[Sources: Kazakhstan's Oil Production Declines Due to Export Terminal Shutdown Caused by Drone Attack] Golden Finance reports that on July 23, two industry sources stated on Thursday that Kazakhstan's oil production has declined as the country's main crude oil export gateway—the Black Sea terminal—was shut down following a drone attack. The production drop is particularly evident at the Tengiz oil field, the country's largest oil field, led by Chevron. One source revealed that the oil field's output has more than halved, dropping from an average of 925,000 barrels per day in July to approximately 406,000 barrels per day on Wednesday. According to the source, Kazakhstan's total oil and gas condensate production on Wednesday fell from an average of 2.07 million barrels per day in July to 1.63 million barrels per day.
