Wettability Alteration with Silica Aerogel Nanodispersion

Influence of Chemical Heterogeneity and Nanoscale Roughness on the DLVO Energy Interaction by Spherical Coordinates

“…As described in previous works [5,14,29], by increasing the two sphere radius ratio up to 50, the big sphere behaves as flat surface in front of small sphere. Details of the spherical coordinate integration method are considered in previous works [29] and in this work we show the ability of the developed method to predict the chemical heterogeneity of smooth particles, surfaces and rough particles on the DLVO energy interaction.…”

“…One of the main branches of nanomaterials is the colloidal systems which, are used in many important industries such as: paint, water treatment, enhanced oil recovery, biological systems, lubricants, coatings, pharmacy, metallurgy, plastics and etc. [2][3][4][5].…”

Stability of Nanoporous Silica Aerogel Dispersion as Wettability Alteration Agent

“…Results show that silica aerogels have immense potential in wettability alteration of reservoir rocks by adsorption and deposition mechanisms to mixed wet condition. [13] In this study, the stability of nanodispersions at reservoir conditions such as different brine composition, concentration and reservoir temperature are surveyed and discussed. Experimental results are also modeled using Derjaguin-Landau-Verwey-Overbeek (DLVO) and non-DLVO theories.…”

“…[4] Silica aerogel (SA) is a classic example of developing amorphous nanoporous materials which have applications in industries commercially, and many new applications under development. [5][6][7][8][9][10][11][12] Unique properties of SA such as large surface area, very low density, controllable hydrophilic or hydrophobic surface, stable properties up to 450 C and high porosity, enable their use as a wettability alteration agent in enhanced oil recovery (EOR) processes. [13] Wettability alteration of reservoir rock surface is one of the promising technologies for EOR.…”
