Abstract:
1. A method for estimating relative permeability for fractional multi-phase, multi-component fluid flow through a porous medium comprising steps of: (a) creating a three dimensional digital representation of a porous medium comprising scanning a sample of the porous medium using a scanning device to make an image of the porous medium and segmenting the image to produce the three dimensional digital representation of the porous medium; (b) performing a first or precursor simulation over a first computational domain of the three-dimensional digital representation of the porous medium, wherein the first computational domain extends from an inlet plane to an outlet plane and a selected storage plane is located between the inlet and outlet planes, which comprises: (c) performing a second simulation over a second computational domain of the three-dimensional digital representation of the porous medium sample, wherein the second computational domain is defined by said storage plane which represents an inlet plane for the second computational domain and said outlet plane used in the precursor simulation, which comprises
