Definition - What does Pumping Well mean?
A Pumping Well is a well in which pumping is required to increase the formation pressure to allow the free production flow. It is the opposite of a naturally flowing well because in such type of a well an external device such as a reciprocating pump is used to force the liquid to move out of the well. Such type of pumps can be also referred as downhole pumps. The pressure measurement is done in the downhole using a well sounder, which is a sonic device.
Petropedia explains Pumping Well
Pumping is required when there is insufficient pressure in a well which restricts the flow of fluids. In the reservoirs where water is used as the driving force, pumping is not required, as the water does the work of a pump. However, in a Pumping Well, sonic devices are used to measure the liquid level or liquid rise in the well. It is based on the calculation of time taken by sound waves for travelling the downward distance and hitting the upper layer of the crude oil or natural gas inside a well. Based on the level of liquid, an external device such as a downhole pump can be used to pump out the hydrocarbons from the well.
