Oilfield nanoparticles: Synthesis, characterization and application.

Transport Experiments• Breakthrough experiments: Nanoparticles wereinjected into a test calcite columns, which is 7.5cmlength with porosity of 0.41 to test the mobility ofnanoparticles in porous media.• Inhibitor return experiments: Nanoparticles areinjected halfway into a calcite column, followed byan overflush solution, 18 hours shut-in, and inhibitorreturns are monitored by injecting a calcite saturatedbrine (60,000 mg/L TDS, 1000 mg/L Ca, pH 5.6) tomonitor the inhibitor return.
