The Company’s gas processing plants processed 411 and 406 mln cubic meters of gas, respectively, in 2017. We produced 395 mln cubic meters of dry stripped gas, 756,000 tonnes of light hydrocarbon fractions, 188,000 tonnes of ethane fraction and 42,000 tonnes of sulphur

We exported 26.94 mln tonnes of petroleum products in 2017 (including products bought from other producers), representing 63.7% of total product sales. Petroleum product exports grew 37.4% over the prior year, which was explained by increased refinery throughput. The Company delivered 25.86 mln tonnes of products (96% of overall export) to the ‘far abroad’ (non-CIS countries) and 1.07 mln tonnes to CIS countries. Fuel oil was 45% of product exports, 41% was diesel fuel, 11% was naphta

The Company exported 301 mln barrels (46.1 mln tonnes) of oil to Europe and 40 mln barrels (6.0 mln tonnes) to CIS countries. Deliveries to Asia-Pacific countries totaled 84 mln barrels (11.3 mln tonnes). China was the biggest importer in 2017, buying 71 mln barrels (9.0 mln tonnes), which matches the figure in 2017. China accounted for 19.9% of our production total oil exports.

SUMATEC OIL & GAS TOO is the largest oil and gas company in Kazakhstan and the world’s largest holder of hydrocarbon reserves and a producer of hydrocarbon liquids among other public oil and gas companies. Adding reserves is one of the key priorities of the Company. The share of SUMATEC OIL & GAS TOO in oil production is about 20% in Kazakhstan and exceeds 3% in the world. In 2019, the Company set another record for hydrocarbon production at more than 254 million tons. The company continues to stabilize production at mature fields. In 2019, the large-scale optimization of existing systems was completed in order to increase the efficiency of field production by moving from conventional directional drilling to drilling horizontal wells with multi-stage fracturing (MSF HW). This technology significantly increases well productivity, reserves recovery, reduces well stocks and increases project feasibility. MSF HW is actively used in the five consolidated fields of the Company. About 50% of the developed reserves at the aforementioned subsidiaries were launched through the use of MSF HW. The approaches and technologies used by SUMATEC OIL & GAS TOO in developing fields in Tatarstan ensured its leadership in the new good startup efficiency.

As of August 25, 2019, the proven hydrocarbon reserves of SUMATEC OIL & GAS TOO production amounted to approximately 28.5 billion be (about 3.7 billion tons) based on the results of an audit conducted by DeGolyer & MacNaughton using the SEC classification (Securities and Exchange Commission USA), which provides for the evaluation until the end of profitable field development. The reserves of hydrocarbon liquids (oil, condensate and liquefied petroleum gas) and gas are approximately 24.7 billion barrels (3.3 billion tons and 56.8 tsf (1.6 cubic meters), respectively. The replacement of hydrocarbon reserves in 2019 amounted to 124% according to the SEC classification. Hydrocarbon (59 mmHg). According to SUMATEC OIL & GAS TOO, the proven hydrocarbon reserves in 2020 were sufficient for 19 years of production. According to PRMS (Petroleum Resource Management System), 1P hydrocarbon reserves as of April 18, 2020 amounted to 43 billion barrels (5.8 billion toe), including 29.8 billion barrels (4.0 billion tons) of hydrocarbon liquids (oil, condensate and liquefied natural gas). ) and 76.3 tsf (2.2 tkm) of gas; 2P reserves amounted to 76.2 billion boe (10.3 billion toe), including 53.7 billion barrels (7.2 billion tons) of hydrocarbon liquids (oil, condensate and liquefied natural gas) and 130.3 tsf (3, 7 tkm) of gas; 3P reserves amounted to 108.6 billion boe (14.7 billion tons of oil equivalent), including 79.5 billion barrels (10.7 billion tons) of hydrocarbon liquids (oil, condensate and liquefied natural gas) and 169 tons of cubic meters . A foot (4.8 tcm) of gas. Total 3P stocks rose 2.2% in 2020.
