2017 Natural Gas Annual Summary

Core Content Overview

The Natural Gas Annual 2017 is a comprehensive report by the U.S. Energy Information Administration (EIA) that provides detailed data on the supply, movement, storage, and consumption of natural gas across the United States and its states. It is intended for a wide audience including Congress, federal and state agencies, industry analysts, consumers, and educational institutions.

The report presents data in a structured manner, following the flow of natural gas from production to end use. It includes national and state-level summaries for the period 2013–2017, with a focus on production, imports, exports, storage, and consumption. Key data is presented in tables and figures, which are organized by sector and geographic region.

Main Points

• Data Sources: The report primarily uses data from EIA surveys, including mandatory forms such as EIA-176, EIA-914, EIA-857, and EIA-910. Additional data is sourced from state and federal agencies, public record databases, and commercial vendors when necessary.
• Data Revisions: The 2017 report includes revised data from the 2016 series, particularly for production volumes and data series derived from EIA-176.
• Natural Gas Production: The report details the production of natural gas by state and by type of well (e.g., gas wells, oil wells, coalbed wells, shale gas wells). Production volumes declined in 2016 but increased in 2017.
• Marketed Production: Marketed production, which is the total production minus non-marketed volumes (repressuring, vented/flared, and nonhydrocarbon gases removed), is also reported.
• Imports and Exports: The report includes statistics on natural gas imports and exports by point of entry and exit, as well as average prices for these transactions.
• Underground Storage: Information on underground storage, including injections, withdrawals, and capacities, is presented for each state.
• Consumption by Sector: Natural gas consumption is broken down by residential, commercial, industrial, and electric power sectors. Data on the average price per thousand cubic feet is provided for each sector.
• Consumer Prices: The report includes citygate prices and prices delivered to consumers, which reflect the cost of natural gas at various points in the supply chain.
• State Summaries: Each state has its own summary table detailing production, consumption, and other related metrics, along with a section on the distribution of natural gas supply and disposition.

Key Information

Production (Million Cubic Feet)

• Total Gross Withdrawals (2013–2017): Declined significantly in 2016 but increased in 2017.
