Abstract: A drilling system can comprise a drill string having a longitudinal axis and comprising at least one drill rod and a wireless sub coupled to the at least one drill rod. The wireless sub can comprise processing circuitry that is configured to detect mechanical impulses of the drill string. The processing circuitry can be configured to wirelessly transmit signals indicative of the mechanical impulses to a remote computing device.

Abstract: Described is apparatus housing an instrumented device and an inner tube providing a fluid flow path therethrough. A strain gauge is on the outer surface of the inner tube. Bulkhead(s) transfers forces from an external housing to the inner tube to be detected by the strain gauge. Flow sensors measure fluid flow velocity and/or fluid flow volume rate. Pressure sensors sense pressure differential between an inlet side and an outlet side of the apparatus. Sensors provide for measurement of RPM, WOB, azimuth and rate of penetration. Communication means (such as a Wi Fi transceiver) and/or GPS device can communicate through EM transparent windows. The apparatus is used aboveground axially in-line in a drill string.
