Abstract

A drilling area network hub is located proximate to a drill rig and includes an uphole transceiver in bidirectional communication with a downhole transceiver by utilizing the drill string as an electrical conductor. Certain information is collected including rig-based and/or location information. At least one field report is generated based on the certain information to characterize at least one of an inground operation, an operational condition of the downhole transceiver, an operational condition of the uphole transceiver, and an operational condition of the drill rig. A drilling area network server receives the field report from the Internet at a remote location and can generate a custom report and/or recommended actions based on field data. Region specific parameters can be applied to the operation of a drilling system. The drilling area network hub can transfer data logs to the remote location according to assigned priorities.

Claims

1. An apparatus for customizing a telemetry system of a horizontal directional drilling system based on region specific parameters, said horizontal directional drilling system including a drill rig and an inground tool that is movable by the drill rig along an underground borepath, said apparatus comprising:

a portable locator for monitoring the position and/or orientation of the inground tool on the borepath and configured at least to transmit a telemetry signal;

a geographic database that provides the region specific parameters for the telemetry signal;

an arrangement for correlating a current location of the system with the geographic database to identify at least one local requirement for the telemetry signal; and

a controller for setting the telemetry signal to conform to the local requirement.

2. The apparatus of claim 1 wherein the region specific parameters include the local requirement as at least one of a maximum transmission power and at least one transmission frequency for said telemetry signal at the current location and the controller sets at least one of a transmit power and a transmit frequency of the telemetry signal to conform to the maximum transmission power and the transmission frequency.

3. An apparatus for use with a horizontal directional drilling system including a drill rig and a subsystem for monitoring the location of an inground tool along an underground borepath, said inground tool configured for transmitting a locating signal through the ground for above ground reception, said apparatus comprising:

a geographic database that provides region specific parameters for the locating signal based on location;

an arrangement for correlating a current location of the system with the geographic database to identify at least one local requirement for the locating signal at the current location; and

a controller for setting the locating signal to conform to the local requirement.

4. The apparatus of claim 3 wherein the region specific parameters include the local requirement as at least one of a maximum transmission power and at least one transmission frequency for the telemetry signal at the current location and the controller sets at least one of a transmit power and a transmit frequency of the locating signal to conform to the maximum transmission power and the transmission frequency.

5. The apparatus of claim 3 wherein said geographic database includes a set of region profiles.

6. An apparatus for customizing a telemetry signal in a horizontal directional drilling system including a drill rig and an inground tool that is movable by the drill rig along an underground borepath, said apparatus comprising:

a telemetry transceiver that is in data communication with said drill rig and configured at least to transmit the telemetry signal;

a geographic database of region specific parameters that specifies at least one local requirement based on location for the telemetry signal;

an arrangement for identifying a current location of the horizontal directional drilling system and for correlating the current location with said geographic database to identify the local requirement for the telemetry signal at the current location; and

a controller for setting at least the telemetry signal to conform to the local requirement.

7. The apparatus of claim 6 wherein the local requirement specifies at least one of a maximum transmission power and at least one transmission frequency for the telemetry signal and the controller is configured to set at least one of a transmit power and a transmit frequency of the telemetry signal to conform to the maximum transmission power and the transmission frequency.

8. An apparatus for customizing a horizontal directional drilling system based on region specific parameters, said system including a drill rig and a subsystem for monitoring the location of an inground tool along an underground borepath, said apparatus comprising:

a geographic database of region specific parameters that specifies location based operational parameters for the horizontal directional drilling system;

an arrangement for identifying a current location of the system and for correlating the current location with said geographic database to identify at least one local requirement for the current location; and

a controller configured to compare the local requirement for the current location to a current operational mode of the system and to issue a notification responsive to a difference therebetween.

9. An apparatus for customizing a horizontal directional drilling system based on region specific parameters, said system including a drill rig and a subsystem for monitoring the location of an inground tool along an underground borepath, said apparatus comprising:

a geographic database of region specific parameters that specifies location based operational parameters for the horizontal directional drilling system;

an arrangement for identifying a current location of the system and for correlating the current location with said geographic database to identify at least one local requirement for the current location; and

a controller configured to compare the local requirement for the current location to a current operational mode of the system and, in response to a mismatch between the local requirement and the current operational mode, disable override of the local requirement.
