WebIn recent years, with the further development of old oilfields, in order to further improve the oil recovery, they must be conformance controlled. Among various types of conformance control methods, polymer gels composed of polymers and crosslinkers have attracted widespread attention because of their efficiency and low costs. WebAt 1.0 wt% NaCl, the NPs reduced oil recovery by XG solution between 5-12%, except for Fe(OH)3 and TiO2 NPs. These NPs increased the oil recovery between 2-3% by virtue of reduced polymer adsorption caused by the alkalinity of these nanopolymer sols. Additionally, the surface properties of SiO2, TiO2 and Al2O3 NPs were improved by polymer grafting.

WebEnhanced oil recovery (abbreviated EOR), also called tertiary recovery, is the extraction of crude oil from an oil field that cannot be extracted otherwise. EOR can extract 30% to 60% or more of a reservoir's oil, compared to 20% to 40% using primary and secondary recovery. According to the US Department of Energy, carbon dioxide and water are injected along … WebThe study defined the threshold concentration for TiO 2 NPs as 2.3 wt % while the improved oil recovery was attributed to the enhanced viscosity of the polymer. (98) Although most EOR research is based on conventional spherical nanoparticles, a novel core–shell polymer has been assessed for polymer flooding. high tibc levels but normal iron levels
