An artesian aquifer is a confined aquifer containing groundwater under positive pressure. An artesian aquifer has trapped water, surrounded by layers of impermeable rock or clay which apply positive pressure to the water contained within the aquifer. If a well were to be sunk into an artesian aquifer, water in the well-pipe would rise to a height corresponding to the point where hydrostatic equilibrium is reached.

What do you need exactly? Because it is called an artesian well when groundwater flow can overflow the well, sometimes flowing outward at the surface! This is because the GW is under the pressure of an impermeable stratum and when a well is drilled, the water is released with a hydraulic potential higher than the atmospheric pressure. Is this the case?
Because people called artesian well to any well without this knowledge. Regards. Dr. Miguel Rangel
