Notes and Definitions
This report tracks U.S. natural gas inventories held in underground storage facilities. The weekly stocks generally are the volumes of working gas as of the report date. Changes in reported stock levels reflect all events affecting working gas in storage, including injections, withdrawals, and reclassifications between base and working gas. Totals may not match sum of components because of independent rounding.
The complete documentation of EIA's estimation methodology is available in the report, Methodology for EIA Weekly Underground Natural Gas Storage Estimates.
Information about the method used to prepare weekly data to compute the 5-year averages, maxima, minima, and year-ago values for the weekly report can be found in Computing the 5-year Averages, Maxima, Minima, and Year-Ago Values for the Weekly Natural Gas Storage Report of the methodology report.
