing block that provides fiber optic data communication to and from the completion assembly 114. One or more hydraulic conduits 126 (one shown) may extend downhole from the control line housing 124 and through all or a portion of the completion assembly 114. In some embodiments, as illustrated and described in greater detail below, the hydraulic conduits 126 may bypass the packers 118 and extend through the interior of one or more of the screen assemblies 116.

[0018] Once the completion assembly 114 is positioned as shown within the wellbore 102, a treatment fluid containing sand, gravel, proppants or the like may be pumped down the completion assembly 114 such that the formation 110 and the several production intervals defined between adjacent packers 118 may be treated. One or more sensors (not shown) operably associated with the completion assembly 114 may be employed to provide substantially real-time data to a well operator via the control lines 120.

[0019] Such real-time data may include the effectiveness of the treatment operation, such as identifying voids during the gravel placement process to allow the operator to adjust treatment parameters such as pump rate, proppant concentration, fluid viscosity and the like to overcome deficiencies in the gravel pack. In addition, the sensors associated with the completion assembly 114 may be used to provide valuable information to the operator via the control lines 120 during the production phase of the well such as fluid temperature, pressure, velocity, flow rate, water cut, constituent composition, seismic waves (e.g., flow-induced vibrations), radioactivity and the like such that the well operator can enhance production operations.

[0020] It should be noted that even though FIG. 1 depicts the screen assemblies 116 as being arranged in an open hole portion of the wellbore 102, embodiments are contemplated herein where one or more of the screen assemblies 116 is arranged within cased portions of the wellbore 102. Also, even though FIG. 1 depicts single sand screen assemblies 116 having three screen jackets (discussed further in FIG. 2) in each production interval, it should be understood by those skilled in the art that any number of screen assemblies 116, each having any number of screen jackets, may be deployed within a production interval, without departing from the principles of the present invention. In addition, even though FIG. 1 depicts multiple production intervals separated by the packers 118, it will be understood by those skilled in the art that the completion interval may include any number of production intervals with a corresponding number of packers 118 arranged therein. In other embodiments, the packers 118 may be entirely omitted from the completion interval, without departing from the scope of the disclosure.

[0021] Further, even though FIG. 1 depicts the screen assemblies 116 as being arranged in a generally horizontal section 106 of the wellbore 102, those skilled in the art will readily recognize that the principles of the present disclosure are equally well suited for use in vertical wells, deviated wellbores, slanted wells, multilateral wells, combinations thereof, and the like. As used herein, directional terms such as above, below, upper, lower, upward, downward, left, right, uphole, downhole and the like are used in relation to the illustrative embodiments as they are depicted in the figures, the upward direction being toward the top of the corresponding figure and the downward direction being toward the bottom of the corresponding figure, the uphole direction being toward the surface of the well and the downhole direction being toward the toe of the well.

[0022] Referring now to FIG. 2, with continued reference to FIG. 1, illustrated is a partial cut-away view of one of the sand control screen assemblies 116 of FIG. 1, according to one or more embodiments of the present disclosure. Like numerals used in both FIGS. 1 and 2 refer to like elements that will not be described again in detail. The sand control screen assembly 116 may include a base pipe 202 that defines a plurality of openings 204 that allow the flow of production fluids into the base pipe 202. As will be appreciated, the exact number, size, and shape of the openings 204 are not critical to the present disclosure, so long as sufficient area is provided for fluid production and the integrity of the base pipe 202 is maintained.

