Enlarging the bandwidth of seismic images

Abstract


Low frequencies are very important in seismic imaging. They penetrate deeper and they are indispensable in impedance estimation. High frequencies enhance the resolution and provide detailed information. In this paper the following three steps are proposed to realize ultra wideband seismic images: a) broaden the linear bandwidth during acquisition by applying DSAs (dispersed source arrays), b) add the missing ultra-low frequency information (trend) from migration velocities, indispensable for impedance images, and c) add the missing ultra-high frequency information (detail) by data obtained from borehole measurements, particularly for reflectivity images.
