Chevron 

Chevron Corporation functions as a global energy and chemicals powerhouse, orchestrating its diverse operations worldwide. The company's business is organized into two primary divisions: Upstream and Downstream. The Upstream segment focuses on the full lifecycle of crude oil and natural gas, from their initial exploration and development to production and subsequent transportation. This also encompasses the processing, liquefaction, transit, and regasification of liquefied natural gas (LNG), as well as pipeline transport of crude oil and the movement, storage, and sale of natural gas. Additionally, this segment manages a facility dedicated to converting natural gas into liquid fuels. In contrast, the Downstream segment is tasked with refining crude oil into a variety of petroleum products. Its activities include the merchandising of crude oil, refined goods, and lubricants, in addition to the creation and distribution of renewable fuels. This division is also responsible for moving crude oil and refined products using a range of methods, including pipelines, ships, motor vehicles, and rail cars. Furthermore, it produces and markets bulk petrochemicals, industrial-grade plastics, and additives for both fuels and lubricants. Beyond these core ventures, Chevron is also involved in financial management, debt financing, insurance underwriting, real estate development, and various technology-driven enterprises. Founded in 1879, the company operated as ChevronTexaco Corporation until it officially became Chevron Corporation in 2005. Its corporate headquarters are situated in San Ramon, California.
