Steam Assisted Gravity Drainage in Heavy Oil Reservoirs

چکیده مقاله

Heavy oil and tar sands are important energy sources , currently making a significant contribution to the overall energy of the United States and Canada . It is evident that the resource base is much larger than the in-place “conventional” oil which is about 2 trillion barrels worldwide , with about a third recoverable . In the case of heavy oil and tar sand , the recovery factor varies greatly from area to area , depending on the oil and the reservoir characteristics , as well as the process to be used . In this article investigated effect of some parameters such as initial reservoir pressure , initial reservoir temperature , molecular weight of components , energy in rock , water and oil on single horizontal well SAGD process .
