Description

COMPLETION SYSTEM THAT HAS A SAND CONTROL ASSEMBLY, AN INDUCTIVE COUPLER, AND AN ADJACENT DETECTOR TO THE SAND CONTROL ASSEMBLY TECHNICAL FIELD The invention relates generally to a completion system having a completion section having a sand control assembly to prevent the passage of material particles, an inductive coupler, and a detector placed adjacent to the control assembly ground and electrically connected to the inductive coupler portion. BACKGROUND OF THE INVENTION A completion system is installed in a well to produce hydrocarbons (or other types of fluids) from the well (s) adjacent to the well, or to inject fluids into the well. The detectors are typically installed in completion systems to measure various parameters, including temperature, pressure and other well parameters. However, the implementation of detectors is associated with several challenges, particularly in the wells where sand control is desired. BRIEF DESCRIPTION OF THE INVENTION In general, a completion system for use in a well includes a first completion section having a sand control assembly to prevent the passage of material particles, a first portion of the inductive coupler, and a detector placed adjacent to the control assembly of sand and electrically connected to the first portion of the induction coupler. A second section can be implemented after the installation of the first completion section, where the second section includes a second portion of the inductive coupler to communicate with the first portion of the inductive coupler to allow communication between the detector and other components coupled to the second section.

DETAILED DESCRIPTION OF THE INVENTION In the following description several details are defined to provide an understanding of the present invention. However, it will be understood by those skilled in the art that the present invention can be practiced without these details and that numerous variations or modifications of the described modalities are possible. As used herein, the terms "above" and "below"; "up and down"; "upper" and "lower", "up" and "down"; and other similar terms indicating the relative positions above or below a given point or element are used in this description to more clearly describe the embodiments of the invention. However, when applied to equipment and methods for use in wells that are offset or horizontal, such terms may refer to a left to right, right to left, or diagonal relationship, as appropriate. According to some modalities, a completion system is provided for installation in a well, where the completion system makes it possible to monitor in real time the downhole parameters such as temperature, pressure, flow, fluid density, the reservoir resistivity, oil / gas / water ratio, viscosity, carbon / oxygen ratio, acoustic parameters, chemical detection (such as slag, paraffin, asphaltenes, deposition, pH detection, salinity detection), and so on . The well can be an offshore well or a well based on land. The completion system includes a detector assembly (such as in the form of an array of detectors of several detectors) that can be placed in various positions along a sand wall of a well, in some embodiments. A "sand wall" refers to a region of the pit that is not covered with a pipe or liner. In other embodiments, the detector assembly can be placed in a cased or jacketed section of the well. "Real-time monitoring refers to the ability to observe the parameters of the bottom of the well during some operation carried out in the well, such as during the production or injection of fluids or during an intervention operation. detectors are placed in discrete locations at various points of interest.Also, the detector assembly can be placed either outside or inside a sand control assembly, which can include a sand baffle, a slotted or perforated coating, or a Slotted or perforated tube.

The detectors can be placed adjacent to a sand control assembly. A detector is "adjacent" to a sand control assembly if it is in an area in which the sand control assembly is conducting the control of the material particles. In some embodiments, a completion system having at least two stages (a higher completion section and a lower completion section) is used. The lower completion section is first placed in the well in a first maneuver, where the lower completion section includes the detector assembly. An upper completion section is then placed in a second maneuver, where the upper completion section can be connected inductively with the first completion section to allow communication and power supply between the detector assembly and other components that are located well above the detector assembly. The inductive coupling between the upper and lower completion sections is called a wet connection mechanism inductively coupled between the sections. "Wet connection" refers to the electrical connection between the different stages (it refers to an electrical connection between the different stages (placed at different times) of a completion system, in the presence of well fluids. wet connection mechanism connected inductively between the upper and lower completion sections allows the power supply and signaling to be established between the detector assembly and the uphole components, such as a component located elsewhere in the well borehole on the earth's surface. It should be understood that the term two-stage completion should include those completions where additional completion components are placed after the first top completion, as is commonly used in coated well frac pack applications. In such wells, the inductive coupling can be used between the lower completion component and the above completion component, or other interfaces can be used between the components of the completion. A plurality of inductive couplers may also be used in the case where there are several interfaces between the completion components. Induction is used to indicate the transfer of an electromagnetic signal or energy that changes over time which does not depend on a closed electrical circuit, but instead includes a component that is wireless. For example, if a current that changes over time is passed through a coil, then a consequence of the variation in time is that an electromagnetic field will be generated in the medium surrounding the coil. If a second coil is placed in the electromagnetic field, then a voltage will be generated in the second coil, which is designated as induced voltage. The efficiency of this inductive coupling increases when the coils are placed closer together, but it is not a necessary restriction. For example, if the current that changes with time is passed through a coil that winds around a metal mandrel, then a voltage will be induced in a coil wound around the same mandrel at some distance displaced from the first coil. In this way, a single transmitter can be used to supply power or communicate with the various detectors along the wellbore. Given enough energy, the transmission distance can be very large. For example, solenoid coils on the surface of the earth can be used to communicate inductively with the underground coils deep in a drill hole. Also note that the coils should not be rolled up as solenoids. Another example of inductive coupling occurs when a coil is wound like a toroid around a metal mandrel, and a voltage is induced in a second toroid withdrawn some distance from the first.

In alternative embodiments, the detector assembly may be provided with the upper completion section in place than with the lower completion section. In still other modalities, a one-stage completion system may be used. Although reference is made to the sections of completion that are capable of providing power to the lower completion sections through inductive couplers, it is noted that lower completion sections can obtain power from other sources, such as batteries, or power sources that collect energy from vibrations (for example, vibrations in the completion system). Examples of such systems have been described in the North American Publication No. 2006/0086498. The energy sources that collect energy from the vibrations can include an energy generator that converts the vibrations into energy that is then stored in a charge storage device, such as a battery. In the event that the lower complementation obtains energy from other sources, the inductive coupling will still be used to facilitate communications through the components of the completion.

