THE SYNERGIZATION OF SILICA NANOPARTICLE AND SODIUM DODECYL SULFATE FOR CHEMICAL FLOODING APPLICATION

Nowadays, enhanced oil recovery is vital in improving the recovery. However, productions keep depleting due to production problem such as high surface tension and interfacial reservoirs. Therefore, chemical flooding one of methods used The synergy between Silica nanoparticle Sodium Dodecyl Sulfate has been proposed a compound for this project. major aim study was measure effectiveness synergization (SiO₂) nanoparticles SDS with different injection ratio by measuring using flooding. After surfactant nanosilica solution take place, test have conducted identify optimum concentration. results showed that concentration 2000 ppm (ST) (IFT) are 33.5 36.0 mN/m respectively. When SiO₂ were added, it 6000 reduction IFT 31.0 34.5 20,000 brine paraffin injected into sandpack followed waterflooding from experiment presented 23% 28% therefore, more left sandpack. Then, slug 0.1 0.5 tertiary It increases up 48% 64% ratio. As conclusion, proved applicable because can recover production.
