NAME

       upscale_relperm - Upscale two-phase relative permeability

SYNOPSIS

       upscale_relperm [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_relperm -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.
       -upscaleBothPhases Whether to upscale both phases or not. Defaults to true.
       -relPermCurve  If  upscaleBothPhases  is  false and input is isotropic, this specifies the
       column number in the rock-files to be upscaled. Defaults to 2.
       -jFunctionCurve If upscaleBothPhases is false and input is isotropic,the column number  in
       the stone-files that represent the Leverett J-function. Defaults to 4.
       -gravity Gravitational acceleration, in m/s². Use 9.8 for standard gravity. Defaults to 0.
       -fluids  Which  two-phase  fluid  system  we  are  dealing  with.  Possible  values are ow
       (oil/water) and go (gas/oil). Defaults to ow.
       -surfaceTension Surface tension in dynes/cm to use in  J-function/Pc  conversion.  Contact
       angle is not supported, and
       -waterDensity Density of water, in g/cm³. Only relevant for non-zero gravity. If fluids is
       set to go (gas/oil), this should be set to density of gas. Defaults to 1.0.
       -oilDensity Density of oil, in g/cm³. Only relevant for non-zero gravity. Defaults to 0.6.
       -output Filename for where to write upscaled values.
       -doEclipseCheck  Check  that  input  curves  includes  critical  saturation  points,  i.e.
       saturation points where relperms are 0. See critRelpermThresh. Defaults to true.
       -critRelpermThresh  If minimum relperm value is less than this value, it is set to 0. Only
       applicable if doEclipseCheck is true. Defaults to 1e-6.
       -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.
