Abstract (en)
[origin: US5322128A] A method of forming well regions for improving well efficiency is performed by forming a first bore hole to a ground region having a relatively good liquid guiding properties, forming at least one second bore hole near the first bore hole to the same ground region, loosening and at least partially washing out components of a ground material surrounding the bore holes in the ground region by at least one of pumping in or aspirating liquid into or out at least one of the bore holes, and introducing into at least one of the bore holes after removing a bore tube, a well tube so that permeable well tube regions are located at the height of the washed ground region surrounding the bore holes.
