TRANSPORTED BY PIPE
FIELD OF THE INVENTION
This disclosure generally relates to the equipment used and the operations carried out in conjunction with underground wells and, in an example described below, more particularly provides a pipeline transported intelligent multi-zone integrated well completion.
BACKGROUND OF THE INVENTION
When it is to be produced from (or injected into) multiple zones from an underground well, it can be difficult to determine how fluids communicate between a land formation and a pipeline in the well. This can be particularly difficult where fluids produced from the multiple zones mix in the pipeline chain, or where the same fluid is injected from the well into the multiple zones.
Therefore, it will be appreciated that improvements are continually needed in the field of construction and operation of well completion systems.
BRIEF DESCRIPTION OF THE INVENTION ^ /// /
IKOUiTAiAL
<img file="MX355148B_D0010.tif" />
In this disclosure, systems and methods are provided that bring improvements to the subject of construction and operation of well completion systems. An example is described below in which a variable flow restriction device is configured to receive fluid flowing through a well filter. Another example is described below in which an optical waveguide is positioned external to a pipe chain, and one or more pressure sensors detect internal and / or external pressure to the pipe chain.
These and other features, advantages and benefits will become apparent to someone skilled in the art with careful consideration of the detailed description of the representative disclosure modalities below and the accompanying drawings, in which similar elements are indicated in the different figures using the same reference numbers.
BRIEF DESCRIPTION OF THE DRAWINGS

Figures 2A-2C are representative cross-sectional views of successive longitudinal sections of a pipe chain that can be used in the well completion method and system of Figure 1, and that can incorporate the principles of this disclosure.
Figure 3 is a representative cross-sectional view of a section of the pipeline chain, with fluid flowing from a soil formation into the pipeline chain.

DETAILED DESCRIPTION OF THE INVENTION Figure 1 representatively illustrates a well completion system 10 and associated method that may incorporate the principles of this disclosure. However, it should be clearly understood that the system 10 and the method are iVl. X / 'ixXK-r ·. 0 only an example of an application of 1 ο ^^ '^ £ ^ Η ^ α01000 ^ 00 / this disclosure in practice, and that a wide variety of other examples are possible. Therefore, the scope of this disclosure is not entirely limited to the details of the system 10 and method described in this document and / or depicted in the drawings.
In the example in Figure 1, a pipe chain 12 has been installed in a well 14 lined with liner 16 and cement 18. In other examples, pipe chain 12 could be installed at least partially in an uncoated portion or open hole well 14. The pipe chain can be suspended from a pipe hanger (not shown) on or near the surface of the ground (eg, on a surface or subsea wellhead).
Pipe line 12 includes multiple sets 20 of termination equipment. In some examples, all sets 20 of the termination kit can be transported into the well at the same time in the pipeline
12. An etch 22 can be placed around the well 24 filters included in the termination kit on a single trip into the well 14, using a multi-zone gravel packing system per pipeline.
For example, a system and technique that can be used to pack gravel around multiple sets of the

ENHANCED SINGLE TRIP MULTI-ZONE ™, or ESTMZ ™. However, other systems and techniques can be used without departing from the principles of this disclosure.
The shutters 26 in the pipeline 12 are used to isolate multiple zones of the earth formation 28 from each other in the well 14. The shutters 26 followed the ring 30 that is formed radially between the pipeline 12 and the well 14 Zones 28 may be different sections of the same land formation, but this is not necessary according to the scope of this disclosure.
Also included in each set of termination equipment 20 is a flow control device 32 and a hydraulic control device 34 that control the hydraulic actuation of the flow control device.
A suitable flow control device, which can variably restrict flow into and out of pipeline 12, is the IV-ICV ™ infinitely variable range control valve available from Halliburton Energy Services, Inc.

