In Kazakhstan, CNPC mainly operates five oilfield development projects (CNPC AktobeMunaiGas, North Buzachi, PK, KAM and ADM), two exploration projects, the Kazakhstan-China Crude Oil Pipeline and the Northwest Crude Pipeline, while also constructing the Second Phase of the Kazakhstan-China Gas Pipeline, etc.

CNPC AktobeMunaiGas

In June 1997, CNPC acquired a 60.3% stake in AktobeMunaiGas, and obtained the production license for the Zhanazhol, Kenkiyak Oversalt and Kenkiyak Subsalt oilfields and a contract for an exploration block. CNPC now owns an 85.42% shareholding in AktobeMunaiGas.

In 2011, AktobeMunaiGas was reputed by our partner – KazMunaiGas – as a model of Kazakhstan-China oil and gas cooperation, with the recovery efficiency of its Kenkijak Subsalt Oilfield further increased and the oil production of its MMG Oilfield recording a new high. CNPC and KazMunaiGas concluded an in-principle cooperation agreement to jointly explore and develop Urikhtau Gas Field, which will be a gas source to Phase-II Kazakhstan-China Gas Pipeline.

Kenkiyak Subsalt Reservoir

Since CNPC's takeover of AktobeMunaiGas, by utilizing advanced drilling techniques and rich development experience, CNPC made it possible to tap the more than a hundred million tons of reserves in Kenkiyak subsalt reservoirs that are difficult to access.

Zhanazhol Oilfield

The Zhanazhol Oilfield has been developed for almost 30 years. By applying gas lift technology, CNPC shortened the flowing back cycle and the production cycle, and increased the average daily production per individual well by 18.8 metric tons. Gas lifting is currently applied to more than 250 oil wells in Zhanazhol Oilfield, and the daily output of gas lift wells accounts for more than 67% of the total in the whole field.

Central Block at the Eastern Edge of the Precaspian Basin

In June 2002, CNPC signed a risk exploration contract on the central block at the eastern edge of the Precaspian Basin with Kazakhstan's Ministry of Energy and Mineral Resources. The block is located in southern Aktobe, covering an exploration area of 3,262.3 square kilometers, with a contract term of six years.

In 2005, high-yield oil flows were obtained from exploration well A-1 located on Block A. The preliminary output was tested up to 85 metric tons of crude per day. In 2007, high-yield oil flows were obtained from the major oil formations in five exploration wells in the North Troyes structure of the central block in the Precaspian Basin. Oil in place was estimated to be 150 million metric tons. By the end of 2008, 180 million metric tons of oil in place was proved at Umit Oilfield.

In 2009, a number of exploration wells at Kazakhstan's Pre-Caspian central block also resulted in new breakthroughs, further expanding the oil-bearing area of the Hope Oilfield, the joint oil/gas project in Aktobe.

In 2010, new geologic discoveries in the Pre-Caspian central block consolidated and expanded the resource foundation of the Hope Oilfield.

In 2011, the No. 4 Oil and Gas Processing Plant at the Hope Oilfield in Kazakhstan was completed.

In 2012, CNPC-International Aktobe’s exploration activities in the peripheral Hope Oilfield enlarged the oil-bearing area of the field, and PetroKazakhstan obtained commercial discoveries from a number of exploration wells.


CNPC acquired PetroKazakhstan in October 2005. According to an agreement with Kazakhstan's Ministry of Energy and Mineral Resources, CNPC transferred 33% of its shares in PetroKazakhstan to KazMunaiGaz in July 2006, and retained the remaining 67% stake in the company.

PetroKazakhstan is an integrated international energy company with upstream and downstream operations covering oil and gas exploration, development, refining and marketing of refined products. It now has 11 oilfields and 5 exploration blocks. The upstream assets are located in the South Turgai Basin, and the downstream business line generally includes the refining and marketing of refined products and crude oil. PetroKazakhstan owns the Shymkent refinery, the largest in Kazakhstan, and a transportation and sales network consisting of sales companies and service stations in Cyprus and Kazakhstan.

