  "account": "Six months into the U.S.-Israeli war with Iran, Washington faces an uncertain future for the Strategic Petroleum Reserve (SPR), according to a Reuters analysis. Established after 1970s oil crises, the SPR holds crude in underground salt caverns along Texas and Louisiana coasts. After years of releases by former President Joe Biden and President Donald Trump, the reserve is now at its lowest level since 1982, containing just 289.7 million barrels. The level could drop to about 243 million if President Trump releases a final batch of 39 million barrels, as agreed in a March deal with the International Energy Agency. More than 30 countries agreed to release a record 400 million barrels, with the U.S. contributing 172 million, to calm markets after the U.S.-Israel war began on February 28.\n\nThe minimum operating level for the SPR is 70 million barrels, but a Department of Energy source suggests the practical minimum is closer to 250 million barrels. Operating below this threshold puts the infrastructure at risk, as it forces the caverns to float water, which can damage cavern walls and pipes. While President Trump announced plans to refill the SPR using Venezuelan oil, the timeline for this replenishment remains unclear. The U.S. has also agreed to a deal with Caracas to revive Venezuela's oil industry, which could result in control of a fifth of its crude reserves. However, the replenishment process could take years and may be cut short by domestic and Venezuelan elections.\n\nThe depletion of the SPR has been a gradual process, driven by the U.S. oil boom since 2008, which made the country a net petroleum exporter. In 2021, President Biden released about 230 million barrels of SPR oil to help lower oil prices amid Russia's invasion of Ukraine. While the reserve has been replenished since then, the interruption caused by the Iran war has halted further fill-ups. Additionally, limited funding for replenishment has been a significant challenge. Congress provided only $171 million last year, far below the $20 billion needed at the time.\n\nDespite the SPR's generally good condition, the Department of Energy (DOE) is concerned about the integrity of the wells due to ongoing maintenance needs and major construction intended to address these issues. The GAO reported in May that the SPR's drawdown, distribution, and fill capabilities are currently limited and at risk due to aging infrastructure and ongoing construction. As a result, oil market watchers are worried about the SPR's precarious state and the potential for oil prices to spike if the reserve is drained further.",
