RECOVERY TOOLS

BACKGROUND OF THE INVENTION Field of the Invention

[0001] Embodiments of the present invention generally relate to hydrocarbon recovery and, more particularly, to techniques and apparatus for updating a screen content and/or control scheme of a remote controller for controlling hydrocarbon recovery tools.

Description of the Related Art

[0002] Drilling tools, such as tongs, overdrive systems, elevators, positioning systems, mud buckets, and other tools used in oilfield operations, can be controlled by dedicated remote control panels or universal remote control panels. These control panels can be located, for example, in a rig control cabin or in locations accessible by equipment operators in control of a particular tool. Whether located in a control cabin or in various locations on the rig, the controllers may be connected to the drilling tools via a wired or wireless connection.

[0003] Different types of drilling tools may operate with different parameters. For example, a tongs system— which may be used to make or break drill pipes by torqueing two lengths of pipe together or breaking a connection between two tubulars— may operate using parameters such as an amount of torque to apply and a direction of rotation and may be commanded to clamp or release a tubular. An elevator system, which may raise and lower a drill pipe, may operate using parameters such as a maximum or minimum height and may be commanded to raise or lower a tubular. Mud buckets, which may be positioned to prevent drilling muds from being spilled on rig floors or other walking surfaces, may be operated by moving the bucket to one of a plurality of predetermined locations and may be either opened or closed. Positioning devices may operate using parameters such as a horizontal, vertical, and/or azimuthal deflection from a reference point {e.g., positioning on the x, y, and z axes). [0004] With dedicated remote controllers, a controller may be connected with {e.g., hardwired to) a specific device and be configured to operate only the device to which the controller is connected or otherwise associated with. Multiple controllers may be employed to operate the variety of drilling tools used in well- drilling operations. For example, each tongs may have a dedicated remote controller; an overdrive system may have its own remote controller; another dedicated remote controller may be used for a mud bucket, and so on. The dedicated remote controllers may be associated with one or more tool controllers. Each of these dedicated controllers may be customized to control parameters used for the specific tool. If a new device is added to a rig, an additional dedicated controller is typically added to control the new device.

[0005] Universal remote controllers, such as a universal remote panel, can be used to control a variety of tools using the same type of remote controller. A universal remote controller, for example, can be used to control tongs, overdrive systems, elevators, positioning systems, mud buckets, and other tools that can be used in oilfield drilling and other hydrocarbon recovery operations. If a new tool is added to a rig, the software of both the universal remote controller and the tool controller associated with the new tool is typically updated in order to support the new tool.

DETAILED DESCRIPTION

[0037] Embodiments of the present invention provide techniques and apparatus for controlling a set of tools for hydrocarbon recovery while allowing a remote controller {e.g., a remote control panel) to be updated as a tool or tool functionality is added, removed, or modified without adding additional hardware controllers or manually updating the firmware or software of the remote controller. Updating the remote controller may entail providing updated screen content and/or control schemes for a tool or tool functionality that has been added, removed, or modified, such that an operator can utilize the remote controller to control any of various tools according to the added, removed, or modified tool or tool functionality.

AN EXAMPLE TOOL CONTROL SYSTEM

[0038] FIG. 1 illustrates an example tool control system 100 in accordance with an embodiment of the present invention. Tool control system 100 may include a variety of tools 102, a tool controller 104, and a remote controller 106.

[0039] Tools 102 may include any of various suitable tools for hydrocarbon recovery operations, such as tongs 102a, overdrive systems 102b, elevators, mud buckets, positioning systems, compensators, draw works, top drives, casing making devices, gripping devices, spiders, mud pumps, pickup and laydown tools, interlocks, cement heads, release balls and plugs, control line positioning tools, blowout preventers (BOPs), bails, and the like. Tools 102 may be communicatively coupled to a tool controller 104, and the tool controller may be communicatively coupled to remote controller 106. Tool controller 104 may support bi-directional communications via one or more communications links between tools 102 and tool controller 104, which may allow tool controller 104 to transmit commands to tools 102 or receive information from the tools. For example, commands transmitted from tool controller 104 to a tool 102 may change an operating parameter of the tool, cause the tool to start or stop performing a function, or instruct the tool to transmit information {e.g., operating parameters or sensor information) to tool controller 104.

