BRINE
Recognised by the OPM Flow parserRUNSPEC
The BRINE keyword activates the standard Brine Tracking model and optionally defines the water phase to have various salinities if the ECLMC keyword in the RUNSPEC section has been used to activate the Multi-Component Brine model, that allows for the water phase to have multiple water salinities. Note that the Multi-Component Brine model is not supported by OPM Flow.
Notes:
There is no data required for this keyword if the standard Brine Tracking option has been activated and there should be no terminating “/” in this case. However, if the Multi-Component Brine Tracking option has been invoked by the ECLMC keyword, a list of SALTS must be supplied and in this case the keyword is terminated by a “/”.
Note that when using the BRINE option the initial equilibration salt concentration should be defined using either the SALT or SALTVD keyword, and not the SALINITY keyword.
See also the PRECSALT and VAPWAT keywords in the RUNSPEC section that activates OPM Flow’s Salt Precipitation model, and the PVTWSALT keyword in the PROPS section to define the water properties with respect to salt concentration.
- Records
- Fixed number of records

- The record accepts a variable number of items
Parameters
| No. | Name | Description | Type | Default |
|---|---|---|---|---|
| 1 | SALTS | An optional character vector string that defines the salts to be tracked for when the Multi-Component Brine model has been activated by the ECLMC keyword in the RUNSPEC section. SALTS should be set to one or more of the following salt chemical formulae: | STRING | None |
Example
The first example activates the standard Brine model and has no terminating “/”.
