Investigation into the effect of silica nanoparticles on the rheological characteristics of water-in-heavy oil emulsions

Abstract The effect of silica nanoparticles on the rheological characteristics of water-in-heavy oil emulsions has been investigated. Enhanced oil recovery methods for heavy oil production (most especially, thermal fluid injection) usually result in the formation of water-in-oil (W/O) emulsion. In r...