Since taking over PetroKazakhstan, CNPC has made exploration breakthroughs and oil and gas discoveries in both mature and new fields. In December 2006, well Aryskum-27 was completed with good oil and gas shows being observed during the drilling, indicating favorable exploration prospects in deep zones in this region. By rebuilding the oil formations and controlling the total water cut, CNPC kept PetroKazakhstan's crude oil output above 10 million for two consecutive years.

In 2008, PetroKazakhstan discovered massive reservoirs in carbonate buried hills, and obtained commercial oil and gas flows at Block Doshan in the west, as well as the little-explored Block Karaganda in the north.

In 2010, we made important breakthroughs in progressive exploration of two blocks and two mature oilfields in South Turgai Basin as part of PetroKazakhstan, with oil and gas discovered above the caprock of the region for the first time. These demonstrated new room for exploration to tap into unstructured reservoirs.

North Buzachi Oilfield

North Buzachi Oilfield is located in Mangghystaū, western Kazakhstan. In 2003, CNPC purchased 35% and 65% shares of Chevron Texaco North Buzachi Inc. (TNBI) from Nimir and Texaco respectively, and thereby owned a 100% stake in the North Buzachi Oilfield. CNPC and Russia's Lukoil currently have 50% holdings each in the North Buzachi Oilfield after the stock rights changed hands several times. The oilfield is jointly operated by the two companies.

In 2005, CNPC's horizontal sidetrack drilling and acidizing-based stimulation test in the North Buzachi Oilfield both obtained excellent results. Output from the horizontal sidetrack wells was as much as 14.4 times of the previous output, while the output from acidized wells was increased 3.6 times.

On July 10, 2009, the phase-Ⅱ engineering of the North Buzachi central processing station started operations, which raised the oilfield's processing capacity to 2 million metric tons a year.

KAM Project

The KAM project mainly includes Konys and Bektas oilfields, which are located in the South Turgai Basin, covering an area of 431 square kilometers.

In November 2004, CNPC acquired 50% shares in Konys and Bektas oilfields (KAM Project). The company currently owns a 25% holding in the two oilfields respectively.

ADM Project

In January 2005, CNPC signed an agreement with Ay-Dan to buy shares for ADM and acquired a 100% stake in it. Ay-Dan has exploration licenses for the Aryss and Blinov blocks. The licensed exploration areas are 215.86 square kilometers and 59.697 square kilometers respectively.

In 2006, oil and gas flows were obtained from Cretaceous formations in appraisal well SPR5 in the northern lakeshore No.3 structure, with a daily output of 122 cubic meters. In 2007, commercial oil flows were discovered in South Aryss and Blinow, increasing the oil in place by 12 million metric tons. In 2008, we made several new discoveries in carbonate reservoirs in the lakeshore prospect area.

Jointly Operated Piplines

Kazakhstan-China Crude Oil Pipeline

Kazakhstan-China Gas Pipeline

Kenkiyak-Atyrau Pipeline

Zhanazhol-KC13 Gas Pipeline

CNPC provides oilfield services in Kazakhstan, including geophysical prospecting, well drilling, logging and testing.

In 2008, we entered the market in Aktobe, Aqtau, Atirau and Kezloerda, winning contracts for the CITIC well logging and SAGIZ well logging and perforation projects.

Drilling of Kenkiyak subsalt reservoir

Kazakhstan's Kenkiyak subsalt reservoir presents some of the most difficult drilling conditions in the world, including deep buried reservoir, high pressure and complicated formation section. Drilling in this area has had an extremely low success rate. However, drilling experts and technicians from CNPC successfully penetrated a 3,000 meter thick, gas-bearing halite formation by utilizing zwitter-ion polysulfante saturated saline drilling fluid to prevent the dissolution of halite strata, and adding anti-sloughing and anti-sticking agents to prevent reservoir destabilization and collapse. They achieved a 100% drilling success rate.

