... ABSTRACT When we delineate oil and gas reservoir in complex structural or lithologic controls. AVO analysis will be applied with either common-image gathers (CIGs) or common-midpoint (CMP) gathers. Different gathers may draw distinct conclusions, thus correct gathers are vital for AVO analysis...
