This paper discusses the successful application of managed-pressure drilling (MPD) in the basin with reduction in risks and well costs. In recent years, approximately 27% of major oil and gas discoveries have come from HP/HT fields. The South China YQ Basin is one of the three major offshore HP/HT regions in the world and is located at the intersection of the Eurasian, Pacific, and Indo-Australian plates and has a complex geological structure.
