Geothermal & Waterwell Drilling
D&B-8W
The D&B-8W geothermal and water well drilling rig is engineered for exceptional performance in hard rock formations, aquifers, and mixed geological conditions, making it ideal for drilling depths of up to 150 meters.
The adjustable feed pressure and powerful Daedong D2300T 54HP diesel engine deliver consistent drilling performance. The full hydraulic system, featuring a variable-speed feed control and open-loop design, allows operators to adjust drilling parameters in real time, optimizing performance across different ground conditions. Engineered for compact transportability and maneuverability, the crawler-mounted design enhances stability, making it an ideal choice for small to medium-depth geothermal drilling projects.

Exceptional Water Hammer Benefits
With a hydraulic system optimized for high-torque rotary and DTH hammer drilling, the D&B 8W achieves up to 2× faster penetration through limestone, dolomite, and crystalline rock while reducing bit wear by 50%. The high-impact reciprocating action of the water hammer minimizes drilling resistance, enabling efficient rock penetration while lowering maintenance costs. Unlike mud-based drilling systems, which can contaminate aquifers, the water hammer technology operates with a clean water circulation system, ensuring environmental safety and reduced waste disposal costs. Additionally, its fuel-efficient Daedong D2300T diesel engine (54HP) with a water-cooled system lowers diesel consumption, cutting operational expenses while maximizing overall drilling productivity.

The D&B-16W is more than just a deep drilling rig—it is a strategic investment for drilling contractors and energy developers looking to scale geothermal and water well operations efficiently and cost-effectively. Designed for high-throughput drilling, this rig significantly reduces the logistical and operational challenges associated with deep borehole projects. Its crawler-mounted mobility allows for easier site access, even in challenging terrain, while its fast setup time ensures minimal downtime between projects.
The Hydraulic Open-Loop System optimizes fluid power distribution, enhancing precision drilling control, particularly in formations where variable pore pressures or fractured rock zones pose challenges. Additionally, the rig’s modular design allows for seamless adaptation to different drilling methods, ensuring compatibility with various casing diameters and borehole configurations. The dual rotary system option further enhances its capability for large-diameter drilling, making it ideal for projects requiring wide casing installations.
With long-term durability in mind, the D&B-16W is engineered with reinforced structural components to withstand continuous drilling in high-density rock formations, reducing fatigue-related breakdowns and minimizing maintenance requirements. Its fuel-efficient powertrain and hydraulic efficiency lower overall diesel consumption, making it an environmentally responsible choice for operators looking to meet regulatory emissions standards. Whether deployed for municipal district heating wells, deep aquifer extractions, or high-capacity water well drilling, the D&B-16W ensures reliable performance across diverse geological settings, reducing both per-meter drilling costs and total project timelines.
