After primary and secondary recovery processes more than ٥٠ percent of oil remains in reservoirs. Therefore, for more recovery from these reservoirs, methods of enhanced oil recovery should be applied. On the other hand, with increasing energy demand and depletion of conventional hydrocarbon resources, the oil and gas industry needs new technological developments to increase recovery rate, and productivity index. Thus, the industry needs to employ more efficient ways for exploration and production of oil and gas. Therefore, advanced technology like Nanotechnology should be coming to overcome the problem of low recovery from reservoirs. This study focuses on application of polysilicon Nanoparticles as one method for improving oilrecovery. In this paper all aspects of utilization of polysilicon Nanoparticles in enhanced oil recovery is introduced and the potential opportunity and challenges that face are also discussed.
