As of January 2023, the U.S. Strategic Petroleum Reserve (SPR) held approximately 371.6 million barrels of crude oil. Based on the current rate of withdrawals from the SPR, which has averaged around 1.3 million barrels per day over the past year, the U.S. oil reserves are projected to last for approximately 286 days, or about 9.5 months. However, it's important to note that the U.S. government can adjust the rate of withdrawals from the SPR, so the actual timeline may vary depending on future decisions. Additionally, the SPR is periodically replenished, so the amount of oil in reserve can fluctuate over time.
