WebIntegration of Leverett J-function analysis with Gassmann’s equations allows the time-lapse change of seismic reflectivity to be expressed explicitly in terms of the change of the … 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 expected reservoir changes is limited to selected strata. The most common time-lapse inversion schemes do not make use of this a priori information fully or properly.
