Which drilling method is the most commonly used for drilling wells?

The direct rotary drilling method is recognized as the most commonly used technique for drilling wells due to its efficiency and effectiveness in a variety of geological conditions. This method involves rotating a drill bit while simultaneously pumping drilling fluid, which serves to cool the bit, lift cuttings to the surface, and stabilize the borehole. The continuous rotation makes it suitable for penetrating harder rock formations and allows for faster drilling rates compared to other methods.

Furthermore, direct rotary drilling provides greater control over the drilling process and can be adapted for both shallow and deep well drilling. It is particularly advantageous in areas where precise well placement is critical, and it allows for the use of a wide range of drill bits tailored to different subsurface conditions. This versatility and efficiency contribute to its prevalence in groundwater well construction and other drilling operations, making it the preferred choice among professionals in the industry.
