It is well known in the subterranean well drilling and completion art that relatively fine particulate materials may be produced during the production of hydrocarbons from a well that traverses an unconsolidated or loosely consolidated formation. Numerous problems may occur as a result of the production of such particulate. For example, the particulate causes abrasive wear to components within the well, such as flow control devices, safety equipment, tubing and the like. In addition, the particulate may partially or fully clog the well, creating the need for an expensive workover. Also, if the particulate matter is produced to the surface, it must be removed from the hydrocarbon fluids using surface processing equipment.
One method for preventing the production of such particulate material is to gravel pack the well adjacent to the unconsolidated or loosely consolidated production interval. In a typical gravel pack completion, sand control screen assemblies are lowered into the wellbore as part of a completion string to a position proximate the desired production interval. A fluid slurry including a liquid carrier and a relatively coarse particulate material, such as sand, gravel or proppants which are typically sized and graded (e.g., which are typically referred to herein as gravel), is then pumped down the work string and into the well annulus formed between the sand control screen assemblies and the perforated well casing or open hole production zone. The liquid carrier either flows into the formation or returns to the surface by flowing through a wash pipe or both. In either case, the gravel is deposited around the sand control screen assemblies to form the gravel pack, which is highly permeable to the flow of hydrocarbon fluids but blocks the flow of the fine particulate materials carried in the hydrocarbon fluids. As such, gravel packs can successfully prevent the problems associated with the production of these particulate materials from the formation.
It is also well known in the subterranean well drilling and completion art that it is desirable to install smart well components that enable the management of downhole equipment and production fluids. For example, these smart well components may include one or more sensing devices such as temperature sensors, pressure sensors, flow rate sensors, fluid composition measurement devices or the like, as well as 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.
It has been found, however, that the control lines installed radially outside of the sand control screen assemblies, smart well components, and/or centralizers are susceptible to damage during installation and operation thereof in the wellbore.
Reference is now made to the following descriptions taken in conjunction with the accompanying drawings, in which:
In the drawings and descriptions that follow, like parts are typically marked throughout the specification and drawings with the same reference numerals, respectively. The drawn figures are not necessarily, but may be, to scale. Certain features of the disclosure may be shown exaggerated in scale or in somewhat schematic form and some details of certain elements may not be shown in the interest of clarity and conciseness. The present disclosure may be implemented in embodiments of different forms. Specific embodiments are described in detail and are shown in the drawings, with the understanding that the present disclosure is to be considered an exemplification of the principles of the disclosure, and is not intended to limit the disclosure to that illustrated and described herein. It is to be fully recognized that the different teachings of the embodiments discussed herein may be employed separately or in any suitable combination to produce desired results. Moreover, all statements herein reciting principles and aspects of the disclosure, as well as specific examples thereof, are intended to encompass equivalents thereof. Additionally, the term, “or,” as used herein, refers to a non-exclusive or, unless otherwise indicated.
Unless otherwise specified, use of the terms “connect,” “engage,” “couple,” “attach,” or any other like 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.
Unless otherwise specified, use of the terms “up,” “upper,” “upward,” “uphole,” “upstream,” or other like terms shall be construed as generally away from the bottom, terminal end of a well, regardless of the wellbore orientation; likewise, use of the terms “down,” “lower,” “downward,” “downhole,” or other like terms shall be construed as generally toward the bottom, terminal end of a well, regardless of the wellbore orientation. Use of any one or more of the foregoing terms shall not be construed as denoting positions along a perfectly vertical or horizontal axis. Unless otherwise specified, use of the term “subterranean formation” shall be construed as encompassing both areas below exposed earth and areas below earth covered by water, such as ocean or fresh water.
The present disclosure has acknowledged that adding a Line Control System (LCS) to downhole tools, such as smart well system, sand control system, or other downhole system, presents an issue with control line guides and control line retention. For example, the lines (e.g., hydraulic lines, electrical lines, fiber optic bundles or the like and combination thereof) must be guided through any features of the downhole tools (e.g., including centralizers, housings, valves etc.) such that the lines are not damaged during installation and/or deployment. Based at least in part on this acknowledgment, the present disclosure has realized that a bypass channel may be included within the downhole tool that the lines are traversing, which would allow the lines to be protected by the housing the bypass channel is located. In one or more embodiments, the bypass channel is open at a radial exterior surface thereof, and thus a radial retention mechanism, such as a clip or other similar feature, may be used to radially retain the lines within the open bypass channel.
The present disclosure has recognized that the bypass channel is particularly useful in a centralizer, as might be used with a sand control system. In such an embodiment, the bypass channel could be milled into the radial exterior surface of the centralizer, or alternatively cast within the radial exterior surface of the centralizer (e.g., among other methods), thereby allowing the lines to nest within the bypass channel, and thus be protected during installation and/or deployment. Similarly, the centralizer could employ a radial retention mechanism, as discussed above, to retain the lines within the open bypass channel of the centralizer. While a certain type of centralizer has been discussed herein, any type of centralizer is within the scope of the disclosure. For example, the centralizers could be spiral in nature (e.g., able to spin for open hole applications) or a fixed blade in nature (e.g., for cased hold applications). Furthermore, in certain embodiments the centralizer is a weld on centralizer. However, in other embodiments the centralizer could be a bolt on centralizer or clam shell type centralizer. In at least one embodiment, the guide/retention types may be timed to the connections to keep the path of the LCS conduits as straight as possible.
The present disclosure has further recognized that the bypass channel is particularly useful in a flow control device, such as an inflow control device (ICD) or autonomous inflow control device (AICD) of a smart well system. In such an embodiment, the bypass channel could be milled into the radial exterior surface of the flow control device, or alternatively cast within the radial exterior surface of the flow control device (e.g., among other methods), thereby allowing the lines to nest within the bypass channel, and thus be protected during installation and/or deployment. Similarly, the flow control device could employ a radial retention mechanism, as discussed above, to retain the lines within the open bypass channel of the flow control device.
The present disclosure has even further recognized that the bypass channel is particularly useful in a valve of a screen assembly, screen clamp, end ring, etc., among other locations in other downhole devices. Ultimately, the bypass channel can be added to centralizers, housings, valves, screens, screen shrouds, shunt screens, etc. to effectively guide and retain LCS conduits. Since the bypass channel, at least in certain embodiments, is an open bypass channel, the lines and/or conduits may be added on at the rig floor. Furthermore, the timed connection and/or timed component placement (e.g., within a housing) helps to ensure the alignment of any guide features and radial retention mechanisms.

