A Study of Nanoparticles Application in Different Oil and Gas Reservoir Rock Types

Applicability of nanoparticle in oil and gas industry has brought much attention, particularly in enhanced oil recovery. Various factors including reservoir type, geological properties, wettability of the surface and fluid distribution influence efficient production from reservoir. Employing nanofluid for wettability alteration has been of great importance and provide favorable wettability state. Wettability alteration of reservoir rock increases production rate and reduces the residual saturation of the fluid in the porous medium. Reservoir rock surface consists of minerals with different adsorption properties that can influence wettability of the rock. In this paper, a fundamental of wettability is explained furthermore, the ability of different nanoparticles in wettability alteration of different rock types are investigated for enhanced recovery from oil and gas reservoirs with certain rock type.
