Seismic interpretation Seismic interpretation Principles of seismic stratigraphic Principles of seismic stratigraphic interpretation interpretation Seismic interpretation Seismic interpretation  Seismic stratigraphy is a technic for  Seismic stratigraphy is a technic for interpreting stratigraphic information from interpreting stratigraphic information from seismic data.. seismic data..  The resolution of the seismic reflection  The resolution of the seismic reflection follow gross bedding and as such they follow gross bedding and as such they approximate time lines. approximate time lines.  The key is that the contrast represented by seismic  The key is that the contrast represented by seismic lines come from bedding surface and not lateral lines come from bedding surface and not lateral variations (facies changes). variations (facies changes). Resolution of seismic data Resolution of seismic data  Understanding the  Understanding the resolution is resolution is importantfor the importantfor the seismic method. seismic method. – A) a single cycle – A) a single cycle sine 30Hz in sine 30Hz in medium
