It also provides samples of soil and rock, as well as samples for a variety of on-site experiments. This method is used in the drilling of non-vertebral holes for horizontal drainage or containment. Today, the use of rotary drilling machines is very common. These devices can be used on any type of ground. But the superiority of their use in soft areas is greater. The progress of these devices inside the hard rock is slower. In this way, the head of the steel drill that connects to the end of the steel pipe rotates through the well with the help of the engine. The drilling mud is injected into the well from inside the tube and returns from the pipe around the well.

Although most of the oil wells are drilled by rotational method, still in some oil-rich countries, especially the United States, still used a blast method, and it is estimated that nearly to percent of US oil wells are dug by impact. Duranti drilling was first used in Spateletop, near Texas, in , and due to its advantages in terms of impact, its scope soon expanded. As in the s, most of the excavations that were done to extract oil around the world were by this method.
