RVW

Recognised by the OPM Flow parserSOLUTION

The RVW keyword defines the initial equilibration vaporized water in gas ratio values for all grid cells in the model and should be used in conjunction with the PBUB, PDEW, PRESSURE, RV, SGAS, SOIL and SWAT keywords etc., to fully describe the initial state of the model. The keyword should only be used if both gas and water phases have been activated in the model via the GAS and WATER keywords, and the VAPWAT is also present activating OPM Flow’s Vaporized Water Model. All the aforementioned keywords are 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, RV, SGAS, SOIL and SWAT keywords to fully define the initial state of the model.

Note

This is an OPM Flow specific keyword for the simulator’s Water Vaporization Model that is activated by declaring that vaporized water is present in the run using the VAPWAT keyword in the RUNSPEC section.

Use the command line option --enable-opm-rst-file=true to output the RVW data to the RESTART file.

An array of values covering the grid

Parameters

Example

--
-- INITIAL EQUILIBRATION WATER VAPOR IN GAS RATIO VALUES FOR ALL CELLS
-- BASED ON NX = 100, NY = 100 AND NZ = 3
--
RVW
1000*0.0000 1000* 0.0000 1000*1.3000 /
The above example defines the initial equilibration gas-vaporized water values to be 0.000 for all the cells in the first and second layers and 1.3000 for all the cells in the third layer.
| Note This is an OPM Flow specific keyword for the simulator’s Water Vaporization Model that is activated by declaring that vaporized water is present in the run using the VAPWAT keyword in the RUNSPEC section. Use the command line option --enable-opm-rst-file=true to output the RVW data to the RESTART file. |
