Beginning with 2006, "Other States" volumes for the production series include the following states/areas: Alabama, Arizona, Federal Offshore Pacific, Florida, Idaho, Illinois, Indiana, Kentucky, Maryland, Michigan, Mississippi, Missouri, Nebraska, Nevada, New York, Oregon, South Dakota, Tennessee, and Virginia. Before 2017, Federal Offshore Pacific is included in California not "Other States". Production series data for 2018 forward are estimates. Final 2018 state-level production series data will not be available until the 2018 Natural Gas Annual is published (scheduled for the third quarter of 2019). Gross withdrawal volumes in Florida fluctuate from year to year because nonhydrocarbon gases are occasionally included in gross withdrawals.
