2. Pumpjack - Wikipedia

   en.wikipedia.org/wiki/Pumpjack

   Pump size is also determined by the depth and weight of the oil to remove, with deeper extraction requiring more power to move the increased weight of the discharge column (discharge head). A beam-type pumpjack converts the rotary motion of the motor (usually an electric motor ) to the vertical reciprocating motion necessary to drive the ...

3. Gas lift - Wikipedia

   en.wikipedia.org/wiki/Gas_lift

   These systems used single point injection of air into the liquid stream, normally through a foot valve at the bottom of the string. Gas lift was used as early as 1864 in Pennsylvania to lift oil wells, also using compressed air, via an air pipe bringing the air to the bottom of the well. Air was used in Texas for large-scale artificial lift.

4. Pneumatic lubricator - Wikipedia

   en.wikipedia.org/wiki/Pneumatic_lubricator

   A pneumatic lubricator injects an aerosolized stream of oil into an air line to provide lubrication to the internal working parts of pneumatic tools, and to other devices such as actuating cylinders, valves, and motors. Compressed air enters the inlet port and passes over a needle valve orifice attached to a pick-up tube.

5. Dry sump - Wikipedia

   en.wikipedia.org/wiki/Dry_sump

   The oil collects in sump (1), is withdrawn continuously by scavenge pump (2) and travels to the oil tank (3), where gases entrained in the oil separate and the oil cools. Gases (6) are returned to the engine sump. Pressure pump (4) forces the de-gassed and cooled oil (5) back to the engine's lubrication points (7).

6. Extraction of petroleum - Wikipedia

   en.wikipedia.org/wiki/Extraction_of_petroleum

   When oil and gas are burned they release carbon dioxide into the air. Fossil fuels, such as oil, are responsible for 89% of the CO2 emissions. [10] Carbon emissions cause climate change which negatively impacts people's safety by raising sea levels and worsening weather. Oil can also cause oil spills, which pollutes the ocean. [10]

7. Comparison of pumps - Wikipedia

   en.wikipedia.org/wiki/Comparison_of_pumps

   Different types of pumps are suitable for different applications, for example: a pump's maximum lift height also determines the applications it can be used for. Low-lift pumps are only suitable for the pumping of surface water (e.g., irrigation, drainage of lands, ...), while high-lift pumps allow deep water pumping (e.g., potable water pumping ...
