پۆختەی سمینار: 

Demand for energy is growing rapidly, and current primary and secondary oil production techniques are insufficient to meet the world’s petroleum demand. So, to establish a stable fossil fuel energy supply, the petroleum industry must rely on tertiary enhanced oil recovery techniques. These enhanced oil recovery (EOR) techniques can be categorized into the major types, such as chemical enhanced oil recovery (CEOR), carbon dioxide enhanced oil recovery (CO2-EOR), microbial enhanced oil recovery, and thermal enhanced oil recovery, and the minor types, such as alkaline surfactant polymer in CEOR and steam injection or in situ combustion in thermal enhanced oil recovery Although studies have been conducted on each EOR technique,1 most have been undertaken as single-parameter optimizers. However, the optimum combination of cross-linked minor techniques can maximize the performance of each major EOR technique by optimizing multiple parameters. Among the major EOR techniques, CEOR which uses chemicals to minimize the interfacial tension and alter the wettability of oil wet formations and as mobility control optimizer agents has produced the most significant benefits to oil recovery in the past decade. By optimizing the above-mentioned key parameters for increasing oil recovery, CEOR has attracted ever-increasing numbers of publications and patents. The ability of a single smart agent to optimize interfacial tension (IFT), wettability alteration, and mobility control may be the best complementary hybrid application of CEOR agents. Nanocomposites contain one or multiple conventional materials and can be defined as individual smart matters containing inherent properties of composed materials in intensified states. The logic behind using nanoparticles (NPs) in the subsurface formation is that the nanoscale size of such particles is much smaller than the size of pore throats. Thus, these NPs can effortlessly pass through the microporous media reaching deep formations of oil reservoirs. The power of objectively oriented, synthesized nanocomposites in spontaneous optimization of water-oil IFT and wettability in hydrocarbon reservoirs enhances oil recovery. Small droplets of oil that are present in pore structures are the result of high capillary forces in the reservoirs. Therefore, geo mechanical modifications, including reducing the tension in the water-oil interface and altering wettability toward being water-wet, can improve oil recovery significantly by lessening the introduction of capillary forces into the system. 
This webinar presents the introduction on the application of nanotechnology in enhanced oil recovery. Theoretical and experimental aspects of appliance of nanotechnology assisted hybrid methods have been introduced and presented. Including mechanisms affecting the parameters which could be effective in oil recovery enhancement are exemplified. Experimental procedures and the outcomes are also presented and explained.
