NOTE TO EDITORS:

Discussion of the Sample Changes for the Weekly Natural Gas Storage Report

This special report provides details on the recent change in the survey sample for the EIA-912 survey, “Weekly Underground Natural Gas Storage Report.” The transition from the old to the new sample began with the release of the Weekly Natural Gas Storage Report on May 22, 2008, and was complete with the release of June 12, 2008 (the affected working gas estimates were for weeks ending May 16, 2008, through June 6, 2008). Prior to implementation of the new sample in the published estimates, both samples were used in parallel to estimate weekly natural gas storage stocks from May 4, 2007, through May 9, 2008. This report describes a change in sampling procedure for the current sample and examines the differences between results from the old and new samples. The results are compared with the monthly data from the EIA-191 survey, as well as with each other. The report, Discussion of the Sample Changes for the Weekly Natural Gas Storage Report, is available at:
