| Abstract: |
| Huge oil remains in reservoirs after the primary oil recovery, therefore; enhanced oil recovery (EOR) methods are used to produce more crude oil. The presence of nanoparticles as new and efficient materials in EOR has been highly regarded in recent decades. So, the main aim of this research is the usage of new silica nanoparticles containing various activators such as Al2O3, organosiloxane and amine reagents for surface modification and homogenized dispersibility in water based solution. Amine /organosiloxane / Al2O3 / SiO2 (AOAS) nanocomposite is synthesized using co-precipitation and hydrothermal method. This nanocomposite was characterized by FTIR and DLS. The contact angle is measured in order to investigate wettability alteration of oil-wetted carbonate rock sections via hydrophobic organosilane to strongly water-wet. The use of AOAS nanoproduct for flooding into a micromodel as a porous medium shows that the surface modification of this nanocomposite can improve the oil efficiency compared with commercial nanosilica and distilled water flooding. In other words, it was found that new AOAS nanocomposite is able to improve the oil recovery factor of five-spot glass micromodel through the EOR process, compared with commercial silica nanoparticles. |