Kazakhstan-China Oil Pipeline

The Kazakhstan-China Oil Pipeline (Atasu-Alashankou), Kazakhstan's first pipeline directly connected to the market without passing through any third country, was completed in December 2005 and put into commercial operation in July 2006. The construction of the Atasu-Alashankou section has traveled through a marsh for 34 kilometers, a desert area for 150 kilometers and a bold windy area for 83 kilometers, and also crossed four rivers, nine highways and two railways.

CNPC and KazMunaiGaz signed an agreement on the construction and operation of the Phase II Kazakhstan-China Oil Pipeline in August 2007, and its construction was started in December 2007.

In December 2008, the main part of the Phase II Kazakhstan-China Oil Pipeline (Kenkiyak-Kumkol) was welded and became operational in October 2009.

Central Asia-China Gas Pipeline

The Central Asia-China Gas Pipeline is the first long-distance gas pipeline that we built and operate that traverses several foreign countries. This 3,666km-long pipeline consists of Line A and B installed in parallel to each other, starting at Turkmen-Uzbek border city Gedaim, running through Uzbekistan and Kazakhstan, and reaching Horgos in China's Xinjiang Uygur Autonomous region. Line A was completed and became operational on December 14, 2009.

Construction began on the Kazakhstan segment of the Central Asia-China Gas Pipeline in July 2008. On December 12, 2009, 1300km-long Kazakhstan-China Gas Pipeline was completed. JV Asia Gas Pipeline LLP (AGP) is in charge of the construction and operation of the Kazakh section of Central Asia-China Gas Pipeline.

After Line B and Compressor Station 4 in Kazakhstan were completed on October 26 and December 14, 2010, respectively, the delivery capacity of the pipeline was upgraded to 15 bcm/a.

The Central Asia-China Gas Pipeline has maintained safe and steady operation since the startup of its Line A and Line B in October, 2010. In 2011, No.1, 4, and 6 compressor stations were completed and put into operation, upgrading the deliverability of the pipeline to 23bcm/a. The pipeline transported 15.86 billion cubic meters of gas throughout the year. In addition, CNPC signed agreements with Uzbekneftegaz and KazMunaiGas to build and operate Line C of the Central Asia-China Gas Pipeline, which will run in parallel to the operating Line A and B to transport gas from Turkmenistan, Uzbekistan, and Kazakhstan. After Line C is completed, the deliverability of the pipeline will be upgraded to 55bcm/a.

With No.7 and No.2 compressor stations being operational, the Central Asia-China Gas Pipeline had its deliverability boosted to 30bcm per year. By the end of 2012, the pipeline had transported more than 44 billion cubic meters of natural gas. Construction of its Line C has already commenced, which will run in parallel to Line A and Line B. Completion of Line C will further boost the pipeline’s deliverability to 55bcm per year.

The Second Phase of the Kazakhstan-China Gas Pipeline

The Kazakhstan-China Gas Pipeline, an important part of the Central Asia-China Gas Pipeline, will be built in two phases. The 1,300km-long Phase 1 is the section of the Central Asia-China Gas Pipeline through Kazakhstan, and was completed and put into service in December, 2009. The second phase starts from Beyneu of Mangystau Province in Kazakhstan, and will be connected to the Central Asia-China Gas Pipeline at Shymkent of South Kazakhstan Province. This 1,475km-long section is designed to transport 10 billion cubic meters of natural gas a year, and has a potential of up to 15 bcm/a, thus meeting the gas demand in southern Kazakhstan.

Construction of the second phase began on December 21, 2010. A 1,164km-long section from Bozoy of Aktobe Province to Shymkent will be built to have a capacity of 6 bcm/a, and is planned to be put into service at the end of 2012. At the second stage, a 311km-long section from Beyneu to Bozoy will be installed, upgrading the capacity to 10-15 bcm/a.

Additionally, CNPC has completed the construction of a range of major projects in the country.

