Diagram of a water well partially filled to level z with the top of the aquifer at z T. For a well with impermeable walls, the water in the well is resupplied from the bottom of the well. The rate at which water flows into the well will depend on the pressure difference between the ground water at the well bottom and the well water at the well ...
A tube well is a type of water well in which a long, 100–200 millimetres (3.9–7.9 in)-wide, stainless steel tube or pipe is bored underground. The lower end is fitted with a strainer, and a pump lifts water for irrigation. The required depth of the well depends on the depth of the water table.
Well, the condition of having a high level of well-being; Well, good health; Gravity well or gravitational, a conceptual model of the gravitational field surrounding a body in space; Potential well, a concept used in physics related to kinetic energy; Quantum well, a potential well with only discrete energy values
Intelligent well: An oil or gas well equipped with monitoring equipment and completion components that allow for automatic or remote optimization of production. Joint: A length of pipe. Kelly: A square or hexagon pipe ( Approximately 40 ft. long ) used to turn the drill string while drilling.

A Ranney Collector is a type of radial well used to extract water from an aquifer with direct connection to a surface water source like a river or lake. The amount of water available from the collector is typically related more to the surface water source than to the piezometric surface of the aquifer. [1]
An artesian well is a well that brings groundwater to the surface without pumping because it is under pressure within a body of rock or sediment known as an aquifer. [1] When trapped water in an aquifer is surrounded by layers of impermeable rock or clay, which apply positive pressure to the water, it is known as an artesian aquifer. [1]
From 2011 until August 2012 the record was held by the 12,345-metre (40,502 ft) long Sakhalin-I Odoptu OP-11 Well, offshore the Russian island Sakhalin. [11] The Chayvo Z-44 extended-reach well took the title of the world's longest borehole on 27 August 2012. Z-44's total measured depth is 12,376 metres (40,604 ft).
