In March, Lower 48 States production decreased 0.6 percent or 0.41 billion cubic feet per day (Bcf/d). Louisiana had the largest decrease at 4.5 percent or 0.33 Bcf/d as several operators reported shut-ins for maintenance. The Gulf of Mexico also contributed to the decline with a decrease of 3.5 percent or 0.14 Bcf/d which was partially due to maintenance and pipeline issues. Oklahoma and Texas both had increases of 1.6 percent or 0.09 Bcf/d and 0.4 percent or 0.09 Bcf/d respectively, as new wells were brought online. New Mexico also increased 1.7 percent or 0.06 Bcf/d.

Note: Data presented in the table are monthly natural gas gross withdrawals estimated from data collected on the EIA-914 survey. In 2011, data are from the EIA Natural Gas Annual. Gross withdrawals are converted to marketed natural gas production which is reported on the EIA website in the Natural Gas Data Tables, and in the Natural Gas Monthly and Natural Gas 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.

1 The EIA-914 estimates are based on the simple ratio method, explained in the Methodology.
2 Texas gross withdrawals data do not include CO2 production associated with injection projects.  Texas CO2 Adjustment Article
3 2012-Forward monthly Other States total estimates are determined by applying the ratio of 2011 gross natural gas production published at http://www.eia.gov/dnav/ng/ng_prod_sum_a_EPG0_FGW_mmcf_a.htm to the 2011 reported EIA-914 survey production.
4 Alaska data is from the State of Alaska, not the EIA-914. It's included here for completeness.
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.
Notes: 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.

All estimates, except as footnoted, are based on the simple ratio estimate method, which is explained in the Methodology. 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. Data and graphs showing comparisons between EIA-914 estimates and other sources can also be found here.
