Kazakhstan Expands Tengiz Oil Field
Kazakhstan has a big oil field called Tengiz, which has been producing oil for over 30 years.
Chevron and other companies have just finished a huge expansion project that cost $48 billion.
This expansion has increased the oil field's production to 1 million barrels a day.
The oil field is very important for Kazakhstan's economy, making up about 10% of its GDP.
Now, Chevron and the Kazakhstan government are starting talks to extend their agreement on the oil field, which is set to expire in 2033.
These talks are important for both sides because the oil field provides a lot of jobs and money for Kazakhstan, and Chevron gets a significant portion of its global production from Tengiz.
The oil field is also facing some challenges, like attacks on the main export route and tensions with OPEC+ over production levels.
