Method and system for modeling hydrocarbon recovery workflow

A computer system, comprising:

• a processor;
• and
• a memory coupled to the processor, the memory comprising functionality for:
• obtaining, by the processor, stimulation data and reservoir data regarding a region of interest, wherein the stimulation data describe a water flooding process performed in the reservoir region of interest by one or more enhanced-recovery wells;
• determining, by the processor, a multi-phase Darcy model for the reservoir region of interest using the reservoir data and the stimulation data,
• wherein the multi-phase Darcy model determines a fluid phase flow rate using a pressure gradient, an absolute permeability value, and a relative permeability value;
• determining, by the processor, a plurality of relative permeability values for the reservoir region of interest based on a plurality of fluid-fluid interface correlations and an interpolating parameter,
• wherein the interpolating parameter determines intermediate relative permeability values of an intermediate salinity-level caused by at least one fluid-fluid interface among the plurality of fluid-fluid interfaces;
• and
• determining an amount of hydrocarbon production based on a simulation of the reservoir region of interest using the plurality of relative permeability values.
