Natural Gas Monthly Summary - April 2018

Core Content

The Natural Gas Monthly report provides monthly estimates of natural gas production, consumption, and price data for the United States, covering the period from 2013 to 2018. It is published by the U.S. Energy Information Administration (EIA), an independent agency under the U.S. Department of Energy. The report includes both national and state-level data and is supported by various data collection methods and surveys conducted by the EIA.

Main Sections

Highlights: Contains state and national-level estimates of natural gas volume and price data through February 2018.
Common Abbreviations: Lists abbreviations used in the report for clarity.
Appendices: Includes explanatory notes, data sources, and statistical considerations.
Glossary: Provides definitions of terms used in the report.
Tables: Summarizes data on supply and consumption, prices, production, and storage.
Figures: Visual representations of data trends in production, consumption, and prices.

Key Information

Data Collection and Reporting

Data is collected through surveys and reports from various sources, including state and federal agencies, and the EIA.
The geographic coverage is the 50 U.S. states and the District of Columbia.
All natural gas volumes are reported at a pressure base of 14.73 psia and at 60°F.
Cubic feet are converted to cubic meters using a factor of 0.02831685.

Data Sources and Methodology

The Data Sources section explains the origins of the data used in the report.
The Statistical Considerations section provides information on the methodologies used for estimation and computation.
The Explanatory Notes supplement the data in tables and clarify the data collection procedures.

Natural Gas Supply and Disposition

Table 1 provides a summary of natural gas supply and disposition, including gross withdrawals, marketed production, NGPL production, dry gas production, supplemental gaseous fuels, net imports, net storage withdrawals, balancing item, and consumption.
For the years 2013–2015, the data is final, while for 2016–2018, it is preliminary unless otherwise indicated.
The balancing item represents data imbalances and losses.

Natural Gas Consumption

Table 2 outlines the consumption of natural gas by different sectors, including lease and plant fuel use, pipeline and distribution use, and deliveries to residential, commercial, industrial, and electric power consumers.
Consumption data is also broken down by the heating value of the natural gas used, reported in Btu per cubic foot.

Natural Gas Prices

Table 3 presents selected national average natural gas prices, including NGPL composite spot price, natural gas spot price, citygate price, and delivered prices to consumers.
Prices are categorized by residential, commercial, industrial, and electric power sectors, along with the percentage of total deliveries included in each price estimate.
The Electric Power Price is also provided.

Key Trends and Observations

Production: Natural gas production has shown a general upward trend from 2013 to 2018, with variations by month.
Consumption: Consumption data reflects the distribution across different sectors, with the majority going to residential, commercial, and industrial uses.
Prices: National average prices for natural gas and NGPL have fluctuated over the years, with residential and industrial prices showing notable changes.
Storage: Underground natural gas storage data is reported and includes seasonal variations and different types of storage fields, such as salt caverns and other storage fields.
