Patent ID: 8725477

Claim:
A method for creating a 3-dimensional numerical pseudocore model comprising: a) obtaining logging data from a reservoir that includes depth-defined intervals of the reservoir, and processing the logging data into a portion of at least one interpretable borehole image data having unidentified borehole image data; b) examining one of the portion of the at least one interpretable borehole image data, the processed logging data or both to generate the unidentified borehole image data, then processing the generated unidentified borehole image data utilizing a multi-point statistics (MPS) algorithm FILTERSIM into the portion of the at least one interpretable borehole image data so as to generate fullbore image data; c) collecting at least one core from the reservoir and generating 3-dimensional digital core data from the collected at least one core sample using a computed-tomographic scan (CTscan), the generated digital core data representing one of features or structures of one or more depth-defined interval of the reservoir; d) pre-modeling the generated digital core data to define 3-dimensional sizes and shapes of petrophysical facies; e) using a multi-point statistics (MPS) algorithm SNESIM to generate realizations of numerical pseudocores for two or more petrophysical facies, and conditioning the realizations to match petrophysical facies sizes and shapes observed in the generated fullbore image data and the generated pre-modeled 3-dimensional digital core data; and (f) resampling the numerical pseudocores of step (e) to a radial grid, wherein the radial grid provides for a flow investigation of the numerical pesudocore model and includes building a cylindrical grid having one of one or more shapes or one or more layers, resampling the numerical pseudocore model from Cartesian coordinates, each voxel of which has a constant porosity or a constant permeability according to an associated rock type of the voxel, to cylindrical coordinates, wherein each cylindrical cell includes multiple Cartesian voxels of the numerical pseudocore model.
