摘要
A method for creating a reservoir fades model is disclosed. A S-grid is created which is representative of a subterranean region to be modeled. A training image is constructed which includes a number of fades. The training image captures fades geometry, associations and heterogeneity anrtong the facies. A fades probability cube corresponding to the S-grid is derived from a geological interpretation of the facies distribution within the subterranean region. Finally, a geostatistical simulation, preferably a multiple-point simulation, is performed to create a reservoir facies model which utilizes the training image and facies probability cube and is conditioned to subsurface data and information. Ideally, the facies probability cube is created using an areal depocenter map of the facies which identifies probable locations of facies within the S-grid.