Services.
In each set of termination equipment 20, a pressure sensor 36 is included to detect the internal and / or external pressure to the pipeline 12. The pressure sensor 36 could be provided as part of the hydraulic control device 34 (such as, part of the SCRAMS ™ device), or a separate pressure sensor can be used. If a separate pressure sensor is used, a suitable sensor is the ROC ™ pressure sensor sold by Halliburton Energy
Services, Inc.
Other types of sensors can be used in addition to, or instead of, the pressure sensor 36. For example, the sensor could also, or alternatively, include a flow sensor, a water cut sensor, or fluid composition sensor, or any other type of sensors.
The shutters 26 are preferably fixed by applying internal pressure. The shutters 26 are fixed after the pipeline 12 has landed (eg, at a wellhead at or near the surface of the ground).
Preferably, no disconnect submersibles or expansion joints are required to space the pipeline 12 relative to the wellhead before attaching the plugs

A gravel packing work chain and service tool (not shown) that are used to direct the flow of a fracturing slurry and / or gravel packing into the well are installed after the plugs 26 are attached. After After the gravel packing operation is completed, the gravel packing work chain and service tool is retrieved. It can then be produced from the well through the pipeline 12.
Alternatively, or in addition, a production line 38 (such as a flexible pipe chain, etc.) can be lowered into the well 14 and nailed to the pipe chain 12, if desired. The production line 38 in this example includes seals 40 to hermetically fit a seal hole 42 into one of the uppermost of the seals 26.
Production line 38 may include an electric submersible pump 44. In other examples, pump 44 could be transported by cable or wire line, in which case pipeline 12 could be used to flow fluid 52 into the surface of the earth above the pump.

However, the use of the pump 4 4 not less initially. Pump 44 can only be installed after partial well depletion.
In system 10, as depicted in Figure 1, lines 50 are carried externally on pipe chain 12.
Preferably lines 50 include one or more electrical, hydraulic, and optical lines (eg, at least one optical waveguide, such as, an optical fiber, an optical tape, etc.). However, in other examples, all or part of lines 50 could be positioned internal to pipeline 12, or on a wall of the pipeline. The scope of this disclosure is not limited to any particular location on lines 50.
Preferably, the optical waveguide (s) is (are) external to the pipeline 12 (for example, between the filters in well 24 and well 14), such that the properties of the fluid 52 flowing between the zones 28 and the interior of the pipe chain 12 can be detected radially by means of the optical waveguide (s). In other examples, the optical waveguide could be positioned on a wall of liner 16, external to the liner, on cement 18, etc.
Preferably, the optical waveguide is capable of detecting the temperature and / or pressure of the fluid 52. By

Rayleigh on the optical waveguide as an indication of the temperature along the waveguide. For pressure detection, the optical waveguide could be equipped with Bragg fiber grids and / or Brillouin backscatter on the optical waveguide could be detected as an indication of deformation (resulting from pressure) along of the optical waveguide. The optical waveguide could be used to detect the flow rate or water cut of the fluid 52. However, the scope of this disclosure is not limited to any particular technique for detecting any particular property of the fluid 52.
Also included in the pipeline example in Figure 1, a safety valve 46 and an isolation valve 38. Safety valve 46 is used to prevent unintended fluid flow 52 out of the well (eg. ., in the event of an emergency, burst, etc.), and isolation valve 48 is used to prevent zones 28 from being exposed to potentially harmful fluids and pressures above at times during the termination process.

Safety valve 46 can be operated iMafeiiiitLZc one or more control lines 84 (such as, í · .g'l'éetrreaB<sup>1</sup> and / or hydraulic), or the safety valve can be operated using one or more of lines 50. Isolation valve 48 can be operated using one or more of lines 50.
Fluid 52 is depicted in Figure 1 as flowing from zones 28 into pipeline chain 12, as in a production operation. However, the principles of this disclosure also apply to situations (such as acidification, fracturing, other stimulation operations, compliance or other injection operations, etc.), where fluid 52 is injected from the pipeline 12 inside one or more of the zones.
In one method, all flow control devices 32 can be closed, thereby preventing fluid flow 52 through all filters 24, and then one of the flow control devices can be opened to allow the fluid flows through a corresponding one of the filters. In this way, the properties of the fluid 52, which flows between the respective zone 28 and through the filter of the respective well 24, can be individually detected by means of the optical waveguide.

Invasion of water or gas, front of flood of water or steam, etc., in the individual zones can also be detected using this process.
Referring now to Figures 2A2C, an example of the longitudinal section of the pipe chain 12 is representatively illustrated. The illustrated section represents how flow through the filters in well 24 can be effectively controlled using the devices flow control 32. The section shown in Figures 2A-2C can be used in the system and pipe chain 12 of Figure 1, or it can be used in other systems and / or pipe chains.

