... and understand the responsible mechanisms at scales ranging from nano-scale to field scale. The ionic formulation of the injected brine affects dramatically the crude oil/brine/rock interfaces, altering rock wettability and improving oil recovery efficiency. In this experimental work, a mechanistic study...

... and coreflooding experiments tailored towards a thorough understanding of the LSWE. Seawater and low salinity brines deprived of one divalent ion were prepared while maintaining theirionic strength. Our data shows that reducing brine ionic strength results in wettability alteration which led to improved oil...

... Water-based muds (WBMs) and oil-based muds (OBMs) can be used as DIF. Each type of mud has advantages and disadvantages. Selection of the type of fluid to be used depends on the application and reservoir characteristics. WBMs use brine as a base fluid to minimize the solids content. The added...
