GHGRP 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.
- Liquefied Natural Gas (LNG) Import/Export. Liquefied Natural Gas import and export terminals.
- LNG Storage. Liquefied Natural Gas storage equipment.
- Other Petroleum and Natural Gas Systems. Stationary fuel combustion emissions from petroleum and natural gas source categories that are not otherwise listed.

1 The Southern California Gas Company - Aliso Canyon facility’s actual 2015 emissions were higher than those reported to the GHGRP. The GHGRP provides well-vetted average emission factors to calculate emissions. The facility followed these GHGRP calculation methods for 2015 reporting. Actual emissions differ from those reported due to an exceptional leak event. See California Air Resource Board’s Aliso Canyon Natural Gas Leak Exitwebpage for more information.
