For the week ending September 23rd, the Energy Information Administration (EIA) reported that storage built by 49 billion cubic feet (bcf), ending the week at 3,600 bcf, 2.6% higher than a year ago, and 6.5% higher than its 5-year average.
Based on my regression, this implies a build of 80 bcf for (next) week. Storage should be reported around 3,680 bcf in this week's report.
