New 4D Seismic Tools For Carbonate Reservoirs

Carbonate reservoirs are often significantly more<br>demanding to explore and produce than siliciclastic<br>reservoirs. The reasons for this are typically complex<br>depositional facies with intense fracturing and diagenetic<br>effects as compaction induced subsidence.<br>Time-lapse seismic monitoring of carbonate reservoirs<br>might identify subsidence and the flow properties<br>of the fracture network, which often make up migration<br>paths for hydrocarbons or injector fluids.<br>Knowing these dynamic components of the reservoir<br>behavior helps the asset team to improve the management<br>of the produced water and detect by-passed<br>pay.<br>In this paper we present a set of new timelapse seismic<br>analysis tools, for mapping these dynamic reservoir<br>features and demonstrate their performance at<br>hand of a couple of real data examples.
