Annotation:
This article concernes the application of the MATLAB Reservoir Simulation Toolbox (MRST) for modeling polymer waterflooding processes, used as an enhanced oil recovery method. A review of key MRST modules, such as ad-core, ad-blackoil, ad-eor and ad-props, is presented, which include numerical solutions for flow problems considering the viscoplastic properties of polymer solutions, adsorbtion on the rock surface and changes in reservoir permeability. The methodology of creating the simulation model is presented and a numerical experiment is conducted to analyze the impact of polymer concentration on the final displacement efficiency. The simulation results demonstrate the effectiveness of using MRST for modeling polymer waterflooding. The use of this open-source software enhances the efficiency of reservoir development in fields with high heterogeneity.
