  2. Water well pump - Wikipedia

    en.wikipedia.org/wiki/Water_well_pump

    These pumps, often submersible and powered by electricity, can access water reserves located much deeper than shallow wells, ensuring a consistent supply even during periods of drought. They include different kinds of pumps, most of them submersible pumps: Hand pump, manually operated; Injector, a jet-driven pump; Mechanical or rotary lobe pump ...

  3. Injector - Wikipedia

    en.wikipedia.org/wiki/Injector

    The S type pump is useful for removing water from a well or container. Shallow well pumps are those in which the jet assembly is attached directly to the main pump and are limited to a depth of approximately 5-8m to prevent cavitation. Deep well pumps are those in which the jet is located at the bottom of the well. The maximum depth for deep ...

  4. Artificial lift - Wikipedia

    en.wikipedia.org/wiki/Artificial_lift

    Artificial lift is the use of artificial means to increase the flow of liquids, such as crude oil or water, from a production well. Generally this is achieved by the use of a mechanical device inside the well (known as pump or velocity string) or by decreasing the weight of the hydrostatic column by injecting gas into the liquid some distance down the well.

  5. Pump-jet - Wikipedia

    en.wikipedia.org/wiki/Pump-jet

    A pump-jet, hydrojet, or water jet is a marine system that produces a jet of water for propulsion. The mechanical arrangement may be a ducted propeller (axial-flow pump), a centrifugal pump, or a mixed flow pump which is a combination of both centrifugal and axial designs. The design also incorporates an intake to provide water to the pump and ...

  6. Well - Wikipedia

    en.wikipedia.org/wiki/Well

    A well is an excavation or structure created on the earth by digging, driving, or drilling to access liquid resources, usually water. The oldest and most common kind of well is a water well, to access groundwater in underground aquifers. The well water is drawn up by a pump, or using containers, such as buckets that

  7. Drilling fluid - Wikipedia

    en.wikipedia.org/wiki/Drilling_fluid

    Synthetic-based fluid poses the same environmental and analysis problems as oil-based fluid. [ 7 ] On a drilling rig , mud is pumped from the mud pits through the drill string, where it jets out of nozzles on the drill bit, thus clearing away cuttings and cooling the drill bit in the process.

  8. 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.

  9. Blowout preventer - Wikipedia

    en.wikipedia.org/wiki/Blowout_preventer

    The U.S. government wanted the failed blowout preventer to be replaced in case of any pressure change that occurs when the relief well intersected with the well. [14] On September 3, 2010, at 1:20 p.m. CDT the 300 ton failed blowout preventer was removed from the well and began being slowly lifted to the surface. [ 14 ]
