WebABSTRACT We simulated wireline borehole sonic waveforms to appraise modal frequency dispersions across fractured and thinly bedded formations. Simulations included monopole and dipole sources of excitation and explicitly took into account the borehole, the mandrel tool, and casing whenever present. Calculations were performed in the frequency domain … WebBecause the drill bit is attached to the bottom of the casing, the sonic method also advances a casing as the borehole is advanced. The sonic drilling method provides a rock core as the borehole is advanced however the core is often broken up so rock coring using a diamond core bit is preferred if rock core is required for logging, sampling, or ...
