PLMIXPAR
Recognised by the OPM Flow parserPROPS
The PLMIXPAR keyword defines the Todd-Longstaff210 Todd, M. and Longstaff, W. “The Development, Testing and Application of a Numerical Simulator for Predicting Miscible Flood Performance,” paper SPE 3484, Journal of Canadian Petroleum Technology (1972) 24, No. 7, 874-882. mixing parameters for when the polymer option has been activated by the POLYMER keyword in the RUNSPEC section. This keyword must be present in the input deck if the POLYMER keyword has been activated.

Note that this keyword is used only for the polymer option, if the MISCIBLE keyword in the RUNSPEC section has been invoked then in addition the TLMIXPAR keyword is also required to define the Todd-Longstaff mixing parameters for the MISCIBLE option.
Notes:
The keyword is followed by NPLMIX tables as declared on the REGDIMS keyword in the RUNSPEC section, for each rock region. There should be only one row per table.
Each entry 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
