The first phase of the upstream and downstream integrated project includes the construction of the 1Mt/a Ronier Oilfield, the 1Mt/a N'Djamena Refinery, and a 311km-long crude pipeline between the oilfield and the refinery. The pipeline is the first energy passage connecting north and south of Chad. N'djamena Refinery is the largest joint venture and industrial enterprise in Chad, also the second largest refinery built by CNPC overseas, mainly producing gasoline, diesel, fuel oil, LNG and polypropylene. The refinery's first batch of diesel was loaded for sale on July 10.

CNPC took over H Block officially in January 2007, and completed surface engineering and pipeline construction in only 4 and a half year despite poor local safety situation and harsh conditions. The project became operational on schedule and created a 45 million man-hours safety record.

● On December 18, 2003, CNPC signed an equity purchase agreement with Swiss company Cliveden on risk exploration of Chad's Block H.

● In 2006, CNPC acquired 100% equity of Block H.

● On September 20, 2007, CNPC signed an agreement with Petroleum Ministry of Chad to jointly build a refinery.

● On October 26, 2008, N'Djamena Refinery, jointly invested by CNPC and Chadian government, laid foundation in Chad's capital. The refinery has a designed annual processing capacity of 2.5 Mt/z and is planned to be operational at the end of 2011.

During project construction, great attention was given to biological diversity protection and recovery. As required by Chadian Environmental Law and Environmental Evaluation Report in Operating Zone, specialized agencies were employed to do research on environmental sensitive factors in the working zone such as protected tree species, wild animals and plants, and historical heritages, so as to mitigate the influence of construction. Before drilling, water, soil and atmospheric samples were collected for analysis. During drilling, content of nine minerals including petro factors, zinc and lead were strictly monitored. After drilling operation completed, re-sampling was made for comparison analysis.

Waste disposal site was set up to recover sludge, used batteries and other wastes. Through incineration, natural degradation and reutilization, the impact to the environment has been minimized. After one or two rainy seasons, the areas where drillings were completed witnessed recovered plants and returned animals.

Since elephants frequent some construction sites, to protect their daily habit from disturbance, the project team decided to build the pipeline during the intervals between the morning and evening drinking time of the elephants, and quietly evacuate all equipments and staff after construction and soil refilling.

The project team has established good relationships with surrounding communities and actively involved in public welfare endeavors by donating school bags for students living at remote areas and repairing wells for local villages. On Children's Day in 2011, the Alkoudou primary school built with the assistance of CNPC opened and received stationeries and sports goods donated by the team.

Chadian President Idriss Deby: June 29, 2011 is historically significant for Chadian people as we won the victory of energy independence battle. This should be attributed to China's cooperation.

Chadian Minister of Petroleum Tabe Eugene: The operation of N'Djamena Refinery enables Chadian people to consume locally refined oil products and enjoy the added value of locally processed crude. It would also promote the development of Chad's petroleum and petrochemical industry, provide more jobs for young people, ensure national energy independence and make contributions to national economic and social development.
