Application of Pre-Stack Wave Equation Datuming to Remove Interface Scattering in Sub-Basalt Imaging

O-17 APPLICATION OF PRE-STACK WAVE EQUATION DATUMING TO REMOVE INTERFACE SCATTERING IN SUB-BASALT IMAGING F. MARTINI and C.J. BEAN Dublin University College Belfield Dublin 4 Ireland 1 Summary Interface roughness affects deeper reflectors imaging and continuity. The effect is even stronger when a moderate to strong acoustic impedance contrast is present in the shallow surface. Sub-basalt imaging has been a problem of general interest in the last few years in petroleum industry. Previous work has already demonstrated that energy transmission into and propagation though the basalt does occur. The imaging problem in sub basalt imaging seems to be related mostly