[0023] Positioned around the base pipe 202 may be a fluid-porous, particulate restricting filter medium, such as a plurality of layers of a wire mesh that form a screen 206. A plurality of longitudinal rods or ribs 208 may extend longitudinally between the screen 206 and the outer surface of the base pipe 202 in order to maintain the integrity of the screen 206 and otherwise support the screen 206 during operation. The screen 206 may exhibit a predetermined filter gauge designed to allow fluid flow therethrough but prevent the flow of particulate matter or sand of a predetermined size from passing therethrough. As a result, particulate matter or sand of a particular size or greater will be generally prevented from flowing through the screen 206 and produced to the surface through the base pipe 202. [0024] The screen 206 may be made from of a plurality of layers of a wire mesh that are diffusion bonded or sintered together to form a fluid porous wire mesh screen . In other embodiments, however, the screen 206 may have multiple layers of a weave mesh wire material having a uniform pore structure and a controlled pore size that is determined based upon the properties of the formation 110 (FIG. 1). For example, suitable weave mesh screens may include, but are not limited to, a plain Dutch weave, a twilled Dutch weave, a reverse Dutch weave, combinations thereof, or the like. In yet other embodiments, the screen 206 may include a single layer of wire mesh, multiple layers of wire mesh that are not bonded together, a single layer of wire wrap, multiple layers of wire wrap or the like, that may or may not operate with a drainage layer. Those skilled in the art will readily recognize that several other mesh designs are equally suitable, without departing from the scope of the disclosure. In at least one embodiment, the screen 206 may be an expandable-type screen.

[0025] The screen assembly 116 may further include an outer shroud

210 positioned around the screen 206 and defining a plurality of apertures 212 that allow the flow of production fluids therethrough . As with the openings 204 in the base pipe 202, the exact number, size and shape of the apertures 212 in the shroud 210 are not critical to the present disclosure, so long as sufficient area is provided for fluid production and the integrity of the outer shroud 210 is maintained. Various sections of the screen 206 and the outer shroud 210 may be manufactured together as a unit, and may be characterized as or otherwise referred to herein as a "screen jacket." Accordingly, use of the term "screen jacket" may refer to a combination of one or more screens 206 and one or more outer shrouds 210, but may equally refer to the outer shroud 210 independent of the screen 206. One or several screen jackets may be included in a single screen assembly 116 and may be placed over each joint of the base pipe 202 and secured thereto by welding or other suitable techniques known in the art.

[0026] Even though the sand control screen assembly 116 has been depicted and described as having a wire mesh filter medium (e.g., the screen 206), it should be understood by those skilled in the art that the screen assemblies of the present disclosure may use any type of filter media including, but not limited to, a single layer wire wrapped filter medium, a multi-layer wire wrapped filter medium, a pre-packed filter medium or the like that may include or exclude an outer shroud, without departing from the scope of the present disclosure.

[0027] The sand control screen assembly 116 may further include one or more hydraulic conduits 126 (six shown) arranged longitudinally within the screen 206 and otherwise interposing the screen 206 and the outer surface of the base pipe 202. The hydraulic conduits 126 may be continuous tubular structures extending along {i.e., within) all or a portion of one or more sand screen assemblies 116. As will be discussed below, some of the hydraulic conduits 126 may be made of one or more tubular lengths coupled together so as to provide a longer overall length. In some embodiments, as illustrated, several individual hydraulic conduits 126 may be arranged about the circumference of the base pipe 202. In other embodiments, however, the hydraulic conduits 126 may be located at a single location about the circumference of the base pipe 202, without departing from the scope of the disclosure.

[0028] The hydraulic conduits 126 may be made from a variety of materials. In some embodiments, for example, one or more of the hydraulic conduits 126 may be made of stainless steel, such as 304L stainless steel, 316L stainless steel, 420 stainless steel, or 410 stainless steel. In other embodiments, however, one or more of the hydraulic conduits 126 may be made of other materials such as, but not limited to, 13 chrome, Incoloy 825, AISI 4041 steel, or similar alloys. One or more of the hydraulic conduits 126 may be cylindrical in shape, as depicted in FIG. 2. In other embodiments, however, one or more of the hydraulic conduits 126 may exhibit other shapes, such as ovoid, elliptical, or polygonal (e.g., triangular, square, rectangular, etc.), without departing from the scope of the disclosure. In some embodiments, one or more of the hydraulic conduits 126 may be sized at about ¹ Λ inch in diameter. In other embodiments, however, the hydraulic conduits 126 may be sized greater or less than ¹ Λ inch in diameter, without departing from the scope of the disclosure.

