The U.S. Energy Information Administration reported a net 81-Bcf injection into natural gas inventories in the Lower 48 during the week ended May 26 that was above market expectations and mixed against historical averages.
The data included a reclassification of 4 Bcf from working gas to base gas in the Mountain region that resulted in an implied flow of 85 Bcf for the week under review.
The injection beat both the market consensus ahead of the report's release that called for a 75-Bcf build in stocks and the 80-Bcf injection reported for the same week in 2016, but missed the five-year average injection of 97 Bcf.
The build brought total U.S. working gas supply to 2,525 Bcf, or 370 Bcf below the year-ago level and 225 Bcf above the five-year average storage level of 2,300 Bcf.
