Selection of proxy modelling methods for streamline simulation to waterflooding management process in oil reservoirs

Proxy modelling which uses a number of predetermined reliable parameters due to its simplicity has been widely used for the analysis of gas and oil field development in comparison to the traditional mathematical three-dimensional (3D) hydrodynamic models. Among the reservoir models with simplified physics the streamline simulation is favorably characterized by its visibility and informativeness. In this work MATLAB as well as COMSOL Multiphysics modules were used for streamline simulation of flow in porous media using known volumes of injected and produced fluid in a reservoir with known permeability and porosity for sequential waterflood treatment. The comparative analysis showed that after one month of the treatment the front of the injected water advancement became smoother. Comparing the dynamics of the location of the lines characterizing the filtration state of the area before and after the impact on the reservoir, it was found that the productivity of production wells depends not only on how close they are located to the injection well, but also on the activity of the filtration zone. Based on an analysis of the preferred directions of fluid movement after sequential waterflooding, it was determined that oil in some previously unaffected areas was also displaced by the injected fluid. The results obtained by MATLAB and COMSOL Multiphysics modules were analyzed comparatively.
