Abstract: A method including obtaining, by a computer processor, a sonic waveform for each of a plurality of source and receiver positions along a borehole, and a sonic wave propagation velocity of a target event for the plurality of positions. Further, performing, a linear moveout correction on the sonic waveforms based on the velocity and stacking the linear moveout corrected waveforms to generate a stacked waveform at the plurality of positions. The method further includes determining an arrival-time of the target event on the stacked waveforms based on an extremum of a first objective and predicting a candidate arrival-time of the target event for the sonic waveform at the plurality positions based on the arrival-time of the target event on the stacked waveforms, and the sonic velocity.

Abstract: A method of realizing an shear wave propagation velocity anisotropy characterization within a display for a wellbore region including, obtaining a shear wave propagation velocity anisotropy intensity, and a shear wave propagation velocity anisotropy azimuth. A directional line segment is determined to represent the anisotropy for each of a plurality of measured depth points along the wellbore, and plotted on the display as a plurality of directional line segments to produce a 1-dimensional anisotropy characterization plot.
