The sonic drilling technique was already used in the environmental industry decades ago to drill faster, safer, and cheaper.
Although this type of technology is not new, still, some drillers are not aware of its advantages for their projects. Until now, some drillers are still using the conventional method of drilling for several reasons.
For those who are still not familiar with this technique, it is an advanced method of drilling that uses high-frequency, resonant energy produced inside the sonic head to move a core barrel into subsurface formations.
This methodology is best for deep and shallow surfaces where high-quality core samples are required.
To prove that sonic drilling is the better drilling method for a particular project, check out the advantages of this technology.
Sonic Drilling Is Faster than Conventional Method
When it comes to speed, a sonic drill can penetrate four times faster than the conventional method. The high efficiency of this method is due to the utilization of high-frequency resonance to minimize the friction between the subsurface materials it comes across as the core barrel is being advanced.
Penetration and core recovery are very efficient in different high-density layers using this technique.
Lower Investigation Derived Waste (IDW)
Compared to auger or rotary drilling processes, sonic technology can reduce the investigation derived waste (IDW) up to 70-80%. This waste minimization was made possible by using an innovative casing advancement system that eliminates slough, which as a result, provides superior sample integrity even in various unconsolidated materials.
Delivers High-Quality Samples
Another top advantage of sonic technology is delivering superior and undisturbed core samples in any soil conditions or formation. Preserving the integrity of these samples is highly important for geologists and scientists in determining the origin of these samples.
Better Safety Features
Safety during the drilling operation is the top priority of every driller. Considering the dangerous working conditions on the site, mitigating the risks is crucial. With sonic drill rigs, these risks are effectively managed due to their better safety features compared to the conventional method. This method employs operating systems that will require lesser people on the site, thus, fewer risks involved.
Lower Noise Level
Sonic technology has a low noise level compared to hammering using prob rigs.
Better Resistance from Wear and Tear
Compared to hammering, sonic drills have better resistance with wear and tear, which means less maintenance.
Taking into consideration all these advantages that sonic technology has to offer, indeed, this method can be a better option for drillers who are looking for better and efficient processes.
Lastly, the main objective of this article is to help drillers by providing them with other alternatives to make their work more efficient, safe and achieve better results.
