Working gas storage in the contiguous US totalled 2,953 bill cu ft in the week ending 27th June, a net increase of 55 bill cu ft from the previous week, the US Energy Information Administration (EIA) said in a report.
The total working gas storage declined by 5.6% from the same time last year, but was up by 6.2% from the five-year average, according to the EIA's Weekly Natural Gas Storage Report.
The storage of US working gas usually tends to decrease in November and continues to drop in April when the heating season ends, according to previous data.
Working gas is defined as the amount of natural gas stored underground that can be withdrawn for use. Its storage capacity can be measured in two ways: design capacity and demonstrated maximum working gas capacity.
The contiguous US consists of the country's 48 adjoining states plus the District of Columbia, and excludes the non-contiguous states of Alaska and Hawaii and all offshore insular areas.
