Office of Petroleum Reserves

You are here


The mission of the Office of Petroleum Reserves (OPR) is to protect the United States from severe petroleum supply interruptions through the acquisition, storage, distribution, and management of emergency petroleum stocks, and to carry out the U.S. obligations under the International Energy Program. The OPR manages the operational readiness of  three emergency stockpiles - the Strategic Petroleum Reserve (SPR), the United States’ crude oil stockpile;  the Northeast Home Heating Oil Reserve (NEHHOR), a one million barrel stockpile of ultra-low sulfur distillate (diesel/heating oil); and the Northeast Gasoline Supply Reserve (NGSR), a one million barrel supply of gasoline. In the event of a natural disaster or other national emergency, the United States can rely on these emergency stockpiles to maintain a constant supply of crude oil and other petroleum products.



OPR directly supports the Department of Energy's primary goal of energy dominance by ensuring energy security for America.
