A Precious Achievements Review of Geological Development and IOR Application From 20 Sucessful Years in High Temperature Fractured Granite Reservoir

Abstract

Natural fractured petroleum reservoirs represent over 20% of the world’s oil and gas reserves. It plays an obvious role in oil exploration and makes a large contribution toward oil and gas production worldwide. The research tendency for natural fractured reservoir NFR has become more apparent in the last five to ten years because more fractured reservoirs are being developed as production from conventional reservoirs is declining. However, characterization of fractured reservoir is complex and presents unique challenges in comparison with conventional reservoir. There are several uncertainties in NFR characterization in exploration and field development strategies, especially in the early stages when little or even no data is available. Thus, it is urgent and necessary to collect the experiences from previous successful research to reduce risky level in such reservoir.
