Greenhouse Gas Reporting Program (GHGRP)

GHGRP 2012: 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.
  • Natural Gas Processing. Processing of field quality gas to produce pipeline quality natural gas.
  • Natural Gas Transmission. Compressor stations used to transfer natural gas through transmission pipelines.
  • Underground Natural Gas Storage. Facilities that store natural gas in underground formations.
  • Natural Gas Distribution. Distribution systems that deliver natural gas to customers.
  • Liquified Natural Gas (LNG) Import/Export. Liquified Natural Gas import and export terminals.
  • LNG Storage. Liquified Natural Gas storage equipment.
