    en.wikipedia.org/wiki/Ultrasonic/sonic_driller/corer

    The Ultrasonic/Sonic Driller/Corer (USDC) is a drilling device that uses vibrations in order to hammer its bit through materials, as opposed to traditional drilling methods. The drill uses a piezoelectric actuator as its source of power, and utilizes a variety of 'horns' to vibrate, or hammer, its bit through the material.

    Moreover, drilling deep holes in parts can prove difficult as the abrasive slurry will not effectively reach the bottom of the hole. [9] Note, rotary ultrasonic machining is efficient at drilling deep holes in ceramics because the absence of a slurry cutting fluid and the cutting tool is coated in harder diamond abrasives. [1]

  4. Theory of sonics - Wikipedia

    en.wikipedia.org/wiki/Theory_of_sonics

    A sonic drill head works by sending high frequency resonant vibrations down the drill string to the drill bit, while the operator controls these frequencies to suit the specific conditions of the soil/rock geology. Torque Converter. [4] A mechanical application of sonic theory on the transmission of power by vibrations.

  5. Sonic logging - Wikipedia

    en.wikipedia.org/wiki/Sonic_logging

    Many relationships between travel time and porosity have been proposed, the most commonly accepted is the Wyllie time-average equation. The equation basically holds that the total travel time recorded on the log is the sum of the time the sonic wave spends travelling the solid part of the rock, called the rock matrix and the time spent travelling through the fluids in the pores.

  6. Formation evaluation - Wikipedia

    en.wikipedia.org/wiki/Formation_evaluation

    Modern sonic configurations with pingers and microphones at both ends of the log, combined with computer analysis, minimize the averaging somewhat. Averaging is an advantage when the formation is being evaluated for seismic parameters, a different area of formation evaluation. A special log, the Long Spaced Sonic, is sometimes used for this ...

  8. Density logging - Wikipedia

    en.wikipedia.org/wiki/Density_logging

    The tool itself initially consisted of a radioactive source and a single detector, but this configuration is susceptible to the effects of the drilling fluid. In a similar way to how the sonic logging tool was improved to compensate for borehole effects, density logging now conventionally uses 2 or more detectors. In a 2 detector configuration ...
