This equates to about 34 days of oil at 2013 daily U.S. consumption levels of 18.49 million barrels per day (2,940,000 m3/d)[3] or 64 days of oil at 2013 daily U.S. import levels of 9.859 million barrels per day (1,567,500 m3/d).[4] However, the maximum total withdrawal capability from the SPR is only 4.4 million barrels per day (700,000 m3/d), so it would take over 144 days to use the entire inventory. At recent market prices ($-37 a barrel as of April 2020),[5] the SPR holds over $-9.26 billion in sweet crude and approximately $-20.4 billion in sour crude (assuming a $15/barrel discount for sulfur content). In 2012, the total value of the crude in the SPR was approximately $43.5 billion, while the price paid for the oil was $20.1 billion (an average of $28.42 per barrel).[6]
