According to the evaluation by the Mineral Resources Reserves Assessment Center of the State Ministry of Land and Resources, by the end of 2005, the aggregate proved recoverable reserve of Puguang Gas Field amounted to 251.075 billion cubic metres and the technical recoverable reserve amounted to 188.304 billion cubic metres. Currently, Puguang Gas Field is also one of the five largest gas fields discovered in China with reserves over 200 billion cubic metres. According to the assessment results, Puguang Gas Field already meets the requirements for commercial development. Sinopec Corp. has prepared a proposal for the Phase I development and submitted the same to the relevant department of State. According to the proposal, commercial gas production of more than 4 billion cubic metres per annum will be realized by 2008 and commercial gas production of 8 billion cubic metres per annum will be realized by 2010. A natural gas pipeline will be constructed from the northeast region of Sichuan Province to Jinan in Shandong Province. The State has issued an approval for Sinopec Corp. to start preparation activities for this project. The discovery of Puguang Gas Field is a result of innovations in marine phase exploration theory, philosophy, technology and management regime, and has proved to be a significant breakthrough in China's marine phase exploration theory and practice, and to have expanded the range of exploration for Sinopec Corp.'s in the field of natural gas. Sinopec Corp. has prepared a strategic exploration plan setting the southern marine phase structure as the main target, to expedite exploration in Sichuan Basin and its surrounding areas and seeking further development and breakthroughs. At present, Sinopec Corp. has 12 exploration blocks in Sichuan Basin and its surrounding areas with an exploration area of 100,000 square kilometres and this has laid a solid foundation for Sinopec Corp.'s long-term objective of natural gas exploration in the southern region. Under the guidance of new theories, Sinopec Corp. has prepared medium and long-term strategic plans to expedite natural gas exploration and development in Sichuan Basin and its surrounding areas. Development of natural gas, construction of gas pipelines and sales and marketing of natural gas will be launched at the same time. We will announce in a timely fashion all information regarding material developments to this project.
