`PLYSHEAR`

Recognised by the OPM Flow parserPROPSSPECIAL

Variant 1 — PROPS section

The PLYSHEAR keyword activates and defines the polymer shear thinning-thickening option for when the polymer option has been activated by the POLYMER keyword in the RUNSPEC section.

This keyword is not supported by OPM Flow but would change the results if supported so the simulation will be stopped.

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: `VELOCITY`	A columnar vector of real monotonically increasing down the column values that defines the water-polymer flow velocity. The VELOCITY value for the first row in the table should be zero.	DOUBLE	Length/Time, 1	feet/day	m/day	cm/hour	None
2	`VISFAC`	A columnar vector of real values that defines a factor that scales the effective water and polymer viscosities for when shear thinning-thickening of the polymer occurs. Normally VISFAC value for the first row in the table should be one.			dimensionless	dimensionless	dimensionless	None

The above example activates the polymer shear thinning-thickening option and defines two polymer shear thinning-thickening 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

The PLYSHEAR keyword activates and the defines the polymer shear thinning-thickening option for when the polymer option has been activated by the POLYMER keyword in the RUNSPEC section.

See PLYSHEAR – Activate and Define Polymer Shearing Parametersin the PROPS section for a full description.

Records: Fixed number of records
