F032 Rock Physics Depth Trend Analysis Based on Stacking Velocity P. Hoang* (Odin Petroleum A.S.) P.A. Avseth (Rock Physics Technology A. S.) B. Ursin (Norwegian University of Science and Technology) & A.J. van Wijngaarden (Norsk Hydro) SUMMARY In this paper we present methodologies to obtain rock physics properties as a function of burial depth i.e. rock physics depth trends (RPDTs). Several authors have suggested using rock physics models calibrated to well log data or constrained by diagenetic models to obtain empirical RPDTs. We present an alternative way to extract seismic RPDTs from seismic stacking velocities. At well locations we use
