Abstract
A method of monitoring a COgeological storage site by locating the COplume from 4D seismic data is disclosed. A stratigraphic inversion of the seismic data is performed in order to obtain the P and S impedances, before and after COinjection. A density variation cube and an incompressibility modulus variation cube are constructed from the seismic impedances. The free COplume is located within the subsoil by identifying, within the cubes cells where the density variation is negative and where the incompressibility modulus variation is negative, which are of an absolute value greater than a given positive threshold.
