Training Basic Seismic Inversion

Training Basic Seismic Inversion

Course Description

Combining sequence seismic stratigraphy with the interpretation of Acoustic Impedance (AI) data is one of the latest developments in reservoir characterization. The course goal is to help interpreters of AVO data to avoid the avoidable and beware of the pitfalls that are incumbent with this method. Successes and failures of AVO analysis are studied. Successful AVO examples reveal the potential of this technique in finding new opportunities in a mature area
