What I did: I made the detailed design and project management of the installation of an high tension electrical infrastructure, performed by using dry directional drilling. All the installations were carried out in karstic rock (sandstone and limestone) with voids and caverns. Pilot bores were drilled by using a Down-The-Hole 4″ directional air powered hammer, equipped with a wireline Digitrack guidance system. Each borehole was reamed up to 550 mm (22 in). The overall installation length was 1.000 m (3,300 ft). Max crossing length: 220 m.

What I did: I collaborated in the development and application of the Dry Directional Drilling technology, being member of the team that developed this technology.
About Dry Directional Drilling technology: DDD is based on the use of compressed air at low pressure (175/360 psi – 12/25 bar) instead of traditional bentonite mud. Down the hole percussive air powered tools have a blow frequency that ranges from 900 to 1.500 blow per minute, which means that they are able to drill, with successful results, any kind of soil and any kind of hard rock banks, even when the rock has a resistance to compression of more than 29,000 psi (200 MPa). The rotating and percussive action exerted by the down-the-hole tool is extremely efficient even in presence of very hard rocks. Moreover, it turns out to be very useful in presence of soft soils, since the percussive action generates a pre-consolidation of the soil, so that it facilitates the drilling and steering stage.

Year: 1994-2007
What I did: I designed the product (drill pipes) in a wide range of diameters, connection types and lengths, setting-up all the mechanical calculation methods; then I studied the manufacturing process (friction welding, thermo-chemical treatments, post welding heat treatments) and all the control procedures; and finally I designed and supervised the construction of the manufacturing plant. Six year of continuous research, enthusiasm, errors and success, achieving a deep knowledge about the directional drilling process, and steel and metallurgy. We set a new standard reference in the industry of drill pipes for shallow horizontal directional drilling. Some patents and some innovative ideas complete the achievements reached thanks to this collaboration.
