Stenuick was the precursor of the method of drilling with casing by rotation: the SATURN system (see machine S1100DT Double Tête).
Originally, this system was designed to face the problems of drilling in grounds of overburden (gravels, clays, sands, alluvial material ...). It allows the drilling with the down the hole hammer while going down a casing simultaneously.
Two methods are available : the casing system by rotation called SATURN and the casing system by impulse of the hammer on the casing shoe of the casing called commonly ODEX or TUBEX.
Some examples of applications of the overburden drilling system :
- Water well drilling (consolidation of well heads, polluted groundwaters exclusion, ...)
- Geothermal drilling
- Civil engineerings (anchorages, injections, road crossing, ...)
- Mining exploration(pilot hole for core drilling, study of groundwaters, ...)
