NAME

       upscale_relpermvisc - Upscale two-phase relative permeability

SYNOPSIS

       upscale_relpermvisc  [option=value]  [grid file] [rock file 1] [rock file 2] [rock file 3]
       ...

DESCRIPTION

       Upscale two-phase relative permeability in the  capillary  limit  for  lithofacies  models
       described by Eclipse corner point grids.

       Example usage:

       upscale_relpermvisc -bc p grid.grdecl swof1.inc swof2.inc

       For isotropic input, the rock file has four columns, and looks like this:

       -- Stone 1 -- Sw           Krw             Kro     J-func
         1.42000E-01  0.00000E+00  1.00000E+00  2.25999E+00
         2.79250E-01  1.93652E-03  5.03619E-01  5.76122E-02
         4.14850E-01  1.09648E-02  2.36036E-01  -1.23421E-02
         6.14150E-01  4.10007E-02  3.95006E-02  -8.96693E-02
         7.26100E-01  1.41398E-01  9.30808E-03  -1.19849E-01
         9.48000E-01  8.40000E-01  0.00000E+00  -1.42553E+00

OPTIONS

       -bc  Which  boundary  conditions  to use. Possible values are p (periodic), f (fixed) or l
       (linear). Defaults to f.
       -points Number of saturation points to upscale for, uniformly distributed. Defaults to 30.
       -waterViscosity Viscosity of water given in Pascal seconds (1000 cP = 1 Pa s).
       -oilViscosity Viscosity of oil given in Pascal seconds (1000 cP = 1 Pa s).
       -waterCurve The column number in the rock files that represent relative  permeability  for
       water. Defaults to 2.
       -oilCurve  The  column  number  in the rock files that represent relative permeability for
       oil. Defaults to 3.
       -outputWater Filename for where to  write  upscaled  values  for  water  relperm.  If  not
       supplied, output will only go to the terminal (standard out).
       -outputOil  Filename  for where to write upscaled values for oil relperm. If not supplied,
       output will only go to the terminal (standard out).
       -interpolate If this option is used, the outputted  values  will  be  interpolated  values
       using  the supplied number of points (integer larger than 0). Monotone cubic interpolation
       is used, and will thus produce a smooth curve for a few number of saturation points.
       -minPerm Minimum floating point value allowed for phase permeability in  computations.  If
       set to zero, some models can end up singular. Defaults to 1e-12.
