PLYADS

Recognised by the OPM Flow parserPROPSSPECIAL

Variant 1 — PROPS section

The PLYADS keyword defines the rock polymer adsorption tables for when the polymer option has been activated by the POLYMER keyword in the RUNSPEC section. Alternatively, the functions can be entered via the PLYADSS keyword in the PROPS section for when salt sensitivity is to be considered.

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 a “/” and there is no “/” terminator for the keyword.

See also the PLYADSS keyword in the PROPS section to also define rock polymer adsorption tables when the polymer concentration is a function of salinity.

Parameters

No.NameDescriptionTypeDimensionFieldMetricLabDefault
1DATA
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.DOUBLEConcentration, 1lb/stbkg/sm3gm/sccNone
2POLRATIOA columnar vector of real increasing down the column values that defines the mass of adsorbed polymer per unit mass of rock. The first entry should be zero to define a zero ratio of polymer concentration.lb/lbkg/kggm/gmNone

The above example defines two polymer rock adsorption tables assuming NTSFUN equals two and NSSFUN is greater than or equal to eight on the TABDIMS keyword in the RUNSPEC section.
There is no terminating “/” for this keyword.

Variant 2 — SCHEDULE section

The PLYADS keyword defines the rock polymer adsorption tables for when the polymer option has been activated by the POLYMER keyword in the RUNSPEC section. Alternatively, the functions can be entered via the PLYADSS keyword in the PROPS section for when salt sensitivity is to be considered.
