`MSFN`

Recognised by the OPM Flow parserPROPS

The MSFN keyword defines the miscible normalized relative permeability tables for when the MISCIBLE and or SOLVENT options have been activated in the RUNSPEC section using the respective keyword. The MISCIBLE keyword invokes a three component formulation (oil, water and solvent gas or an oil, water and solvent oil). Whereas the SOLVENT keyword results in a four component model (oil, water and gas plus a solvent). This keyword should only be used if the MISCIBLE and or SOLVENT options have been activated.

Notes:

The keyword is followed by NTSFUN tables as declared on the TABDIMS keyword in the RUNSPEC section.

Each table must contain a minimum of two rows and a maximum of NSSFUN rows as declared on the TABDIMS keyword in the RUNSPEC section.

Each table is terminated by "/" and there is no "/" terminator for the keyword.

Records: Fixed number of records
Variadic: The record accepts a variable number of items

Parameters

No.	Name	Description	Type	Dimension	Default
1	`DATA` manual: `SGAS`	A columnar vector of real monotonically increasing down the column values starting from zero and terminating at one, that defines the gas plus solvent saturation.	DOUBLE	1, 1, 1	None
2	`KRSG`	A columnar vector of real values that are either equal or increasing down the column and that are greater than or equal to zero and less than or equal to one that defines the gas plus solvent relative permeability multiplier.			None
3	`KRO`	A columnar vector of real values that are either equal or increasing down the column and that are greater than or equal to zero and less than or equal to one that defines the oil relative permeability multiplier.			None

The above example defines two MSN tables for use the MISCIBLE and SOLVENT options.
