Amplitude versus offset: a systems approach

Abstract

The information contained in amplitude-versus-offset (AVO) effects can be extremely useful in exploration/development work. A specialized set of techniques and software, however, is needed to extract and use this information properly. A systems approach has been developed at Berrong Enterprises Ltd to accomplish this goal. The system has as major components (1) AVO feasibility studies, (2) proper AVO data processing, (3) AVO scanning, (4) detailed AVO modelling supported by well logs, and (5) elastic model inversions at prospective locations. Each of these areas is discussed from an application/results viewpoint with practical examples from actual development problems. These examples will demonstrate the degree of information that is available in proper AVO information processing. Interpretation techniques to use this information are also presented.
