Todd-Longstaff Model Characteristic curves

The Todd-Longstaff model requires the definition of the capillary pressure between the hydrocarbon phase (oil + solvent) and the water. Relative permeabilities are needed for the water and the hydrocarbon phases.

Todd-Longstaff saturation properties by tables - example

CHARACTERISTIC_CURVES tl_sat_prop_table_example
  KRW_TABLE swfn_table
  KRH_TABLE sof2_table
  TABLE swfn_table
    PRESSURE_UNITS Pa
    EXTERNAL_FILE swfn_file.dat
  END
  TABLE sof2_table
    EXTERNAL_FILE sof2_file.dat
  END
