Abstract

Seismic amplitude anomalies have been observed at the Maguelone site in the course of sub-surface gas injection experiments. To allow the interpretation of the seismic monitoring in terms of physical parameter changes, various modelling attempts were conducted that all share the elastic wave theory principles. We show in this presentation that we cannot reproduce the experimental results with this theory, thus some form of anelastic energy dissipation would be required.
