Several stochastic modeling methods for fluvial reservoirs

Fluvial reservoirs play a very important role in the petroleum industry of China. It is difficult to describe fluvial reservoirs by conventional methods because of the serious heterogeneity of such reservoirs. The appearance of stochastic modeling technique seems to bring a light to this problem. It can integrate various information and characterize heterogeneous reservoirs correctly. In this article, some popular stochastic modeling methods for fluvial reservoirs are introduced, including Boolean simulation, sequential indicator simulation, truncated Gaussian simulation, object based simulation and hierarchical object based simulation. At the same time, their respective advantages and shortcomings are also analyzed. These methods can characterize the heterogeneity of the fluvial reservoirs and can quantitively evaluate their uncertainty.
