Abstract
Seismic diffractions are often considered as noise and during processing it has been suppress intentionally or implicitly. Diffraction hyperbola actually have information of true diffraction, wave propagation and/or fracture waves which always contain valuable information of subsurface and helps in better imaging and reservoir characterization. Using double radical equation and synthetic data we examine the diffraction hyperbola behaviour using different velocity and depth. We observe that, at abrupt change of velocity diffraction is produced which is an indication of fault and fracture.
