Abstract
Disclosed is a method of modelling a subsurface volume. The method comprises: discretizing said subsurface volume to define a grid comprising an array of cells (), each cell being defined by cell faces, each cell having attributed thereto one or more high order properties (A,B); dividing each cell into a plurality of sub-cells, said plurality of sub-cells comprising: a plurality of central sub-cells adjacent a center of the cell, and a plurality of peripheral sub-cells, each adjacent a corresponding cell face; for each of said central sub-cells, and for each of said peripheral sub-cells for which the cell adjacent to that peripheral sub-cell has attributed thereto the same one or more high order properties as that of the cell in which said peripheral sub-cell is comprised, attributing one or more low order property values (c, d, e, x, y, z) in accordance with the high order property attributed to the cell in which said peripheral sub-cell is comprised; for each of said peripheral sub-cells for which the cell adjacent to that peripheral sub-cell has attributed thereto a different one or more high order properties than that of the cell in which said peripheral sub-cell is comprised, attributing one or more low order property values (c, d, e, x, y, z) in accordance with the high order property attributed to the adjacent cell; and determining one or more low order property values for each cell based on the one or more low order property values attributed to each cell's component sub-cells.
