METHOD FOR FACILITATING THE TRACKING OVER TIME OF THE EVOLUTION OF A SUBTERRANEAN ZONE BY COMPARED ANALYSIS OF DIFFERENT SEISMIC RECORDING GAMES

摘要

P - The present invention relates to a method for facilitating the monitoring over time of the evolution of an underground zone by comparative analysis of a certain number n of sets of seismic records obtained successively after n successive 3D seismic campaigns (so-called 4D seismic) .- The method involves the implementation of a shape recognition technique applied to all seismic events of the n campaigns considered and analyzed simultaneously, which makes it possible to show the evolutions of the Seismic events in the basement - Application to monitoring changes occurring in a reservoir area of the basement during production, for example. /P
