WebThe time-lapse seismic data is usually used to monitor changes in reservoir conditions (Schmitt, 2004). The most important a priori information of time-lapse data is that the … Webthe repeated data-sets along the time (Figure 1). A typical final processing product is a time-lapse different data-set, where we can assess to the amplitude differences between the seismic and therefore the elastic changes of the reservoir. The differences should be close to zero, except where reservoir changes have occurred. Using time-lapse ...
