Abstract
A method of estimating flow properties of an earth formation includes: selecting a grid block representing a region of the earth formation, the region including at least one of an area and a volume of the earth formation, the grid block including a plurality of grid cells and having an orientation defined by grid axes; and calculating a fluid flow model of the region. Calculating the model includes: estimating a principal flow direction for each grid cell; adjusting the orientation of the grid block based on the principal flow direction; and calculating fluid flow parameters in each grid cell to generate the fluid flow model.
