Rotary vs DTH Drilling
Choosing the right drilling method makes all the difference in efficiency, speed, and performance.
At ASquare - Tailored Drilling Needs, we design rigs capable of handling different geological conditions and we also help you choose the right drilling method based on your ground conditions.
--> Rotary Drilling
Best suited for soft formations like soil, clay, and sandstone.
Uses circulating drilling mud to remove cuttings and stabilize the borehole.
Common applications:
• Unconsolidated sediments
• Large-diameter bored piles
• Shallow water wells
--> DTH (Down-The-Hole) Drilling
Designed for hard rock formations such as granite and fractured rock.
A pneumatic hammer delivers powerful impact energy directly to the drill bit.
Common applications:
• Foundation rock sockets
• Hard-rock drilling
• Geothermal wells in hard formations
