Who We Are

Chevron Caspian Exploration B.V., headquartered in Rotterdam, is a premier international energy company and a vital arm of a global energy leader.

Our history is closely interlinked with the rise of an independent Kazakhstan. Since taking over operations at Tengiz in 1993, we have grown into a leading producer of oil, gas, and associated products that fuel the modern economy. Tengizchevroil (TCO), our flagship joint venture, stands as a testament to international partnership and engineering excellence.

We safely and reliably produce the products that heat homes, fuel cars, support businesses, and benefit society — creating lasting value for our shareholders, host communities, and our people.
