A deep hole or shaft sunk into the Earth to tap a liquid or gaseous substance such as water, oil, gas, or brine. If the substance is not under sufficient pressure to flow freely from the well, it must be pumped or raised mechanically to the surface. Water or pressurized gas is sometimes pumped into a nonproducing oil well to push petroleum resources out of underground reservoirs. See also artesian well. |
Wells
city, Mendip district, administrative and historic county of Somerset, England, at the foot of the Mendip Hills. The name derives from the many springs rising near the cathedral, which was begun in the 12th century and dominates the city. In general, Wells has been little affected by modern industry and growth. It remains a modest service centre, its Market Place and shopping district lying in the shadow of its magnificent cathedral, and it is much frequented by tourists.
