| | | R&D Progress | |  | CNPC's major research and development progresses, evaluated and chosen by our research institutions and experts every year, represent our annual remarkable achievements in major scientific and technological projects and progresses in technology integration and application, in terms of oil & gas exploration, development and production, refining and chemical, engineering and construction, and equipment manufacturing. |
| | | | All these reflect the improvement of CNPC's core competitiveness and independent innovation, and provide enhanced technical support to sustained and coordinated growth of the company. | | | In 2010, our theoretical innovations and technical breakthroughs overcame key technological bottlenecks that had constrained our business growth, and led to remarkable application results. These included the exploration of conventional and unconventional oil and gas such as exploration for metamorphic basement rocks and high-coal-rank CBM; production stabilization and water cut control in mature oilfields and the thermal recovery of ultra-heavy oil in the field of development; and seismic data processing, horizontal drilling, completion, and staged fracturing, and logging processing and interpretation in oilfield services; as well as efficient and safe blending transportation of multiple types of crude in long-distance pipelines and FCC gasoline hydro-upgrading. | | | | | | | | | | |
