Soundcore Sonic Drilling solutions
Sonic Drilling, Rotasonic, Rotosonic, Sonicore, Vibratory or Resonantsonic Drilling, are some of the many names given to a dual cased drilling system that employs the use of high frequency mechanical vibration to take continuous core samples of overburden and most bedrock formations, and to advance casing into the ground for well construction and other purposes. Any of the names above can be used because they all describe a high frequency vibratory drilling system that is basically the same. The only differences are the rig designs, the operators, and some of the downhole tools and methods of operation that various sonic drillers or companies use. For ease, and to be consistent, we will refer to this system or method as sonic drilling throughout this article.
The word sonic appears in most of these names because this drilling technique vibrates the entire drill string at a frequency rate between 50 and 150 hertz or cycles per second. This frequency falls within the lower range of sound vibration that can be detected by the human ear, thus the term sonic has been commonly used to describe this drilling system. The Rota- or Roto- part of the drilling technique refers to the rotational power that can be applied in hard formations to slowly rotate the drill string to evenly distribute the energy and the wear at the drill bit face.