Reference is made to Figs. 1A, 2, and 3 in the subsequent discussion of a two-stage completion system according to one modality. Fig. 1A shows the two-stage completion system with a top-completion section 100 (Fig. 3) connected with a lower-completion section 102 (Fig. 2). The two-stage completion system is a sand wall completion system that is designed to be installed in a well having a region 104 that is not encased or lined ("open well region"). As shown in Fig. 1A, the openwell region 104 is below a coated or jacketed region having a coating or shell 106. In the openwell region, a portion of the completion section 102 is provided adjacent to a sand wall 108. To prevent passage of the material particles, such as sand, a sand baffle 110 is provided in the lower completion section 102. Alternatively other types of sand control assemblies can be used, including slotted or perforated pipes or slotted or perforated liners. A sand control assembly is designed to filter particles, such as sand, to prevent such particles from flowing from a surrounding reservoir to a well. According to some embodiments, the lower section 102 e has a detector assembly 112 having several 114 detectors placed in various locations discrete through the sand wall 108. In some embodiments, detector assembly 112 is in the form of a detector wire (also referred to as "detector flange"). The detector wire 112 is basically a continuous control line having portions in which the detectors 114. are provided. The detector wire 112 is "continuous" in the sense that the detector wire provides a continuous seal against fluids, such Like the fluids, from a drilling well, along its length. Note that in some embodiments, the continuous detector cable may actually have discrete housing sections that connect in a sealing manner. In other embodiments, the detector cable can be implemented with a continuous, integrated housing, without interruptions. In the lower completion section 102, the detector cable 112 is also connected to a controller cartridge 116 that can communicate with the detectors 114. The controller cartridge 116 is capable of receiving commands from another location (such as the surface of the earth or from another location in the well, for example, from the control station 146 in the upper completion section 100). These commands can instruct the cartridge 116 of the controller to cause the sensors 114 to take measurements or transmit the measured data. Also, the cartridge 116 of the controller is capable of storing and communicating the data of the detectors 114. Therefore, at periodic intervals, or in response to the commands, the cartridge 116 of the controller is able to communicate the data of the measurements to another component (e.g., the control station 146) which is located elsewhere in the well or on the surface of the earth. In general, the cartridge 116 of the controller includes a processor and storage. The communication between the detectors 114 and the cartridge 116 of the controller can be bi-directional or can use a master-slave arrangement. The cartridge 116 of the controller is electrically connected to a first portion 118 of the inductive coupler (e.g., a female portion of the coupler). inductive) that is part of the lower completion section 102. As discussed further below, the first portion 118 'of the inductive coupler allows the lower completion section 102 to communicate electrically with the upper completion section 100 such that the commands can be output to the cartridge 116 of the controller and the cartridge 116 of the controller. it is capable of communicating the data of the measurements to the upper completion section 100. In the modes in which the energy is produced or generated locally in the lower completion section, the cartridge 116 of the controller may include a battery or a power source. As further shown in Figs. 1A and 2, the lower termination section 102 includes a packer 120 (eg, a gravel packer packer) which when adjusted makes a seal against the liner 106. The packer 120 isolates an annular region 124 under the packer 120, wherein the annular region 124 is defined between the outside of the lower termination section 102 and the inner wall of the liner 106 and the sand wall 108. A sealed bore assembly 126 extends below the packer 120, where the sealed bore assembly 126 must sealingly receive the upper completion section 100. The sealed hole assembly 126 is additionally connected to a circulation orifice assembly 128 having a sliding sleeve 130 which slides to cover or uncover the circulation holes in the mounting of circulation orifices 128. During a gravel packing operation, the sleeve 130 can be moved to an open position to allow the gravel suspension to pass from the internal perforation 132 of the lower termination section 102 to the annular region 124 to carry out the packing of the gravel. Gravel of the annular region 124. The packaging of gravel formed in annular region 124 is part of the sand control assembly designed to filter the particles. In the exemplary implementation of Figs. 1A and 2, the lower termination section 102 further includes a mechanical fluid loss control device, for example, the isolation valve 134 of the formation, which can be implemented as a ball valve. When closed, the ball valve isolates a lower portion 136 from the internal bore 132 of the perforation portion 132 internal above the isolation valve 134 of the formation. When opened, the isolation valve 134 of the formation can provide an open bore to allow the flow of the fluids as well as the passage of the intervention tools. Although the lower termination section 102 shown in the example of Figs. 1A and 2 includes several components. It is noted that in other implementations, some of these components can be omitted or replaced with other components. As shown in Figs. 1A and 2, the detector cable 112 is provided in the annular region 124, outside the sand baffle 110. By implementing the detectors 114 of the detector cable 112 outside the sand baffle 110, control emissions and fluid losses can be avoided by using the isolation valve 134 of the formation.

