They're both different in many ways but similar in some.
That depends how deep the well was dug or drilled.
The water in artesian wells is under pressure - or at least was when the well was dug.
When the well is drilled, it is dug or drilled through the water-sand, and as the water flows into the well from the sand, it is cleaned by the sand, which acts as a filter.
No. The deepest hole ever drilled only made it a few miles into the crust before the heat stopped the equipment from working properly.
They are supposed to be dug deep enough to supply a constant source of water. however they will dry up if the water table falls below the depth of the well. This can happen if water is sucked form the well too fast (draw-down issue), if there is a prolonged regional drought (catchment/replenishment issue) and if too many wells are dug into the aquifer (over extraction issue).

it was dug by hand or drilled
The first oil wells were drilled in China in 347 A.D. using bamboo poles. In Persia hand dug wells reached depths of 115 feet in 1594. The first modern well was drilled in Russia in 1848, and in 1859 Colonel Edwin Drake drilled the first US oil well for commercial oil production, at Titusville, PA; it was 69 feet deep.
Newer water wells are drilled, which produces a circular cross section. Older wells were dug by hand. It is not that easy to make a square hole - corners are kind of tricky, especially when you're working in close quarters with a shovel.
you had your garden dug says someone else dug your garden, while you dug your garden says you dug it.

By hand.
He dug wells.
This is due to evaporation. Wells get dry.