[0040] A bi-directional communications link may also be supported between tool controller 104 and remote controller 106. The bi-directional communications link may allow tool controller 104 to transmit information {e.g., device operating parameters from a tool 102) for display on remote controller 106. This may also allow remote controller 106 to transmit commands to cause tool controller 104 to change the operating parameters of a tool 102 or cause tool 102 to start or stop performing a function. Remote controller 106 may be a hardware remote control device or a control system accessible through a graphical human-machine interface (HMI), such as a web interface or an HMI component of a supervisory control and data acquisition (SCADA) system.

[0041] FIG. 1 B is a block diagram of an example tool control system 100, in accordance with aspects of the present disclosure. As illustrated, hydrocarbon recovery tool control system 100 includes a plurality of tools 102, a device controller 104, and a remote controller 106.

[0042] Remote controller 106 generally includes transceiver 132, input devices 134, processor 136 and display 138. In some embodiments, transceiver 132 may support communications via a wired connection, such as a 1000BASE-T (gigabit Ethernet) connection, a serial connection {e.g., an RS-232 connection), or some other wired connection. In some embodiments, transceiver 132 may be a wireless transceiver and may support communications via a variety of wireless protocols. For example, transceiver 132 may communicate in an 802.1 1 (Wi-Fi) network, an 802.16 (WiMax) network, a Uniform Terrestrial Network Access (UTRA) network {i.e., a network supporting cellular communications using the High Speed Packet Access standard), an Evolved Uniform Terrestrial Network Access (E-UTRA) network {i.e., a network supporting cellular communications using the Long Term Evolution (LTE) or LTE-Advanced standards), or other wireless protocols.

[0043] In some embodiments, remote controller 106 may receive one or more screens from device controller 104 and display the one or more screens on display 138. A user may manipulate one or more input devices 134 to modify data displayed on display 138. The data may generally relate to the operation of one or more tools in a hydrocarbon recovery system. Based on user input from the one or more input devices 134, processor 136 may generate one or more commands and transmit the one or more commands to device controller 104 via transceiver 132.

[0044] Device controller 104 generally includes a transceiver 122, programmable logic computer (PLC) 124, and one or more tool input/output devices 126. In some embodiments, device controller 104 may be a fixed control cabinet located in a control room of a drilling rig. In other embodiments, device controller 104 may be a portable control cabinet.

[0045] Device controller 104 may be communicatively coupled to remote controller 106 via transceiver 122. Transceiver 122 may receive one or more commands from remote controller 106 related to operation of one of the one or more tools 102. Based on the received one or more commands, PLC 124 may generate one or more instructions to cause at least one of the one or more tools to perform an action specified by the one or more commands. After PLC 124 generates the one or more instructions, PLC 124 may output the one or more instructions to one of the tool input/output devices 126 for transmission to the at least one of the one or more tools.

[0046] Device controller 104 may be connected to one or more tools 102 via a variety of tool input/output devices 126. In some cases, tool input/output devices 126 may include a wired electrical or optical data transceiver, such as a 1000BASE-T (gigabit Ethernet) interface or a fiber channel interface. Tool input/output devices 126 may also include wireless transceivers, such as transceivers supporting communications using the 802.1 1 (Wi-Fi), 802.16, UTRA, E-UTRA, or other standards. Instructions transmitted via an electrical or optical connection between device controller 104 and a tool 102 may include communications compliant with an industrial communications protocol, such as PROFIBUS or MODBUS. In some cases, tool input/output devices may include an analog current loop carrying current levels for configuring operation of tool 102. For example, the current loop may be a 4-20 milliamp loop or a 10-50 milliamp loop, where the lowest current corresponds to a minimum value of a parameter and the highest current corresponds to a maximum value of a parameter.

[0047] In some cases, tool input/output devices may include one or more fluid power units in fluid communication with one or more of the one or more of tools 102. The fluid power units may include, for example, hydraulic pumps or pneumatic power units. PLC 124 may be communicatively coupled to the fluid power units (e.g., via an actuator) and may generate one or more instructions to cause the fluid power units to increase or decrease fluid pressure at one of the one or more of tools. For example, for hydraulically or pneumatically driven tools, PLC 124 may generate a first instruction to start operation of the tool by causing a fluid power unit associated with one of the one or more tools 102 to introduce an amount of fluid pressure to the tool. When PLC 124 determines that tool 102 has completed the requested operation, PLC 124 may generate a second instruction to cause the fluid unit to release fluid pressure at the tool.