A 44km-long pipeline for combined transportation of oil and gas from Zhanazhol oilfield to Kenkiyak was built in April 2005.

The first phase of the Third Zhanazhol Oil & Gas Processing Plant was completed and become operational in December 2007, became Kazakhstan's first project to achieve the 100% recovery of a large amount of associated gases.

PetroKazakhstan's Comprehensive Natural Gas Utilization Project (Phase I) became operational in April 2008, reducing the burnt-out quantity of associated gases from 97 million cubic meters in 2007 to 46 million cubic meters.

Environmental protection

CNPC gives priority to protecting ecological environment and improving the efficiency of natural resource utilization. Moreover, we have actively promoted the use of environmentally friendly technologies and taken various measures in order to minimize our environmental footprint. Our efforts include improving energy efficiency, resource recycling, ecological restoration, and emissions reduction.

All of CNPC's projects in Kazakhstan - whether for exploration or development, refining or petrochemicals, pipeline transportation or technical services are required to make an Environmental Impact Assessment (EIA) before, during and after construction, in order to avoid negative impact to local environment. At the same time, we are committed to saving water resources and reducing wastewater discharges. Liquid and solid wastes and domestic sewage are sorted and treated at separate treatment plants.

In response to the Kazakh government's prohibition on gas flaring, we have made efficient use of oilfield associated gas and achieved significant economic, environmental and social benefits. Our oil and gas processing capability has been enhanced, resulting in increase of output. The recovered associated gas is used for power generation to improve energy efficiency. The remaining associated gas is re-injected to the reservoirs to minimize environmental pollution.

During the construction of the Kazakhstan-China Oil Pipeline, we placed a high premium on the protection of soil, vegetation, and wild animals, as well as the restoration of landforms. Among our many efforts, we avoided building camps and limited construction area. We also tried, whenever possible, not to occupy farmland and other fertile areas. Action was immediately taken to remedy any damage caused. While digging pipe ditches, we were certain to return the topsoil to its correct place.

During construction, employees were forbidden from lighting fires in the vicinity of weeds and shrubbery in order to minimize the impact on wild animals'habitats. When digging the pipe ditch, we created a temporary passage for animals so that their natural movements to and from water sources would be unimpeded. And after completion of the project, we tried our best to restore the land to its original characteristics.

In 2009, PetroKazakhstan Inc., a holding company of CNPC, adheres strictly to the environment laws and rules of Kazakhstan and actively responds to the call of the local government for comprehensive utilization of natural gas. The company strengthened the development of projects involved in the comprehensive use of natural gas. The second phase of the PKKR project and the TP oil/gas processing plant has been completed and made operational. Over 90% of the company's natural gas is comprehensively utilized, taking the lead among companies in Kazakhstan. In October 2009, PK was granted the highest honor in environmental protection in the oil industry - Golden Prometheus - by the government of Kazakhstan in recognition of its efforts in the comprehensive utilization of natural gas and its achievements in environmental protection.

In 2010, we invested USD 350 million in three major natural gas utilization projects — the oil transfer station of Hope Oilfield, No. 4 Oil and Gas Processing Plant, and wet gas re-injection. The three projects were built and became operational within only eight months. CNPC-AktobeMunayGas was therefore granted the "Golden Award of Most Socially Responsible Enterprise" by Nursultan Abishevich Nazarbayev, President of Kazakhstan.

Economic Development

CNPC promotes local economic development through supplying natural gas to local people and companies at a preferential price, as well as crude oil to Kazakh refineries and agricultural oil to farmers at a reduced price. Currently, we supply natural gas to residents and industrial enterprises in Aktobe at a 75% discount. Meanwhile, CNPC supplied more than 3.4 million metric tons of crude oil at the domestic rate to Kazakh refineries between 2001 and 2008.