Note that the isolation valve 134 of the formation can be closed for the purpose of controlling the loss of fluids during the installation of the two-stage completion system. As shown in Figs. 1A and 3, the upper completion section 100 has a fork seal assembly 140 for sealing the coupling within the sealed bore assembly 126 (Fig. 2) of the lower completion section 102. As shown in FIG. 1A, the outer diameter of the fork seal assembly 140 of the upper completion section 100 is slightly less than the internal diameter of the sealed bore assembly 126 of the lower completion section 102. This allows the fork seal assembly 140 of the upper completion section to slide in a sealing manner within the sealed bore assembly 126 of the lower completion section (which is shown in Fig. 1A). In an alternative embodiment, the fork seal assembly can be replaced with a cartridge holder that must not be sealed. As shown in Fig. 3, disposed on the outside of the fork seal assembly 140 of the upper completion section is a press-latch latch that enables engagement with the packer 120 of the lower completion section 102. When the latch 142 When the pressure seal is engaged in the packer 120, as shown in FIG. 1A, the upper completion section 100 securely engages the lower completion section 102. In other implementations other coupling mechanisms may be used in place of the snap latch 142. Near the lower portion of the upper completion section 100 (and more specifically near the lower portion of the fork seal assembly 140) is a second portion 144 of the inductive coupler (e.g., a male portion of the inductive coupler). When placed close to each other, the second portion 144 of the inductive coupler and the first portion 118 of the inductive coupler (as shown in FIG. 1A) form an inductive coupler which makes it possible to communicate inductively coupled data and energy, between the upper and lower completion sections. An electrical conductor 147 (or conductors) extend from the second portion 144 of the inductive coupler to the control station 146, which includes a processor and a power and telemetry supply module (for supplying the power and for communicating the signaling with the cartridge 116 of the controller in the lower completion section 102 through the inductive coupler). The control station 146 it may also optionally include detectors, such as temperature and / or pressure detectors. The control station 146 is connected to an electrical cable 148 (e.g., a twisted pair electrical cable) extending upward to a shrinkage joint 150 (or length compensation joint). In the shrinkage joint 150, the electric wire 148 can be wound in a spiral fashion (to provide a helically wound wire) until the electric wire 148 reaches a top packer 152 in the upper completion section 100. The upper packer 142 in a packer with holes to allow the electrical wire 148 to extend through the packer upwardly of the packer 152 with holes. The electrical cable 148 can extend from the upper packer 152 to the land surface (or to another location in the well). In another embodiment, the control station 146 may be omitted, and the electrical cable 148 may run from the second portion 144 of the inductive coupler (of the upper completion section 100) to a control station in another part of the well or in the terrestrial surface. The shrinkage joint 150 is optional and may be omitted in other implementations. The upper completion section 100 also includes a pipe 154, which It can extend to the earth's surface. The upper completion section 100 is carried by the well in the line 154. In operation, the lower completion section 102 is placed in a first maneuver in the well and installed near the open hole section of the well. The packer 120 (Fig. 2) is then adjusted, after which a gravel packing operation can be carried out. To carry out the gravel packing operation, the circulation orifice assembly 128 is operated to an open position to open the orifice (s) of the circulation orifice assembly 128. A suspension of gravel is then communicated into the well and through the open orifice (s) of the circulation orifice assembly 128 to the annular region 124. The annular region 124 is then filled with the suspension until the annular region 124 is packed with gravel. Next, in a second maneuver, the upper completion section 100 is placed in the well and connected to the lower completion section 102. Once the upper and lower completion sections are coupled, communication between the controller cartridge 116 and the control station 146 can be carried out through the inductive coupler which includes the portions 118 and 114 of the inductive coupler. The control station 146 sends the commands to the cartridge 116 of the controller in the lower completion section 102, or the control station 146 can receive the measurement data collected by the detectors 114 of the controller cartridge 116. Fig. IB shows a slightly different view of the two-stage completion system shown in Fig. 1A. In FIG. IB, the detector cable 112, the controller cartridge 116, and the control station 146 are shown in slightly different views. Functionally, the completion system of Fig. IB is similar to the completion system of Fig. 1A. Fig. 1C is a schematic diagram of an exemplary electric chain between the detectors 114 that are part of the lower completion section 102 and a surface controller 170 (provided on the land surface). The detectors 114 communicate through a data line 172 that is part of the detector cable 112, with the cartridge 116 of the controller. The communication between the controller cartridge 116 and an interface 174 of the control station (part of the control station 146) occurs through the portions 118, 114 of the inductive coupler (as discussed above). A switch 176 can be provided in the controller cartridge 176 to control if communication is allowed through the portions, 118 and 144, of the inductive coupler or not. The switch 176 can be controlled by the control station 146 or in response to commands sent from the surface controller 176 through the control station 146. Note that, as discussed above, the control station 146 may be omitted in some implementations, with the surface controller 170 being able to communicate with the controller cartridge 116 without the control station 146. The control station 146 communicates the power and signaling through the electrical cable 148 to a interface 177 of the communication bus or bus. In one implementation, the interface 177 of the communication bus or manifold may be a ModBus interface, which is capable of communicating via a ModBus communication link 178 with the surface controller 170. The ModBus communication link 178 may be a serial link implemented with RS-422, RS-485, and / or RS-232, or alternatively, the ModBus communication link 178 may be a TCP / IP (Transmission Control Protocol / Internet Protocol). The ModBus protocol is a standard communications protocol in the oilfield industry and specifications are widely available, for example at www. modbus. org. In implementations alternatives, other types of communication links can be used. In one implementation, detectors 114 can be implemented as slave devices that respond to requests from control station 146. Alternatively, the detectors 114 may be able to initiate communications with the control station 146 or with the surface controller 170. In one embodiment, communications through the portions, 118, and 144, of the inductive coupler is achieved by using frequency modulation of the data signals around a particular frequency carrier. The frequency carrier has sufficient energy to supply power to the cartridge 116 of the controller and the detectors 114. Alternatively, the cartridge 176 of the controller and the detectors 114 may be powered by a battery. The detectors 114 may be analyzed periodically, such as once each predetermined time interval. Alternatively, the sensors 114 are evaluated in response to a specific request (such as from the control station 146 or the surface controller 179) to retrieve the measurement data. "Fig. ID illustrates yet another variant of the two-stage completion system. In the embodiment of Fig. 1A, uses a single inductive coupler to provide both power and signal (data) communication. However, according to FIG. ID, two inductive couplers are used, an inductive coupler 180 for power supply and an inductive coupler 182 for data communication. Fig. 1E shows another embodiment using two couplers, 184 and 186, inductive for power supply and data communication with a first detector cable 188, and the second inductive coupler 186 for providing power supply and communication of data with a second cable 190 of detectors. The use of two inductive couplers and two corresponding detector cables in the mode of Fig. 1E provides redundancy in the event of failure of one of the detector cables or one of the inductive couplers. The cables, 188 and 190, of detectors are generally parallel to one another. However, the detectors 192 of the detector wire 188 often bifurcate along the longitudinal direction of the well with respect to the detectors 194 of the detector wire 190. In other words, in the longitudinal direction each detector 192 is placed between two successive detectors 194 (see dotted line 196 in FIG. 1E). Similarly, each detector 194 is placed between two successive detectors 192 (see broken line 198). in Fig. 1E). By providing the longitudinal misalignment of the detectors 192 and 194, the sensors 192 and 194 are capable of collecting the measurements at different depths in the well. In this way, the effective density of the detectors in the region of interest increases if both detector cables 188 and 190 are operational. In another embodiment, the detector wires 188 and 190 may be placed in series instead of in parallel as shown in Fig. 1E. in yet another arrangement, the place of both cables 188 and 190 which are detector cables, one of the cables may be a cable used to provide control, such as a flow control device (or alternatively, one of the cables may be a combination of detector and control cables). In the modes discussed above, a cable provides electrical cables that interconnect the various detectors in a collection or array of detectors. In an alternative implementation, the cables between the detectors may be omitted. In this case, several portions of the inductive coupler can be provided for the corresponding detectors, with the upper completion section providing corresponding portions of the inductive coupler to interact with the portions of the Inductive coupler associated with the respective detectors to transmit the energy and data with the detectors. In addition, even though reference has been made to the communication of data between the detectors and other components in the well, it is noted that in the alternative and particulate implementations in the implementations where the detectors are provided with their own sources of power in the background From the well, the detectors can only provide sufficient micro-energy for the detectors to make the measurements and store the data for a relatively long period of time (eg, months). Later, an intervention tool can be lowered to communicate with the detectors to recover the collected measurement data. In one embodiment, communication between the intervention tool would be achieved using the inductive coupling, wherein a portion of the inductive coupler is permanently installed at completion, and the coupled inductive coupler portion is in the intervention tool. The intervention tool could also replenish (for example, charge) the sources of energy from the bottom of the well. Fig. 4 illustrates a different embodiment of a two-stage completion system in which the positions of the inductive coupler and of the control station have been changed. The completion system includes a top completion section 100A and a bottom completion section 102A. In the embodiment of Fig. 4, the first portion 118 of the inductive coupler is provided above a packer 204 (a packer with holes) of the lower completion section 102A. The first portion 118 of the inductive coupler can be electrically connected in turn to the controller cartridge 116 (located below the packer 204), which is connected to a detector wire 112A. The detector wire 112A has a portion passing through a hole in the packer 204 with holes to allow communication between the detectors 114 and the cartridge 116 of the controller. The upper completion section 100A has a lower section 208 that provides the second portion 144 of the inductive coupler for communicating with the first portion 118 of the inductive coupler when the upper completion section 100A engages the lower completion section 102A. In the embodiment of Fig. 4, control station 146 is provided above packer 152 with holes (as compared to the position of control station 146 below packer 152 with holes in Figs 1A and 3).

