Definitions
- the present invention generally relates to control and actuation of downhole tools.
- Completion is the general process of bringing a well into production after drilling into a subterranean formation having a hydrocarbon reservoir.
- a single well may be completed multiple times, creating multiple "zones" for fluids to communicate between the reservoir and the wellbore.
- the zone When completing a given zone, the zone may need to be isolated from other zones. For example, when a zone is to be hydraulically fractured, the zone may need to be isolated from uncompleted zones to prevent their premature fracturing and from previously completed zones to prevent fluid losses into the formation.
- Zones are generally isolated by downhole tools.
- Downhole tools may include packers for sealing zones, sliding sleeves operable to permit flow to and from specific zones, control valves for controlling and directing flow, and various other tools for performing other functions.
- the downhole tools may be operable between different positions or modes of operation.
- Some downhole tools are operated in part by onboard electronics that receive control signals from operators at the surface. In response to the control signals, the electronic controls can operate the downhole tool in more complicated ways than are typically possible using hydro- mechanical control alone. However, because of the distance between the surface and the downhole tools, interference created by the formation, generally harsh downhole conditions, and various other factors, communication between the surface and the downhole tools may be difficult. As a result, a reliable means for communicating with downhole tools is desirable.
- FIG. 1 is a schematic of a well system following a multiple-zone completion operation
- FIG. 2 is a block diagram depicting an embodiment of onboard electronics, actuators and other electronic components of a downhole tool.
- FIG. 3 is a series of graphs representing different embodiments of magnetic signals.
- FIG. 4 is a schematic view of an embodiment of a magnetic source tool.
- FIG. 5 is a schematic view of another embodiment of a magnetic source tool.
- FIGS. 6A-C are schematic views of an embodiment using magnetic balls for signaling the downhole tool.
- FIG. 1 is a schematic of a well system following a multiple-zone completion operation.
- a wellbore extends from a surface and through subsurface formations.
- the wellbore has a substantially vertical section 104 and a substantially horizontal section 106, the vertical section 104 and horizontal section 106 being connected by a bend 108.
- the horizontal section 106 extends through a hydrocarbon bearing formation.
- One or more casing strings 110 are inserted and cemented into the vertical section 104 to prevent formation fluids from entering the wellbore.
- the well system depicted in FIG. 1 is generally known as an open hole well because the casing strings 1 10 do not extend through the bend 108 and horizontal section 106 of the wellbore. As a result, the bend 108 and horizontal section 106 of the wellbore are "open" to the formation.
- the well system may be a closed hole type in which one or more casing strings are inserted in the bend 108 and the horizontal section 106 and cemented in place.
- the embodiment in FIG. 1 includes a top production packer 1 12 disposed in the vertical section 104 of the wellbore that seals against the innermost casing string.
- Production tubing 1 14 extends from the production packer 1 12, along the bend 108 and extends along the horizontal section 106 of the wellbore.
- Disposed along the production tubing 114 are various downhole tools including packers 116A-E and sleeves 118A-F.
- the packers 116A-E engage the inner surface of the horizontal section 106, dividing the horizontal section 106 into a series of production zones 120 A-F.
- Each of the sleeves 1 18A-F is generally operable between an open position and a closed position such that in the open position, the sleeves 1 18 A-F allow communication of fluid between the production tubing 1 14 and the production zones 120A-F.
- fluid communication is generally from the formation, through the open sleeves, and into the production tubing.
- the packers 116 A-F and the top production packer 112 seal the wellbore such that any fluid that enters the wellbore below the production packer 1 12 is directed through the sleeves 1 18 A-F, the production tubing 1 14, and the top production packer 112 and into the vertical section 104 of the wellbore.
- Hydraulic fracturing is a method of stimulating production of a well and generally involves pumping specialized fracturing fluids down the well and into the formation. As fluid pressure is increased, the fracturing fluid creates cracks and fractures in the formation and causes them to propagate through the formation. As a result, the fracturing creates additional communication paths between the wellbore and the formation.
- Isolating the zone being fractured may require actuating one or more downhole tools between different configurations, positions, or modes. For example, isolating the zone may require a sliding sleeve tool to move between a closed configuration and an open configuration, a packer may need to engage or disengage the wellbore, or a control valve may need to change its configuration to redirect the fracturing fluid.
- a downhole tool may include onboard electronics and one or more actuators to facilitate operation of the downhole tool.
