The flowing material balance (FMB) analysis provides the capability to include pressure-dependent permeability and rock compressibility in the analysis.
In the Plot Options section, click the AG FMB checkbox.
In the Material Balance Options section, click the GeoMechanical checkbox. This enables the geomechanical correction (see geomechanical reservoir models), which uses inputs from the Properties editor (under Formation / Rock Properties -> Geomechanical).
Note: For the Oil FMB analysis, this option is only available if the Changing Properties (Pseudo-Pressure) option is selected.
