Abstract:
1. A method of simulating flow of a single and incompressible fluid in a heterogeneous porous medium using a flow simulator, comprising: discretizing the heterogeneous porous medium by a grid containing cells; determining at each cell of the grid a permeability field from measurements obtained by at least one of logging measurements, seismic measurements and experimental measurements; developing a flow simulator which is implemented by a computer wherein a diffusivity equation is translated in a frequency domain, the diffusivity equation relating permeability of the heterogeneous porous medium to a pressure gradient and to a filtration rate of the heterogeneous porous medium wherein the diffusivity equation is modified according to Neumann's formula and wherein the modified diffusivity equation is solved by an iterative solution using fast Fourier transforms to accelerate computation of the iterative solution; and using the flow simulator to determine at each cell of the grid a pressure gradient and a filtration rate from the permeability values determined from the measurements.