The remaining components depicted in Fig. 4 are the same or similar to the corresponding components in Figs. 1A, 2 and 3 and therefore are not described further. Fig. 5 shows yet another variant of the two-stage completion system which includes a top completion section 100B and a lower completion section '102B. In this embodiment, a detector cable 112B similar to the detector cable 112 of FIG. 1A extends higher in the lower completion section 102B to the controller cartridge 116 which in turn connects to the first portion 118 of the inductive coupler. . The first portion 118 of the inductive coupler is placed higher in the lower completion section 102B (as compared to the lower completion section 102 of Fig. 1A) such that a fork seal assembly 140B of the completion section 100B The top should not extend deeply into the lower completion section 102B. As a result, when inserted into the lower completion section 102B, the fork seal assembly 140B of the upper completion section 100B does not extend beyond the mounting 128 of the circulation hole, such that the circulation orifice 128 is not blocks when the upper completion section 100B engages the lower completion section 102B. In the embodiment of Fig. 5, the portions, 188 and 144, of the inductive coupler are placed above the mounting 128 of the circulation hole. In the arrangement of Fig. 5, the control station 146 is also provided above the packer 152 with holes as in the embodiment of Fig. 4. Fig. 6 shows a multi-stage completion system according to another embodiment which includes a higher completion section 100C and a lower completion section 102C that has multiple parts for multiple zones in the well. As shown in Fig. 6, three zones, 302, 304, and 306, of production (or injection zones) are represented. The completion section 102C has three groups of cables 308, 310, and 312 of detectors that are similar in arrangement to the detector cable 112 of FIG. 1. Each detector cable 308, 310, 312 has several detectors at discrete locations in the detector. the zones 302, 304, 306, respectively. In the arrangement of Fig. 6, the zones 302, 304, and 306 are all aligned with the liner 314, unlike the open-hole section shown in Fig. 1. The liner 314 is pierced in each of the zones 302, 304, and 306 to allow communication between the well and the reservoirs adjacent to the well. The lower completion section 102C includes a first lower packer 316 that provides insulation between the zones 304 and 306, and a second packer 318 providing insulation between the zones 304 and 302. The lower detector wire 312 is electrically connected to a first group of portions 318 and 320 of the inductive coupler. The portion 318 of the inductive coupler is connected to a tube or baffle section that is attached to the first packer 316. On the other hand, the portion 320 of the inductive coupler is joined to another section 324 of the tube or baffle that extends upward to join to another section 326 of tube. In the second zone 304, a second group of inductive coupler portions 328 and 330 is provided, where the portion 328 of the inductive coupler is attached to the tube section 326. On the other hand, the portion 330 of the inductive coupler is attached to the pipe section 332 extending upward to the isolation valve 134 of the formation of the lower completion section 102C. The remaining portions of the lower completion section 102C are similar or the same as in the lower completion section 102B of Fig. 5. the upper completion section 100C that connects to the lower completion section 102C is also similar to the same as the upper completion section 100B of FIG. 5. In the operation, the lower completion section 102C is installed in different maneuvers, with the more low of the lower completion section 102C (corresponding to the lowest zone 306) installed first, followed by the second part of the lower completion zone 102C that is adjacent to the second zone 304, followed by the section part 102C of lower completion adjacent to zone 302. The power supply and data communication between the controller cartridge 116 and the detectors of the detector cables 310 and 312 is carried out through the inductive couplers corresponding to the portions 328. , 330, and 318, 320. FIG. 7 shows the completion system according to yet another embodiment including a lower completion section 402 and a higher completion section 400. A liner 425 covers a portion of the well. In the embodiment of FIG. 7, an inductively connected wet connection mechanism is not used, unlike the embodiments of FIGS. 1A-6. In Fig. 7, lower completion section 402 includes a gravel packing packer 404 that attaches to a circulation orifice assembly 406. The lower completion section 402 also includes a valve 408 for insulating the formation below the orifice assembly 406. A sand baffle 410 is attached below the isolation valve 408 of the Training for sand control or particle control. The lower completion section 402 is positioned adjacent to an open well zone 412 in which production (or injection) is carried out. Note that in the embodiment of Fig. 7, the lower completion section 402 does not include an inductive coupler portion. In the embodiment of Fig. 7, the upper completion section 400 has an electrode holder that is composed of a slotted tube having several slots to allow communication between the inner hole of the electrode holder 414 and the outside of the electrode holder 414. The electrode holder 414 it extends into the lower completion section 402 in the vicinity of zone 412 of the open well. Within the electrode holder 414 is disposed a sensor cable 416 having several detectors at discrete locations through the area 412. The detector cable 416 extends upwardly in the electrode holder 414 until it emerges at the upper end of the electrode holder 414. The sensor cable 416 extends radially through an individual gasket 419 slotted to a packer 420 with holes in the upper completion section 400. The individual slotted board 419 has slots 428 that are outside the upper completion section 400 and below the packer 420.

In the upper completion section 400, a control station 430 is provided above the packer 420. The detector cable 416 extends through the packer 420 with holes to the control station 430. The control station 430 is in turn communicated through an electrical cable 432 to a location on the land surface or other location in the well. Unlike the embodiments shown in Fig. 1A-6, the detectors 418 of the embodiment of Fig. 7 are arranged within the sand control assembly (rather than on the outside of the sand control assembly). However, the use of the electrode holder 414 makes it possible to conveniently place the detectors 418 through the sand wall adjacent the sand baffle 410. In operation, the lower completion section 402 is first installed in the well adjacent to the area 412. Following the gravel packing, the upper completion section 400 is placed in the well, with the electrode holder 414 inserted in the section 402 of lower completion such that the detectors 418 of the detector cable 416 are positioned near the area 412 in several discrete locations. In some modalities the lower completion section may not require the packing of gravel; instead, the lower completion section it may include an expandable deflector, a drilled and coated hole, a slotted liner, or an open bore. FIG. 8A shows yet another arrangement of a two-stage completion system having an upper completion section 400A and a lower completion section 402A in which an inductively connected wet connection mechanism is not used. A recoverable electrode holder 414A that is part of the upper completion section 400A is inserted into the lower completion section 402A. The lower completion section 402A is similar to, or identical to, the lower completion section 402 of Fig. 7. However, the electrode holder 414A in Fig. 8A has a longitudinal groove on its outer surface in which a 416A cable of detectors. A transverse view of a portion of the electrode holder 414A with the detector cable 416A is shown in Fig. 9. As shown in Fig. 9, a longitudinal groove (or dent) 440 is provided on the outer surface of the electrode holder 414A such that the detector cable 416A can be placed in the slot 440. Referring again to FIG. 8A, the detector cable 416A extends upward until it reaches a hanger 442 of the electrode holder that rests in a receptacle 444 of the detector. electrode holder of a 419A individual grooved gasket.

