SCALECRS
Recognised by the OPM Flow parserPROPS
The SCALECRS keyword sets the end-point scaling option to be either two-point or three-point scaling, for when the End-Point Scaling option has been invoked by the ENDSCALE keyword in the RUNSPEC section. This determines which end-points on the relative permeability curves are used for scaling based on the supplied end-point arrays (SGCR, SWCR, etc.).
Notes:
The keyword is terminated by a “/”.
The end-point scaled for each option and the arrays used in the end-point scaling are summarized in the following table:

Parameters
| No. | Name | Description | Type | Default |
|---|---|---|---|---|
| 1 | VALUEmanual: SCALEOPT | SCALEOPT is a character string that sets the end-point scaling option and should be set to either NO or YES: NO: Activates two-point end-point scaling. YES: Activates three-point end-point | STRING | NO |
Example
--
-- TWO-POINT END-POINT SCALING IS NO THREE POINT IS YES
--
-- SCALEOPT
-- ---------
SCALECRS
YES / SCALING OPTION
The above example activates three-point end-point scaling of the relative permeability curves.
