Abstract
Acoustic properties of geological section are the source for estimating of important reservoir characteristics such as lithology or porosity. The advantages of borehole seismic over surface seismic make VSP data attractive for calculation of high-resolution acoustic (AI) and shear elastic (SEI) impedance sections. On the other hand there are a number of factors affecting amplitude anomalies related to reflector acoustic properties variations. This study was performed to find the way of offset VSP data processing<br>preserving true amplitudes.
