Summary:
A18 ACQUISITION GEOMETRY INFLUENCE ON ANGLE- DEPENDENT AMPLITUDES IN A 3D SUBSALT SITUATION Abstract 1 A subsurface image that is obtained from seismic data after data processing can be biased by the acquisition geometry: it contains an acquisition footprint. For a proper evaluation of the influence of the acquisition geometry on image quality in areas of complex geology for example in subsalt situations a method is needed that can handle complex situations with irregular structures and large contrasts. Focal beam analysis is a method with a strong link to wave theory and therefore enables a quantitative analysis of image quality
