Heavy oil is characterized by oil density of 22.3o API or less. With potential up to 70% of world oil reserves, production of heavy oil reservoir has many challenges, especially in terms of high viscosity which is resulting heavy oil reservoir difficult to flow. One effective technique for producing heavy oil is thermal recovery. Thermal recovery technique that being used for this research is microwave combined with nano ferro fluid. With this technique, microwave will induce water particles and nano ferro fluid in the reservoir that will heat up the oil and lower its viscosity. Heating technique using microwave is carried out by incorporating the antenna into the well which can overcome any depth limitation that used to be found in thermal recovery techniques such as cyclic steam stimulation, steamdrive, and forward in-situ combustion.This research was conducted by a laboratory experiment to simulate reservoir in a form of sandpack for the microwave heating and artificial core for recovery factor. The microwave heating able to reduce oil viscosity from 4412.11 cP on its pour point at 51 oC to 134.24 cP at 90 oC. From the microwave heating, it is also known that the heating rate is directly proportional to output power and nano ferro concentration. The increase of temperatures also affected the recovery factor at 51 oC, 60 oC, 70 oC, 80 oC, and 90 oC, respectively the recovery factor are 0%, 28.55%, 34.07%, 35.32%, and 36.08%.
