.... The dead oil viscosity is 230,000 mPa.s at 50 °C. Although Cyclic Steam Stimulation (CSS) process using vertical wells has been applied successfully in producing oil from the reservoir, the anticipated ultimate oil recovery is less than 29% of the original oil in place (OOIP). To enhance oil recovery...

... Abstract Xing VI formation in the Shuguang area of Liaohe Oilfield contains 60–80 metres of low API bitumen (<10 ° API), which is buried at a depth of 750–800 metres. Cyclic Steam Stimulation (CSS) process has been applied successfully using vertical wells since 1997. A recovery factor...
