| Oil pump. An oil pump,known as a jack pump or a "nodding donkey",showing it in motion. The pump draws oil out of the ground through a series of non-return valves (not shown here). Newly-drilled oil wells often contain oil at a high enough pressure to force the fluid out without needing to be pumped. As the oil is removed,the pressure falls. For a time,the pressure can be maintained by pumping water or air into the subterranean reservoir of oil. Eventually the pressure falls further and a jack pump is required bring oil out at an economic rate. Even using jack pumps,generally only 30-50 per cent of the oil can be extracted | |
