Abstract
  In recent years, the use of natural surfactants as surface active agents in chemical methods of oil recovery over chemical surfactants has been under consideration due to the absence of environmental problems. In this study, a new plant, Albizia julibressin (Albizia), was introduced as a natural surfactant. ...  Read More

http://dx.doi.org/10.22050/ijogst.2018.98264.1410

Abstract
  In this paper, the potentials of using particles, especially nanoparticles, in enhanced oil recovery is investigated. The effect of different nanoparticles on wettability alteration, which is an important method to increase oil recovery from oil-wet reservoirs, is reviewed. The effect of different kinds ...  Read More

Volume 4, Issue 4 , Autumn 2015, , Pages 50-66

http://dx.doi.org/10.22050/ijogst.2016.12479

Abstract
  Efforts to enhance oil recovery through wettability alteration by nanoparticles have been attracted in recent years. However, many basic questions have been ambiguous up until now. Nanoparticles penetrate into pore volume of porous media, stick on the core surface, and by creating homogeneous water-wet ...  Read More

4. A Laboratory Investigation into Wettability Alteration of Carbonate Rock by Surfactants: The Effect of Salinity, pH, and Surfactant Concentration

Volume 3, Issue 3 , Summer 2014, , Pages 1-10

http://dx.doi.org/10.22050/ijogst.2014.6617

Abstract
  Wettability alteration is an important method for increasing oil recovery from oil-wet carbonate reservoirs. Chemical agents like surfactants are known as wettability modifiers in carbonate systems. Oil can be recovered from initially oil-wet carbonate reservoirs by wettability alteration from oil-wet ...  Read More

5. An Experimental Investigation of Wettability Alteration in Carbonate Reservoir Using γ-Al2O3 Nanoparticles

Volume 3, Issue 2 , Spring 2014, , Pages 18-26

http://dx.doi.org/10.22050/ijogst.2014.6034

Abstract
  Wettability alteration is one of the most important methods for oil recovery from sandstone and carbonate reservoirs. The effects of salinity, pH, temperature, and chemicals such as surfactants and fatty acids on the alteration of the wettability were described in previous studies. In recent years, attention ...  Read More