The sensor cable 416A extends radially through the hanger 442 of the electrode holder and the individual gasket 419A grooved in a region outside the outer surface of the upper completion section 400A. The detector cable 416A extends through the packer 420 with holes to the control station 430. Basically, the difference between the embodiment of Fig. 8A and the embodiment of Fig. 7 is that the detector cable 416A is disposed outside the electrode holder 414A (instead of inside the electrode holder). Also, the electrode holder 414A can be recovered since it rests within the receptacle 444 of the electrode holder on a hanger 442 of the electrode holder. (Fig. 7 shows a fixed electrode holder that is part of the upper completion section 400). An intervention tool can be placed in the well to hold the hanger 442 of the electrode holder of Fig. 8A to retrieve the hanger 442 from the electrode holder with the electrode holder 414A from the well. As shown in Fig. 8A, a locking mechanism 446 is provided to lock the hanger 442 of the electrode holder to the receptacle 444 of the electrode holder. In an exemplary implementation, locking mechanism 446 may be a snap latch mechanism. Another difference between the upper completion section 400A of Fig. 8A and the completion section 400 upper of FIG. 7 is that the upper completion section 400A has a slotted tube section 448 that extends below the receptacle 444 of the electrode holder. The slotted tube section 448 extends to the lower completion section 402A, as shown in FIG. 8A. Fig. 8B illustrates another variant of the two-stage completion system that also employs a recoverable electrode holder 414B. The electrode holder 414B extends from a hanger 442B of the electrode holder resting in a receptacle 444B of the electrode holder. The difference between the embodiment of Fig. 8B and the embodiment of Fig. 8A is that the hanger 442B of the electrode holder has a first portion 450 of the inductive coupler (the male portion of the inductive coupler) which is capable of being inductively coupled to the second portion 452 of the inductive coupler (the female portion of the inductive coupler) within the receptacle 444B of the electrode holder. A detector cable 416B (which also runs out of the electrode holder 414B but in a longitudinal groove) extends upwards and connects to the first portion 450 of the inductive coupler in the hanger 442B of the electrode holder. When the hanger 442B of the electrode holder is installed within the receptacle 444B of the electrode holder, the first and second portions, 450 and 452, of the inductive coupler are placed adjacent to each other so that signaling and electrical power can be inductively connected between the portions 450 and 452 of the inductive coupler. The second portion 452 of the inductive coupler is connected to an electrical cable 454 which passes through the packer 420 with holes to the control station 430 above the packer 420. In operation, the lower completion section 402B is first placed in the well, followed by section 400B of top completion in a separate maneuver. Then, the electrode holder 414B is placed in the well, and is installed in the receptacle 444B of the electrode holder of the upper completion section 400B. Fig. 10 illustrates yet another embodiment of another completion system that provides detectors in a production (or injection) zone. In the embodiment of FIG. 10, detectors 502 are provided outside a liner 504 that lines the well. The detectors 502 are also part of the detector cable 506. The detectors 502 are provided in various discrete locations outside the sheath 504. The detector wire 506 runs upward to a first portion 508 of the inductive coupler (the female portion of the inductive coupler) through a controller cartridge 507. The 508 portion of the coupler inductive interacts with a second portion 510 of the inductive coupler (the male portion of the inductive coupler) to communicate energy and data. The portion 508 of the inductive coupler is located outside the liner 504, while the second portion 510 of the inductive coupler is located within the liner 504. Within the liner 504, a packer 512 is fixed to isolate an annular region 514 that is above the packer 512 and between a pipe 516 and the liner 504. The second portion 510 of the inductive coupler is electrically connected to a control station 518 through an electrical wire section 520. In turn, the control station 518 is connected to another electrical cable 522 that can be extended to the land surface or elsewhere in the well. In operation, the liner 504 is installed in the well with the detector cable 506 and the portion 508 of the inductive coupler provided with the liner 504 during installation. Subsequently, after the liner 504 has been installed, the completion equipment can be installed within the liner, including those shown in Fig. 10. Before or after the installation of the components depicted in Fig. 10, a spray gun is provided. Drilling can be lowered into the well to the 500 production (or injection) zone. The drill gun can to be activated later to produce the perforations 526 through the liner 504 and to the surrounding formation. Directional drilling can be carried out to avoid damage to the detector cable 506 which is located outside the liner 504. Fig. 11 illustrates yet another different arrangement of the completion system, which is similar to the completion system of Fig. 10 except that the completion system of Fig. 11 has multiple stages to correspond with multiple different zones 602, 604 and 606. In the embodiment of Fig. 11, a detector cable 506A is also provided outside the liner 504, with the detector cable 506A having detectors 502 provided at various locations in the different zones 602, 604 and 606. The cable 506A of detectors extends to the first portion 508 of the inductive coupler through the cartridge 507 of the controller. The completion system of Fig. 11 also includes the packer 512, the second portion 510 of the inductive coupler, the control station 518, and the electrical cable sections 520 and 522, as in the embodiment of Fig. 10. The embodiment of Fig. 11 differs from the embodiment of Fig. 10 because the additional completion equipment is provided below the packer 512. In Fig. 11, a packer 608 of the gravel packing, with a circulation hole assembly 610 provided below the packer 608 of the gravel packing. A formation isolation valve 612 is also provided below the mounting 610 of the circulation hole. Additional equipment below the formation isolation valve 612 includes sand baffles 614 and insulation packers 616 and 618 to isolate zones 602, 604 and 606. FIG. 12 illustrates another embodiment of a termination system utilizing a Electrode holder design that does not use a wet connection mechanism connected inductively. The completion system includes a higher completion section 700 and a lower completion section 702. In Fig. 12, a packer 704 of the gravel pack is fixed in a production (or injection) zone, with a sand baffle 706 attached below the packer 74. The packer 704 of the gravel pack and deflector 706 they are part of section 702 of inferior completion. The upper completion section 700 includes an electrode holder 708 (which includes a perforated tube). Several detectors 710 and 712 are disposed inside the internal hole 708 of the electrode holder. The detectors 710 and 712 are connected by means of connections And to an electric cable 714. The electric cable 714 runs through the sealing pieces 716 and 720 connected in Y and exits to the upper end of the electrode holder 708. The electric cable 714 extends radially through an auxiliary 722 with holes and then passes through the packer 724 with holes in the completion section 700 greater than a control station 726. The control station 726 is in turn connected by an electric cable 728 to the land surface or to another location in the well. Fig. 13 shows a portion of a detector cable 800 according to one embodiment, which can be any of the detector cables mentioned above. The sensor cable 800 includes external housing sections 802 and 804, which are sealingly connected to a detector housing structure 806 that houses a detector support 810 and a detector 808. The sensors 808 are placed in a camera 909 of the detector support 810. The housing 806 of the detector support and the housing sections 802 and 804 of the detector cable 800 can be formed of metal. The housing sections 802, 804 can be welded to the detector support housing 806 to provide a sealing coupling (to prevent fluids from flowing into the well 800 from the well). detectors). The support 810 of the detector can also be formed from a metal to act as a frame. As an example, the metal used to form the support 810 of the detector can be aluminum. Similarly, the metal used to form the sections 802, 804 of the housing and the housing 806 of the detector support can also be aluminum. If the detector 808 is a temperature detector, then the aluminum is a relatively good thermal coupler to allow accurate temperature measurement. However, in other implementations, other types of metals may be used. Also, non-metallic materials can also be used to implement elements 802, 804, 806, and 810. As further shown in FIG. 13, detector 808 includes an integrated circuit 812 of the detector (e.g., an integrated circuit of the detector for measuring the temperature) and a communications interface 814 (electrically connected to the integrated circuit 812 of the detector) to allow communication with the electrical cables 816 and 818 that extend in the detector cable 800. In an exemplary implementation, the communication interface 814 is an I2C interface. Alternatively, other types of communication interfaces can be used with the 808 detector. The circuit 812 integrated detector and 8145 interface can be mounted on a circuit board 811 in one implementation. The portion shown in FIG. 13 is repeated along the length of the detector wire 800 to provide several detectors 808 along the detection wire 800 at several discrete locations. According to some embodiments, the detector cable 800 is implemented with bi-directional twisted pair cables, which have relatively high noise immunity. The signals on the twisted pair cables are represented by differences in voltages between the two cables. The successive housing sections 802, 804 and the housing structures 806 of the detector are collectively referred to as "the outer shell" of the detector wire 800. One benefit of using solder on the detector wire is that O-rings, or discrete metal seals, can be avoided. However, in other implementations, O-rings or metal seals may be used. In an alternative implementation, instead of using welding to weld the sections 802, 804 of the housing with the detector support housing 806, other forms of sealing engagement or sealing adhesion may be provided between the two. sections 802, 804 of the housing, and housing 806 of the detector support. Fig. 14 illustrates a detector cable 800A according to a different embodiment. In this embodiment, the sections 802, 804 of the detector cable detector 800A are sealingly connected to a detector support housing 806A having an outer diameter wider than the outer diameter of the housing sections 802, 804. In other words, the detector support housing 806A protrudes radially outwardly relative to the housing sections 802, 804. As with the detector cable 800 of FIG. 13, the housing sections 802, 804 may be welded to the detector support housing 806A to provide the seal coupling. Alternatively, other forms of sealing engagement or adhesion may be employed. The enlarged diameter or width of the detector support housing 806A allows a cavity 824 to be defined in the detector support housing 806A. The cavity 824 can be used to receive a pressure and temperature sensing element 826, which can be used to detect both pressure and temperature (or only one of pressure and temperature) or any other type of detectors. An external surface 828 of the sensing element 826 is exposed to the external environment outside of the 800A cable of detectors. The sensing element 826 is sealingly connected to the detector support housing 806A by means of the connections 830, which may be welded connections or other types of sealing connections. The cables 832 connect the sensing element 826 to the detector 808a contained in the detector holder 810 within the detector support housing 806A. The cables 832 connect the sensing element 826 with the integrated detection circuit 812 of the detector 808A, which integrated circuit 812 of the detector is capable of detecting pressure and temperature based on the signals of the sensing element 826. Fig. 15 shows a sensor cable 800 which is implemented on a reel 840. As shown in Fig. 15, the detector cable 800 includes the cartridge 116 of the controller and a detector 114. The additional detectors 114 which are part of the detector cable 800 are wound on the reel 840. To implement the sensor cable 800, the detector cable 800 is unwound to a desired length (and a number of detectors 114) has been unwound, and the sensor cable 800 can be unwound. be cut and connected to a completion system.

