The Strategic Petroleum Reserve (SPR) is an emergency stockpile of petroleum maintained by the United States Department of Energy (DOE). It is the largest publicly known emergency supply in the world; its underground tanks in Louisiana and Texas have capacity for 714 million barrels (113,500,000 m3). The United States started the petroleum reserve in 1975 to mitigate future supply disruptions as part of the international Agreement on an International Energy Program, after oil supplies were interrupted during the 1973–1974 oil embargo.
An oil refinery or petroleum refinery is an industrial process plant where petroleum is transformed and refined into useful products such as gasoline (petrol), diesel fuel, asphalt base, fuel oils, heating oil, kerosene, liquefied petroleum gas and petroleum naphtha. Petrochemicals feedstock like ethylene and propylene can also be produced directly by cracking crude oil without the need of using refined products of crude oil such as naphtha. The crude oil feedstock has typically been processed by an oil production plant. There is usually an oil depot at or near an oil refinery for the storage of incoming crude oil feedstock as well as bulk liquid products. In 2020, the total capacity of global refineries for crude oil was about 101.2 million barrels per day.
