A process-based model of a geological volume of interest is generated. The process-based model is conditioned with conditioning information associated with the geological volume of interest. Statistics are generated from the process-based model that represent parameters of the geological volume of interest locally. These statistics are used to constrain one or more geostatistical models of the geological volume of interest.

System and method for generating a geostatistical model of a geological volume of interest that is constrained by a process-based model of the geological volume of interest

A method for creating a facies probability cube is disclosed. A S-grid containing facies is first created. The grid includes layers of cells and columns of cells. Vertical facies proportion data for the layers of cells is derived from sources such as well data, conceptual vertical geologic sections and graphs describing the proportion of facies found in each of the layers. Areal depocenter maps are created which have defined boundaries to create depocenter regions in which respective facies are likely to occur. Ideally, the boundaries for the depocenter regions for each of the facies are sequentially and independently defined. Horizontal or map facies proportion data are generated for the columns of cells preferably by filtering the depocenter regions so that the proportion of each of the facies ranges from a maximum value to a minimum value. The vertical and horizontal facies proportion data are then integrated to create a facies probability cube in which the cells are assigned probabilities for the occurrence of facies.
