Political and economic unrest in the Arab world have sent gas prices skyrocketing in the United States in recent weeks, and some lawmakers are ready to tap into the country's Strategic Petroleum Reserve. What is that, and how much oil is in it?
The reserve was formed following an energy crisis of a different era. In October 1973, the Organization of Arab and Petroleum Exporting Countries (OAPEC) shut off oil supplies in response to United States support of the Israeli military during the Yom Kippur War. The oil embargo, which lasted until the following March, caused a global energy and economic crisis. To prevent such a situation from arising again, the U.S. government created the Strategic Petroleum Reserve (SPR) in 1975. Several other countries also created oil reserves, but the American stockpile was and remains the biggest.
As of March 7, the SPR consists of 726.5 million barrels of crude oil stored in underground caverns at four secure locations along the Gulf Coast, a spokesperson at the U.S. Department of Energy told Life's Little Mysteries, a sister site to LiveScience. The biggest reserve site is Bryan Mound, near Freeport, Texas. There, 254 million barrels fill 20 manmade caverns that have been hollowed out beneath salt domes a few thousand feet underground. The other three reserve sites are Big Hill in Winnie, Texas, West Hackberry in Lake Charles, LA, and Bayou Chocktaw in Baton Rouge, LA.
