Some natural gas storage operators have reported net withdrawals from base gas, beginning with the week ending April 6, 2018. The cumulative net withdrawals of base gas were treated as negative working gas stocks and are reflected in the working gas inventories. As a result, a small portion of this week's reported net change includes flows from base gas.

Summary

Working gas in storage was 1,299 Bcf as of Friday, April 13, 2018, according to EIA estimates. This represents a net decrease of 36 Bcf from the previous week. Stocks were 808 Bcf less than last year at this time and 449 Bcf below the five-year average of 1,748 Bcf. At 1,299 Bcf, total working gas is within the five-year historical range.
