In December 2003, CNPC signed an agreement with the Swiss company Cliveden to buy shares for the risk exploration of Block H in Chad. Block H covers the whole or partial area of seven depositional basins - Chad Lake, Madiago, Bongor, Doba, Doseo, Salamat and Erdis.
In 2005, we proved the existence of three groups of reservoirs: the top group, middle group and bottom group. In 2006, CNPC obtained all the equity of Block H, and discovered new oil-bearing structures including Baobab and Ronier-1 in the Bongor Basin of the block .Well Ronier-1, the exploration well located in the Ronier-1 structure, encountered three sets of oil and gas formations of different grades, producing conventional crude oil for the first time.
In 2009, progressive exploration in Ronier and Mimosa areas in the Bongor Basin resulted in the discovery of new reserves. Significant progress was also made in the exploration of Prosopis and Baobab.
In 2010, we made key exploration discoveries in Bongor Basin, and achieved successful formation test in risk exploration well Cassia N-1 deployed in the Naramay area of Block H, which yielded a 1,000 tons per day oil flow.
N'Djamena refinery
On Sept. 20, 2007, CNPC and the Chadian Ministry of Petroleum signed an agreement for the establishment of a joint venture refinery. In 2008, the foundation was laid for N'Djamena JV refinery, which is 60% owned by CNPC and 40% owned by the Chadian Ministry of Petroleum. Expected to process 2.5 million tons of crude oil per year, the JV will be Chad's first refinery when it is completed and made operational in 2011. |

In 2007, CNPC and the Chadian Ministry of Petroleum signed an agreement for the establishment of a joint venture refinery company. The refinery, jointly invested by China and Chad, is located to the north of N'Djamena, the capital of Chad. CNPCI is in charge of all engineering construction, and Chinese design specification, manufacturing standard and machinery shall be adopted.
In 2009, construction of the integrated upstream-downstream project started. The crude pipeline from Ronier to N’Djamena is 311 kilometers long, and the designed annual deliverability is 1 million metric tons in the first phase. To lay the pipeline, horizontal directional drilling was used to cross the Chari River, which minimized its impact on the river and the valley, and is an example of our responsible attitude toward the environment. The main part of the crude pipeline from Ronier to N'Djamena was completed by the end of 2010.
