  • Publication number: 20230046288
    Abstract: Methods and systems are presented in this disclosure for modeling fluid diversion in an integrated wellbore-reservoir system. A mathematical model for fluid diversion in a reservoir formation of the integrated wellbore-reservoir system is generated by capturing, within the model, combined effects of formation treatments by foaming agent and by a chemical agent (such as resin) that imposes skin effect and permeability reduction to the formation. The generated model can be employed to simulate treatment of the reservoir formation by the foamed resin system. Based on results of the simulated treatment, treatment of the reservoir formation by the foamed resin system can be initiated for fluid diversion among layers of different permeabilities in the reservoir formation.
