Abstract

Process for creating an artificial permeable layer in subsurface for exploitation of geothermal energy, said process comprises the following steps: A) digging a well (2) by excavation means (1), and at the same time coating said well by a jacket tube (4), said jacket tube (4) comprising a plurality of elements that can be coupled in a removable way; B) removing excavation means (1); C) removing at least one element of said jacket tube (4) of the well (2) leaving a space between the lower end of said jacket tube (4) and the bottom of the well (2); D) inserting in said jacket tube (4) a bullet (P) containing at least one explosive charge (23); E) triggering said at least one explosive charge (23) of said bullet (P); F) firing said at least one explosive charge (23) of said one bullet (P), in the space between the lower end of said jacket tube (4) and the bottom of the well (2), with consequent creation of a crushed area (11) in the subsurface forming said artificial permeable layer. The invention further concerns a bullet for realizing said process.
