摘要
method for monitoring over time the evolution of physical state of an area of an underground formation, such as a reservoir by using seismic data and interpretation.the method exploits the seismic pattern recognition, in particular a fuzzy discriminant analysis technique to incorporate the uncertainties on the seismic measurements in the interpretation.the uncertainties considered are evaluated on parts of seismic traces obtained during the successive seismic campaigns, corresponding to areas of the underground formation (out of the tank, where the natural conditions were not changed significantly by application. in the monitoring of the evolution of an oil reservoir in the course of production, for example.
