The Strategic Petroleum Reserve, 1977–2026

In this chart: Strategic Petroleum Reserve

About this chart

The glass sphere is the Strategic Petroleum Reserve, and the liquid in it is how much it holds: the share of the sphere's circle that is filled is the share of the record high held, so half full sits at the middle and the surface moves fastest near empty and near full. Scale marks stand beside the glass at a quarter, a half and three quarters. The readout carries the date, the crude oil held in millions of barrels and the share. The animation runs the record over fifty-six seconds, holds on the last date for three seconds, and loops. The scrubber under the chart marks every year and labels the decades (every fifth year on a short record), and pauses on any date; the speed can be changed in the controls.

Method

The amount is the crude oil held in the US Strategic Petroleum Reserve, the federal government's emergency stock in salt caverns on the Gulf Coast, as the U.S. Energy Information Administration reports it: its monthly figure for the end of each month from October 1977, when the first barrels arrived, to July 1982, and its weekly figure for every week from 20 August 1982, when the weekly series begins, to the latest week it reports. The two series are the same quantity, the reserve's ending stocks, and meet without a step. There is no stated capacity to fill against: the Department of Energy gives an authorized storage capacity of 714 million barrels, but the reserve held more than that from 2009 to 2011, so the sphere is full at the most it has ever held, 726.6 million barrels in the week of 1 January 2010, and the share is of that high. The sphere fills by the area of its circle, so half full sits at the middle. Every figure on the page is computed from the rows the page serves.

Data table

The crude oil held in the US Strategic Petroleum Reserve, in thousands of barrels: the Energy Information Administration's monthly ending stocks for October 1977 to July 1982, then its weekly ending stocks from 20 August 1982 to the latest week. The share is each figure over the record high, 726,617 thousand barrels in the week of 1 January 2010. These are the rows the chart draws. Public domain, U.S. Energy Information Administration.
