  2. Pumpjack - Wikipedia

    en.wikipedia.org/wiki/Pumpjack

    A diagram of a pumpjack. 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.

  4. Centrifugal pump selection and characteristics - Wikipedia

    en.wikipedia.org/wiki/Centrifugal_pump_selection...

    Pump Characteristic curve; the head produced reduces with the discharge of the pump. Pump curves are quite useful in the pump selection, testing, operation and maintenance. Pump performance curve is a graph of differential head against the operating flow rate. They specify performance and efficiency characteristics.

  5. Oil well - Wikipedia

    en.wikipedia.org/wiki/Oil_well

    The pumpjack, such as this one located south of Midland, is a common sight in West Texas. An oil well is a drillhole boring in Earth that is designed to bring petroleum oil hydrocarbons to the surface. Usually some natural gas is released as associated petroleum gas along with the oil. A well that is designed to produce only gas may be termed a ...

  6. Fracking - Wikipedia

    en.wikipedia.org/wiki/Fracking

    Hydraulic fracturing [a] is a well stimulation technique involving the fracturing of formations in bedrock by a pressurized liquid. The process involves the high-pressure injection of "fracking fluid" (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore to create cracks in the deep rock formations through which natural gas, petroleum ...

    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.