Fig. 16 shows an alternative embodiment of a detector cable 900, which is comprised of a control line 902 (which can be formed of a metal such as steel, for example). Note that the control line 902 is a continuous control line that includes several detectors. The control line 902 has an internal hole 904 in which the detectors 906 are provided, where the detectors 906 are interconnected by means of electrical cables 908. According to some embodiments, the internal orifice 904 of the control line 902 is filled with a liquid that does not conduct electricity to provide efficient heat transfer between the outside of the control line 902 and the detectors. The liquid that does not conduct the electricity (or other fluids) in the inner hole 904 is thermally conductive to provide heat transfer. Also, the fluid in the control line 902 allows the establishment of a temperature average across a certain length of the control line 902, due to the thermal conduction characteristics of the fluid. According to some modalities, the 906 detectors can be implemented with resistance temperature detectors (RTDs). RTDs are thin-film devices that measure temperature based on the correlation between the electrical resistance of the conducting materials electricity and temperature change. In many cases, RTDs are manufactured using platinum, due to the linear resistance-temperature relationship of platinum. However, RTDs made of other materials can be used. Precision RTDs are widely available within the industry, for example, from Heraeus Sensor Technology, Reihard-Heraeus-Ring 23, D-83801 Kleinostheim, Germany. The use of inductive coupling according to some modalities allows a significant variety of detection techniques, not only of temperature measurements. The pressure, the flow, the density of the fluids, the reservoir resistivity, the oil / gas / water ratio, the viscosity, the carbon / oxygen ratio, the acoustic parameters, the detection of chemicals, for example, (slag, paraffin, asphaltenes, deposition, pH detection, salinity detection) and so on, can all receive energy and / or data communication through inductive coupling. It is desirable that the detectors are small in size and have a relatively low energy consumption. Such detectors have recently been available in the industry, such as those described in O 02/0775613. Note that the detectors may be directly measuring a property of the reservoir, or reservoir fluid, or they may be measuring such properties through an indirect mechanism.

