| | | Technology and Innovation | |  | As the exploration and development of oil and gas proceed, there are fewer oil and gas resources that are easy to discover and tap, and the produced petroleum is becoming more inferior. To satisfy ever increasing energy demand and meet higher environmental protection standards, our technical innovation is focused on increasing the exploration success ratio of complex oil and gas reservoirs, enhancing the recovery |
| efficiency of mature oilfields, developing unconventional hydrocarbon resources, improving the quality of refined and chemical products, and ensuring clean operation.
We have 76 scientific research institutions with 28,486 scientific research personnel. Our annual R&D investment has exceeded RMB 4 billion in recent years. We have established various long-term partnerships with CAS (Chinese Academy of Sciences), universities and research organizations. We also continuously enhance technical communication with our international counterparts, jointly facing challenges in the development and utilization of oil and gas as well as environmental protection. | | | | |
