Fact Sheet
Year-end 2015

History and Ownership
• Tengiz, the world’s deepest producing super giant oil field, was discovered in 1979.
• The Tengizchevroil (TCO) partnership was formed on April 6, 1993, between the Republic of Kazakhstan and Chevron. Current partners are Chevron, 50 percent; KazMunaiGas, 20 percent; ExxonMobil Kazakhstan Ventures Inc., 25 percent; LukArco B.V., 5 percent.

Production and Reserves
• Total recoverable crude oil in the Tengiz and Korolev fields is estimated to be 750 million to 1.1 billion metric tonnes (6 to 9 billion barrels). Estimated oil in place in the Tengiz field is 3 billion metric tonnes (25 billion barrels) with 190 million metric tonnes (1.5 billion barrels) in the Korolev field. The areal extent of the Tengiz reservoir is large, measuring 20 kilometers (12 miles) by 21 kilometers (13 miles).
• TCO completed its Sour Gas Injection and Second Generation Plant expansion project in 2008, which brought daily production capacity to approximately 75,000 metric tonnes (600,000 barrels) of crude oil and 22 million cubic meters (750 mscf) of natural gas.

Crude Production
• Crude production for 2015 was 27.16 million metric tonnes (217 million barrels). This is a new annual production record.

Product Sales
• In 2015 TCO sold over 1.27 million metric tonnes of LPG and 6.85 billion cubic meters of dry gas.
• TCO sold over 2.7 million tonnes of sulfur, which is 113 percent of the 2.4 million tonnes produced for the same period.
• TCO’s premium sulfur is sold in three different forms to customers in many countries, including Kazakhstan, Russia, Ukraine, China and other countries primarily in the regions of the Mediterranean Sea and Atlantic Ocean.

Health, Safety and the Environment
• TCO has invested $3 billion since the year 2000 on projects to minimize environmental impact.
• Such investments in environmental protection have enabled TCO to reduce total gas flaring volumes by 85 percent since the year 2000. TCO’s current gas utilization rate is over 98 percent.
• Total air emissions generated per tonne of oil produced have been reduced by 73 percent since 2000. For 2015, TCO averaged 2.24 kilograms of emissions per tonne of oil produced. Since 2000, TCO has increased annual crude oil production volume by 159 percent.
• Investments in environmental protection and improvements in plant reliability have helped TCO to achieve reduction in the number of technical malfunctions at the KTL plant by 40 percent in 2015, and the volume of sour and acid gas flaring during technical malfunctions by 93 percent from 2000 to 2015.