[0029] Referring now to FIG. 3, with continued reference to FIGS. 1 and 2, illustrated is a schematic diagram of an exemplary completion assembly 300, according to one or more embodiments. The completion assembly 300 may be substantially similar to the completion assembly 114 of FIG. 1 and therefore may be best understood with reference thereto, where like numerals represent like elements not described again in detail. As depicted, the completion assembly 300 may include a plurality of sand control screen assemblies 116 axially offset from each other along portions of the completion assembly 300. Each screen assembly 116 may include one or more screen jackets, as generally described above. Moreover, each screen assembly 116 may be positioned between a pair of wellbore isolation devices or packers 118 that provides a fluid seal between the completion assembly 114 and the wellbore 102 (FIG. 1), thereby defining corresponding production intervals, shown as a first interval 302a, a second interval 302b, and a third interval 302c.

[0030] Each screen assembly 116 may further include one or more flow control devices 304. The flow control devices 304 may be any type of flow- regulating device known to those skilled in the art. For example, the flow control devices 304 may include, but are not limited to, an inflow control device, an autonomous inflow control device, a valve (e.g., expandable-type, expansion- type, etc.), a sleeve, a sleeve valve, a sliding sleeve, a flow restrictor, a check valve (operable in either direction, in series or in parallel with other check valves, etc.), combinations thereof, or the like. In operation, the screen assemblies 116 serve to filter particulate matter out of the production fluid stream, and the flow control devices 304 prevent or otherwise restrict fluid flow into the interior of the tubing string 112 (FIG. 1) .

[0031] The completion assembly 300 may further include, or have associated therewith, a control line housing 306 similar to the control line housing 124 of FIG. 1. The control line housing 306 may be configured to receive the control line 120 that extends from the surface and provide a pressure barrier or container that houses a fiber optic splicing block 308. The fiber optic splicing block 308 may have one or more optical fibers or cables 310 (shown as fiber optic cables 310a, 310b, 310c, and 310d) spliced thereto that provide fiber optic data communication to and from various portions of the completion assembly 300.

[0032] One or more hydraulic conduits 126 (shown as hydraulic conduits 126a, 126b, 126c, and 126d) may extend from the control line housing 306 longitudinally into the completion assembly 300. More particularly, the first hydraulic conduit 126a may extend from the control line housing 306 and terminate in the first interval 302a, the second hydraulic conduit 126b may extend from the control line housing 306 and terminate in the second interval 302b, and the third hydraulic conduit 126c may extend from the control line housing 306 and terminate in the third interval 302c. Each hydraulic conduit 126a-c passes through at least one packer 118 and possibly through multiple screen jackets in order to reach its desired location within the corresponding intervals 302a-c. Moreover, as described with reference to FIG. 2 above, each of the hydraulic conduits 126a-d may be arranged longitudinally within a screen (e.g., screen 206 of FIG. 2) and otherwise interposing the screen and the outer surface of a base pipe (e.g., base pipe 202 of FIG. 2) . Accordingly, the hydraulic conduits 126a-d may be continuous tubular structures extending along (/ ^' .e., within) all or a portion of the screen assembly 300.

