Sonic drilling is a method of penetrating the soil that substantially reduces drill bit and drills string friction. Such an attribute is owing to soil liquefaction and loss of soil porosity (which is only temporary). This makes it possible for sonic drill rigs and associated tools to penetrate and get through a wide spectrum of challenging types of ground formations.
The sonic type of drilling, compared to other traditional drilling methods, has been around for some time now. However, this particular type of ground penetration technique has all these years remained in its “adaptation” phase.
As a result, drilling contractors are frequently called upon to “educate” their water well, mining, geotechnical, and environmental clients on the technology and how to successfully utilize it. They also help them become familiar with the array of benefits that it can provide them for their projects.
A variety of sonic frequencies are used in drilling to convey the resonant energy from the drill string down to the bit face, mostly during the drilling process. The drill string is spun at the same time, culminating in a uniform distribution of energy and bit face impact.
Sonic drilling rigs are faster than traditional overburden drilling, depending on the site.
Sonic technology uses high-frequency resonance to get rid of or reduce friction between encountered subsurface material getting in contact with the tooling/core barrel while advancement is taking place.
This aims to mobilize a more efficient downhole penetration motion as well as allow for optimum subsurface core recovery in different kinds of subsoil conditions.
As for the resonant energy, this is conveyed from the drill string down the bit to the bit face at shifting sound frequencies throughout the drilling process.
When you are extending the drill bit to allow for an even impact, simultaneous rotation of the drill string will make way for an even distribution of energy and impact at the bit face.
Sonic Drilling Rigs Reduce Waste by 80%
Sonic drilling, when coupled with an innovative casing advancement mechanism, practically removes slough, guaranteeing sample integrity even when drilling into sand, limestone, dolomite, and other materials we classify as “unconsolidated.”
Sonic Drilling Produces Accurate and Reliable In
Sonic drilling is highly reputed for delivering unparalleled accuracy and quality of core samples via whatever type of formation in a generally undisturbed manner. Environmental scientists, geologists, and drillers — they can all be certain they can identify exactly where a sample of ground material is extracted from with a meager variance of 1%.
Better Well Construction
The sonic drilling rig is known to create a fully cased borehole that allows for the construction of a water well that is not likely to cave in or collapse. The water well is placed inside the casing itself. Then it will be gently vibrated to extract it. The vibration will help to keep the sand pack from bridging, guaranteeing in the process that it is distributed evenly all across the screen.
Sonic drilling addresses an array of critical safety issues, from accidental slips, stumbles, and falls; muscle strains; and the most troubling of them all, the exposure to chemicals or machinery.
In the absence of auger flights, the drilling apparatus is exposed to less risk. Soil samples are retained inside the core barrel and pulsed into a sealed PVC sleeve. This mechanism will keep it from being exposed to a range of harmful contaminants. Reduced IDW generation decreases the need to handle or transport the material, laying the groundwork so you have a safer and cleaner workspace.
