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.
- 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.
