The top altitude of this aquifer is called the "water table", below which the ground and rock has all the spaces and voids full of water.

ARTESIAN WELL. Groundwater in aquifers between layers of poorly permeable rock, such as clay or shale, may be confined under pressure. If such a confined aquifer is tapped by a well, water will rise above the top of the aquifer and may even flow from the well onto the land surface. Water confined in this way is said to be under artesian pressure, and the aquifer is called an artesian aquifer.

Deep wells drilled into rock to intersect the water table and reaching far below it are often called artesian wells in ordinary conversation, but this is not necessarily a correct use of the term. Such deep wells may be just like ordinary, shallower wells; great depth alone does not automatically make them artesian wells. The word artesian, properly used, refers to situations where the water is confined under pressure below layers of relatively impermeable rock.

Artesian wells can be sometimes flow to the land surface naturally because of underground pressure.

Generally, the upper layer of an aquifer system is the unconfined aquifer, which does not have a confining layer of solid material above it. The top altitude of this aquifer is called the "water table", below which the ground and rock has all the spaces and voids full of water. Water from this aquifer must be pumped out in a well to get to the land surface.

In some locations confined aquifers can exist below the unconfined aquifers. These confined aquifers have layers of solid material above and below them and are under pressure from the rock weight. For water to recharge these aquifers, it much seep down from the surface at a distance away and travel somewhat horizontally into the confined aquifer.

If this level is below the land surface altitude (the right side artesian well in the diagram) the water will not shoot out of the well at the land surface...the well is called an artesian well. If the piezometric level is higher than the well head altitude at the land surface (the artesian well on the left-side of the diagram), the water will be pushed upward in the well and emerge at the land surface, with no pump needed. This kind of well is a flowing artesian well. (1)
