Even if we don’t qualify sonic drilling as new, there is one thing about this technology that we are very much certain about — all these years from the time it was introduced to the industry it has remained to its adoption phase.
What does this imply, you may ask?
This means to say that a drilling contractor must exert effort in educating their water well, mining, geotechnical and environmental clients about it. He needs to make them aware of the reasons why this technology will work to the advantage of their existing projects.
Sonic drilling is faster than conventional overburden drilling methods depending on site-specific considerations.
Sonic technology makes use of high-frequency resonance. This helps eradicate or minimize the friction that will exist between the encountered subsurface material and the core barrel or tooling being advanced. This allows for maximum core recovery and efficient penetration in a manifold of subsurface conditions.
While the drilling process is ongoing, the resonant energy will be transmitted from the drill string down to the drill string at different sonic frequencies. By rotating the drill string, the energy and impact are evenly distributed at the bit face.
Sonic drilling minimizes the creation of waste by 80%
When you employ sonic drilling for your drill project, it will eradicate the creation of slough. It allows for improved sample integrity through dolomite, sand, limestone and a host of other unconsolidated material.
Sonic drilling delivers superior information
Sonic drilling is one of those drill technologies that can provide you with a relatively undisturbed sample of a core with unparalleled accuracy and quality, regardless of soil formation encountered. Geologists, drillers and even environmental scientists are all given a good chance to know the exact origin of the sample.
Sonic drills come with profound versatility.
Sonic technology is one notch more advanced than other drilling techniques in such a way that its outstanding penetration capability eradicates redrilling exploration borings. This is one of the notorieties of traditional exploration techniques.
In addition to this, the footage drilled, rate of production, and sampled per shift are way higher with the use of the sonic technique. The more challenging the formation is, the more immense the differential is, favoring the sonic method.
While the depth of boring increases, sonic drilling performs better when it comes to maintaining production levels whereas cable tool drills and stem augers see the production drilling minimized as the depths reach 100 feet below and beyond.
It does not only have a depth advantage, more than just having a superior quality sample, but the sonic sample is also relatively heftier in volume. It is only under 95mm in its diameter. This paves the way for grading of the samples with more than enough sample volume that can be used for simulations and favorably pull down the number of required boring.
Sonic drilling also employs dual tube system which impacts the production drilling in unstable alluvial formations. There is nothing unusual here because it is common in many gravel and sand searches. While the boring is advanced, the borehole integrity is maintained by encasing it. The associated caving problems and the loss of production are eradicated, the footage drilled at every shift is maximized.
