OPM Flow Keyword Reference

DUALPORO

Recognised by the OPM Flow parserRUNSPEC

The DUALPORO keyword activates the Dual Porosity option for the run. In a dual porosity system flow occurs between the matrix and the fracture only, whereas in a dual permeability system flow also occurs between the matrix grid blocks81 Warren, J.E. and Root, P.J. 1963.

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