Abstract

Channelized submarine systems are often gathered into complexes and display various stacking patterns. Their internal architectures represent one of the fundamental properties of a reservoir because they impact the connectivity of sand-rich bodies and affect hydrocarbons recovery. Some works have analyzed the static connectivity of various stacking patterns; however, few have qualitatively evaluated the dynamic implications of different stacking patterns on fluid flow circulations. For this reason, we analyze the hydrodynamic responses of several stacking patterns considering a set of many stochastic realizations grouped into three categories, where each category considers one particular stacking pattern setting. To study the hydrodynamic responses, we set a two-phase system containing oil and water, quantify the oil recovery efficiency, the water breakthrough time, and we compute the dissimilarities between the saturation maps at a specific time equal to 0.5 the injected pore volume. The metrics and dissimilarities are then visualized using heat maps and two-dimensional representations based on multidimensional scaling. This approach facilitates the comparison among flow simulations and quantitatively evaluates the differences of stacking patterns in a channelized submarine meandering reservoir. Moreover, our method permits us to estimate the relation between static and dynamic metrics descriptions.
