Abstract: A drilling system includes an internal assembly comprising a chassis, a flow diverter, or both, and a strain gauge coupled to the chassis, the flow diverter, or both, in which the strain gauge is configured to output a signal associated with a strain deformation of the internal assembly. The drilling system also includes a drill collar coupled to the internal assembly, in which the internal assembly extends along the drill collar, and the drill collar encloses the internal assembly of the internal assembly such that a strain deformation of the drill collar causes the strain deformation of the internal assembly.

Abstract: Embodiments of the present disclosure relate to a tangible, non-transitory, computer-readable medium that stores instructions executable by one or more processors, in which the instructions cause the one or more processors to determine a threshold value associated with an axial acceleration oscillation amplitude at a drill bit, in which the drill bit is a part of a drilling system. The instructions further cause the one or more processors to receive an operating parameter value of the drilling system, compare the operating parameter value with the threshold value, and adjust an operation of the drilling system in response to comparing the operating parameter value with the threshold value.

Abstract: Changes to the vibrational frequencies of a drill string or BHA are monitored for prognostic health monitoring purposes. When one or more orders of resonance frequencies deviate from a baseline frequency, the magnitude of the deviation, and possibly the rate of deviation, is evaluated. When the deviation exceeds a threshold value, an alert is triggered. The alert may be triggered by downhole processing of the vibration data and conveyed to an operator to allow changes in operational parameters or removal of the component from the wellbore. The alert may instead be triggered by post-run processing of stored and dumped data, that can be used to evaluate whether the tool can be re-run, or whether it should be inspected, repaired, or scrapped.

Abstract: A method for removing material with a bit includes rotating a bit in a first direction, changing the rotational direction and rotating the bit in an opposing second direction. Rotation of the bit in the first direction and rotation of the bit in the second direction both remove material.
