摘要： This subject disclosure describes methods to build and/or enhance 3D digital models of porous media by combining high- and low-resolution data to capture large and small pores in single models. High-resolution data includes laser scanning fluorescence microscopy (LSFM), nano computed tomography (CT) scans, and focused ion beam-scanning electron microscopy (FIB-SEM). Low-resolution data includes conventional CT scans, micro computed tomography scans, and synchrotron computed tomography scans.

摘要： Methods for upscaling digital rock modeling data are described. Core-plug samples for pore-scale modeling are strategically chosen using whole-core minipermeability grids and conventional CT (Computed Tomography) scans. Pore models or pore-network models are used for flow modeling. Computed numerical SCAL (Special Core AnaLysis) properties are validated using laboratory-derived data, then they are used to populate borehole-scale models. Borehole-scale models use MPS (Multi-Point Statistics) to combine minipermeability grids and conventional CTscans of whole core with electrical borehole images to create 3D numerical pseudocores for each RRT (Reservoir Rock Type). SCAL properties determined from pore-scale models are distributed for each petrophysical facies in numerical pseudocores. Effective SCAL properties computed from various MPS borehole-scale realizations or models are used to populate interwell-scale models for each RRT. At the interwell scale, seismic attributes and variogram statistics from LWD (logging while drilling) data are used to populate digital rock models. Effective properties computed from flow simulations for interwell volumes are used to populate full-field scale models. At the full-field scale, outcrop analogs, sequence stratigraphy, forward stratigraphic models, diagenetic models, and basin-scale models are combined using MPS to improve flow simulations. At every stage, REVs (representative element volumes) are computed to be certain rock heterogeneities have been captured.

摘要： The subject disclosure relates to methods for determining representative element areas and volumes in porous media. Representative element area (REA) is the smallest area that can be modeled to yield consistent results, within acceptable limits of variance of the modeled property. Porosity and permeability are examples of such properties. In 3D, the appropriate term is representative element volume (REV). REV is the smallest volume of a porous media that is representative of the measured parameter.