[0048] In some cases, tools 102 generally include a tool PLC 1 12, tool components 1 14, and tool input/output devices 1 16. Tool components 1 14 and tool input/output devices may be communicatively coupled to tool 102. Tool input/output devices 1 16 may receive one or more instructions to command operation of tool 102. Based on the received one or more instructions, tool PLC 1 12 can cause tool components 1 14 to perform an action [e.g., perform a make or break operation on a tubular string, move a mud bucket, etc.). In some cases, sensors associated with tool components 1 14 may generate data related to a current state of tool 102 and, via tool input/output devices 1 16, transmit the data to device controller 104, where the data may be logged and transmitted to remote controller 106 for display.

[0049] In some cases, as illustrated in FIG. 1 C, tools may be connected to device controller 104 via another tool. For example, tool 102b is connected to tool 102a, which is communicatively connected to device controller 104. Tool 102a may be configured to provide a fluid communication conduit [e.g., a hydraulic or pneumatic pass-through), a power conduit, and/or a data connection to tool 102b. In an aspect, tool 102a may be a top drive, and tool 102b may be a tool connected to the top drive.

[0050] Device controller 104 may generate one or more instructions to command operation of tool 102b, and transmit the instructions to tool 102a. In aspects where the instructions comprise data signals transmitted via an electrical or optical medium, the instructions may indicate the device for which the instructions are intended. Tool PLC 1 12a at tool 102a may read the one or more instructions received from device controller 104 and determine whether or not the instructions are intended for operation of tool 102a. If the instructions are intended for operation of tool 102a, tool PLC 1 12a may take one or more actions to cause tool components 1 14a to perform according to the instructions. If, however, the instructions are intended for operation of tool 102b, tool PLC 1 12a may cause the instructions to be transmitted to tool 102b via a tool I/O device 1 16a {e.g., a data transceiver). At tool 102b, the instructions may be received at a tool I/O device 1 16b and processed by tool PLC 1 12b to determine whether the instruction is intended for operation of tool 102b or for yet another tool connected below tool 102b.

[0051] In some cases, tool I/O devices 1 16 may comprise a fluid communication conduit. Fluid pressure generated by device controller 104 and transmitted to tool 102a may be passed through a tool I/O device 1 16a to tool 102b. Tool 102b may be actuated and controlled solely by the supply of pressurized fluid from device controller 104 and routed through one or more other tools. In some cases, PLC 1 12b may be an optional component of tool 102b.

[0052] In some embodiments, remote controller 106 may be located in a driller's cabin, which may be remote from the rigfloor (i.e., an explosive zone). Device controller 104 may be located away from the rigfloor and packaged in a standard housing or located at the rigfloor and packaged in an explosion-proof housing. Remote controller 106 may be communicatively coupled to device controller 104 via a wired or wireless electrical connection or a fiber connection, as discussed above. Device controller 104 may be connected to one or more tools 102 using electrical, hydraulic, and/or pneumatic connections. In some cases, as described above, some tools may be coupled to other tools and communicatively coupled to device controller 104 through the other tools.

[0053] In some embodiments, remote controller 106 and device controller 104 may be located at the rigfloor. In such a deployment, both device controller 104 and remote controller 106 may be housed in explosion-proof housings. In some cases, device controller 104 and remote controller 106 may be co-located in a same housing. In such a deployment, device controller 104 may communicate electrically with PLCs associated with each of the plurality of tools. Instructions transmitted from device controller 104 to a tool 102 may include instructions to cause a PLC associated with tool 102, for example, to actuate one or more electrical and/or fluid power units to perform a specified action.

