The United States produces more oil than any other country in the world—averaging 13.3 million barrels per day (MMb/d) in 2024. But strangely, the U.S. also imports about 6.5 MMb/d of crude. This paradox confuses many Americans. Why doesn’t the U.S. just use its own oil? The answer lies in infrastructure mismatches, refinery design, trade economics, and federal laws that restrict the flow of domestic oil.
- 🧪 Light Oil vs. Heavy Oil: Not All Crude Is Created Equal
The U.S. primarily produces light, sweet crude oil, which is low in sulfur and viscosity. Meanwhile, many American refineries—especially those built in the 1970s and 80s—were designed to handle heavy, sour crude, the kind that comes from countries like Venezuela, Mexico, and Canada.
Over 60% of U.S. refinery capacity is optimized for heavy crude processing.
Upgrading a single refinery to handle lighter crude can cost between $100 million to $1 billion.
This means that even though the U.S. produces oil, it’s the wrong kind of oil for its aging refinery infrastructure. So we export light crude (often to Asia and Europe) and import heavy crude to feed our refineries.
- 🏗️ Refinery Location and Infrastructure Gaps
The second major problem is geography. Much of America’s oil production comes from inland fields like the Permian Basin (Texas/New Mexico) or the Bakken Formation (North Dakota). Meanwhile, many of the refineries that need oil are located on the East and West Coasts, far from those production zones.
California, despite being a top 5 oil-producing state, imports ~75% of its crude due to limited pipeline access.
The Keystone XL cancellation and other pipeline delays exacerbate this logistical mismatch.
It’s often cheaper to import oil from the Middle East or Latin America to coastal ports than it is to move domestic crude across the U.S. via expensive trucking, rail, or limited pipelines.
- ⚖️ The Jones Act: A Shipping Law That Backfires
The Jones Act, passed in 1920, requires that any goods (including oil) transported between U.S. ports must use ships that are U.S.-built, -owned, and -crewed. These ships are vastly more expensive to operate than foreign tankers.
A Jones Act tanker costs up to $75,000 per day—nearly 3x more than foreign vessels.
This makes it cheaper to ship oil from Saudi Arabia to New Jersey than from Texas to New Jersey.
The law, originally meant to support the American maritime industry, now creates bottlenecks in the oil supply chain—making domestic crude more expensive to move than imported oil.
