In-situ Polymerization of Hydrophobic Polymer Nanocoating (HPNC) over Hydrophilic Polymer Nanoparticles (HPNP) to Optimize EOR Process

There are many limitations with the existing polymer flooding technology such as thermal, mechanical, shear, and biological degradation of polymer chains during flooding process. [1-3].Many works have been done to overcome the above mentioned limitation in polymer flooding with polymericsolutions. Recently, encapsulation and intelligent delivery studies have been considered as a sophisticated approach for protection and controlled release of precious materials inmany fields [4]. A novel core-shell structure of HPNC and HPNP designed and prepared to intellectually control mobility ratio in oilreservoirs and overcome weakness and limitations of classical polymer flooding. These particles can release HPNP at oilwater interface at reservoir temperature where the flooding water should have the maximum viscosity