[0033] In one or more embodiments, the first, second, and third hydraulic conduits 126a-c may be used to help measure or otherwise monitor one or more wellbore parameters. More particularly, the first, second, and third hydraulic conduits 126a-c may be configured to convey and sense real-time pressures within the first, second, and third intervals 302a-c, respectively. To accomplish this, each hydraulic conduit 126a-c may be communicably coupled to a pressure sensor or gauge 312 (shown as gauges 312a, 312b, and 312c) arranged within the control line housing 306. The distal end of each hydraulic conduit 126a-c may be left open or otherwise exposed to the environment in each interval 302a-c, thereby allowing the hydraulic conduits 126a-c to provide a fluid pathway for fluid pressures to be conveyed to corresponding pressure gauges 312a-c. Accordingly, the first pressure gauge 312a may be configured to detect fluid pressure in the first interval 302a as propagated through the first hydraulic conduit 126a, the second pressure gauge 312b may be configured to detect fluid pressure in the second interval 302b as propagated through the second hydraulic conduit 126b, and the third pressure gauge 312c may be configured to detect fluid pressure in the third interval 302c as propagated through the third hydraulic conduit 126c.

[0034] In some embodiments, the pressure gauges 312a-c may be any type of pressure gauge known to those skilled in the art. The optical fibers or cables 310a-c extend from the corresponding pressure gauges 312a-c and are spliced into the fiber optic splicing block 308 such that the detected or measured pressures in each interval 302a-c may be communicated to the surface in realtime via the control line 120. In other embodiments, however, the pressure gauges 312a-c may be a type of electrical pressure gauge known to those skilled in the art, and the optical cables 310a-c may be electrical or electro-optical lines spliced into the splicing block 308 or otherwise extended to the surface such that the detected or measured pressures in each interval 302a-c may be communicated to the surface.

[0035] As will be appreciated, having the hydraulic conduits 126a-c extend into each interval 302a-c eliminates the need to individually place the pressure gauges 312a-c in each screen assembly 116 to measure pressures in each interval 302a-c. Rather, the fluid pressure present in each interval 302a-c is able to communicate up each corresponding hydraulic conduit 126a-c to the respective pressure gauge 312a-c arranged in the control line housing 306. Such a feature will prove advantageous during the construction of the completion assembly 300, which would otherwise require multiple optical fiber splices at each screen joint, packer 118, etc., which can be a fairly expensive and time-consuming process. Moreover, as will be appreciated by those skilled in the art, fiber optic splice housings may also have a large outer diameter which may pose a significant disadvantage in a size-constrained environment. Multiple fiber optic splices may also introduce a larger failure probability when compared with a pre-manufactured cable or pristine optical fiber.

[0036] The fourth hydraulic conduit 126d may provide a means for measuring or otherwise monitoring other wellbore parameters, such as Distributed Temperature Sensing (DTS) and/or Distributed Acoustic Sensing (DAS) within each interval 302a-c. More particularly, the fourth hydraulic conduit 126 may have the fourth fiber optic cable 310d disposed therein and extending substantially its entire length and thereby encompassing each of the first, second, and third intervals 302a-c. The fiber optic cable 310d may have multiple optical fibers where the fibers may be single-mode and/or multi-mode optical fibers.

[0037] In some embodiments, the fiber optic cable 310d may be hydraulically inserted into the fourth hydraulic conduit 126d. To accomplish this, a pump 314 may be fluidly coupled to the fourth hydraulic conduit 126d and configured to convey a fluid 316 into the fourth hydraulic conduit 126d while the fiber optic cable 310d is simultaneously being fed therein. A distributed drag force generated by the fluid 316 acts on and impels the fiber optic cable 310d to the distal end of the fourth hydraulic conduit 126d. A check valve 318 may be arranged at the distal end of the fourth hydraulic conduit 126d and configured to allow the fluid 316 to exit the distal end of the fourth conduit 216d but prevent the pumped fiber optic cable 310d from advancing any further and escaping. The check valve 318 may also maintain a pressure seal at the end of the fourth conduit 216d during operation .

