Greenhouse Gas Reporting Program (GHGRP)

GHGRP 2016: Petroleum and Natural Gas Systems

 This sector consists of the following industry segments of the petroleum and natural gas industry.

  • Onshore Production. Production of petroleum and natural gas associated with onshore production wells and related equipment.
  • Offshore Production. Production of petroleum and natural gas from offshore production platforms.
  • Gathering and Boosting. Gathering pipelines and other equipment that collect petroleum/natural gas from onshore production gas or oil wells and then compress, dehydrate, sweeten, or transport the petroleum and/or natural gas.
  • Natural Gas Processing. Processing of field quality gas to produce pipeline quality natural gas, and fractionation of gas liquids.
  • Natural Gas Transmission Compression. Compressor stations used to transfer natural gas through transmission pipelines.
  • Natural Gas Transmission Pipeline. A rate-regulated interstate or intrastate pipeline, or a pipeline that falls under  the "Hinshaw Exemption" of the Natural Gas Act.
  • Underground Natural Gas Storage. Facilities that store natural gas in underground formations.
  • Liquefied Natural Gas (LNG) Import/Export. Liquefied Natural Gas import and export terminals.
  • LNG Storage. Liquefied Natural Gas storage equipment.
  • Natural Gas Distribution. Distribution systems that deliver natural gas to customers.
  • Other Petroleum and Natural Gas Systems. Stationary fuel combustion emissions from petroleum and natural gas source categories that are not otherwise listed.

a Facilities in the Gathering and Boosting and Transmission Pipeline industry segments began reporting in 2016.

Totals may not equal sum of individual GHGs due to independent rounding.

CO2 emissions from the combustion of biomass are NOT included in emissions totals provided above.
