Evaluation and Classification of Different Nanoparticles for Enhanced Oil Recovery (EOR)

Nanotechnology due to enhance oil recovery (EOR), cost-effective production, and no damage to the environment has become very important in the oil industry. Nanoparticles used in EOR have dimensions below 100 nanometers. Depending on their size and material, their performances are different, and environmental conditions effects them. Nanoparticles increase the oil production of reservoirs by altering wettability, surface tension, and flow properties of fluids. Classification and determination of the best performance of nanoparticles, according to the material and size as well as the unique characteristics of reservoirs, are necessary and important. In this study, in addition to classification,we evaluate various studies that have been performed on different types of nanoparticles in EOR.
