摘要
- the present invention relates to a method in order to facilitate the monitoring during the time of the evolution of an underground zone for comparative analysis of a certain number of sets of seismic records obtained successively at the end of n successive seismic surveys (3d seismic "4d). - the method comprises the use of a technique of the pattern recognition applied to the set of seismic events of the n surveys considered and analysed simultaneously, which makes it possible to show the variations of the seismic events of the under - sol. - application to follow the changes occurring in a zone - the reservoir under - ground in the course of production, for example.
