Carbonate and sandstone reservoirs wettability improvement without using surfactants for Chemical Enhanced Oil Recovery (C-EOR)

摘要

In this paper, we have been proposed the preparation of Silica-MWCNT nanohybrid that can increase the water wettability of carbonate and sandstone reservoirs. Chemical agents such as surfactants have been used as wettability modifiers to increase oil recovery from oil-wet carbonate and sandstone reservoirs. Addition of chemical compounds such as polymers, ionic materials and nanoparticles can improve the effectiveness of the mentioned chemical agents.