EXAMPLE REMOTE PANEL

[0054] FIG. 2 illustrates an example remote control panel 200, in accordance with embodiments of the present invention. Remote control panel 200 may operate as a remote controller 106 and may be a universal remote control panel capable of controlling several tools. Remote control panel 200 may include a display 202, one or more wireless antennas 204, an emergency stop button 206, a first joystick 208 (or other directional controller), a second joystick 210 (or other directional controller), and one or more optional legacy controls 212 {e.g., rotary switches). Display 202 may be configured to display a plurality of parameters and commands for a tool being currently controlled by remote control panel 200. The contents of display 202 may change depending on the type of tool selected. For example, display 202 may present a first plurality of operating parameters and commands if a first tool (e.g., tongs) is selected, a second plurality of operating parameters and commands if a second tool {e.g., an overdrive system) is selected, a third plurality of operating parameters and commands if a third tool {e.g., a mud bucket) is selected, and so on.

[0055] Remote control panel 200 may communicate with one or more tool controllers 104 via one or more wireless antennas 204. As illustrated, remote control panel 200 communicates via two antennas 204 for antenna diversity; however, any number of antennas may be used.

[0056] Emergency stop button 206 may be used to stop one or more tools controlled by remote control panel 200 via one or more tool controllers 104. If emergency stop button 206 is activated, remote control panel 200 may transmit, via wireless antennas 204, one or more commands to tool controller(s) 104 commanding the tool controller(s) 104 to stop a particular tool or all tools controlled by tool controller(s) 104 {e.g., by discontinuing power flow to one or more tools). In this manner, the tool(s) can be quickly shutdown to prevent damage to the tool(s) or injury caused by the tool(s), for example.

[0057] Selection and modification of parameters may be performed using first and second joysticks 208, 210. One or both of first and second joysticks 208, 210 may act as a toggle or selection button to perform an action {e.g., returning a tool to a default position, commanding a tool to start or stop operations, and so on). For example, first joystick 208 may be configured to change parameter values {e.g., by moving the first joystick up or down) or move the focus of inputs from first joystick 208 from one field to another {e.g., by moving the first joystick left or right), while second joystick 210 may be configured to command the performance of one or more hardware actions. The functionality of first and second joysticks 208, 210 may change based on the status of remote control panel 200 {e.g., a powering on state, an error handling state), the tool selected, and the mode in which remote control panel 200 is operating in {e.g., a data mode, where parameters of a tool can be viewed and/or modified, or a control mode, where a tool can be commanded to start or stop operations).

[0058] Remote control panel 200 may optionally have one or more "legacy" device controls 212. As illustrated in FIG. 2, remote control panel 200 has three legacy device controls 212; however, any desired number of legacy device controls 212 may be present on remote control panel 200. Legacy device controls 212 may be used to operate various functions on one or more tools. For example, legacy device controls 212 may be used to open or close tongs, switch tongs or an overdrive controller from make mode {i.e., a mode in which two tubulars are connected to each other) to break mode {i.e., a mode in which two tubulars are disconnected from each other), change control from manual control to automatic control, or other functionality as desired. Legacy device controls 212 may be used in lieu of or in conjunction with display 202 and first and second joysticks 208, 210.

[0059] As an alternative (or a supplement) to remote control panel 200, FIG. 3 illustrates an example human-machine interface (HMI) that may be used to control a plurality of tools, in accordance with embodiments of the present invention. A display device 300 may be used to display HMI 302. Display device 300 may be a smartphone, tablet, a personal digital assistant (PDA), monitor, or any other visual display device as desired and may include one or more network interfaces that may be used to connect to and communicate with one or more tool controllers 104. The display for such a device may be a touchscreen and may accept input through a stylus, touch, proximity of a finger, or a combination thereof. Inputs generated on a touchscreen may be used to interact with data elements presented on HMI 302. For example, display device 300 may utilize a wireless local area network (WLAN) interface {e.g., an IEEE 802.1 1 interface), a cellular network interface {e.g., Long Term Evolution (LTE) or Universal Mobile Telecommunication System (UMTS) interfaces), personal area network (PAN) interfaces, or other network interfaces, as desired.

