Beginning with 2006, "Other States" volumes for the production series include the following states/areas: Alabama, Arizona, Florida, Idaho, Illinois, Indiana, Kentucky, Maryland, Michigan, Mississippi, Missouri, Nebraska, Nevada, New York, Oregon, South Dakota, Tennessee, and Virginia. Federal Offshore Pacific is included in California through 2017, and in "Other States" starting in 2018. 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.
