Patent number: 11525345Abstract: A method for modeling hydrocarbon recovery workflow is disclosed. The method involves obtaining, by a computer 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. The method may include determining, by the computer processor, a multi-phase Darcy model for the reservoir region of interest using the reservoir data and the stimulation data. The multi-phase Darcy model determines a fluid phase flow rate using a pressure gradient, an absolute permeability value, and a relative permeability value. The method may include determining, by the computer 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.Type: GrantFiled: July 14, 2020Date of Patent: December 13, 2022Assignee: SAUDI ARABIAN OIL COMPANYInventors: Moataz Abu AlSaud, Subhash Ayirala, Ali Yousef
