| Summary: | Most oil reservoirs around the world are experiencing their second half of life. Hence, the necessity of
appropriate enhanced oil recovery (EOR) method as a more efficient technology gets further
importance. Nanotechnology is an advanced technology that has proved its potential to enhance oil
recovery. Innovative techniques are highly required in the oil and gas industry to meet the future
demand of the hydrocarbon fuels; significant efforts have been exerted on the development of new
innovative technologies to increase the oil recovery. Nanotechnology has provided new promising
approaches to enhanced oil recovery (EOR) techniques in matured and marginal fields. In this research,
the different concentrations of TiO2 and SiO2 nanoparticles were formulated and their properties have
been measured in terms of their application in enhancing oil recovery efficiency in high salinity reservoir
conditions. It was observed that 3wt% SiO2 nanoparticles solution yielded the highest tertiary recovery
of 26.67% compared to the 0.01wt% TiO2 nanoparticles solution that yielded 23.33%. SiO2 Nanoparticles
solutions also showed significant reduction in IFT values and contact angle measurements
compared to TiO2 nanoparticle solutions. 3wt% SiO2 concentration had the lowest IFT value of 5.26
dyne/cm and lowest contact angle of 12.09 ° compared to all the different nanoparticle concentrations
used in this research. Thus, it was concluded that 3wt% SiO2 nanoparticles solution was the optimum
concentration to be used in high salinity reservoir condition. |
