After falling to the lowest level in 4 decades...what worries Americans about the strategic oil reserve?

Experts warned this week that the caves where the US stores its strategic petroleum reserves could be damaged by the rapid drawdown of stockpiles in response to the war with Iran, with reserves reaching their lowest level in four decades. Experts said that damage to the caves would make it difficult for the United States to respond to future energy emergencies. The oil is stored in the US Strategic Petroleum Reserve (SPR).

Inside 60 salt caves thousands of feet underground, distributed over four main locations on the Gulf Coast of Louisiana and Texas. Reserve stocks fell below 300 million barrels for the first time since they were filled in the early 1980s, according to Energy Department data released Monday. Stocks are declining as the United States withdraws 172 million barrels in response to supply disruptions caused by the war with Iran.

The reserve is expected to stabilize at about 243 million barrels after the withdrawal operations are completed. The Energy Department said at least 70 million barrels must remain in reserve in order to safely manage the caverns. But Amos Hochstein, a former senior energy adviser to President Joe Biden, cast doubt on that number this week. “Don't believe former government officials who say the Strategic Petroleum Reserve can...

It decreases to 70 million barrels. This is nonsense." He added that reaching this level would deplete the reserve "to the point where it would be impossible to revive it again." Hochstein had warned in June that falling reserves below 300 million barrels would expose the caves to the risk of damage. "I don't know anyone who believes we can go below 300 million barrels," he said at an Atlantic Council event. I know a lot of people think we can't even get close to 300

Million, because that would actually cause damage to the caves in which the oil is stored." For its part, the Department of Energy said that claims about the risk of salt storage caverns collapsing as oil levels fall are untrue. Department spokesman Ben Dietrich said in a statement to CNBC: "The caverns are always full. All that changes is the ratio of oil to the water that fills it.” He added that President Donald Trump’s administration “manages the Strategic Petroleum Reserve

"Responsibly as a critical national security asset, which is what it was designed for." Members of both Republicans and Democrats have expressed concerns about the safety of the salt caverns. Republican lawmakers had raised those concerns when the Biden administration released a record 180 million barrels of reserves in 2022, in response to Russia's invasion of Ukraine. The reserve fell to less than 350 million barrels in 2023 during the Biden administration, before returning

Filling it to about 415 million barrels before the war with Iran. The US Government Accountability Office (GAO) said in a report issued in May that repeated partial withdrawals followed by refilling operations may repeatedly dissolve a certain portion of the cave, resulting in undesirable cave shapes. The office found that the majority of the reserve caves were in “very good condition” after the 2022 withdrawal. But it noted that each withdrawal cycle leads to an increase in the size of

Caving and reducing the distances between caves inside the salt dome, which ultimately reduces their ability to continue in the long term. Operational reserve limit To extract oil from the reserve, operators pump water to the bottom of caverns to push crude oil to the surface, then pump it through wells to pipelines. Siddharth Misra, professor of petroleum engineering at Texas A&M University, said 70 million barrels represents the physical minimum.

The rigidity required to keep the extraction tubes safely immersed in oil rather than water. But Misra said, “The practical operational limit for crude oil inventory is between 250 million and 300 million barrels.” He added that current stock levels mean that "cave safety and overall operational capacity face elevated risks." He explained that the decrease in inventory
