Measurements are presented here in a rock physics template, which
was first published by Ødegaard and Avseth (2004) for sandstone and
shale. The rock physics template (RPT) is used as a tool for seismic interpretation
for lithology and pore fluid characterization. Authors presented
the model calculations to describe the relationship between vp/vs
ratio and acoustic impedance (vp ∗ density). They mention that the
RPT is basin-specific and influenced by local geological factors. Gupta
et al. (2012) present a data analysis from the Cambay Basin. They used
