`PMISC`

Recognised by the OPM Flow parserPROPS

PMISC defines the transition between immiscible and miscible displacement as a function of oil pressure tables, for when the MISCIBLE keyword in the RUNSPEC section has been activated. If this keyword is absent from the input deck and MISCIBLE keyword in the RUNSPEC keyword has been activated, then miscibility is independent of the oil phase pressure.

Notes:

The keyword is followed by NTMISC tables as declared on the MISCIBLE keyword in the RUNSPEC section.

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

Each table is terminated by a “/” 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	Field	Metric	Lab	Default
1	`DATA` manual: `PRESS`	A columnar vector of real monotonically increasing down the column values that defines the oil phase pressure.	DOUBLE	Pressure, 1	psia	barsa	atma	None
2	`MISC`	A columnar vector of real equal or increasing down the column values that defines the corresponding miscibility factor. MISC is a scaling that should lie be zero and one, where zero means no miscibility and one means full miscibility.			dimensionless	dimensionless	dimensionless	None

Example

--
-- MISCIBILITY VERSUS PRESSURE TABLES
--
PMISC
-- OIL MISCIBILE
-- PRESS FACTOR
-- ------- ---------
1000.0 0.000
2000.0 0.250
3000.0 1.000
4000.0 1.000 / TABLE NO. 01
-- OIL MISCIBILE
-- PRESS FACTOR
-- ------- ---------
1500.0 0.000
2000.0 0.000
2500.0 0.250
3000.0 0.350
3500.0 1.000
4000.0 1.000 / TABLE NO. 02
The above example defines two miscibility versus pressure tables assuming NTMISC equals two and NSMISC is greater than or equal to six on the MISCIBLE keyword in the RUNSPEC section.
