Report Summary
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. The "net change" in reported stock levels reflects all events affecting working gas in storage, including injections, withdrawals, and reclassifications between base and working gas. The "implied flow" estimate represents movements of working natural gas into or out of underground natural gas storage facilities that excludes reportable reclassifications-those totaling 4 billion cubic feet (Bcf) or more-from the weekly "net change" in working natural gas. An example of implied flow can be see for the report from July 17, 2015. The "implied flow" may contain the effects of unpublished net revisions to working natural gas levels of less than 4 Bcf. Totals may not match sum of components because of independent rounding.
