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.
