A pumpjack is the overground drive for a reciprocating piston pump in an oil well. [1] It is used to mechanically lift liquid out of the well if there is not enough bottom hole pressure for the liquid to flow all the way to the surface. The arrangement is often used for onshore wells. Pumpjacks are common in oil-rich areas.

A pump jack is a device used in the petroleum industry to extract crude oil from a oil well where there is not high enough pressure in the well to force the oil to the surface. These pump jacks physically extract the oil for use. [2] . Pump jacks and oil …

What is a pump jack? A pump jack is a widely recognized piece of equipment used to pump crude oil from underground reservoirs. How Does a pump jack work? Producers use pump jacks as …

Jun 10, 2021 · Pumpjacks are classified as artificial lift system and are used in oil wells that don’t have enough pressure for oil to naturally rise to the surface. They’re often also used to lift water out of gas wells to improve gas inflow. (a.k.a. “waterjerkers”).

Mar 14, 2016 · Pumpjack (also known as donkey pumper, oil horse, pumping unit, nodding donkey) is overground drive for reciprocating the piston pump in oil well.

Let’s take a look at pumpjacks: how they are built, how they function, and how much oil they actually produce. Where did pumpjacks come from? After Edwin Drake built the first oil well around 1859 (check out our history of oil article for more information), effort went into designing systems to artificially lift petroleum from the ground.

Dec 31, 2024 · A pumpjack is a mechanical device used in the oil industry to extract crude oil from underground wells. It creates an up-and-down motion to pump oil to the surface when natural …

Jan 11, 2025 · This image illustrates the components and operation of a pumpjack, which is a mechanical device used to extract oil from wells when reservoir pressure is insufficient to push the oil to the surface.

A pumpjack lifts liquid - typically an emulsion of crude oil and water - out of the well to be refined and then placed on the global market. Modern pumpjacks are powered by an engine known as a prime mover.

The pumpjack or oil pumping unit is the surface equipment used when pumping oil with the rod pump. It converts the high-speed rotation of the surface power machinery into low-speed reciprocating motion, driving the downhole pump to work through the sucker rod.
