Can we decrease uncertainties in deep-water channelized reservoirs by knowing how channels stack within channel complexes? Subsurface data cannot effectively characterize key parameters such as net-to-gross and connectivity. Nevertheless, sub-seismic scale stratigraphic architectures and heterogeneities constitute building blocks of deep-water reservoirs and need to be understood and captured during the reservoir modeling and field development stages. Deep-water channel complex outcrop analogs provide the opportunity to relate sub-seismic scale reservoir parameters to seismic-scale Previous HitstackingNext Hit patterns. We propose a new graphical method called the Channel Previous HitStackingNext Hit Matrix to relate the vertical and lateral Previous HitstackingNext Hit of successive channels within channel complexes to key observed reservoir parameters.

This study uses data from sixteen deep-water channel complex outcrops from the Capistrano (California), Grès d’Annot (France), Brushy Canyon (Texas), Karoo (South Africa) and the Ross (Ireland) Formations, totaling eighty three channels. Each channel complex shows different internal Previous HitstackingNext Hit patterns with various vertical, lateral and oblique Previous HitstackingNext Hit trends. Those channel complex Previous HitstackingNext Hit patterns plotted on the Channel Previous HitStackingNext Hit Matrix indicate that: (1) eighty five percent of the channel complexes are getting more aggradational toward later fills, (2) eighty five percent of the channel complexes show increase of net-to-gross when the individual channels are less laterally dispersed within the channel complexes, and (3) the reservoir connectivity increases when channel stack vertically and/or obliquely. These results can help to better calibrate reservoir models of deep-water channelized reservoirs and can be used for better prediction of subsurface reservoir parameters when channel complex Previous HitstackingNext Hit pattern are seismically resolvable.