We also seek to stimulate the development of Kazakhstan's small-and medium-sized enterprises through the purchase of local goods and services. In 2006, CNPC AktobeMunaiGas purchased goods and services worth USD 719 million from Kazakh suppliers, which were mainly small-and medium-sized enterprises. During the construction of the first section of the Kazakhstan-China Oil Pipeline, our purchases from Kazakh companies, such as locally produced raw materials and mechanical equipment, were worth more than USD 17 million. The supply of concrete, sand, rocks, steel, and LNC used for welding was ll sub-contracted to local companies with a contract value of USD 19.3367 million. We also sub-contracted projects worth USD 18.6 million to local contractors, which directly and indirectly created 1,500 jobs.

Our sustained development in Kazakhstan has promoted the construction of local infrastructure. The Emba-Zhanazhol Railway, invested and constructed by CNPC, became operational in December 2006. With a designed freight capacity of 2.262 million metric tons per year and passenger capacity of 6,000 people per month, the 79.7 kilometers railway is free for our employees and can satisfy the needs for production and living. It has also made it easier for farmers along the line to reach new markets.

In 2007, CNPC donated USD 4 million and USD 1.8 million to Kyzylorda Province and South Kazakhstan Province respectively, funding the construction of railway, community park, school and library, and helping local residents to improve drinking water and power supply facilities.

In 2010, we provided support to five agricultural areas, and funded the repair and maintenance of community kindergartens in Mangystau Province.

Training and Education

CNPC is committed to staff career planning, and to this end provides training and education opportunities to all employees. The education and training programs are well-thought out and based on the needs of career planning. We have long-term cooperative ties with reputable universities, colleges and specialized training agencies in Kazakhstan and foreign countries, providing training in technology, management, sales, HSE, quality supervision, business and foreign languages.

We have been holding a three-week management training for Kazakh managers at a training center of the China University of Petroleum (Beijing) for many years so that local managers can study business practices, and also organize visits to CNPC-affiliated oilfields in China for business exchanges.

CNPC AktobeMunaiGas supports the education of Kazakhs by setting up education funds, sponsoring academic meetings of higher education institutions, holding nationwide debates for college students, and sponsoring Kazakh students to study overseas. In 2000, the company allocated USD 1 million in education funds to support young Kazakh experts, outstanding students, and talented students from poor families. In 2008, we contributed USD 776,900 to support education in Kazakhstan. This included financing the study of 77 young Kazakhs at the China University of Petroleum (Beijing) and 35 students in Kazakhstan.

PK has also set up a special education fund to finance the education of excellent young Kazakhs. It has helped many middle school students from rural and mountainous areas to receive higher education at home and abroad. With the support of the Kyzylorda government, in 2005, PK established a scholarship to finance the college education of local outstanding students, and provide full scholarships to facilitate the sharpening of skills and talents that fally significantly short of the demands of the Kazakh oil industry. After acquisition, PK has provided higher education opportunities to 54 Kazakh middle school students.

In 2010, the CNPC's Kazakhstan project companies spent RMB 5 million in total to help outstanding local youth receive education in prestigious universities in China, Kazakhstan and other countries.

In 2011, the Kazakhstan branch of CNPC affiliated China Petroleum Engineering and Construction Corp. worked with the local universities to broaden the channel of executive search. Meanwhile, long-term training cooperation programs between the company and local universities and colleges such as Aktobe Institute of Technology and No.2 Shymkent Vocational School are under way to offer theoretical training to local employees. The training bases in Shymkent and Zhanazhol can provide simultaneous training to 25 welders, 30 pipeline workers and 30 riveters.

In 2012, the Company provided the Education Ministry of Kazakhstan with supporting 15 Kazakh students to take master’s degree programs in China. We also invested RMB 25 million to support infrastructure, education and medical development in Aktobe.

Localization and Diversification

CNPC AktobeMunaiGas employs 20,000 local people from more than 10 nationalities, accounting for nearly 15% of the city's workforce and more than 97% of employees in major oil and gas investment businesses. This makes it the firm with the highest percentage of local staff among all the foreign businesses operating in Kazakhstan.

