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

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