OF THE PROPERTY
INDUSTRIAL flow control devices 32 to variably restrict flow through six of well filters 24. This demonstrates that any number of flow control devices 32 and any number of filters in well 24 can be used to controlling the flow of fluid 52 between one of zones 28 and the corresponding pipeline 12. The scope of this disclosure is not limited to any particular number or combination of the different components of the pipe chain 12.
Another flow control device 54 (such as a mechanically actuated sliding coaxial tubing valve, etc.) can be used to selectively allow and substantially prevent unrestricted flow through well 24 filters. For example, during Gravel packing operations, it may be desirable to allow unrestricted flow through the filters in well 24, for the circulation of slurry fluid returned to the earth's surface. In fracturing or other stimulation operations, flow control device 54 can be closed to thereby prevent flow a. through the filters 24 so that sufficient external pressure can be applied to the filters to force the fluid out into the corresponding zone 28.

One of the top devices
JNDU5TAi A i., Β is used to control the operation of an upper one of the flow control devices 32 (Figure 2A), and to control an intermediate one of the flow control devices (Figure 2B). A lower one of the hydraulic control devices 34 is used to control the actuation of a lower one of the flow control devices 32 (Figure 2C).
If the SCRAMS ™ device mentioned above is used for the hydraulic control devices 34, the signals transmitted through the power lines 50 are used to control the application of hydraulic pressure from the hydraulic lines to one selected from the flow control devices. 32. Therefore, the flow control devices 32 can be individually operated using the hydraulic control devices 34.
In Figure 2A, it can be seen that an inner tubular 60 is secured to an outer tubular 94 (eg, by threads, etc.), such that the inner tubular can be used to support a weight of a remainder of the pipeline 12 below.
Referring now further to Figure 3, an example of how one can
INDUSTRIAL • UV Λ- '' IVS use the flow control device the flow of the fluid 52 through the filter of the well 24. In this view, it can be seen that the fluid 52 enters the filter of the well 24 and flows into the an annular area 56 that is formed radially between a perforated base tube 58 of the well filter and an inner tube 60. Fluid 52 flows through annular area 56 to flow control device 32, which is contained within an outer tubular liner 62.
Flow control device 32 invariably restricts the flow of fluid 52 from annular area 56 for a flow passage 64 extending longitudinally through pipeline 12. Such a variable restriction can be used to balance production from the multiple zones 28, to prevent conicity of water or gas, etc. Of course, if fluid 52 is injected into zones 28, the variable constraint can be used to control a shape or extent of a water or steam flood front in the different zones, etc.
Referring now further to Figure 4, a way in which lines 50 can be routed through the pipeline is representatively illustrated.
12. In this view, overlay 62 is removed so that lines 50 extending from (and * & can be seen

Lines 50 extend from a connector 66 in flow control device 32 to an end connection of the well filter 24, where the lines are routed to another connector 70 to further extend the lines through pipeline 12. End connection 68 may be provided with flow passages (not shown) to allow fluid 52 to flow longitudinally through end connection from well filter 24 to flow control device 32 through annular area
56. Melting the end connection 68 can allow complex forms of flow passage and conduit in the end connection, but other means of manufacturing the end connection can be used, if desired.
Lines 50 may extend outside, and / or inside, a filter media (eg, wire wrap, wire mesh, sintered, prepackaged, etc.) of the well 24 filter. In some examples , the lines 50 could be positioned between the base tube 58 and the filter medium, radially inward of the filter medium, in the annular area 56, between the tubular 60 and the filter medium, etc.

In this example, termination kit 20 includes only one of each of well filter 24, flow control device 32 , the hydraulic control device 34 and the flow control device 54. However, as mentioned above, any number or combination of components can be used, according to the scope of this disclosure.
One difference in the example in Figure 5 is that the flow control device 54 and at least a portion of the flow control device 32 are positioned within the well filter 24. This can provide a longitudinally more compact configuration, and eliminate the use of the coating 62. Therefore, it can be appreciated that the scope of this disclosure is not limited to any particular configuration or arrangement of the components of the pipe chain 12.
Furthermore, it can be seen in Figure 5 that the hydraulic control device 34 can include the pressure sensor 36 that can be carried to the inner flow passage and / or to the outer ring 30 of the pipe chain 12. Multiple sensors can be provided pressure 36 in the

