World's energy challenges would be greatly improved upon if half of the world's heavy oil and extra heavy oil could be made to ow in pipelines. Viscosity reduction of heavy oils is the key to solving this problem. In this study, aside from injecting pure nitrogen and pure carbon dioxide separately into the oil, two different compositions of the mixture of the two gases were also injected. In the first mixture, varied quantities of the two gases were used; 62:5%, 82:2% and 86:4% of the mixture was nitrogen while 37:5%, 17:8% and 13:6% was carbon dioxide at total test pressures …
