This is a two part answer. The second part you will not like at all.
The U.S. draws down its reserves and exports oil simultaneously due to type mismatches, global crises, and refinery economics. [1, 2, 3]
The primary reasons for this dynamic include:
- Oil Grade Mismatch: Most U.S. shale extraction yields “light, sweet” crude, while many domestic refineries are built to process heavier, “sour” crudes. The U.S. exports the light crude it produces in excess and imports the heavier crude needed by its coastal refineries.
- Global Supply Shocks: International conflicts—such as the Middle East conflict and Strait of Hormuz disruptions—have tightened global supplies. The U.S. has tapped into its Strategic Petroleum Reserve (SPR) to stabilize global markets, temper price surges, and support allies, bringing SPR levels to their lowest since 1983.
- Market Profitability: Oil companies are private entities. Because global demand for U.S. crude is high (especially from countries whose refineries are perfectly configured for it), companies export it for profit rather than routing it domestically. [1, 8, 9]
If you want, let me know:
- Would you like to see a breakdown of how much oil the U.S. currently imports vs. exports?
- Are you interested in the specific impact of these SPR releases on current gas prices?

Major US oil and refining companies do own a significant amount of refining capacity internationally, making up millions of barrels per day of global production. However, it is actually foreign-owned entities (e.g., Saudi Aramco, BP, and TotalEnergies) that own a larger share of US domestic refining capacity. [1, 2]
US oil majors primarily split their assets between domestic facilities and global markets in a few key ways:
Global Assets of US Companies
American integrated oil companies (like ExxonMobil and Chevron) own and operate significant refining capacity outside the US to serve international demand and process local crude sludges closer to where they are drilled.
- ExxonMobil: Operates large global facilities such as the Jurong Island Refinery in Singapore and the Antwerp Refinery in Belgium.
- Chevron: Holds major refining assets and joint ventures internationally, particularly in the Asia-Pacific region.
- Marathon Petroleum: Historically a heavily domestic refiner, they also participate in international supply chains, though their primary physical assets remain within the United States. [3, 4, 5]
Foreign Ownership of US Refineries
Conversely, foreign state-owned and private oil corporations own approximately 28% of US domestic refining capacity, controlling roughly 5 million barrels per day of the fuel produced on American soil.
- Saudi Aramco: Owns Motiva Enterprises, which operates the largest refinery in the United States (Port Arthur, Texas), allowing them to process their crude in the US.
- BP & TotalEnergies: British and French multinational energy companies own major US facilities, such as BP’s Whiting Refinery in Indiana.
- Petróleos de Venezuela (PDVSA): Historically owned massive US refining assets (like Citgo) as strategic outlets for heavy Venezuelan crude, though this ownership has shifted over the years. [6, 8, 9, 10, 11]
Why the Market is Split
Global refining is highly specialized. Many US refineries were historically upgraded to process heavy, sour crude oils from the Middle East and Latin America. Therefore, US companies export lighter, domestically drilled crude while US refineries import heavier crudes, creating a complex global web of cross-ownership and trade. [12, 13, 14, 15, 16]
