Abstract

This work investigates the modeling and optimization of different flooding scenarios using three types of alkaline/xanthan gum/and SiO2 nanopowder at severe reservoir conditions of high temperature and high salinity. The rheological properties of the displacing fluids in addition to physical properties of the crude oil were investigated at simulated reservoir environment. Flooding runs conducted on linear sand pack assembly using different concentrations of the flooded slug. Moreover, the wettability alteration assessed at different slug concentrations. The results indicate that the higher oil recovery was achieved at 1.0 wt. % NaOH, 1000 ppm of xanthan gum and 0.05 wt. % SiO2.