For example, in the case that geophones or acoustic detectors are placed along the sand wall and where such detectors measure the acoustic energy generated in the formation, that the energy may come from the release of voltage caused by the billing of the rock formation in a hydraulic billing or near the well. This information in turn is used to determine the mechanical properties of the reservoir, such as the directions of the main stress, as described, for example, in the North American Publication No. 2003/0205376. The uppermost detector 906 shown in Fig. 16 is connected via cables 910 to a splice structure 912, which interconnects the cables 910 to the cables 914 within a control line 915 leading to a controller cartridge ( not shown in Fig. 16). Note that the splice structure 912 is provided to isolate the fluids in the orifice 904 of the control line of a chamber 916 in the control line 915. Fig. 17 illustrates a different arrangement of a detector cable 900A. The detector cable 900A also includes a control line 902 that defines the internal orifice 904 that contains a fluid that does not conduct electricity. However, the difference between the detector cable 900A of Fig. 17 and the detector cable 900 of Fig. 16 is the use of detectors 900A modified in Fig. 17. Detectors 906? they include a filament 920 of RTD cable (which has a resistance that varies with temperature). The filament 920 is connected to an electronic integrated circuit 922 to detect the resistance of the RTD cable filament 920 to allow detection of the temperature. Fig. 18 illustrates yet another arrangement of a detector cable 900B. In this embodiment, the control line 902 does not contain a liquid (rather, the internal orifice 904 of the control line 902 contains air or some other gas). The detector cable 900B includes the detectors 906B having an encapsulation structure 930 for containing a conductive liquid 932 in which the filament cable RTD 920 and the electronic integrated circuit 922 are provided. Fig. 19 shows a cross-sectional view of another embodiment of a completion system including a bypass tube 1002 for transporting the gravel suspension for gravel packing operations. The bypass tube 1002 extends from a location on the land surface to the areas of interest. Two zones 1004 and 1006 are shown in Fig. 19, with packers 1008 and 1010 used for the isolation of the zones. In the first zone 1004, a baffle assembly 1112 is provided around a perforated base tube 1114. As The fluid is allowed to flow from the reservoir in the area 1004 through the baffle assembly 1112 and through the perforations of the perforated tube 1114 into an internal hole 1116 of the completion system shown in FIG. 19. Once that the fluid enters the internal orifice 1116, the fluid flows in the direction indicated by the arrows 1118. The perforated base tube 1114 at its lower end is connected to a blank tube 1120. The lower end of the blank tube 1120 is connected to another perforated base tube 1122 that is placed in the second zone 1006. A bulkhead assembly 1124 is provided around the perforated base tube 1122 to allow fluid to flow out of the zone 1006 adjacent to the reservoir to the flow of fluids in the internal orifice 116 of the completion system through the screen assembly 1124 and the perforated base tube 1122. The perforated base pipes 1114, 1122 and the blank pipe 1120 constitute a production conduit containing the internal hole 116. The bypass tube 1002 is provided in an annular region between the outside of this production conduit and a wall 1126 of the well. In Fig. 19, the wall 1126 is a sand wall. Alternatively, the wall 1126 may be a liner or jacket.

As further depicted in FIG. 19, the detectors 1128, 1139 and 1132 are connected to the branch tube 1002. The detector 1128 is provided in the area 1004 and the detector 1132 is provided in the area 1006. The detectors 1128 and 1132 are placed in radial flow paths of the respective zones 1004 and 1006. On the other hand, the detector 1130 is placed between the packers 1008 and 1110, which are in a non-fluid area of the well (there is no flow of fluids in the radial direction or the longitudinal direction in the space 1134 that is defined between the two packers 1008 and 1110 and between blank tube 1120 and inner wall 1126 of the well). The detectors 1128, 1139, and 1132 are detectors in a detector cable. A transverse view of the bypass tube 1002 and a detector wire 1136 are shown in Fig. 20. The bypass tube 1002 has an internal hole 1138 in which the gravel suspension is flowing when the packaging operations are carried out of gravel. In a gravel packing operation the gravel suspension is pumped into the inner hole 1138 of the bypass tube 1002 to the annular regions in the well that must be packed with gravel. Connected to the branch tube 1002 is a detector clamp 1140 (which usually has a C shape in the implementation and emplificante). The detector cable 1136 is held in place by the clamp clip 1140 of the detector. The clamp clip 1140 of the detector is attached to the bypass tube 1002 by means of one of several mechanisms, such as by welding or by some other type of connection. In an alternative embodiment, the bypass tubes can be omitted and a screen without the bypass tube is used. The gravel is pumped into the annular cavity between the external surface of the screen and the wall of the well. A cable protector adheres to a base tube of the screen between the successive sections of the screen (or the slotted or perforated tube) to protect the detector and the cable. In another embodiment, the detector wire is secured to make contact with a base tube such that the base tube provides both an electrical ground connection for the detector wire and the detectors, and acts as a heat sink to allow the Heat dissipation of the detector cable and detectors in the base tube. Fig. 21 shows an exemplary completion system for use with a multilateral well. In the example of Fig. 21, the multilateral well includes a main section 1502 of the well, a side branch 1054, and a section 1505 of the main well 1502, which extends below the junction of the lateral branch between main well 1502 and lateral branch 1504. As shown in FIG. 21, the main well 1502 is coated with a liner 1506, with a window 1508 formed in the liner 1506 to allow a lateral completeness 1510 to pass to the lateral branch 1504.

A 1512 section of top completion is provided above the splice of the side branch. The upper completion section 1512 includes a production packer 1514. Connected above the production packer 1514 is a production line 1516, to which a control station 1518 is connected. The control station 1518 is connected by means of an electric cable 1520 which passes through the production packer 1514 to an inductive coupler 1522 below the production packer 1514. The completion in the main well and the lateral well are very similar to those in the modality of Fig. 1A. in a variant of the embodiment of Fig. 1A, flow control devices are provided that are controlled remotely. The power and communications from the main well to the side are executed or realized through an inductive coupler 1522.

In turn, the electric cable 1520 (which is part of a lower completion section 1526) also passes through a lower packer 1532. The electric cable 1520 connects the inductive coupler 1522 with the control devices 1528 (e.g., the flow control valves) and the detectors 1530. The lower completion section 1526 also includes a bulkhead assembly 1538 for carrying out sand control. The detectors 1530 are provided adjacent to the sand control assembly 1538. The lower completion may not include the bulkhead in some modes. Depending on the construction and type of the multilateral splice an inductive coupler is placed with the splice. A cable is placed from the inductive coupler of the splice to the valves of the flow control and the detectors in the completion of the splice similar to the mode of Fig. 1A. The cable 1534 of the inductive coupler 1522 is connected to the flow control valve and the detector in the completion in the side section 1054. As part of the lower completion section 1526, another inductive coupler 1531 is provided to allow communication between the electric cable 1520 and an electrical cable of the completion of the main well extending to the 1505 section of the main well to the flow control devices and / or detectors 1528 and 1531 in section 1505 of the main well. Fig. 22 shows another embodiment of the two-stage completion system which is a variant of the embodiment of Fig. 1A. In the embodiment of Fig. 22, flow control devices 1202 (or other types of control devices that can be controlled remotely) are provided with the sand control assembly 110. The flow control devices (or other devices that can be controlled remotely) are connected by means of respective electrical connections 1204 (such as in the form of electric cables) to the detector cable 112. With this implementation, the detector cable 112 is not only capable of providing communication with the detectors 114, but is also capable of allowing a well operative to control the flow control devices (or other devices that can be controlled from remote way) located near a sand control assembly from a remote location, such as the land surface.

