Abstract: Drill bit vibration data for lateral, axial, and torsional directions of a drill bit is collected for a simulated or deployed drill bit for visualization of 3D coupled vibration. A frequency converter transforms the drill bit vibration data into frequency vibration data. A drill bit analyzer identifies local maxima (“peaks”) in the frequency vibration data in each of the lateral, axial, and torsional directions. Common peaks across all 3 directions with sufficiently high frequency and sufficiently high bit rotation speed are indicated as 3D coupled vibration. A drill bit data visualizer uses the indications of 3D coupled vibration in addition to the vibration data and frequency vibration data to generate visualizations of 3D coupled vibration in the drill bit.

Abstract: Transmitting and receiving mud pulse pressure waves at a downhole device. The mud pulse pressure waves may be transmitted from a surface mud pulser and/or by a downhole mud pulser to a downhole device. The mud pulse pressure waves may be detected directly by a transducer or indirectly by detecting physical changes induced in the downhole tool by the pressure waves of the mud pulse. The detected physical changes can be converted to a digital signal for use by the downhole tool. The mud pulse pressure waves may encode information including data, or instructions to the downhole devices.
