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.
