Paper Number: SPWLA-2022-0105
... is often carried out manually through visual inspection on a depth-by-depth basis. This is mainly because the dispersion data are represented by scattered and noisy points. Consequently, such a process is time-consuming and requires knowledge on sonic dispersion signatures. To automate sonic data...

... model is used as a reference to compensate for the dispersion effect, or a model-independent method, which optimizes nonphysical parameters to fit a simplified model to the field dispersion data extracted in the slowness-frequency domain. Many methods often require inputs such as mud slowness, frequency...

... sensitive to the near-borehole velocity change. This allows for developing an inversion method to estimate the radial change from the dispersion data. We also discuss the nonuniqueness issue of the inversion and ways to solve it. The dispersion data and the inversion results clearly demonstrate...
