Natural Gas Monthly Summary (August 2018)

Core Content

The Natural Gas Monthly (NGM) report provides monthly estimates of natural gas volume and price data for the United States, covering production, consumption, imports, exports, and storage. It serves as a key resource for both public and private sector organizations involved in the natural gas industry. The data are collected through surveys conducted by the Energy Information Administration (EIA), and the report includes detailed tables, figures, and explanatory notes to support its findings.

Main Points

• Data Coverage: The report includes data from 2013 to 2018, with a focus on the period up to June 2018.
• Data Sources: Data are collected from various EIA forms and reports, including EIA-914, EIA-857, and EIA-191, as well as from state and federal agencies.
• Unit Conversion: All natural gas volumes are reported at a pressure base of 14.73 psia and a temperature of 60°F, with cubic feet converted to cubic meters using a factor of 0.02831685.
• Geographic Scope: The data cover the 50 U.S. states and the District of Columbia.
• Data Classification: The report distinguishes between different sectors such as residential, commercial, industrial, and electric power, and includes heating value data for natural gas.
• Data Accuracy: Some data are estimated, while others are revised or preliminary. Final data for 2013–2015 are noted, and other data are considered preliminary.
• Storage Data: Underground storage data are included for the years 2013–2018, with the exception that data for January 2017 onward include underground storage only.

Summary of Trends

• Production and Consumption: Natural gas production and consumption showed fluctuations over the years, with some months indicating a decrease in net imports and net storage withdrawals.
• Prices: Natural gas prices varied by sector and month, with residential and commercial prices showing a notable increase in 2017 and early 2018.
• Storage: Underground storage levels fluctuated, with notable withdrawals and injections depending on the month and year.

Conclusion

The Natural Gas Monthly report offers a comprehensive overview of U.S. natural gas activities, including production, consumption, and price trends, with a focus on the period up to June 2018. It is a valuable resource for understanding the dynamics of the natural gas market and is supported by detailed data sources, statistical considerations, and explanatory notes.
