INTRODUCTION

Exploration and exploitation of hydrocarbon reserves is becoming increasingly complex. To be successful, an increasing amount of information is required. In recent years much attention has been devoted to the information present in reflection amplitude variation with offset (AVO) (Balogh et al., 1986; Gelfand et al., 1986; Spratt, 1987; Chiburis, 1987; Ball, 1987; Lörtzer and Berkhout, 1988, 1989; Haas and Berkhout, 1988, 1989; Rijssen and Herman, 1988; SEG workshop, 1988). In principle, the offset variations of the P-P reflection amplitudes contain information on all the elastic parameter contrasts (P-wave velocity, S-wave velocity, and density), while the zero-offset reflection amplitude contains only information on the acoustic impedance.
