Steam Flooding is Feasible and Capable to Enhance Oil Production in SaBei Transition-Zone

The use of steamflooding as a tertiary recovery method for light-oil reservoirs after waterflood has been of interest in recent years. Although steamflooding applied to heavy-oil reservoirs has been a fully proven method, the technology of applying it to light-oil reservoirs, especially those that have been watered out,is still in its infancy. This paper presents a comprehensive simulation study on the use of steamflooding after waterflood in light-oil reservoirs, to analyze the recovery mechanisms and the conditions which will be suitable for steamflooding. Compared to the actual oil properties and reservoir characteristics in SaBei Transition-Zone in Daqing oil-field, it has been proved the feasibility of steamflooding in this area. This study will be beneficial for the enhancing recovery, especially for the whole Transition-Zone area in Daqing oil-field. It will provide the technical reference and guidelines as well.