[0060] HMI 302 may be configured to display a plurality of fields corresponding to the various tools connected with the one or more tool controllers 104. A user can select a device, for example, using a drop-down menu 304 (as illustrated), a graphical representation of the device, or any other manner of selecting a device on a graphical user interface (GUI). After a device is selected, HMI 302 may be populated with one or more parameter fields 306i-306„, which may present parameters or operations of the selected device. Parameter fields 306i-306„ may each have a corresponding value field 308i-308„. Each of the value fields 308 may be an editable text field {e.g., for changing the value of a parameter), a toggle button {e.g., for switching operating modes), or some other suitable graphical field. HMI 302 may further have an emergency stop button 310, which may act similarly to emergency stop button 206 of remote control panel 200.

SYSTEM

[0061] FIG. 4A illustrates a block diagram of a remotely controlled tool system 400A, in accordance with embodiments of the present invention. As illustrated, tool controller 104 may comprise an input-output (I/O) device 404, a transceiver 406, and a programmable logic controller (PLC) 408. I/O device 404, transceiver 406, and PLC 408 may be connected with each other, for example, via a communications bus. For example, I/O device 404, transceiver 406, and PLC 408 may communicate with each other via a communications bus over which messages compliant with the MODBUS protocol, PROFIBUS protocol, or other any other desired communications protocol, may be transmitted.

[0062] Remote controller 106 may be connected with tool controller 104 via a wired or wireless connection with transceiver 406. Transceiver 406 may have one or more antennas and may receive commands from remote controller 106 at the one or more antennas to change parameters of a tool 102 or change the operating state of tool 102. Commands received from remote controller 106 may be routed from transceiver 406 to PLC 408 for processing by PLC 408. For example, PLC 408 may receive a command from remote controller 106 to change the value of a certain parameter for a specified tool 102 to a particular value. To change an operating state of tool 102, PLC 408 may receive a command from remote controller 106 to change the operating state of tool 102 {e.g., to change from a stopped state to a running state). After processing the command to change the operating state of tool 102, PLC 408 may transmit one or more commands, via I/O device 404, to tool 102 to instruct the tool to perform a specified function.

[0063] By way of illustration, if a user issues a command through remote controller 106 to begin making a tubular using tongs, PLC 408 may transmit one or more commands to cause the tongs to grip a first tubular with a first pair of tongs, grip a second tubular with a second pair of tongs, and apply a specified amount of torque to one of the tubulars to make a connection between the first and second tubulars. In another example, if an operator issues a command via remote controller 106 to open a mud bucket, PLC 408 may transmit one or more commands to the mud bucket, thereby causing the mud bucket to open.

EXAMPLE SCREEN CONTENT AND/OR CONTROL SCHEME UPDATING FOR

THE REMOTE CONTROLLER

[0064] According to embodiments of the present invention, the screen content and/or control scheme of a remote controller used to control a set of tools for hydrocarbon recovery may be updated to support modified tool functionality and/or a modified tool set. Updates to the screen content and/or control scheme may be achieved without updating the hardware or firmware of the remote controller.

[0065] FIG. 4B illustrates the tool system of FIG. 4A with the addition of a new tool 402 to the set of tools known to PLC 408. Adding a new tool 402 (or modifying the parameters of an existing tool 102) may entail reprogramming PLC 408 with one or more instructions for operating new tool 402 (or modified existing tool 102). PLC 408 may be reprogrammed by an external device 410 {e.g., a laptop computer) transmitting a PLC update package 412 {e.g., with new information) to PLC 408. PLC update package 412 may allow for a whole or partial overwriting of the existing code stored on PLC 408. That is, PLC update package 412 may comprise the entire set of code used by PLC 408 to operate tool system 400B or comprise instructions to overwrite and/or add code for specific methods directed to modified and/or added functionality. Reprogramming PLC 408 to support the new or modified tool may further entail setting one or more data points indicating that PLC 408 has been reprogrammed, modifying {e.g., adding, deleting, or changing) one or more functions to support the new tool 402 or modified existing tool 102, and modifying information about one or more display screens corresponding to new tool 402 or modified existing tool 102.

[0066] Reprogramming PLC 408 may entail stopping operations at PLC 408 before updating one or more functions stored in PLC 408. For example, PLC 408 may be placed in a "programming" mode, which may entail shutting down communication links between PLC 408 and any connected devices {e.g., transceiver 406 and/or I/O device 404). Shutting down communication links between transceiver 406 and PLC 408 may cause remote controller 106 to be disconnected from PLC 408, for example, by causing remote controller 106 to place communication interfaces in an inactive or powered-down state, or by shutting down remote controller 106 in its entirety.

