Introduction to Chevron Corporation
Chevron Corporation is one of the world’s leading integrated energy companies, with operations spanning exploration, production, refining, and marketing of petroleum products. Headquartered in San Ramon, California, Chevron operates across more than 180 countries and manages a wide network of oil and gas assets. Its refining operations are critical to the company’s value chain, enabling the transformation of crude oil into usable products such as gasoline, diesel, jet fuel, lubricants, and petrochemicals.
The company’s refining segment is structured under its "Downstream" operations, which also include marketing, lubricants, and trading. Chevron’s refineries are strategically located to serve markets in North America, Asia-Pacific, and Africa.
The Role of Refineries in Energy Supply
Refineries are complex industrial facilities where crude oil undergoes processing through distillation, cracking, reforming, and treatment. These processes separate crude oil into components based on boiling points, and then transform heavy fractions into lighter, more valuable products.
Key products from Chevron refineries include:
- Gasoline: Fuel for automobiles, one of the highest-demand products globally.
- Diesel: Used in trucks, shipping, and industrial equipment.
- Jet Fuel: Critical for aviation.
- Liquefied Petroleum Gas (LPG): Used in cooking, heating, and petrochemical feedstock.
- Lubricants: Essential for machinery, vehicles, and industrial operations.
- Asphalt and Residual Fuels: Used in construction and power generation.
Without refining, crude oil would have little practical value. Chevron’s refineries therefore serve as a backbone of modern energy infrastructure.

Pascagoula produces a wide range of products and exports significant volumes internationally due to its access to deepwater shipping.
3. El Segundo Refinery (California, USA)
Situated near Los Angeles International Airport, this refinery has a capacity of about 269,000 barrels per day. It plays a critical role in supplying Southern California with fuels and aviation products.
4. Kapolei Refinery (Hawaii, USA) – Closed in 2020
Chevron previously operated a refinery in Hawaii, but in 2020 the company exited refining in the state due to market challenges.
5. Burnaby Refinery (British Columbia, Canada)
This refinery supplies fuels to western Canada and has a smaller capacity compared to Chevron’s U.S. operations.
6. Refinery Interests in Asia-Pacific and Africa
Chevron owns and operates refineries or joint ventures in Singapore, Thailand, South Africa, and other regions, enabling the company to serve fast-growing energy markets in Asia and beyond.
Refining Capacity and Global Presence
Chevron’s total refining capacity exceeds 1.8 million barrels per day, placing it among the top global refiners. However, Chevron has historically focused more on upstream production and integrated operations rather than competing purely as a refining giant like ExxonMobil or Shell.
Refineries are strategically located near crude oil supply hubs, shipping lanes, and major consumer markets. This ensures Chevron can supply fuels efficiently and remain competitive in regional and global markets.
Environmental and Community Impact
Refineries, while essential, often raise environmental concerns. Chevron refineries have been at the center of debates around air quality, water use, and community health.
Key environmental issues include:
- Air Emissions: Refineries emit pollutants such as sulfur dioxide, nitrogen oxides, volatile organic compounds, and particulates. Chevron has invested in emission control technologies to meet regulatory standards.
- Greenhouse Gas Emissions: Refining is carbon-intensive. Chevron has pledged to reduce its carbon footprint and invest in carbon capture technologies.
- Water Pollution: Wastewater management and accidental leaks are concerns, especially in coastal refineries.
- Community Health and Safety: Accidents, such as the 2012 fire at the Richmond Refinery, have highlighted safety risks. Chevron has since made safety upgrades and strengthened engagement with local communities.
Chevron has also invested in environmental restoration projects and renewable energy initiatives near its refineries. For example, the Richmond Refinery has solar panels on-site and funds community programs for education and workforce development.
Refinery Accidents and Safety Measures
Due to the complex and hazardous nature of refining, accidents can occur despite safety measures. Chevron has faced several high-profile incidents, including:
- 2012 Richmond Refinery Fire: A pipe leak caused a fire that released smoke over residential areas. Thousands of residents sought medical attention. The incident led to lawsuits, fines, and increased scrutiny of refinery safety.
