Abstract
A system for evaluating a geological formation in a bottom hole assembly (BHA) includes a vibration mechanism configured to use mechanical energy provided by a mechanical energy source to produce a plurality of vibration beats at a predetermined frequency at the BHA. At least one vibration sensor detects the plurality of vibration beats generated by the vibration mechanism. A controller generates a waveform responsive to the detected plurality of vibration beats. The waveform is generated in a first configuration when the geological formation has a first geological characteristic and the waveform is generated in a second configuration when the geological formation has a second geological characteristic.
