SPOLYMW
Recognised by the OPM Flow parserSOLUTION
The SPOLYMW keyword defines the initial equilibration polymer molecular weights for all grid cells in the model and should only be be used with OPM Flow's Polymer Molecular Weight Transport option, together with the other standard equilibration keywords, in order to fully describe the initial state of the model.
This keyword should only be used if the POLYMER and POLYMW keywords in the RUNSPEC section are also activated.
Note
This is an OPM Flow specific keyword that employs an alternative polymer flood model based on a Polymer Molecular Weight Transport equation, that is not available in the commercial simulator.
The model has been tested using metric units; however, using either field or laboratory units with the option should be considered experimental.
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.

Parameters
| No. | Name | Description | Field | Metric | Lab | Default |
|---|---|---|---|---|---|---|
| 1 | SPOLYMW | SPOLYMW is an array of real positive numbers that are greater than or equal to zero assigning the initial equilibration polymer molecular weights to each cell in the model. Repeat counts may be used, for example 20*5.0 | lb/ | kg/ | gm/ | 0,0 |
Example
--
-- INITIAL EQUILIBRATION POLYMER MOLECULAR WEIGHTS FOR ALL CELLS

-- ARRAY CONSTANT ---------- BOX ---------
-- I1 I2 J1 J2 K1 K2
EQUALS
SPOLYMW 0.0000 1* 1* 1* 1* 1 5 / LAYERS 1 TO 5
SPOLYMW 5.0000 1* 1* 1* 1* 6 7 / LAYERS 6 TO 7
SPOLYMW 0.0000 1* 1* 1* 1* 8 20 / LAYERS 8 TO 20
/
The above example defines the initial equilibration polymer molecular weights to be 0.0000 for all the cells, except for layers six to seven, where the polymer molecular weight is set to five for these cells.
