Abstract

Low frequencies are most important in seismic imaging. They enhance the resolution, penetrate deeper and they are indispensable in impedance estimation. In this paper a fourstep approach for enhancing the low frequencies in marine acquisition and (pre)processing is proposed: 1) positioning the sources and detectors at the optimum depth, 2) carrying out proper deghosting and 3) (pre)processing the low frequencies separately. In step 4), the missing ultra-low frequency information (trend) comes from the velocity distribution and from modern gravity gradiometry.
