The transportation of heavy oil is always the matter of concern for oil industries. The viscosity of heavy oil ranges from 200 CP (centipoise) to 5,000 CP and is strict function of composition of hydrocarbons. Due to high viscosity, the mobility of heavy crude is very low at reservoir conditions. Moreover, it is very difficult to flow heavy crude at cold temperatures from offshore regions to the refinery. Therefore, despite in the improvements in thermal recovery methods such as Toe to Heel Air Injection (THAI), Steam assisted Gravity Drainage (SAGD), Steam Injections, etc., some diluents like C4+ and hydrocarbon gases are introduced with it. Recently, the team of researchers under Rongjia Tao, a physicist at Temple University in Philadelphia, has found an alternative way to transport heavy crude by applying electric and magnetic impulses. Magnetic impulses are basically more effective for paraffin based crude oil and its effect lasts for 8 to 10 hours after the implementation of strong magnetic field. This technical paper aims at analyzing Mr. Tao’s experiment, rectifying its limitations and proposing a better experimental setup for the pilot experiment so that it can be further extrapolated to the industrial point of application.
