Characteristic sinusoidal reflection time pattern

A vertically fractured layer in the earth produces a VVAz response that can be observed on P-wave seismic data. When the data are sorted into Common-Offset, common-Azimuth (COCA) gathers, a characteristic sinusoidal reflection time pattern is observed (see image below) that corresponds to P-waves traveling parallel (Vfast) and perpendicular (Vslow) to near-vertical fractures.

Measure of anisotropic intensity and direction

The FracVEL technique utilizes this moveout information to estimate azimuthal interval velocities. A measure of anisotropic intensity and direction can then be determined, highlighting target zones of interest (see image below).