The types of flow control devices 1202 that can be used include hydraulic flow control valves (which are energized using an electric pump or an atmospheric chamber that is controlled with power supply and signals from the earth's surface through the control station 146); the electric flow control valves (which are energized by power supply and signaling from the earth's surface through the control station 146); electro-hydraulic valves (which are energized by means of power supply and signaling of the land surface through the control station 146 and the inductive coupler); and alloy valves with register or shape memory (which are energized by means of power supply and signaling of the land surface through the control station and the inductive coupler). With electrical flow control valves, a storage capacitance (in the form of a capacitor) or any other energy storage device can be used to store a load that can be used for the high drive requirements of electrical control valves . The capacitor can be slow and continuous when it is not in use. For electro-hydraulic valves, which employ pistons to control the amount of flow through the electro-hydraulic valves, the signaling circuitry and solenoids can control the amount of fluid distribution within the valve pistons. to enable a large number of shock positions for the control of fluid flow. A shape memory or alloy valve relies on changing the shape of a valve member to cause it to change the valve setting. Signage is applied to change the shape of that element.

Fig. 28 shows yet another embodiment of a completion system that is a variant of the embodiment of Fig. 27 that does not require an intermediate completion (1400B in Fig. 27) to implement the isolation valve of the annular array.

The upper completion section 1460 also includes the flow control assembly 1438 similar to that shown in Fig. 27.

In the various modalities discussed above, several multi-stage completion systems have been discussed that include a higher completion section and a lower completion section and / or the intermediate completion section. In some scenarios, it may not be appropriate to provide a higher completion section after a lower completion section has been installed. This may be because the well is suspended after the lower completion is made. In some cases, the wells in the field are drilled in batches and the lower completions are completed in batches and then suspended and then at a later date the higher completions are completed in batches. Also in some cases it may be desirable to establish a thermal gradient through the formation for the purpose of comparison with the changing temperature or other parameters of the formation before altering the formation to aid in the analysis. In such cases, it may be desirable to take advantage of the detectors that have already been implemented with the lower completion section of the two-stage completion system. To be able to communicate with the detectors that are part of the lower completion section, an intervention tool that has a male portion of the inductive coupler can be lowered into the well such that the male portion of the inductive coupler it can be placed adjacent to a female portion of the inductive coupler that is part of the lower completion section. The inductive coupler portion of the intervention tool interacts with the inductive coupler portion of the lower completion section to form an inductive coupler that allows the measurement data to be received from the detectors that are part of the lower completion section. The measurement data can be received in real time through the use of a communication system of the intervention tool to the surface, or the data can be stored in the memory in the intervention tool and downloaded at a later time. In the case that real-time communication is used, this could be via a connection cable, mud impulse telemetry, fiber optic telemetry, wireless electromagnetic telemetry or other telemetric procedures known in the industry. The intervention tool can be lowered into a cable, articulated pipe. Measurement data can be transmitted during an intervention process to help monitor the status of that intervention. Fig. 29 shows an example of such an arrangement. The lower completion section depicted in Fig. 29 is the same lower completion section of Fig. 2 discussed above. In the arrangement of Fig. 29, the upper completion section has not yet been implemented. Instead, an intervention tool 1500 is lowered into the well on a 1502 carrier line. The intervention tool 1500 has a portion 1504 of inductive coupler that is capable of interacting with the portion 118 of the inductive coupler in the lower completion section 102. The carrier line 1502 may include an electrical cable or an optical fiber cable to allow communication of the data received through the portions 118, 1504 of the inductive coupler to a location on the land surface. Alternatively, the intervention tool 1500 may include a storage device for storing the measurement data collected from the detectors 114 in the lower completion section 102. When the intervention tool 1500 is retrieved later to the earth's surface, the data stored in the storage device can be downloaded. In this last configuration, the intervention tool 1500 can be lowered in a steel line, with the intervention tool that includes a battery or other energy source to provide the power to allow communication through the portions 118, 1504 of the inductive coupler with the detectors 114. A system with intervention base can also be used for the operation of the spiral pipe. During the spiral pipe operation, it can be beneficial to collect the data from the sand wall to help decide which fluids are being pumped into the well through the spiral pipe and at what flow. The measurement data collected by the detectors can be communicated in real time back to the surface by the intervention tool 1500. In another implementation, the intervention tool 1500 may be placed in a drill tube, however, it is difficult to provide an electrical cable along the drill pipe due to the joints of the tube. To address this, electrical cables can be integrated into the drill pipe with coupling devices at each joint provided to obtain a cable drill pipe. Such a drill pipe with cables is capable of transmitting data and also makes possible the transmission of fluids through the pipe. The intervention-based system can also be used to perform drill stem tests collected by the detectors 114, transmitted to the Earth surface during the test to allow the well operator to analyze the transmitted results of the drill stem tests. The lower completion section 102 may also include components that can be manipulated by the intervention tool 1500, such as sliding sleeves that can be opened or closed, packagers that can be fixed, not assembled, and so on. By monitoring the measurement data collected by the detectors 114, a well operator can be provided with a real-time indication of the success of the intervention (for example, the closing or opening of the sliding sleeve, the attachment or disassembly of the packer, etc.). In an alternative implementation, the lower completion section 102 may include several female portions of the inductive coupler. The male portion of the inductive coupler (e.g., 1504 in Fig. 29) can then be lowered into the well to allow communication with any female portion of the inductive coupler to which the male portion of the inductive coupler is placed. Note that the intervention tool 1500 shown in Fig. 29 can also be used in a multilateral well having multiple lateral branches. For example, if one of the side branches is producing water, the intervention tool 1500 can be used to enter the lateral branch with spiral pipe to allow the pumping of a flow inhibitor in the lateral branch to stop the production of water. Note that surface measurements would not be able to indicate which lateral branch was producing water; only downhole measurements can carry out this detection. Each of the branches of the multilateral well can be equipped with a measurement arrangement and an inductive coupler portion. In such an arrangement, there would be no need for a permanent power source in each lateral branch. During the intervention, the intervention tool can access a particular lateral branch to collect the data of that lateral branch, which would provide information on the flow properties of the lateral branch. In some implementations, the detectors or the controller cartridge associated with the detectors in each side branch may be provided with an identification tag or other identifier, such that the intervention tool will be able to determine which lateral branch the operator has entered. intervention tool.

Note also that labels within the measurement system can change the properties based on the results of the measurement system (for example, changing a signal if the measurement system detects significant water production). The intervention tool can be programmed to detect a particular label, and to enter a lateral branch associated with that particular label. This would simplify the task of knowing which lateral branch to enter to address a particular problem. Although the invention has been described with respect to a limited number of embodiments, those skilled in the art who have the benefit of this disclosure will appreciate the numerous modifications and variations thereof. It is intended that the appended claims cover such modifications and variations when they fall within the true spirit and scope of the invention.
