Abstract: Disclosed is a process for characterising the evolution of a reservoir that comprises non-horizontal layers, by analyzing the changes of at least the seismic amplitudes of seismic reflections. The process comprises the steps of providing a base survey of the reservoir with a set of seismic traces at a first time and providing a monitor survey of the reservoir, taken at a second time, with a set of seismic traces associated to the same positions as in the base survey. The sets of seismic traces from the base and monitor surveys are then inverted to obtain an estimate of the changes having occurred in the time interval between base and monitor surveys, the inversion being performed using seismic traces for which allowance is made for the actual propagation paths through the non-horizontal layers of the reservoir.
