CNPC in Chad

CNPC got involved in Chad's oil and gas businesses in 2003. Now we have all the equity of Block H and a 60% share of N'Djamena JV refinery, while also providing oilfield services.

Block H

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. 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 important 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.

In 2011, a hydrocarbon play was discovered at Block H in the Bongor Basin. In 2012, we discovered the oil-rich Lanea block in the Bongor Basin and made important progress in lithologic reservoir exploration in Raphia region. In 2013, we made significant discoveries from risk exploration in the Bongo Basin, obtaining high-yield flows from the thick oil reservoirs in buried hills.

In 2014, an oil reserve of 100 million tons was identified in the buried hill reservoirs of the Bongor Basin. We enhanced study on reservoir geology and optimized stimulating operations, achieving an equity production of 2.6 million tons in 2015.

In 2016, a number of new oil reservoirs were discovered in the buried hill rocks.

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. N'Djamena JV Refinery is the second refinery that CNPC has ever designed and built overseas. Its main products include gasoline, diesel, fuel oil, LPG, and PP. Its associated power station supplies electricity to the capital city of Chad. In 2011, the upstream and downstream integrated project was completed and put into operation. On July 10, 2011, its first batch of diesel products was delivered to the local market. 2012 witnessed the first full year of the operation of our upstream-downstream integrated projects in Chad, which achieved excellent performance in oilfield production, pipeline operation, and crude refining. The N'Djamena JV Refinery smoothly fulfilled its operating objectives, and produced diesel, gasoline, and LPG products meeting local market demand. The refinery was overhauled and fulfilled the annual production target in 2014, and achieved safe, steady and efficient operation with optimized processes and production plans in 2015.

CNPC provides a range of oilfield services in Chad, including geophysical prospecting, well drilling and logging, as well as engineering and construction. We have provided seismic data acquisition service for EnCana's project in Chad.

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.

In 2013, we won the contract for the 3D seismic project for CPC Taiwan in Chad.

Environmental Protection

In the development of the Ronier Oilfield, CNPC strictly observed the “Environmental Law of Chad” and the “Environmental Evaluation and Study Report of Operating Blocks”. Before operation was carried out on any new block, we appointed dedicated organizations to investigate the protected trees, wild animals and plants, cultural relics, and historic sites in it. In doing this, we minimized environmental impact and ensured clean production. Before a well was spudded, water, soil, and atmosphere samples were taken and analyzed. After drilling, the environment was sampled once again for comparative analysis. After one or two rain seasons, the vegetation on the well site has been restored.

In 2013, we immediately initiated the emergency response system after a mud pit pollution accident, and cleaned up residual oil and restored the ecological environment at the well site. We also hired a professional environmental protection company to continuously monitor well-site soil and groundwater. In the meantime, we looked into the management process and responsibility implementation, and amended our environmental protection regulations according to Chad’s laws and international standards, in order to avoid the reoccurrence of similar environmental pollution accidents.

Training and Education

In 2012, N'Djamena Refinery recruited more than 120 local employees to work in major production posts. Since its startup in 2011, the refinery has launched training programs on the English language, refining and chemical knowledge, management, and HSE. Local employees have mastered refining and chemical know-how with the help of Chinese employees as their personal coaches. To help cultivate future talents for the development of Chad's refining industry, the refinery reconstructed its temporary premises into a campus for the petrochemical department of a local petroleum college, and provides interim and training opportunities to students majoring in refining and chemicals. The campus includes two academic buildings, where 100 students can receive lectures at the same time. According to Mr. Makaye Hassane Taisso, Chad's Education Minister, the opening of the petrochemical department at the refinery will provide the students with a better and more practical educational environment and some of the students may start their career at this refinery.

Social Welfare and Community Development

In 2011, the Alkoudou primary school funded by N'Djamena refinery was put into use and the students have received schoolbags, stationery and sports equipment from the joint venture. In 2012, we donated more than RMB 600,000 to help flood-stricken people. In 2013, our N'Djamena Refinery has become a cooperative partner of the SOS Children's Villages. During the Ebola outbreak in 2014, we invited Chinese disease control experts to provide our employees in Chad, with necessary prevention knowledge and measures to counter this highly contagious disease.

In 2015, we launched the community resource assessment project in Chad, and built 24 water wells providing 22,113 residents in 21 nearby villages with drinking water.

Jun. 29, 2011 N'djamena Refinery was completed and went on stream, marking the full operation of the first phase of Chad's upstream and downstream integrated project.

July 01, 2009 The oilfield surface engineering and pipeline construction of a CNPC's upstream project commences in south Chad.

Oct. 26, 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.

Sept. 20, 2007 CNPC and the Chadian Ministry of Petroleum signed an agreement for the establishment of a joint venture refinery.

2006 CNPC acquired all the equity of Block H in Chad via capital and share expansion.

Dec. 18, 2003 CNPC signed an agreement with Swiss's Cliveden company to buy its shares for the risk exploration of Block H in Chad.
