Quantification and characterization of interaction between nanoparticles and fines suspension

This research was conducted to study the effect of using nanoparticles on the migration of fines through the pore throat in the reservoir formation. A different types of nanoparticles were used to find the most effective nanoparticles among them to be applied in the real situation in future. A laboratory work such as static adsorption test, zeta – potential, FESEM – EDX analysis and soaking test were performed to analyse the samples. Static adsorption test is important to know the stability of the samples (glass beads) with nanoparticles. FESEM – EDX analysis was used during this experiment to visualize the real effect of using nanoparticles in term of their ability of attachment with nanoparticles which lead to fines migration prevention. Zeta potential was measured by using zeta potential analyser whereas soaking test experiment was conducted by using bentonite and different concentration of nanoparticles to measure the rate of adsorption hence to find the most effective nanoparticles that can be used to prevent the movement of fines in the pore throat. From the experimental results, MgO with 1.0% became the most effective nanoparticles used to prevent fines movement due to higher adsorption rate from soaking test experiment.
