Plenty of extra-heavy oil reservoirs have been found and yet it is challenging to exploit due to high viscosity of extra heavy oil. Thermal injection is required to exploit that extra heavy oil. Electrical heating, one of thermal injection method, is capable to enhace extra heavy oil recovery. <br /> <br /> On the last decade several thermal mechanisms have been studied to increase the recovery of extra heavy oil reservoir. In this study, thermal mechanism was focused on bottom-hole electrical heating. Referred to mentioned reservoir, the efficiency of electrical heating was evaluated based on heating time and correlated to enhanced oil recovery. This study was carried out by numerical simulation, analysing the most influential parameters through an experimental matrix of 26 cases run in a horizontal well of 2000 feet. The property of fluid is extra-heavy oil with 12.3 oAPI. This 100 ft thick reservoir was heated by electrical thermal heating downhole tool which has 300oF maximum heating temperature. Temperature and oil saturation changes were analysed. Lastly, determining number of horizontal well as either heater or producer well affected the payback time. <br /> <br /> Using Computer Modeling Group STARS simulation, the increase of well bore temperature affected fluid property around the well bore. Shut-in time is unnecessary for ‘single well’ whereas required for ‘double well’. To sum up, one horizontal well which worked as heater and producer provided the most efficient for it produced high recovery factor whilst expended the lowest cost. Thus, the payback would be the shortest
