MOSCOW (Reuters) -A Ukrainian drone attack on Russia’s Orenburg gas plant has forced neighbouring Kazakhstan to reduce production at its Karachaganak oil and gas condensate field by 25% to 30%, two industry sources told Reuters on Monday.
One of the world’s largest gas processing plants, Orenburg was forced to suspend its intake of gas from Kazakhstan after the attack, Kazakhstan’s energy ministry said on Sunday.
Ukraine confirmed it hit a gas plant in the Orenburg region, some 1,700 kilometres (1,060 miles) east of the Russian border with Ukraine, and an oil refinery in the Samara region.
Kyiv has stepped up its attacks on Russian refineries and other energy facilities since August to try to disrupt fuel supplies and deprive Moscow of funding.
Output at Karachaganak on Monday was down to between 25,000 metric tons (196,500 barrels per day) and 28,000 metric tons from the usual level of 35,000-35,500, according to two sources who spoke on condition of anonymity due to the sensitivity of the situation.
They said Orenburg, which is controlled by gas producer Gazprom, might resume some gas intake from Karachaganak on Monday. However, they declined to say when normal levels of supply would be restored.
Oil and gas output at Karachaganak are closely linked, meaning the field is not able to produce much oil if its gas production is down.
Apart from processing at Orenburg, Karachaganak gas is used for re-injection to maintain reservoir pressure as well as for power generation at local facilities.
Karachaganak produced around 263,000 bpd of oil in 2024. It is exported by the Caspian Pipeline Consortium via a Russian Black Sea terminal, as well as through Russia’s Druzhba pipeline to Germany.
The field is operated by a consortium which includes U.S. major Chevron (18%) and European energy firms Shell (29.25%) and Eni (29.25%).
Russia’s Lukoil (13.5%) and local firm KazMunayGaz (10%) also hold stakes.
The consortium, Gazprom, and Kazakhstan’s energy ministry did not reply to requests for comment.
Kazakh authorities agreed with Karachaganak shareholders in 2024 to build a new gas processing plant at the field with annual capacity of up to 4 billion cubic metres, expected to start operations in 2028.
However, the project has been suspended under the current consortium, and the government is seeking new investors, aiming to attract Kazakh companies.
Industry sources has said that oil and gas condensate production at Karachaganak declined in September by 24% from August to 200,000 bpd amid maintenance at the Orenburg plant.
