Oil well pump jack for oil production

3docean

The oil well pump jack is a machine that extracts crude oil from underground reservoirs for use as fuel. It works by repeatedly drawing up and then pushing down on the oil, creating pressure to bring it to the surface. The motion of the pump jack creates suction which pulls oil out of the wellbore, allowing it to flow through the well tubing into a collection system. In modern oil production, pump jacks are used to extract oil from wells that are no longer economically viable using other methods such as drilling new wells or injecting fluids into the reservoir to increase pressure.
