Application of 3D Seismic Diffraction Imaging for Detecting Shallow Subsurface Inhomogeneities

Recently, a new method for detecting shallow subsurface objects utilizing the waves diffracted by these objects has been proposed. The method suggests that every subsurface point is a possible location of a point diffractor. Imaging of the diffractors is performed by stacking seismic energy in 3D space. The result of the imaging is a 3D volume in which prominent diffraction anomalies appear at spatial locations close to the target objects. <br>Application of the method is illustrated by a synthetic example and three case studies demonstrating imaging of various subsurface objects under various geological conditions.<br>
