  2. Pressure tank - Wikipedia

    en.wikipedia.org/wiki/Pressure_tank

    Case 1 is an empty tank at the charging pressure P c (gauge). The total volume of the tank is V t. Case 2 is a tank in use, with the air pressure at pressure P (gauge) and a water volume of V. Referring to the diagram on the right, a pressure tank is generally pressurized when empty with a "charging pressure" P c, which is usually about 2 psi ...

  3. Pumpjack - Wikipedia

    en.wikipedia.org/wiki/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. Coiled tubing - Wikipedia

    en.wikipedia.org/wiki/Coiled_tubing

    Below the injector is the stripper, which contains rubber pack off elements providing a seal around the tubing to isolate the well's pressure. Below the stripper is the preventer, which provides the ability to cut the coiled tubing pipe and seal the well bore (shear-blind) and hold and seal around the pipe (pipe-slip). Older quad-BOPs have a ...

  5. Pumping (oil well) - Wikipedia

    en.wikipedia.org/wiki/Pumping_(oil_well)

    In the context of oil wells, pumping is a routine operation involving injecting fluids into the well. Pumping may either be done by rigging up to the kill wing valve on the Xmas tree or, if an intervention rig up is present pumping into the riser through a T-piece (a small section of riser with a connection on the side).

  6. 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 ...