We respect different customs and religious freedom, and follow Kazakh customs in food, marriages, funerals and festivals. During important national festivals and holidays, we organize grand get-togethers to celebrate with the local employees. Meanwhile, we have created various platforms to remove linguistic and cultural barriers between employees from China, Kazakhstan, Russia and the West.

In 2005, CNPC took over the operation and management of PetroKazakhstan Inc. More than 4,000 employees from more than 10 countries like Kazakhstan, US, Canada and China were grappling with their many differences in terms of language, culture, religion, customs, lifestyles and values. We have built a culture of mutual trust based on effective communication in PK. We also organize language training and encourage collective activities to facilitate employee communication. The training also provides insights into Chinese, Kazakh and Western traditional cultures, and this has greatly enhanced mutual understanding. We also organize outings on holidays, and hold banquets and parties to boost cultural exchang4es within the company.

BGP, a CNPC subsidiary, shows respect for local cultural and religious customs and has won the trust of the local employees. In 2011, the percentage of employees working with the company for three years or more is above 60% and even up to 80% in some regions. A questionnaire shows that it is the personal goal of 96% of foreign employees to become a “Star Employee” of BGP.

Community building

Since 1997, CNPC AktobeMunaiGas has signed a socio-economic cooperation memorandums with the province of Aktobe to help beef up the rural infrastructure, develop agriculture, build public facilities and boost education, culture, sports, healthcare, and poverty relief. In 2008, CNPC AktobeMunaiGas honored its USD 6.38 million commitment in the Socio-Economic Cooperation Memorandums. From 2006 to 2008, PK signed Socio-Economic Cooperation Memorandums with the governments of Kzyl-Orda and South Kazakhstan and put USD 15 million in local infrastructure construction, urban heating, agricultural development, sports, culture, education, healthcare, and other public welfare projects.

In the past decade, CNPC has taken several initiatives to help disadvantaged groups. In May 2003, CNPC AktobeMunaiGas Built 80 homes for widowed seniors and veterans of World War II. The company also set aside USD 63,700 to subscribe to newspapers and magazines, and sponsors a Veteran Soldier Festival every year. To improve healthcare service, CNPC AktobeMunaiGas had donated a57 ambulances to Aktobe province by 2008. We also spent RMB 23.73 million on the construction and maintenance of infrastructure, hospitals, and cultural and religious venues in Aktobe and Astana in 2010.

CNPC also carries out public welfare projects in cooperation with non-governmental organizations. PK has been supporting the Foundation for Promoting Employment of the Socially Insecure Kazakh Citizens and Social Security. From 2006 to 2007, the company allocated USD 56.3 thousand to carry out projects aimed at socially vulnerable groups. In 2008, PK supported the foundation in its efforts to promote temporary and long-term employment, develop the urban infrastructure, and assess the condition of people not covered by social security.

Support for Culture and Sport

Since 1997, CNPC AktobeMunaiGas has sponsored many social and cultural activities in Aktobe. For example, the company has sponsored the Aktobe soccer club, financed the local museum and monument, and backed academic meetings, art exhibitions and concerts. In 2006, the company invested USD 793,100 in building the monument and museum in honor of the Kazakh musician Zhubanov, and held a nationwide commemoration for him. CNPC AktobeMunaiGas also provides strong support to the development of both popular and professional sports, including weightlifting, swimming, hockey and free boxing. In recent years, the Aktau soccer club, which is sponsored by CNPC AktobeMunaiGas, has recorded a string of successes.

Since 2000, PK has been supporting a fund for young people, whose aim is to introduce economics to middle and primary school students and hone their social skills. It has benefited 37,000 middle and primary school students. Meanwhile, PK also joined hands with the provincial government of Kyzylorda to set up a Development Fund, for promoting local culture and sports. A local soccer team named Caesar, set up under this fund's support, even won a national championship. This money also helped renovate the central stadium of Kazakhstan and given the sport of weightlifting a leg up.