- FIG. 2 is a block diagram depicting a configuration of onboard electronics, actuators and other electronic components of a downhole tool.
- the onboard electronics 202 may include a controller 204 for storing and executing instructions.
- the controller 204 includes a processor 206 for executing instructions and a memory 208 for storing instructions to be executed by the processor 206 and may further include one or more input/output (I/O) modules 209 for communication between the controller 204 and other electronic components of the downhole tool.
- I/O input/output
- the controller 204 communicates with one or more actuators 210 to operate the downhole tool between configurations, positions, or modes.
- the actuators 210 convert electrical energy from a power source 212 to move one or more downhole tool components.
- one actuator may be a linear actuator that retracts or extends a pin for permitting or restricting movement of a downhole tool component.
- Another actuator may rotate a valve body to redirect a fluid flow through the downhole tool.
- the onboard electronics 202 and actuators 210 may be connected to a power source 212.
- the power source 214 may be a battery integrated with the downhole tool or integrated with another downhole tool electrically connected to the downhole tool.
- the power source 212 may also be a downhole generator incorporated into the downhole tool or as part of other downhole equipment.
- the power source may be located at the surface and may
- the downhole tool may include at least one sensor 216 for detecting a physical property and converting the property into an electrical signal.
- the sensor 216 communicates the electrical signal to the onboard electronics 202.
- the controller 204 may execute instructions based on the electrical signal.
- One or more of the instructions executed by the controller 204 may include sending signals to one or more of the actuators 210, causing the actuators to actuate.
- the senor 216 is a magnetic sensor.
- the magnetic sensor may be a Hall Effect or similar sensor that detects magnetic field strength.
- the magnetic sensor may be a magnetometer or similar sensor that detects magnetic field direction and strength.
- the sensor 216 converts magnetic signals into electrical signals that reflect characteristics of the magnetic signals. As a result, different magnetic signals may be used to generate different electrical signals. Because the onboard electronics 202 execute instructions based on electrical signals from the sensor 216, different magnetic signals may be used to cause the controller to execute different instructions and to perform different functions of the downhole tool. For example, in one embodiment, one magnetic signal may cause the controller 204 to execute an instruction issuing a command to an actuator to move in a first direction, while a second magnetic signal may cause the controller 204 to issue a command to the actuator to move in a second direction. In another embodiment, the second magnetic signal may cause the onboard electronics to enter into a "sleep" mode in which the onboard electronics do not respond to magnetic signals other than a specific signal to "awaken" the onboard electronics.
- FIGS. 3A-D are graphs depicting magnetic fields over time for illustrating different magnetic signals.
- the magnetic signals in FIGS. 3A-D are merely illustrative and do not limit the appropriate types of magnetic signals.
- a magnetic signal is any magnetic field or change in a magnetic field that is converted to an electrical signal by the downhole tool sensor, the electrical signal causing the controller to execute one or more instructions.
- Magnetic signals are differentiated by detectable characteristics of the magnetic signal.
- a detectable characteristic may be any characteristic of a magnetic signal that may be detected by the magnetic sensor, captured in the electrical signal generated by the magnetic sensor, and recognized by the onboard electronics 202.
- FIG. 3A is a graph illustrating magnetic signals in which the detectable characteristic is based on a series of magnetic pulses.
- the onboard electronics may be configured to execute instructions in response to different quantities or patterns of magnetic pulses.
- the onboard electronics may respond to a total quantity of pulses, a specific number of pulses within a period of time, a delay between pulses, a specific pattern of pulses and delays, or any similar signal.
- Several possible magnetic signals may be represented by the pulses depicted in FIG. 3A.
- magnetic signals in FIG. 3A may include a total of five pulses, three quick pulses in quick succession, or a delay, followed by three quick pulses.
- FIG. 3B is a graph illustrating magnetic signals in which the detectable characteristic is the frequency.
- the onboard electronics may be configured to execute instructions in response to a specific frequency of a magnetic field, a specific change in frequency of a magnetic field, a pattern of frequencies of a magnetic field, or any similar measureable characteristic of the frequency of a magnetic field.
- Several magnetic signals may be represented by the sinusoidal magnetic field depicted in FIG. 3B. For example, one signal may be the higher frequency sinusoid in the middle of the graph.
- FIG. 3C is a graph illustrating magnetic signals in which the detectable characteristic is the field strength.
- the onboard electronics may be configured to execute instructions in response to a magnetic field being above a threshold strength, being within a range of strengths, undergoing a change in strength, or any pattern of field strengths or changes in field strength.
