Diffraction Imaging in Hard-rock Environments

Herein, we expand and use the method used by Landa and Keydar (1998) to detect local heterogeneities. The method relies on computing local semblance along the diffraction offset-traveltime curves. We expand the method by taking into account the phase change occurring for edge diffractions. We demons...

Description
Summary:Herein, we expand and use the method used by Landa and Keydar (1998) to detect local heterogeneities. The method relies on computing local semblance along the diffraction offset-traveltime curves. We expand the method by taking into account the phase change occurring for edge diffractions. We demonstrate the usefulness of the method on hard-rock seismic data.
