C=Reclassification Reclassifications from working gas to base gas resulted in decreased working gas stocks of 1 Bcf in the Pacific region and 2 Bcf in the South Central Salt region for the week ending April 5, 2019. The implied flow for the week is an increase of 29 Bcf to working gas stocks. (See Notes and Definitions for more information on "implied flow.") Totals may not equal sum of components because of independent rounding. |
Summary
Working gas in storage was 1,155 Bcf as of Friday, April 5, 2019, according to EIA estimates. This represents a net increase of 25 Bcf from the previous week. Stocks were 183 Bcf less than last year at this time and 485 Bcf below the five-year average of 1,640 Bcf. At 1,155 Bcf, total working gas is within the five-year historical range.
