If you want to drill a new well on your land, then you need to choose the right drilling method. In many cases, rotary drilling is a good all-around solution. How does this type of drilling work? Why should you consider using it?
What Is Rotary Drilling?
Rotary drilling uses a diamond-tipped drill bit to cut down into the ground. This bit is attached to a hydraulic drilling pipe. As the pipe pushes down into the ground, the bit turns and cuts. As it moves down, it pushes the material it displaces up to ground surface level.
Depending on the depth of the well and its soil type, your contractor might add stabilization to the drill hole to stop it from collapsing. For example, they might insert a casing to keep the hole open during the drilling work. Here, the drilling equipment inserts the casing to hold the hole open as it advances.
While all rotary drilling techniques work in much the same way, you can use different methods for different jobs. For example, mud rotary drilling works well on loose soils that might backfill boreholes as they are drilled. Here, your contractor uses a special fluid or water during the drilling process to create mud around the hole to keep the surrounding earth in place.
What Are the Benefits of Rotary Drilling?
Rotary drilling is fast and efficient. If you want to drill a simple well in a short amount of time, then this process will work well. This type of drilling also works well if you have difficult ground conditions. A regular air rotary drill can cut through soft, hard, and rocky ground without making too much mess or without using drilling fluids that might contaminate the soil. It can drill down lower and create wider boreholes than other techniques.
Plus, this drilling technique can adapt to different ground conditions and well-boring needs in multiple ways. For example, you can manage soft or sandy earth that might collapse by using a mud rotary system. The drill creates a holding mud liner as it drills.
Or, if you need to drill down deeper or to make a wider bore, then you can use a reverse-circulation system. Here, the drill has two tubes, one of which carries cut waste straight to the surface.
