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.
The complexity of the pumps is a fundamental problem for all programs of this kind, as well as the quality of the pumps given the heavy demands of a village. [20] A 1994 study, also Bank funded, of the endurance of hand pumps in Africa showed that only 41 to 51 percent of hand pumps were still functioning. [ 20 ]
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 ...
For maintenance or replacement, submersible pumps are raised by a chain off of the duckfoot and up the two guide rails to the maintenance (normally ground) level. Reinstalling the pumps simply reverses this process with the pump being remounted on the guide rails and lowered onto the duckfoot where the weight of the pump reseals it.
Convicted Delphi, Indiana, killer Richard Allen was sentenced on Friday to 130 years in prison for the 2017 murders of two teenage girls as the victims' families spoke out in court. Allen, wearing ...
Rodgers is currently wrapping up his second season with the Jets, a tenure that has seen the team go 4-11 with him under center after he missed all of last year with a torn Achilles.
Rep. Mike Lawler argued on Sunday that Republicans considering voting against House Speaker Mike Johnson for another term are “playing with fire.”
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).
