Acquisition footprint is a term used to define linear spatial grid patterns seen on 3D seismic time slices. These patterns tend to ‘mirror’ parts of the acquisition geometry used for acquiring the seismic survey. They may be seen usually on shallow time slices or horizon amplitude maps as striations masking the actual amplitude anomalies under consideration for stratigraphic interpretation, AVO analysis and reservoir attribute studies [Marfurt et al, 1995, 1998]. Acquisition footprints may be present due to various reasons, but two general types of footprint could be distinguished. One type may be categorized as depending on the details of the acquisition geometry, and the other type as those arising from signal processing problems [Drummond et al. 2000]. |
Acquisition footprint is a phenomenon occurring in seismic images whereby amplitude variations relate to the survey geometry |