In some examples, pipe chain 12 can be installed in a single trip into well 14 with safety valve 4 6 (see Figure 1). Pipe chain 12 can be grounded into a wellhead above, and then plugs 26 can be fixed by applying internal pressure to the pipe chain. Pump 44 can be installed later, if desired (such as when production has decreased significantly, etc.). Lines 50 can be extended to a surface location, without any wet connections (eg, connections made inside the well) on lines 50.
Referring now further to Figure 6, another example of how flow control device 32 can be connected to hydraulic control device 34 is representatively illustrated. In this example, hydraulic control device 34 includes electronics 72 (such as, one or more processors, memory, batteries, etc.) sensitive to signals transmitted from a remote location (eg, a control station on the surface of land, a seabed facility, a floating drill rig, etc.) via lines 50 to direct the

The use of a flow control device (autonomous or remotely operated) may be preferable for injection operations, for example, if the precise regulation of flow resistance is not required. However, it should be appreciated that the scope of this disclosure is not limited to the use of any particular type of flow control device, or use of a particular type of flow control device in a particular type of operation.
Instead of, or in addition to, the pressure sensors 36, the separate pressure and / or temperature sensors can be transported into the pipeline 12 during the method described above, in which the characteristics and paths of fluid flow 52 flowing between the pipe chains and the individual zones

It can now be fully appreciated that the above disclosure provides significant advances in the matter of building and operating well completion systems. In the examples described above, improved well diagnoses are made possible by using a selectively variable flow control device 32 integrated with an external optical sensor (eg, optical waveguide as part of lines 50) to the pipe chain 12, and pressure sensors 36 carried on an interior and / or exterior of the pipe chain.
A system 10 for use with an underground well having multiple zones of land formation 28 is provided in the art by the disclosure above. In one example, system 10 may include: multiple filters from well 24 which filter fluid 52 flowing between a chain of pipe 12 in the well and the respective multiple zones 28; at least one optical waveguide 50 that detects at least one property of the fluid 52 as it flows between the pipe chain 12 and at least one of the zones 28;
multiple flow control devices 32 that restrict mu_

Examples can receive fluid 52 from the respective multiple well filters 24.
The optical waveguide 50 can be positioned external to the well 24 filters and / or internal to the well filters (eg, between the base tube 58 and a filter medium of the well 24 filters, radially toward inside the filter medium, in the annular area 56, between the tubular 60 and the filter medium, etc.). The optical waveguide 50 can be positioned between the filters in well 24 and zones 28.
A pipeline chain for use in an underground well was also previously described. In one example, pipeline chain 12 may include at least one filter from well 24; at least a first flow control device
54; and at least one second flow control device 32, the second flow control device 32 is remotely operable. The first flow control device 52 selectively prevents and substantially allows unrestricted flow through well filter 24. The second flow control device 32 variably restricts flow through well filter 24.
The pipeline 12 may include a hydraulic control device 34 that controls the application of hydraulic actuation pressure to the second control device "S ki.

The second flow control device 32 can comprise multiple second flow control devices 32, and the hydraulic control device 34 can control the application of hydraulic actuation pressure to the multiple second flow control devices 32.
Pipeline 12 may include at least one optical waveguide 50 that is operative to detect at least one property of a fluid 52 flowing through the well filter 24.
Also described above is a method of operating a pipeline chain 12 in an underground well. In one example, the method may comprise: closing all the multiple flow control devices 32 connected in the pipe chain 12, the pipe chain 12 includes multiple well filters 24 that filter the fluid 52 flowing between the pipe chain 12 and the multiple zones of formation of respective ground 28, at least one optical waveguide 50 that detects at least one property of the fluid as it flows between the pipe chain 12 and at least one of the zones 28, the multiple flow control devices 32 that variably restrict the

fluid flow 52 through the respective multiple well filters 24, and multiple pressure sensors 36 that detect the pressure of the fluid 52 flowing through the respective multiple well filters 24; at least partially open a first selected flow control device 32; and measuring a first change in property detected by optical waveguide 50 and a first change in fluid pressure 52 as a result of opening of the first selected flow control device 32.
The method may also include: closing all multiple flow control devices 32 after the step of at least partially opening the first of the selected flow control devices 32; at least partially open a second selected flow control device; and recording a second change in property detected by optical waveguide 50 and a second change in fluid pressure 52 as a result of opening of the selected second flow control device 32.
The method may include installing the multiple filters in the well 24, the optical waveguide 50, the multiple flow control devices 32, and the multiple pressure sensors 36 in the well on a single trip into the well.