[0067] After external reprogramming of PLC 408 is completed, PLC 408 may exit from "programming" mode (e.g., be switched to "run" mode) and resume communications with tools 102, new tool 402, and remote controller 106 through I/O device 404 and/or transceiver 406. Resumption of communications between remote controller 106 and PLC 408 may entail powering on remote controller 106 (or activating one or more previously inactivated communication interfaces) and reestablishing a connection between remote controller 106 and PLC 408 via transceiver 406, for example.

[0068] A user can select a tool {e.g. , tool 102 or new tool 402) on using one or more input devices (e.g. , first or second joysticks 208, 210, or legacy device controls 212). Remote controller 106 may transmit information related to the tool selection to transceiver 406, which may then transmit that information to PLC 408. PLC 408 may process the selected tool information and transmit screen content and control scheme message 414 to remote controller 106 via transceiver 406. Screen content and control scheme message 414 may be unique to each tool and may include information, for example, defining adjustable operating parameters {e.g., upper and lower bounds for numerical parameters) for the selected tool and control schemes for input devices of the remote panel (i.e. correlations between inputs from an input device and actions that may be performed).

[0069] For example, a screen content and control scheme message for tongs may include information about a minimum and maximum amount of torque that can be applied to two tubulars, units of measurement, and a mapping (i.e., a control scheme) for the input devices. As an example for tongs, the mapping can inform remote controller 106 that up/down movements by first joystick 208 can change the parameter to be adjusted, left/right movements by first joystick 208 can change the value of the selected parameter, and that pushing second joystick 210 into remote controller 106 can activate the tool. As another example for a mud bucket, the mapping can inform remote controller 106 that up/down movements by first joystick 208 can change the parameter to be adjusted, left/right movements by first joystick 208 can change the state or position of the mud bucket; and that pushing second joystick 210 into remote controller 106 can activate the selected state or cause the mud bucket to be moved to the selected position. [0070] After remote controller 106 receives screen content and control scheme message 414, an operator may control existing tools 102 and/or new tools 402 via one or more commands transmitted from remote controller 106 to PLC 408 via transceiver 406.

[0071] FIG. 5 illustrates a flow diagram of example operations 500 that may be performed to communicate between remote controller 106 and PLC 408, in accordance with embodiments of the present invention. At 502, remote controller 106 may receive an input from an operator {e.g., via first or second joystick 208, 210 or legacy device controls 212 of remote control panel 200, or via one or more data inputs from HMI 302). At 504, remote controller 106 transfers the input (or an indication thereof) to transceiver 406. At 506, transceiver 406 writes the information received from remote controller 106 to PLC 408. At 508, PLC 408 reads the information. At 510, PLC 408 updates a screen content (e.g. a screen content for remote controller 106 stored in a memory of the PLC) based on the information. At 512, PLC 408 sends the updated screen content to transceiver 406. At 514, transceiver 406 transfers {e.g., wirelessly transmits) the updated screen content to remote controller 106. At 516, remote controller 106 displays the updated screen content {e.g., on screen 202 of remote control panel 200 or HMI 302). Operations 500 may be continually repeated {e.g., operated in a loop).

[0072] FIGs. 6A-6C illustrate examples of screens that may be displayed to a user {e.g. via display 202 on remote control panel 200 or via HMI 302 on display device 300), in accordance with embodiments of the present invention. A user may be presented, for example, with screen 600 of FIG. 6A, which may show a first command or parameter selected. A user may select the parameter {e.g., via first joystick 208 or second joystick 210 of remote control panel 200 or by selecting a value field 308 in HMI 302). The selected parameter may be modified by the user {e.g., via one or more of joysticks 208 or 210 of remote control panel 200, or by modifying the value in one or more value fields 308 in HMI 302). A user may also change the selected tool, for example, by changing the selected parameter to the tool selection parameter displayed in screen 610 of FIG. 6B and changing the tool displayed on the screen {e.g., via one or more of joysticks 208 or 210 of remote control panel 200) or by selecting a tool via tool selector 304 in HMI 302. As illustrated in the screen 620 of FIG. 6C, the selected tool has been changed from Tongs 30-100 as shown in screen 610 to Tongs 10-145.

