Аннотация:This paper discusses methods for interpolating the well data that describes a hydrocarbon reservoir. The main difficulty lies in the requirement that the interpolation result should correspond not only to borehole data but also to some additional criteria, such as variograms and histograms. In a broader sense, it should reflect our knowledge of the geological environment. The authors are interested in what capabilities the different stochastic methods, sequential Gaussian simulation (SGS), multiple-point statistics (MPS) and fuzzy model simulation, can provide.
