Form EIA-176, "Annual Report of Natural and Supplemental Gas Supply and Disposition"

  • Background on "Natural Gas Annual" data
  • Natural Gas Survey Forms and Instructions

  •   Explanatory Notes

  • Gas in storage at the end of a reporting period may not equal the quantity derived by adding or subtracting net injections or withdrawals during the period to the quantity of the gas in storage at the beginning of the period. This is due to changes in the quantities of native gas included in base gas and/or losses in base gas due to migration from storage reservoirs.
  • Totals may not equal sum of components due to independent rounding.
  • Geographic coverage is the 50 States and the District of Columbia. Prior to January 2013, Alaska data were not included in U.S. totals.
  • Positive net withdrawals indicate the volume of withdrawals in excess of injections. Negative net withdrawals indicate the volume of injections in excess of withdrawals.
