.TH UPSCALE_RELPERMVISC "1" "October 2023" "upscale_relpermvisc 2023.10" "User Commands"
|
|
.SH NAME
|
|
upscale_relpermvisc \- Upscale two-phase relative permeability
|
|
.SH SYNOPSIS
|
|
upscale_relpermvisc [option=value] [grid file] [rock file 1] [rock file 2] [rock file 3] ...
|
|
.SH 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

.SH OPTIONS
|
|
\fB\-bc\fR Which boundary conditions to use. Possible values are p (periodic), f (fixed) or l (linear). Defaults to f.
|
|
.br
|
|
\fB\-points\fR Number of saturation points to upscale for, uniformly distributed. Defaults to 30.
|
|
.br
|
|
\fB\-waterViscosity\fR Viscosity of water given in Pascal seconds (1000 cP = 1 Pa s).
|
|
.br
|
|
\fB\-oilViscosity\fR Viscosity of oil given in Pascal seconds (1000 cP = 1 Pa s).
|
|
.br
|
|
\fB\-waterCurve\fR The column number in the rock files that represent relative permeability for water. Defaults to 2.
|
|
.br
|
|
\fB\-oilCurve\fR The column number in the rock files that represent relative permeability for oil. Defaults to 3.
|
|
.br
|
|
\fB\-outputWater\fR Filename for where to write upscaled values for water relperm. If not supplied, output will only go to the terminal (standard out).
|
|
.br
|
|
\fB\-outputOil\fR Filename for where to write upscaled values for oil relperm. If not supplied, output will only go to the terminal (standard out).
|
|
.br
|
|
\fB\-interpolate\fR 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.
|
|
.br
|
|
\fB\-minPerm\fR Minimum floating point value allowed for phase permeability in computations. If set to zero, some models can end up singular. Defaults to 1e-12.
