`PLYVISC`

Recognised by the OPM Flow parserPROPSSCHEDULESPECIAL

Variant 1 — PROPS section

PLYSVISC defines the polymer viscosity scaling factors used to determine the relationship of pure water viscosity with respect to increasing polymer concentration within a grid block. The polymer option must be activated by the POLYMER keyword in the RUNSPEC section in order to use this keyword.

The BRINE option in the RUNSPEC should be deactivated if this keyword is to be used.

Notes:

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

Each table must contain a minimum of two rows and a maximum of NPPVT rows as declared on the TABDIMS 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: `POLCON`	A columnar vector of real monotonically increasing down the column values that defines the polymer concentration in the solution surrounding the rock. The first entry should be zero to define a no polymer concentration.	DOUBLE	Concentration, 1	lb/stb	kg/sm3	gm/scc	None
2	`VISFAC`	A columnar vector of real increasing or equal values that defines a factor that scales the effective viscosity of the solution for the given POLCON entry. Normally VISFAC value for the first row in the table should be one.			dimensionless	dimensionless	dimensionless	None

The example defines two polymer viscosity scaling factor tables, based on the NTPVT variable on the TABDIMS keyword in the RUNSPEC section being equal to two and NPPVT variable on the same keyword being greater than or equal to six.

Variant 2 — SCHEDULE section

PLYSVISC defines the polymer viscosity scaling factors used to determine the relationship of pure water viscosity with respect to increasing polymer saturation within a grid block. The polymer option must be activated by the POLYMER keyword in the RUNSPEC section in order to use this keyword.

See PLYVISC – Define Polymer Viscosity Scaling Factorsin the PROPS section for a full description.