[0038] In other embodiments, the fourth hydraulic conduit 126d may be a dual ended conduit including a deployment conduit 320a and a return conduit 320b. In such an embodiment, the check valve 318 may be replaced with a turnaround sub 322 that interposes the deployment and return conduits 320a, b and otherwise provides a fluid connection between the two conduits 320a, b. The pump 314 conveys the fluid 316 into the deployment conduit 320a while the fiber optic cable 310d is simultaneously fed therein . At the turnaround sub 322, the fluid 316 makes a U-turn and returns to the pump 314 via the return conduit 320b and a return line 324 fluidly coupled to the pump 314. Again, the fluid 316 imparts a distributed drag force on the fiber optic cable 310d that tends to impel and advance the fiber optic cable 310d to the distal end of the deployment conduit 320a. The turnaround sub 322 receives the fiber optic cable 310d and generally stops its axial progress.

[0039] Once the fiber optic cable 310d is extended within the fourth hydraulic conduit 126d (using either method described above), the fiber optic cable 310d may be secured within the fourth hydraulic conduit 126d using, for example a Swagelok-type coupling or the like. In some embodiments, the fiber optic cable 310d may be pre-manufactured with a fiber optic connector (not shown) at its end. The fiber optic connector may include a pressure barrier to mitigate fluid communication in case the fiber optic cable 310d is breached. The fiber optic cable 310d may then be spliced into the fiber optic splicing block 308 such that the detected or measured temperatures or acoustic signals along the entire completion assembly 300 and in each interval 302a-c may be communicated to the surface via the optical fibers in the control line 120. Accordingly, in exemplary operation, the fourth fiber optic cable 310 and the fourth hydraulic conduit 126d and may provide distributed temperature sensing (DTS) and/or distributed acoustic sensing (DAS) along the length of the completion assembly 300.

[0040] The fiber optic splicing block 308 may be configured to receive the fiber optic cables 310a-d and channel them into a single optical cable {i.e., the control line 120) consisting of several optical fibers. The fiber optic splicing block 308 may further include suitable pressure barriers used to prevent fluid communication in case any of the components located downhole therefrom is mechanically breached. In some embodiments, as mentioned above, the control line 120 may extend to the surface. In other embodiments, however, the control line 120 may extend to another completion assembly arranged uphole from the completion assembly 300 of FIG. 3. In such embodiments, the control line 120 may be communicably coupled to the other completion assembly using, for example, a down-hole fiber optic wet-connect.

[0041] Referring now to FIG. 4, with continued reference to FIGS. 2 and 3, illustrated is a cross-sectional view of adjacent sand control screen assemblies, according to one or more embodiments. More particularly, illustrated is a first sand control screen assembly 402a arranged axially uphole {i.e., to the left in FIG. 4) from a second sand control screen assembly 402b. The first and second screen assemblies may 402a, b be similar in some respects to the screen assemblies 116 of FIGS. 2 and 3, and therefore may be best understood with reference thereto.

[0042] The screen assemblies 402a, b may be arranged about a base pipe 404, which may include an elongate section of pipe, or may be split up into two or more portions, such as base pipe portions 404a and 404b (collectively "base pipe 404"). For instance, as illustrated, the first screen assembly 402a may be generally arranged about a first base pipe 404a, and the second screen assembly 402b may be generally arranged about a second base pipe 404b. The first and second base pipes 404a, b may be coupled together using a base pipe coupling 406. In some embodiments, the base pipe coupling 406 is a threaded ring configured to receive corresponding threaded ends of each of the first and second base pipes 404a, b in order to couple the base pipes 404a, b together. In other embodiments, however, the base pipe coupling 406 may be a threaded box end coupling for either of the first or second base pipes 404a, b configured to receive a correspondingly threaded pin end of the other of the first or second base pipes 404a, b.

