| Abstract: |
| One of the biggest obstacles of the EOR processes using water flooding is low viscosity and so high mobility ratio of water that causes fingering and channeling of injected water into producing well. Gel polymer controls the water flow in high permeability areas, so its injection before water flooding would enhance sweep efficiency of operation. Nanoparticles can help in gel polymer tracking in reservoirs, enhance its movement profile, change the reservoir rock properties in favor of gel polymer and finally change the gelling time of the gel polymer. Fe3O4 nanoparticles usage in combination with gel polymer has been considered in this research. One of the efficient factors for improving efficiency of gel polymer injection is using nanoparticles as strong compound in gellant. In this research Fe3O4 paramagnetic nanoparticles was produced by a novel coprecipitation- hydrothermal method and was added to gellant solution. Fe3O4 nanoparticles (NPs) and various surface modifications such as PFG, Amine, organosiloxane and fatty acid were prepared in this work for the first time. SEM, XRD and DLS tests were done to determine the properties of synthesized nanoparticles, and obtained results showed that size distribution of nanoparticles is in a good conformity with commercial samples. In addition, rheological tests were performed on HPAM gellant solution containing Fe3O4 (NPs) along with different hydrophilic Fe3O4 nanoparticles and without them to investigate their effects on rheological behavior of obtained solution. The optimum concentration of these nanoproducts in improving rheology of solution was determined. |
