Program description:
Drilling water wells and geothermal boreholes can be a complex task, but using dual rotary drilling can make the process much easier. Dual rotary drilling is well-suited to both geothermal, water well and exploration projects, where accuracy (straightness of the borehole), speed, and flexibility of the drill are key. With dual rotary drilling, the top and lower drives can be adjusted and controlled easily, allowing for a variety of options when drilling through different terrain types. The drills have high torque capabilities and the ability to reach depths of over 500 feet, ensuring that all kinds of wells and boreholes can be constructed with ease. This makes it perfect for any project that needs precision drilling at depth or where clean dry gravel or boulders are expected. Our experience using dual rotary drilling in water wells and geothermal boreholes has shown impressive results in terms of efficiency and accuracy. Additionally, its versatility allows for a variety of drilling methods, such as mud rotary, air-rotary, and down-the-hole hammer. Overall, dual rotary drilling offers the perfect solution when it comes to constructing water wells and geothermal boreholes. Its adjustable speed and torque capabilities make it incredibly efficient while still providing straighter boreholes, and the ability to see the formations quicker and easier. With its versatility in different drilling techniques and deep reach capabilities, dual rotary drilling is the perfect choice for any kind of project.
