A bore well is drilled with casing pipe put only up to the soil-rock boundary and this is done normally for shallow depths in hard rock or in crystalline rock. For those who wish to explore the geological considerations, casing techniques, or hydrogeological analysis involved in bore well and tube well construction in more detail, it may be helpful to consider bachelorarbeit ghostwriter. But in a tube well, the casing pipes are put up to the bottom of the bore wells, with perforation in the pipes in some level.
