| Abstract | Deep water oil reservoirs buried more than 500m possess high temperature and high pressure conditions, which caused failure to most of the oil recovery methods involving fluid injection. A non-invasive electromagnetic (EM) wave transmission system coupled with nanofluid injection has been proposed to improve recovery factor of an oil reservoir. Interactions of the dielectric nanoparticles at low frequency radio wave range are mainly ionic and interfacial polarization, which could be manipulated to disturb the compatibility at oil-water interfaces. An attempt to measure oil recovery due to interaction of EM waves with dielectric nanoparticles has been performed. In this work, zinc oxide, ZnO nanoparticles synthesized via sol-gel method formed single phase hexagonal wurzite structure at temperature 300°C. As confirmed by X-ray diffraction (XRD), average ZnO crystals size was 45nm, with the major growth in [100] direction. ZnO nanofluid was prepared by dispersing ZnO nanoparticles in deionized water and ultrasonicated for 2 hours, which was then injected into a packed glass bead column of 24 cm length and having permeability of 380 mD, to replicate the reservoir material. Prior to this injection, the column was saturated with Arabian Heavy crude oil of viscosity 16.31 cp at 25°C, followed by water flooding to recover 71% of the original oil in place (OOIP). After 30 minutes exposure to electromagnetic wave radiation and nanofluid injection simultaneously, it has successfully recovered 26% of the remaining oil. It is expected that interaction between EM waves and ZnO nanoparticles in the column will induce atomic vibration on the pore surfaces and as a consequence, released the trapped oil. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