[0073] FIG. 7 illustrates example operations 700 that may be performed by a control device, such as tool controller 104 or PLC 408, to support remote control of a set of tools for hydrocarbon recovery and updating screen content and/or control schemes of a remote interface {e.g., a remote panel) without adding hardware or manually updating the remote interface, in accordance with embodiments of the present invention. Operations 700 may begin at 702, with the control device receiving, from a remote interface associated with the control device, a first signal. At 704, the control device alters a screen content for the remote interface to display based on the first signal. At 706, the control device sends to the remote interface a second signal with a representation of the altered screen content. At 708, the control device receives new information for at least one of an existing tool in the set of tools and a new tool {e.g., a new tool recently added to the set of tools). At 710, the control device updates the screen content based on the new information. At 712, the control device sends, to the remote interface, a third signal with a representation of the updated screen content for the remote interface to display.

[0074] For some embodiments, operations 700 may further include storing an initial screen content at the control device for the remote interface to display before altering the screen content based on the first signal at 704

[0075] For some embodiments, operations 700 may further entail sending a control signal from the control panel to the existing tool based on the first signal.

[0076] For some embodiments, operations 700 may further involve receiving, at the control device from the remote interface, a fourth signal based on the updated screen content. Based on the fourth signal, a control signal may be sent from the control device to the existing tool or new tool. For some embodiments, the updated screen content may comprise a new feature {e.g., a new parameter field). The first signal may be based on a control input at the remote interface, and the fourth signal may be based on the same control input to use the new feature. The control input may comprise a directional motion of a joystick, a position of a rotary control, a state of a switch, or a depression of a button.

[0077] For some embodiments, the updated screen content may include a new menu screen for the new tool.

[0078] For some embodiments, the new information may be received at the control device from a computer via a direct wired connection, a wide area network (WAN), or a wireless medium.

The tongs may be tubing tongs, casing tongs, riser tongs, or drill-pipe tongs, for example.

[0081] For some embodiments, the remote interface may be a wireless remote panel, and sending the third signal may entail wirelessly transmitting the third signal to the wireless remote panel via a transceiver connected with the control device.

[0082] FIG. 8 illustrates operations 800 that may be performed, for example, by a control device, such as tool controller 104 or PLC 408, to control tools at a work location, in accordance with embodiments of the present invention. Operations 800 may begin at 802, where the control device transmits a first signal representative of a menu of options to a remote interface. At 804, the control device receives from the remote interface a second signal representative of a selection from the menu of options. The selection may represent a selection of a first tool in the set of tools. At 806, the control device receives a third signal representative of a first operation command. At 808, the control device transmits a fourth signal representative of the first operation command to the first tool. The fourth signal may cause the first tool to operate. At 810, the control device receives from the remote interface a fifth signal representative of a selection from the menu of options. The selection may represent a selection of a second tool in the set of tools. At 812, the control device receives from the remote interface a sixth signal representative of a second operation command. At 814, the control device transmits a seventh signal representative of the second operation command to the second tool. The seventh signal may cause the second tool to operate.

At 904, the control device receives, from the remote interface, a second signal representative of a first selection from the first menu of options. The selection may represent a choosing of a first tool from a set of tools. At 906, the control device transmits a third signal representative of a second menu of options to the remote interface. The second menu of options may, for example, represent operation commands for the first tool. At 908, the control device receives a fourth signal representative of a first operation command from the remote interface. At 910, the control device transmits a fifth signal representative of the first operation command to the first tool, which may cause the first tool to operate. At 912, the control device receives, from the remote interface, a sixth signal representative of a second selection from the first menu of operations. The second selection may represent, for example, a choosing of a second tool out of the set of tools. At 914, the control device transmits a seventh signal to the remote interface. The seventh signal may be representative of a third menu of options, which may represent operation commands for the second tool. At 916, the control device receives an eighth signal representative of the second operation command from the remote interface. At 918, the control device transmits, to the second tool, a ninth signal representative of the second operation command, thereby causing the second tool to operate.
