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. Extraction of petroleum - Wikipedia

   en.wikipedia.org/wiki/Extraction_of_petroleum

   Tertiary recovery begins when secondary oil recovery is not enough to continue adequate extraction, but only when the oil can still be extracted profitably. This depends on the cost of the extraction method and the current price of crude oil. When prices are high, previously unprofitable wells are brought back into use, and when they are low ...

   en.wikipedia.org/wiki/Separator_(oil_production)

   Oil and gas separators can have three general configurations: vertical, horizontal, and spherical.Vertical separators can vary in size from 10 or 12 inches in diameter and 4 to 5 feet seam to seam (S to S) up to 10 or 12 feet in diameter and 15 to 25 feet S to S. Horizontal separators may vary in size from 10 or 12 inches in diameter and 4 to 5 feet S to S up to 15 to 16 feet in diameter and ...

6. Sucker rod - Wikipedia

   en.wikipedia.org/wiki/Sucker_rod

   The line of sucker rods is represented in this diagram by the solid black line in the center of the well. A sucker rod is a steel rod, typically between 7 and 9 metres (25 and 30 ft) in length, and threaded at both ends, used in the oil industry to join together the surface and downhole components of a reciprocating piston pump installed in an oil well.

7. 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   The oil collects in sump (1), is withdrawn continuously by scavenge pump (2) and travels to the oil tank (3), where gases entrained in the oil separate and the oil cools.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).

8. Gas lift - Wikipedia

   en.wikipedia.org/wiki/Gas_lift

   Airlift pumps use compressed air to lift water; Pulser pumps use a subterranean air chamber to lift underground water; Suction dredges use a variety of the gas lift called an airlift pump to vacuum mud, sand and debris; Mist lifts use vaporized water to draw seawater in ocean thermal energy conversion systems

9. Kimmeridge Oil Field - Wikipedia

   en.wikipedia.org/wiki/Kimmeridge_Oil_Field

   The Kimmeridge 1 well site, is a small site, with a single beam pump or "nodding donkey" which has been pumping continually since 1961, making it the oldest working oil pump in the UK. [2] The well once produced 350 barrels per day, but currently yields around 65 barrels per day (10.3 m 3 /d) from the Jurassic strata that lie around 350 metres ...
