Water-based fluid for altering the wettability of a formation

摘要

A method of altering the wettability of a reservoir formation involves flowing a fluid into the reservoir so as to coat the reservoir. The fluid may contain organic and inorganic components of nanoparticle size. The organic components may include silanes, alkoxysilanes with fluorinated chains or alkylcarbonyl. The inorganic components are selected from the group consisting of silicon, aluminium, titanium and zirconium.
