Monthly Natural Gas Production Report with data for April 2009
Released: June 30, 2009
Next Release: July 31, 2009

Data presented in the table below are monthly natural gas gross withdrawals estimated from data collected on the EIA-914 survey. Gross withdrawals are converted to marketed natural gas production which is reported on the EIA website in the Natural Gas Navigator, and in the Natural Gas Monthly and Annual reports. Marketed production is calculated by subtracting gas used for repressuring, quantities vented and flared, and nonhydrocarbon gases removed in treating or processing operations from gross withdrawals.

Production for the lower 48 States declined 0.2 percent in April despite production gains from new wells in Louisiana (up 3 percent) and the Federal Offshore Gulf of Mexico (up 1 percent). Wyoming and Texas had the largest declines at about 1 percent each, as wellhead prices continued to decline and several natural gas plants shut down in Texas.

All estimates, except as footnoted, are based on the adjusted ratio estimate method, which is explained in the Background and Methodology report. Readers are encouraged to review these reports to better understand all aspects of the EIA-914 survey. The Data Files contain initial and revised production estimates for each month (revisions are based on company resubmissions and late reports) and response rates by month.

Note about 2009 Natural Gas Production

January 2009 gross natural gas production estimates reported here are based on data from the regularly updated annual sample of natural gas well operators selected to report on Form EIA-914. Along with the introduction of the updated sample, the calibration year used for estimation has also been updated in accordance with the published methodology (see http://www.eia.doe.gov/oil_gas/natural_gas/data_publications/eia914/eia914meth.pdf). Due to the combined effects of the changes in sample and calibration period, the production estimates for December 2008 and January 2009 are not comparable for some States. Apparent changes in estimated production may, in some cases, be due entirely to the sample and calibration changes. To prevent future breaks in the series, EIA is undertaking a comprehensive review of all aspects of the Form EIA-914 methodology. Revisions to the estimates provided here, along with documentation of the methodological changes, will be published as appropriate in light of that review.

1 The estimates are based on the adjusted ratio method, explained in the Background and Methodology report.
2 Texas gross withdrawals data do not include CO2 production associated with injection projects.
 Texas CO2 Adjustment Article
3 Monthly Other States total estimates determined by applying the ratio of 2006 total gross natural gas production published in the EIA Natural Gas Navigator to the 2006 EIA-914 survey production.

R=Revised data. It is EIA-914's revision policy to revise the prior month's data for any change when the latest month's data is released. Earlier months are only revised when a current estimate differs by the amount specified in the Revision Policy.

Note: New Mexico EIA-914 gross withdrawals estimates now include CO2 production in the same manner as it is reported by the State of New Mexico. All associated EIA-914 Data Files have been updated.
Area estimates may not add to the Lower-48 estimate due to independent rounding.