[0043] The base pipe 404 may further define one or more perforations or openings 408 configured to provide fluid communication between the interior 410 of the base pipe 404 and the formation 110. Each screen assembly 402a, b may further include a screen jacket 412 arranged about the exterior of the base pipe 404. One or both of the screen jackets 412 may include a screen filter (e.g., the screen 206 of FIG. 2) and an outer shroud (e.g., shroud 210 of FIG. 2). In other embodiments, however, one or both of the screen jackets may include only the screen filter or only the outer shroud, without departing from the scope of the disclosure. In operation, the screen jackets 412 may serve as a filter medium designed to allow fluids derived from the surrounding formation 110 to flow therethrough but prevent the influx of particulate matter of a predetermined size.

[0044] Each screen jacket 412 may be secured to the base pipe 404 using end rings 414 arranged at each end of the screen jacket 412. The end rings 414 provide a mechanical interface between the base pipe 404 and the opposing ends of the screen jackets 412. In some embodiments, one or both of the end rings 414 may be shrink rings. Each end ring 414 may be formed from a metal such as 13 chrome, 304L stainless steel, 316L stainless steel, 420 stainless steel, 410 stainless steel, Incoloy 825, or similar alloys. Moreover, each end ring 414 may be coupled or otherwise attached to the outer surface of base pipe 404 by being welded, brazed, threaded, combinations thereof, or the like. In other embodiments, however, one or more of the end rings 414 may be an integral part of the corresponding screen jacket 412, and not a separate component thereof.

[0045] As illustrated, a hydraulic conduit 416 may extend through at least a portion of each of the first and second screen assemblies 402a, b. More particularly, the hydraulic conduit 416 may extend through the first and second screen assemblies 402a, b between the screen jacket 412 and the outer surface of the base pipe 404. The hydraulic conduit 416 may be similar to the hydraulic conduits 126 of FIGS. 2 and 3 and therefore will not be described again in detail. Opposing ends of the hydraulic conduit 416 may be coupled together at one or more conduit couplings 418. The conduit coupling 418 provides a sealed interface that fluidly connects the opposing ends of the hydraulic conduit 416 such that the overall length of the hydraulic conduit 416 may be extended. In some embodiments, the hydraulic conduit 416 may be clamped to the outer surface of the base pipe 404 between the screen assemblies 402a, b. For instance, one or more cross coupling protectors 420 may be used to protect the hydraulic conduit 416 as it crosses over the base pipe coupling 406.

[0046] Each end ring 414 may define a hole 422 configured to receive and otherwise secure the hydraulic conduit 416 therein as the hydraulic conduit 416 passes into and out of each screen assembly 402a, b. As described below, the hydraulic conduit 416 may be secured within the hole 422 using one or more mechanical fasteners (not shown in FIG. 4) configured to clamp and/or substantially seal an interface between the hole 422 and the hydraulic conduit 416. In other embodiments, however, the hydraulic conduit 416 may be arranged in the hole 422 with an interference fit such that particulate matter or sand of a predetermined size and greater is prevented from passing into the screen assemblies 402a, b via the hole 422.

[0047] Referring now to FIGS 5A-5C, with continued reference to FIG. 4, illustrated are cross-sectional views of a portion of a sand control screen assembly 500, according to one or more embodiments of the present disclosure. The sand control screen assembly 500 may be similar in some respects to the screen assemblies 116 and 402a, b of FIGS. 2 and 4, respectively, and therefore may be best understood with reference thereto, where like numerals represent like components not described again in detail. In FIG. 5A, as illustrated, the hydraulic conduit 416 extends into the screen assembly 500 via the hole 422 defined in the end ring 414. In the illustrated embodiment, the screen assembly 500 includes a screen 206 and the hydraulic conduit 416 extends within the screen assembly 500 generally interposing the screen 206 and the outer surface of the base pipe 404.

