oil and gas industry
The petroleum industry, also known as the oil industry or the oil patch, includes the global processes of exploration, extraction, refining, transportation (often by oil tankers and pipelines), and marketing of petroleum products. The largest ...
is usually divided into three major components:
upstream
Upstream may refer to:
* Upstream (bioprocess)
* ''Upstream'' (film), a 1927 film by John Ford
* Upstream (networking)
* ''Upstream'' (newspaper), a newspaper covering the oil and gas industry

and deliver the various refined products to downstream distributors. Natural gas pipeline networks aggregate gas from
natural gas purification plants and deliver it to downstream customers, such as local utilities.
The midstream operations are often taken to include some elements of the upstream and downstream sectors. For example, the midstream sector may include
natural gas processing
Natural-gas processing is a range of industrial processes designed to purify raw natural gas by removing impurities, contaminants and higher molecular mass hydrocarbons to produce what is known as ''pipeline quality'' dry natural gas. Natural gas ...
plants that purify the raw natural gas as well as removing and producing
elemental sulfur and
natural gas liquids (NGL) as finished end-products.
