EIA will begin publishing estimates based on a new sample selected for the Weekly Natural Gas Storage Report(WNGSR) on September 13, 2018, with the report for the week ending September 7, 2018. On Monday, September 10, 2018, EIA will revise estimates for the eight weeks covering July 13, 2018, through August 31, 2018, to gradually phase in the estimates from the new sample. Although the established sampling and estimation methodologies for the WNGSR have not changed, estimates produced from the new sample will reflect the most recent version of the EIA's Form EIA-912, which requires storage operators in the South Central region to separately report the volume of working natural gas held in salt facilities and nonsalt facilities. For additional information, please see the notice of changes to the WNGSR: http://ir.eia.gov/ngs/notice.html