[0048] The screen assembly 500 may further include a mechanical fastener 502 configured to generally secure the hydraulic conduit 416 within the hole 422. As illustrated, the mechanical fastener 502 may be a Swagelok-type fastener. More particularly, the mechanical fastener 502 may include a threaded nut 504 configured to threadably engage corresponding threads 506 defined on the inner surface of the hole 422. The nut 504 may define a central channel 505 configured to longitudinally receive the hydraulic conduit 416 therein. The mechanical fastener 502 may further include a pair of compression ferrule rings 508. 508 As the nut 504 is threadably advanced into the hole 422, the rings 508 are compressed against their opposing beveled surfaces and simultaneously forced into sealing engagement with the outer surface of the hydraulic conduit 416 and the inner surface of the hole 422. As a result, the mechanical fastener 502 may create a substantially sealed interface at the end ring 414 such that particulate matter or sand is prevented from entering into the screen assembly 500 through the hole 422. Accordingly, the mechanical fastener 502 may seal and mechanically fasten the hydraulic conduit 416 within the hole 422.

[0049] Referring to FIG. 5B, the screen assembly 500 may include the screen 206 and an outer shroud 210 arranged about the screen 206 {i.e., a screen jacket). As described above, the openings 212 in the outer shroud 210 provide fluid communication between the formation 110 and the interior of the screen assembly 500. In at least one embodiment, one or both of the screen 206 and the outer shroud 210 may be welded 510 to the end ring 414.

[0050] The mechanical fastener 502 depicted in FIG. 5B may be in the form of an annular wedge. More particularly, the mechanical fastener 502 may include a central conduit 514 configured to longitudinally receive the hydraulic conduit 416 therein . One end of the mechanical fastener 502 may be tapered and otherwise define a tapered surface 516. The opposing end of the mechanical fastener 502 may define a jarring surface 518 and an annular protrusion 520. To install the mechanical fastener 502, and thereby secure the hydraulic conduit 416 within the hole 422, the jarring surface 518 may be struck with a hammer or other blunt object until the annular protrusion 520 is forced past an annular shoulder 522 defined by the end ring 414 within the hole 422.

[0051] Continued movement of the mechanical fastener 502 in the same direction may force the tapered surface 516 into contact with a corresponding tapered surface 524 defined by the hole 422. Mutual engagement between the tapered surfaces 516 and 524 may force the mechanical fastener 502 to clamp down on the hydraulic conduit 416 such that the hydraulic conduit 416 is secured within the end ring 414, but may also substantially seal the interface such that particulate matter or sand is prevented from entering into the screen assembly 500 through the hole 422.

[0052] In some embodiments, the mechanical fastener 502 may be a collet and the annular protrusion 520 may be defined on axially extending fingers that are able to flex into the hole 422 past the shoulder 522 and thereafter snap into place. In other embodiments, the shoulder 522 may be omitted and the mechanical fastener 502 may instead be welded into place once arranged at a desired location within the hole 422.

[0053] Referring to FIG. 5C, the hydraulic conduit 416 extends into the screen assembly 500 via the hole 422 defined in the end ring 414 and generally interposing the screen 206 and the outer surface of the base pipe 404. In the illustrated embodiment, the hydraulic conduit 416 may be secured to the end ring 414 without the aid of a mechanical fastener (e.g., mechanical fastener 502 of FIGS. 5A and 5B) . Rather, the end ring 414 may be a shrink ring configured to provide an interference fit for the hydraulic conduit 416 within the hole 422. In some embodiments, the end ring 414 may be heated so that the size of the hole 422 increases and allows the hydraulic conduit 416 to be freely extended therein. Upon cooling, the size of the hole 422 will decrease and the hole 422 may sealingly engage the outer surface of the hydraulic conduit 416 and thereby securing the conduit.

[0054] In other embodiments, however, the hole 422 may be sized such that the hydraulic conduit 416 may be extended therethrough without an interference fit. Rather, any remaining gap defined between the inner surface of the hole 422 and the outer surface of the hydraulic conduit 416 may be designed to be gauged less than or equal to the gauge of the screen 206. As a result, particulate matter or sand of a predetermined size or greater will nonetheless be prevented from entering the screen assembly 500 via the hole 422.
