Heavy oil are the most world’s oil resources, viscous hydrocarbons that are difficult and costly to produce and refine. With a potential of up to 70% of the world's oil reserves, production from heavy oil reservoirs has many challenges especially in the case of high viscosity resulting in heavy oil reservoirs difficult to flow. Some techniques to reduce viscosity of heavy oil have been known before, such as using well-known process such as steam injection, steamsoak, and in situ combustion. Steam injection (cyclic steam, huff n puff) has been most successful, frequently by use of cyclic steam, followed by steam flooding. However, these techniques have limitations especially on the depth of the well.Electromagnetic heating (EM) Is a new technique that developed which does not require a heat transporting fluid, which can be particularly beneficial for deep reservoir and thin pay-zones where conventional methods are not cost-effective due to excessive heat loss through the adjacent formation. On the basis of this, the study was selected to improve thermal recovery by using microwaves that by adding nano fluid to artificial cores. This technique works by the principle of electromagnetic induction where microwaves will induce water particles and nano ferrofluids in the reservoir which will heat the oil so that its viscosity decreases. This study was simulated using artificial cores on a laboratory scale, temperature changes were observed on artificial cores which added variations of nanostructures using varying power.
