 marine phase gas field discovered in China to date. 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. Sinopec Corp. has prepared and filed with the relevant state
 department an exploration plan. The State has approved Sinopec Corp. to start

Sinopec Corp. announces that it has discovered Puguang Gas Field in the
northeast region of Sichuan Province which is the largest and most abundant
marine phase gas field discovered in China to date. 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.

                                                 By Order of the Board
