Horizontal directional drilling area network and methods
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.

a table that applies a ranking to the differing types of said data logs such that said drilling area network hub transfers one type of data log before another type of data log to the remote location on the Internet according to the table and violation of the pull-back tension threshold increases the ranking of the pull-back tension log for transfer.
