WATVISCT

Recognised by the OPM Flow parserPROPS

WATVISCT defines the water viscosity as a function of temperature for when thermal option has been activated by the THERMAL keywords in the RUNSPEC. The reference pressure for this table is given by the VISCREF keyword in the PROPS section.

This keyword can only be used if OPM Flow’s thermal option has been activated by the THERMAL keyword in the RUNSPEC section. Note this is different to the commercial simulator that uses the TEMP keyword in the RUNSPEC section to activate the black-oil thermal model.

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

Example

The following example shows the WATVISCT keyword for when the thermal option has been activated by the THERMAL keyword in the RUNSPEC section and for when NTPVT on the TABDIMS keyword in the RUNSPEC section is set equal to one.