- FIG. 3D is a graph that illustrating magnetic signals in which the detectable characteristic is the duration or dwell time of a magnetic field.
- the onboard electronics may be configured to execute instructions in response to a magnetic field being present for a particular period of time, being absent for a particular period of time, or any pattern of being present and absent.
- the two or more magnetic signals may or may not be of the same types of signal.
- a first magnetic signal may be based on frequency, while a second magnetic signal may be based on a series of magnetic pulses.
- a first magnetic signal may be based on a first frequency, while a second magnetic signal may be based on a second, different frequency.
- the onboard electronics may also take into account an order in which the magnetic signals are received by the onboard electronics. For example, the onboard electronics may respond to a magnetic signal based on magnetic field but only after first detecting another magnetic signal based on a series of magnetic pulses.
- At least one magnetic source may be used to generate the magnetic signals.
- the magnetic source may include at least one magnet.
- the magnet may be a permanent magnet or an electromagnet.
- FIG. 4 is a schematic view of a magnetic source tool in accordance with one embodiment.
- the magnetic source tool 400 includes multiple permanent magnets 402A-C disposed on a central body 404. As depicted in FIG. 4, the magnetic source tool 400 may be lowered into a wellbore by a wireline 406 or similar line such as a coiled cable. The magnetic source tool may be lowered into the wellbore under the force of gravity or may be pumped down the wellbore.
- FIG. 4 also includes a downhole tool 408 with a sensor 410 for detecting magnetic signals generated by the magnetic source tool 400.
- Different magnetic signals with different detectable characteristics may be achieved by altering the quantity, positioning, and strength of the permanent magnets 402A-C, or by changing the manner in which the magnetic source tool 400 is inserted into the wellbore.
- one magnetic signal consisting of a series of three pulses may be generated by moving the magnetic source tool 400 past the sensor 410, each pulse being generated as each of the permanent magnets 402A-C passes the sensor 410.
- the magnetic source tool 400 may also be used to generate a second magnetic signal based on dwell time by positioning the magnetic source tool 400 such that one of the permanent magnets 402A-C is maintained in close proximity to the sensor 410.
- FIG. 5 is a schematic view of another embodiment in which the magnetic source tool includes an electromagnet 502.
- FIG. 5 also includes a downhole tool 508 having a sensor 510 for detecting magnetic signals generated by the electromagnet 502.
- the electromagnet 502 is supplied with power by a power source via an electrical line 504.
- the magnetic source tool may include an onboard power source such as a battery.
- the power source is connected to the electromagnet such that when the power source is activated, current flows to the electromagnet and the electromagnet generates a magnetic field.
- a wireline 506 may be attached to the electromagnet 502.
- the electrical line 504 and the wireline 506 may be separate lines, as depicted, or may be integrated into a single cable.
- the electromagnet 502 generates a magnetic field when it receives electrical power from the power supply.
- the electromagnet may produce various magnetic fields and various magnetic signals.
- the frequency or waveform of the power supplied to the electromagnet may be changed to create different magnetic fields and magnetic signals with changes in frequency or waveform corresponding to those of the power supplied.
- power electronics may be incorporated directly into the power source or otherwise included in a broader power system.
- a magnetic source is one or more magnetic balls.
- the magnetic balls are designed such that they may be dropped into or shot into the wellbore by a ball launcher.
- the downhole tool sensors detect the magnetic fields of the magnetic balls as the magnetic balls move through the wellbore and past the downhole tool.
- the quantity of magnetic balls, frequency at which the magnetic balls are introduced, and the magnetic strength of the magnetic balls may be varied to produce different magnetic signals.
- FIG. 6A depicts a portion of a horizontal wellbore having production tubing on which a series of downhole tools are disposed.
- the downhole tools include four packers 604A-D and three sliding sleeve tools 606 A-C.
- FIGS. 6B and 6C are each detailed views of sliding sleeve tool 606 A.
- FIG. 6B depicts the sliding sleeve tool 606A in a closed position while FIG. 6C depicts the sliding sleeve tool 606A in an open position. Because the sliding sleeve tools 606A-C are substantially the same, the description of the structure and operation of sliding sleeve tool 606A, below, generally applies to the other sliding sleeve tools 606B-C.
- sliding sleeve tool 606 A includes an actuator 614 and onboard electronics 608, which further include a sensor 609.
