Abstract: Thermal heavy oil recovery case study showed that there is better linear relation between lg2Np and lglgQS,lgLPNp and lg2QS during the certain stage of thermal heavy oil recovery, where Np is cumulative oil production, Lp is cumulative liquid production, and QS is cumulative steam injection.On the basis of these linear relations, the formula can be derived to calculate each development index and to predict thermal heavy oil performance.
