Abstract

Designing of proper acquisition geometry is an optimizing exercise to achieve proper subsurface illumination by suitable placement of receivers and shots. Due to the resource constraint, most of the conventional surveys are carried out with lesser crossline sampling than inline sampling. The data is acquired generally in the dominant dip direction and perpendicular to the faults. This often leads to better imaging along the dip direction and slightly inferior strike direction imaging. The azimuthal content in the conventional geometry is often poor. Authors of this paper have tried to assess the impact of a wide azimuth survey upon structural delineation in geologically complex area. For this datasets acquired by three different geometries in the same area, were processed using the same processing flow including the processing parameters and the results were compared.
