Strategic Petroleum Reserve Was Officially Established in Late 1975

It was the mid 1970s, and the United States had a big problem.

During the Yom Kippur War, members of the Organization of Arab Petroleum Exporting Countries imposed an oil embargo against the United States. The embargo was in retaliation for America's support of Israel in the conflict.

The embargo had disastrous consequences, causing a quadrupling in oil prices. The United States realized how vulnerable they were to an oil shock, and they made moves to lessen the future impact via the Energy Policy and Conservation Act (EPCA), which was signed into law in late 1975 by Gerald Ford.

This Act established the Strategic Petroleum Reserve (SPR). By purchasing hundreds of millions of barrels of oil and stashing them around the country, the United States would be able to better protect itself against future spikes on oil.

As of this moment, the US Strategic Petroleum Reserve sits at 411 million barrels. This is far below its capacity of 714 million barrels. President Trump has vowed to replenish the Strategic Petroleum Reserve, and the refilling is currently under way.

The oil in the Strategic Petroleum Reserve is kept in four locations - Bryan Mound (Brazoria County, Texas), Big Hill (Jefferson County, Texas), West Hackberry (Cameron Parish, Louisiana) and Bayou Choctaw (Iberville Parish, Louisiana).

The oil is stored in heavily guarded, underground salt caverns along the coast of the Gulf of Mexico. The caverns are connected to commercial pipelines and refineries, which is why the oil is stored in those particular locations.

Peak inventory levels for the US SPR was hit in December of 2009. At that point, the US was actually over capacity, and had 726.6 million barrels of oil in its reserves.

Oil was released at strategic times over the years in order to try and manage prices. Oil, for instance, was released from the SPR before the Gulf War in 1990 and after Hurricane Katrina.

There was a massive 180 million barrel drawdown in 2022, due to the war between Russia and Ukraine, as the United States tried to stabilize oil prices throughout the world.

In 2023, the supplies in the Strategic Petroleum Reserve hit a 40-year low, as there was just 351.8 million barrels in the reserve, which was less than half of capacity.

In February of 2025, the Trump Administration launched an initiative to refill the SPR. The strategy is to buy oil when it is less than $80/barrel - this initiative is expected to be completed by 2028.
