Recent advances in seismic lithologic analysis

Abstract An objective of seismic analysis is to quantitatively extract lithology, porosity, and pore fluid content directly from seismic data. Rock physics provides the fundamental basis for seismic lithology determination. Beyond conventional poststack inversion, the most important seismic lithologic analysis tool is amplitude-variation-with-offset (AVO) analysis. In this paper, I review recent progress in these two key aspects of seismic lithologic analysis.
