SALT
Recognised by the OPM Flow parserSOLUTION
The SALT keyword defines the initial equilibration salt concentration values for all grid cells in the model and should be used in conjunction with the PBUB, PDEW, PRESSURE, RS, RV, SGAS, SGAS and SWAT keywords etc., to fully describe the initial state of the model. The keyword should only be used if the salt (brine) phase has been activated in the model via the BRINE keyword in the RUNSPEC section.
This is the non-standard method to initialize the model via enumeration and is seldom employed in the industry. The standard methodology is for OPM Flow to initialize a model using the parameters on the EQUIL keyword combined with other keywords to fully describe the initial state of the model. The keyword can be used with all grid types.
Notes:
The number of entries should correspond to the NX x NY x NZ parameters on the DIMENS keyword in the RUNSPEC section, unless the BOX keyword defines a sub area of the grid, in which case the total number of entries should correspond to the number of cells defined by the BOX statement.
The keyword is terminated by a “/”.
See also the PBUB, PDEW, PRESSURE, RS, RV, SGAS, SOIL and SWAT keywords to fully define the initial state of the model.
- Records
- Fixed number of records
- Record count
- 1
- Variadic
- The record accepts a variable number of items
Parameters
| No. | Name | Description | Type | Dimension | Field | Metric | Lab | Default |
|---|---|---|---|---|---|---|---|---|
| 1 | SALT_manual: SALT | SALT is an array of real positive numbers that are greater than or equal to zero assigning the initial equilibration salt concentration values to each cell in the model. Repeat counts may be used, for example 20*15.0. | DOUBLE | Concentration | lb/ | kg/ | gm/ | None |
Example
--
-- DEFINE INITIAL EQUILIBRATION SALT CONCENTRATION FOR ALL CELLS
-- BASED ON NX = 100, NY = 100 AND NZ = 3
--
SALT
10000*0.0000 10000*0.0000 10000*15.000 /
The above example defines the initial equilibration salt concentration values to be 0.0 kg/sm3 for all the cells in the first and second layers and finally a concentration of 15.0 kg/sm3 for all the cells in the third layer. This assumes that METRIC units have been declared in the RUNSPEC section.Related keywords
