Horizontal directional drilling area network and methods

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.

What is claimed is: 
     
         1 . An apparatus for monitoring a system that performs horizontal directional drilling including a drill rig and a subsystem for monitoring the location of an inground tool along an underground borepath during an inground operation, said apparatus comprising:
 a drilling area network hub located above ground proximate to the drill rig for storing a plurality of data logs of differing types that characterize the inground operation as the inground operation is performed and said drilling area network hub is configured at least for intermittent Internet communication with a remote location; and   a priority table that applies a priority ranking to the differing types of said data logs such that said drilling area network hub transfers said data logs to the remote location on the Internet according to the priority table.   
     
     
         2 . The apparatus of  claim 1  wherein the differing types of data logs at least include a pull-back tension log, an annular fluid pressure log and a temperature log. 
     
     
         3 . The apparatus of  claim 2  wherein a maximum threshold value is associated with each of the pull-back tension log, the annular fluid pressure log and the temperature log.
