A pumpjack (also called nodding donkey, pumping unit, horsehead pump, rocking horse, beam pump, dinosaur, sucker rod pump (SRP), grasshopper pump, thirsty bird, or jack pump) is the overground drive for a reciprocating piston pump in an oil well.
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 commonly used for onshore wells producing little oil. Pumpjacks are common in oil-rich areas.
