Abstract

With various kinds of data, such as Zero Vertical Seismic Profile (VSP), 3D VSP, multiple directional Walkaway VSP and full azimuth seismic data, the Vertical Transverse Isotropy (VTI) and Horizontal Transverse Isotropy (HTI) characteristics of plutonic igneous rock are studied, and an approach to estimate the pseudo anisotropy for HTI media is presented. It is concluded that the target zone has a little HTI characteristics and spatial variation of HTI can reduce the difference between forward moveout and first break observation of reflection. The relative variant HTI parameter by single direction respectively can describe the transversely anisotropy of media. Spatial variation of HTI estimated is consistent with the real fracture orientation and can predict fracture reservoirs.