- the sliding sleeve tool 606A further includes a collapsible baffle 615.
- the baffle 615 is configured to collapse when fluid is introduced into a chamber 616 behind the baffle 615.
- the actuator 614 selectively opens and closes a port 618 through which fluid may enter the chamber 616.
- the sliding sleeve tool 606A includes a series of communication ports 620 around its circumference.
- the communication ports 620 allow fluid to flow between the production tubing and the formation when the sliding sleeve tool is in the open position as depicted in FIG. 6C.
- a ball 624 is dropped or launched into the wellbore. If the baffles 615 are in the open position, the ball 624 simply passes through the sliding sleeve tool 606 A and further down the wellbore. However, if the baffle 615 is collapsed, the ball is caught by and seals against the baffle 615.
- the ball prevents the fluid from flowing through the sliding sleeve tool. This causes hydraulic pressure to build behind the ball, exerting a force on the ball and baffle. As the pressure continues to build, the force eventually becomes sufficient to slide the sleeve 622 to its open position, exposing the ports 620.
- the balls are magnetic and have a magnetic field.
- the sensor 609 detects the magnetic field of the passing magnetic ball as a magnetic pulse and transmits a corresponding electronic signal to the onboard electronics 608.
- Each sliding sleeve tool is configured to collapse its respective baffle after a certain number of balls have passed, that is, after the onboard electronics receive a certain number of electronic signals from the sensor 609 generated by the sensor 609 in response to passing magnetic balls.
- the furthest downhole sleeve 606C may begin with its baffie in a collapsed position to catch and be opened by a first magnetic ball.
- the onboard electronics of sliding sleeve tools 606A and 606B register a first magnetic pulse.
- the onboard electronics of sliding sleeve tool 606B may be configured to collapse the baffle of sliding sleeve tool 606B when the onboard electronics register a single magnetic pulse via the sensor 609.
- the baffle of the sliding sleeve tool 606B would collapse, permitting the sliding sleeve tool 606B to catch and be opened by a second magnetic ball introduced into the wellbore.
- the onboard electronics of sliding sleeve tool 606A would register a second magnetic pulse.
- the onboard electronics of sliding sleeve tool 606A may be configured to collapse the baffle of sliding sleeve tool 606A when the onboard electronics detect a magnetic signal consisting of two magnetic pulses. As a result, after detecting the second pulse generated by the second magnetic ball, the baffle of the sliding sleeve tool 606A would collapse, permitting the sliding sleeve tool 606 A to catch and be opened by a third magnetic ball.
- the sliding sleeve tools 606A-C can be sequentially opened by introducing magnetic balls. This permits sequential completion of production zones adjacent to each sliding sleeve tool.
- fracturing of a particular formation zone is carried out but found to be insufficient, it may be necessary to survey the zone being fractured before moving on to another zone.
- Some survey tools survey the formation using a high powered magnetic field. Such a field could cause the onboard electronics of the sliding sleeve tools to detect false pulses and to actuate out of sequence.
- a magnetic retrieval tool may be used to retrieve the equipment from the wellbore. Similar to the survey tool, the magnetic field of the magnetic retrieval tool may cause the sliding sleeve tools to detect false pulses and to actuate out of sequence.
- the sliding sleeve tools overcome the above problems by being configured to actuate in multiple ways in response to multiple magnetic signals. As a result, several options exist to ensure that the sliding sleeve tools 606A, 606B and 606C are either not actuated out of sequence or can be reset if they are.
- the sliding sleeve tools may be configured to respond to a second magnetic signal that toggles the sliding sleeve tool into and out of a "sleep" mode.
- a second magnetic signal that toggles the sliding sleeve tool into and out of a "sleep" mode.
- all functions of the sliding sleeve tool including counting magnetic pulses, are suspended until the second magnetic signal is used to "wake” the sliding sleeve tool.
- a magnetic source tool as described earlier in this disclosure, may be introduced into the wellbore and used to produce the second magnetic signal.
- the sliding sleeve tools could respond to a second magnetic signal by resetting themselves.
- the resetting could be a mechanical resetting of the baffle.
- the second magnetic signal could be used to cause an actuator open a relief port that relieves fluid pressure within the chamber 616 and returns the baffle its expanded position.
- the resetting could be a resetting of the logic within the onboard electronics. Specifically, the second magnetic signal may be used to reset the count of magnetic pulses for one or more of the sliding sleeve tools.
