WSEGDFMD

Recognised by the OPM Flow parserSCHEDULE

The WSEGDFMD keyword defines a multi-segment well’s drift flux slip model definition that sets the type of slip model to be used. A slip model335 Shi, H., Holmes, J.A., Durlofsky, L.

The option is activated by the FLOWOPT parameter on the WELSEGS keyword in the SCHEDULE section; however, the slip model flow calculation is not available in OPM Flow.

See also the WSEGDFIN keyword that sets the slip model’s input parameters and the WSEGDFPA keyword that allows the model default values employed by WSEGDFMD to be modified..

This keyword is not supported by OPM Flow but would change the results if supported so the simulation will be stopped.
