The board of Russia's Gazprom approved two Kazakhstan-related arrangements tied to long-term processing of gas from Kazakhstan's Karachaganak field at Russia's Orenburg gas processing plant, Interfax reported May 22. The arrangements include a transaction with QazaqGaz, KazRosGaz and Gazprom Pererabotka, as well as a Dec. 30, 2025, guarantee agreement with Samruk-Kazyna and Gazprom Pererabotka.

Gas from Karachaganak has been processed at Orenburg since 1984, and current annual supplies are about 9 billion cubic meters. The arrangements follow an October 2025 agreement on the main terms for processing Karachaganak gas at Orenburg and the modernization of the plant. Gazprom's public disclosures do not provide the processing tariff, pricing formula or capital expenditure allocation.
