ISC Application in Heavy Oil Reservoir after CSS
In order to improve the flowability of crude oil, heavy oil reservoir usually developed by steam injection. While this process produces a lot of greenhouse gases. To deep reservoir, heat loss in the wellbore tends to more severe and thermal efficiency is lower. In-situ Combustion (ISC) is featured by heavy components’ combustion, high thermal efficiency and high oil recovery. Those advantages are outstanding especially in the aspects of improving thermal efficiency and reducing greenhouse gas emissions. This paper researched on ISC EOR process in a complex fault block, including reservoir design and performance evaluation. Remarkable development results have been achieved, which shows the potential for ISC technology and this paper provides a reference for the development of similar reservoirs.
