C=Reclassification Non-flow-related adjustments decreased working gas stocks by approximately 5 Bcf in the South Central Nonsalt region for the week ending October 19, 2018. The implied flow for the week is an injection of 63 Bcf to working gas stocks in the Lower 48 states. (See Notes and Definitions for more information.) Starting with the Weekly Natural Gas Storage Report (WNGSR) release on Thursday, November 15, 2018, the WNGSR history file will include a new worksheet showing the net change for each report week. You can view the new format in this test file. Totals may not equal sum of components because of independent rounding. |
