Benefits and Applications of Sonic Drilling

Benefits and Applications of Sonic Drilling

Sonic drilling works by using resonance energy. Its drill head sends high frequency vibration to the drill string or pipe up to the drill bit.  The drill rig operator can control the frequency of the vibration, depending on the type of rock or ground being drilled. The resonance frequency is usually between 50htz and 150htz. This resonance causes the rock or ground to become fluid-like at the surface of the drill.  The same as when you cut a hot knife through butter that is cold, sonic drilling significantly decreases friction. This allows drilling to be five times faster than other traditional drilling methods. This technique of reducing friction eliminates the need for using mud or lubricants while drilling. Sonic drilling only needs compressed air or water for flushing the cuttings. Sonic drill rigs can drill for up to 100 meters or 300 feet deep.

Sonic Drilling Benefits

Sonic drilling is more eco-friendly compared to other conventional drilling techniques. Unlike other drilling methods that use mud or lubricants, sonic drilling only takes compressed air or water when flushing the cuttings to the surface. This technique reduces possible contamination especially in sensitive environments. Overall, sonic rig drilling produces less waste. This drilling method is also more efficient because of its reduced friction, speeding up the drilling process. Moreover, with sonic drilling, you’ll have minimal disturbance or impact to the environment, which also means cleaning up the site is much faster and easier.

Sonic drill rigs are typically smaller machineries that use less horsepower. Less power needed means lower fuel cost. Its efficiency and lesser on-site waste means lower operational and labour costs as well. What’s also great about sonic drilling is that the drill rig operator can easily adjust and control the vibrational frequency to suit the type of ground or rock.

Sonic Drilling Applications

Sonics drilling is ideal to use in environmentally sensitive environments because it operates with reduced disturbance and contamination. Because drilling process is faster, the time spent in these sensitive areas is reduced. Sonic drilling is a great option for drilling places with difficult terrain because of its ability to change and adjust vibration frequencies, matching to the type of soil or rock. Conventional drills would be stuck in these types of environments, but not sonic drilling.

Sonic drilling is also the best choice for geothermal installations, as not only it can drill, but it can also case, and install loop and grout. Sonic drilling can do all of this in one operation for geothermal heating. Another application of sonic drilling is for environmental investigations. It can drill through landfill debris and able to take water or core samples no matter the depth. Sonic drilling is used in organic, heavy metal, and other types of contamination investigation. Moreover, this type of drilling method is applied in mineral exploration. If you are into geotech drilling and exploration, sonic drilling is the best option. It can take continuous core samples that are of high quality. The holes it drills are much straighter than traditional drilling.
