The standard method involves percussion drilling in which a drill is alternatively raised and dropped in the descending borehole. It is suited to the drilling of wells in any material from soft clay to the hardest rock.
[pdf] An Integrated DTH (Down-the-Hole) Drill Rig is an advanced drilling system designed for efficient and precise drilling in hard rock formations. It combines the power of a DTH hammer with a fully integrated rig system, offering high penetration rates, accuracy, and operational flexibility.
[pdf] Water bore drilling relies heavily on water well rigs as they are the main equipment used for this purpose. These specialized rigs are tailored to reach deep into the earth’s surface, enabling access to underground water sources.
