Abstract

The S-Zero Stack algorithm extracts robust density information of the subsurface from converted waves. The method is based on the separation of velocity effects from density effect analytically in a PS reflection equation (Aki & Richards, 1980); thus, a special stacking method can be designed to capture density variations at subsurface interfaces without going to inversion. This paper deals with practical aspects of the method. A reasonable workflow extracting subsurface density information is discussed. As a case study, the data of Eugene Island, Line 421 in the Gulf of Mexico is used and the resulting subsurface density anomalies are calibrated with the density log in Well EI 273 C9.
