Exploitation of extra heavy oil resource will be the main R & D challenge in the future. In India Mehsana oil field is the one of the extra heavy oil belts. In such type of fields advanced EOR is of primary concern to increase the recovery. Apart from conventional thermal methods this paper discusses about the commercialization and broad application of (MWAGD) as alternative thermal method in the Mehsana oil field. In this study, applicability of microwave heating for heavy oil from Mehsana heavy oil field was experimented and analyzed quantitatively. In this paper a core sample of Mehsana field is taken and heated with the microwave energy provided by a microwave source consisting of magnetron tubes to generate the microwave power. Micro-Wave radiation is non-ionizing so requires high frequency current (3000 MHz) which causes friction by vibration of molecules which results in dielectric heating of the sample. In this experiment heat transfer between microwave source and core is described quantitatively. Temperature and viscosity profile of the gravity drained oil are observed graphically and analytically. Effects of initial oil and water saturations, wettability, porosity, permeability are discussed with respect to the drained oil. Economic evaluation is also done by comparing the costs in USD/barrel between the above proposed method and the method which is being run presently i.e. Steam Assisted Gravity Drainage (SAGD). In this paper authors have also shown the work-how of applicability of MWAGD in the Mehsana field in present scenario. MWAGD is cost effective than the conventional EOR methods. It is also more efficient and less time consuming as there is speedy heat transfer by dielectric heating. MWAGD does not cause any consequential damage and provides greater oil displacement efficiencies. Also, the heavy deposit of residual coke or carbon is rooted out.
