GENERATION OF 3-DIMENSIONAL FLOW-FIELDS FOR STATISTICALLY ANISOTROPICHETEROGENEOUS POROUS-MEDIA

A methodology for generating three dimensional (3D) flow fields for st atistically anisotropic heterogeneous porous media is presented and de monstrated. The simulated flow fields are shown to exhibit the input s patial correlation structure and observe mass continuity. Sample flow fields are presented in the form of cross sectional slices of the 3D f ormation. These cross sections demonstrate visually the characteristic s of subsurface flow. The method was found to be faster than tradition al techniques in terms of its computational requirements. Given this m ethod, it is possible to generate the large number of realizations of a velocity field necessary to compute high order statistics in transpo rt problems.
