SSFN
Recognised by the OPM Flow parserPROPS
The SSFN keyword defines the miscible normalized relative permeability tables for when the SOLVENT option has been activated in the RUNSPEC section using the respective keyword. The SOLVENT keyword results in a four component model (oil, water and gas, plus a solvent). This keyword should only be used if the SOLVENT option has been activated.
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.
- 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 | DATAmanual: SGAS | A columnar vector of real monotonically increasing down the column values starting from zero and terminating at one, that defines the gas plus solvent saturation ration which is defined as either: [S sub g over { left(S sub g ~+~ S sub s right) }]or or [S sub s over { left(S sub g ~+~ S sub s right) }] Where Sg is the gas saturation and Ss is the solvent saturation. | DOUBLE | 1, 1, 1 | dimensionless | dimensionless | dimensionless | None |
| 2 | KRGt | A columnar vector of real values that are either equal or increasing down the column and that are greater than or equal to zero and less than or equal to one that defines the gas relative permeability. The resulting gas relative permeability is calculated from: [k sub rg ~=~ k sub rgt left( S sub g ~+~ S sub s Right) {k sub rg} sup t] where krgt is the data in this column and krgt is the gas relative permeability from the SGFN keyword. | dimensionless | dimensionless | dimensionless | None | ||
| 3 | KRSt | A columnar vector of real values that are either equal or increasing down the column and that are greater than or equal to zero and less than or equal to one that defines the solvent relative permeability. The resulting solvent relative permeability is calculated from: [k sub rs ~=~ k sub rgt left( S sub g ~+~ S sub s Right) {k sub rs} sup t] where krSt is the data in this column and krgt is the gas relative permeability from the SGFN keyword. | dimensionless | dimensionless | dimensionless | None |
