Water dowsing (searching for water with a forked stick for example) is a con pantomine. Water is almost abundantly available over all of the earth's surface. Rainfall or precipitation of some sort occurs most everywhere on the earth's surface. After rain hits the ground it starts a possible deep journey to a level which can be mapped in surface area that represents an underground reservoir. Many of the large reservoirs have been mapped for the United States since the 1930's, and a resource like a public library should be able to provide this printed information. One way to inexpensively find out how deep water is in a specific area is to ask the surrounding land owners. If you live in a mountainous area, take heart for good water can be found at various levels relatively near grade. Drilling to depths of around 300 feet is somewhat normal. Water can be found at several levels in one drill site. States have most of the legal requirements of underground water sources. Once water is available in adequate supply, a landowner should have it checked for how suitable it is for its intended purpose.

A well is basically a hole drilled deep into the ground until it reaches an aquifer, which is a body of rock that transmits water. Wells with electric pumps pump the water through pipes to it's destination.
Edwin Drake invented the oil drill and drilled the first oil well in history. By the time he died, Drake had drilled two more wells.
People drill wells to reach fresh water.
Irrigation depends on water which is taken from the wells,tube-wells, ponds, rivers to water the plants.

The name of a hole used to extract groundwater is called a well. Wells are drilled or dug into the ground to access and collect water from underground aquifers or water tables.
Dug wells are excavated by hand or machine, typically dug into the ground to access groundwater. Drilled wells are created using specialized equipment to bore deep into the ground to access groundwater. Drilled wells are typically deeper and can access water from greater depths compared to dug wells.
All 77 counties in Oklahoma have had oil wells drilled in them.

The number of wells drilled can vary each year based on industry demand and exploration efforts. In 2020, there were approximately 12,758 oil and gas wells drilled in the United States alone.
The depth of the water table determines how deep a well must be drilled to reach groundwater. Wells need to be drilled below the water table to ensure a consistent and sustainable water supply. If the water table is deep, wells will need to be drilled deeper to access the groundwater.
Typical sources of well water include underground aquifers, springs, and reservoirs that collect and store water beneath the Earth's surface. Wells are drilled down into these sources to access the water for residential, agricultural, and industrial use.
Water can be extracted from the ground through wells. Wells are drilled or dug deep into the ground until they reach a water source such as an aquifer. Once the well is constructed, a pump is used to bring the water to the surface for use.
This question is impossible to answer, as wells are being drilled continuously.
Drilled Hole: a deep hole drilled into the ground to obtain samples for geological study or to release or extract water or oil Usually narrow in width. Probably the most common type is a water borehole, which is where the borehole is used as a water well.
Mostly towns sink wells for drinking water. If they draw off too much water for precipitation, etc. to refill then they cause the water table to fall and the wells will be drilled deeper and the water table will fall more.
