In 2025, KazTransOil JSC ensured the stable and uninterrupted operation of its trunk oil pipeline system by implementing a comprehensive set of measures aimed at diversifying export routes and expanding international cooperation.

Amid ongoing volatility in global energy markets, the Company-working closely with shippers and international partners-carried out extensive coordination and negotiations. As a result, part of export volumes was redirected from the CPC pipeline system to alternative routes, including the seaports of Novorossiysk and Ust-Luga, the Adamova Zastava crude oil delivery point, and the Atasu-Alashankou oil pipeline. Transit to the Republic of Uzbekistan and supplies to the Kyrgyz Republic were resumed, while KazTransOil strengthened its presence in Europe by opening a representative office in Poland.

In 2025, crude oil transportation via KazTransOil’s trunk pipeline system alone amounted to 45.120 million tonnes, exceeding the 2024 level by 1% and marking the highest result in the past seven years.

Crude oil throughput across the trunk pipeline system reached 36.002 billion tonne-kilometers, up 1% year-on-year. KazTransOil’s consolidated crude oil throughput totaled 46.057 billion tonne-kilometers, representing a 2% increase compared to 2024.

Supplies of crude oil to Kazakhstan’s domestic refineries in 2025 amounted to 18.045 million tonnes, up 4% from the previous year, including:

Atyrau Oil Refinery LLP – 5.345 million tonnes

PetroKazakhstan Oil Products LLP – 6.226 million tonnes

Pavlodar Petrochemical Plant LLP – 5.778 million tonnes

CASPI BITUM Joint Venture LLP – 0.696 million tonnes.

Crude oil transportation along the Atyrau-Samara section of the Uzen-Atyrau-Samara trunk pipeline totaled 11.134 million tonnes, up 7% year-on-year. Within this volume, deliveries of Kazakh crude to the Transneft pipeline system for onward supply to Germany increased by 44%, reaching 2.146 million tonnes.

Transportation via the TON-2 pipeline section located in Kazakhstan amounted to 11.867 million tonnes, remaining at the 2024 level.

A total of 11.086 million tonnes of crude oil was transferred into the Atasu-Alashankou trunk pipeline, down 1% compared to 2024.

Oil transfers into the Caspian Pipeline Consortium – Kazakhstan (CPC-K) JSC system amounted to 3.559 million tonnes, a 15% decrease year-on-year.

Crude oil loading onto tankers at the Port of Aktau, using KazTransOil facilities, totaled 3.226 million tonnes, down 4% from 2024. Shipments along the Baku-Tbilisi-Ceyhan (BTC) route declined by 11% to 1.263 million tonnes.

Through the Kazakhstan-China Pipeline LLP system, 19.500 million tonnes of crude oil were transported, representing a 4% increase year-on-year. Throughput reached 17.471 billion tonne-kilometers, also up 4%.

Transportation via the MunaiTas North-West Pipeline Company LLP amounted to 6.129 million tonnes, a 6% increase compared to 2024. Throughput rose by 8% to 2.586 billion tonne-kilometers.

Across the Batumi Oil Terminal LLC Group and Petrotrans Limited, the volume of transshipped petroleum products and gas during the reporting period reached 1.913 million tonnes, up 3% year-on-year. Total cargo transshipment in 2025 amounted to 7.284 million tonnes, exceeding the 2024 level by 10%.

Supplies of fresh water to consumers in Kazakhstan’s Atyrau and Mangystau regions via the Astrakhan-Mangyshlak water pipeline totaled 25.911 million cubic meters, which is 2% lower than in 2024.

In 2026, KazTransOil JSC will continue efforts to fulfill state-mandated objectives related to ensuring national energy security and meeting Kazakhstan’s export commitments
