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 as part of a horizontal directional drilling system, said system including a drill rig and a portable locator for monitoring the location of an inground tool along an underground borepath, said apparatus comprising:

a telemetry system for wireless bidirectional communication between the portable locator and the drill rig, configured to transmit at least one telemetry signal having a transmission power and a transmit frequency;

a geographic database of region specific parameters that specifies operational parameters based on location of said 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 a set of local requirements for the telemetry signal at the current location that specify at least one of a maximum transmission power and at least one transmission frequency for the telemetry signal; and

a controller for setting at least one of the transmission power and the transmit frequency to conform to the set of local requirements.

2. The apparatus of claim 1 wherein the set of local requirements specifies at least one of a maximum transmission power and at least one transmission frequency for said telemetry signal and the controller sets at least one of the transmission power and the transmit frequency based on the specified maximum transmission power and the specified transmission frequency.

3. The apparatus of claim 1 wherein said arrangement comprises a GPS receiver.
