# upscale\_steadystate\_implicit(1)

Upscale two-phase relative permeability

## NAME

upscale\_steadystate\_implicit - Upscale two-phase relative permeability

## SYNOPSIS

upscale\_steadystate\_implicit \[option=value\] \[option=value\] ...

## DESCRIPTION

Upscale two-phase relative permeability for different saturations and pressure gradients. For each saturation point, the model is initialized with capillary equilibrium. Then for each pressure drop points, the transport solver is run until steady state is reached and relative permeabilities are computed from the phase mobilities.

Example usage:

upscale\_steadystate\_implicit fileformat=eclipse filename=grid.grdecl rock\_list=rocklist.txt boudary\_condition\_type=0

## OPTIONS

**fileformat** Grid format, eclipse or cartiesian. Defaults to cartesian.\
 **filename** Grid filename.\
 **rock\_list** A file with a list of one file name per satnum specifying two phase properties for each rock type.\
 **boundary\_condition\_type** Boundary condition type.