One or more control lines 40 extend from the surface within annulus 42 as pass through the completion string 22 and/or sand control screen assemblies 24, 32 to provide instructions, carry power, signals and data, and transport operating fluid, such as hydraulic fluid, to sensors, actuators and the like associated with sand control screen assemblies 24, 32 and other tools or components positioned downhole.
In one example, once completion string 22 is positioned as shown within wellbore 12, a treatment fluid containing sand, gravel, proppants or the like may be pumped down completion string 22 such that formations 14, 16 and production intervals 26, 34 may be treated. Sensors operably associated with the completion string 22 may be used to provide substantially real time data to the operator via control line 40 on 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, such sensors may be used to provide valuable information to the operator via control line 40 during the production phase of the well such as fluid temperature, pressure, velocity, constituent composition and the like such that the operator can enhance the production operations.

As can be seen in certain of the FIGS., in certain embodiments a wall thickness (t) of the uphole centralizer 210 may the thicker near the bypass channel 212 (e.g., t1) than opposite the bypass channel 212 (e.g., t2). This thicker region allows the bypass channel 212 to be formed in the uphole centralizer 210 while assuring that the one or more control lines 280 may reside therein without extending radially outside an outermost feature of the uphole centralizer 210. Accordingly, in at least one embodiment, the ID of the centralizer 210 and the OD of the centralizer 210 is eccentric to create the thicker region.

Those skilled in the art understand that the size and position of the axial retention mechanism 410A may be adjusted on a case by case basis to radially, frictionally, and axially fix different sizes and shapes of control lines. For example, the size and shape of the one or more protrusions 420A or radial retention mechanism 214 could be modified, and switched out, on a case by case basis to radially, frictionally, and axially fix different sizes and shapes of control lines.
