Dix inversion
WebABSTRACT Seismic sequences are stratigraphic units of relatively conformable seismic reflections. These units are intervals of similar sedimentation conditions, governed by sediment supply and relative sea level, and they are key elements in understanding the evolution of sedimentary basins. Conventional seismic sequence analyses typically rely … http://sepwww.stanford.edu/gp280/Syllabus_20240401.pdf
