| Gas Gathering |
|
Compressors are used in gas gathering applications for compressing natural gas produced from individual wells and other sources. The gas is stored or gathered through a network of pipelines and travels through a central pipeline to a designated location. This example below shows a scheme where natural gas produced from individual wells is gathered and compressed. The natural gas may be gathered from several different sources, such as a gas well, an associated gas and casing head gas, produced from an individual oil well, or gathered from other production facilities.

| Gas Injection |
|
Gas Injection is a widely used secondary recovery method for oil production. It is one form of oil reservoir pressure maintenance operation, where produced gas is injected into the formation, through gas injection wells. This builds up the formation pressure high enough to force oil and gas to the surface through oil producing wells. The gas produced is recaptured and re-injected. The oil produced is collected for further processing and refining.

| Gas Lift |
|
Gas lift is one form of artificial lift systems, widely used to supplement the natural formation energy, enabling the oil well to produce. Casing head gas and or associated gas is gathered, compressed and injected into the oil well casing. The injected gas then passes through gas lift mandrels and valves that are installed at various elevations of the production tubing string, lowering the hydrostatic pressure of the oil column, thus causing the oil to flow. The gas is then recovered and re-injected into the casing again. The oil produced is collected for further processing and refining.
