Why Sonic Rig Drilling Works?

If you have a relevant background in the oil exploration and drilling industry, you’d understand why you must be familiar with the many different kinds of drilling techniques. Like for instance, you need to know what makes sonic rig drilling work that major industry players prefer to use it over other available drilling methods. 

Sonic drilling is a qualified technique to penetrate the soil. This ground penetration technique is sought out by companies when they need to drill into the ground for various purposes due to its friction-reducing quality that occurs both on the drill string and the drill bit due to inertia effects, liquefaction, as well as the temporary soil porosity reduction. The combination of all these factors makes it possible to have seamless penetration for many different kinds of soil quality.

Besides, this technique also makes the penetration rate in the vast majority of bedrock types faster.  

Generating Sonic Vibration with the Drill Head

Drill heads normally house the oscillator, which is highly responsible for the generation of resonant, high-frequency energy. Usually, this is directed into the drill string. While drilling is in progress, the rotational movement is combined with resonant energy. By this measure, there is an even distribution of the energy and this will leave an impact on the drill string and drill bit of tooling. 

Drill operators have full control over the intensity of sonic vibration that the drill head will generate. This will significantly help in matching up the required force needed in penetrating bedrock and soil formations.  

Sonic Rig Mechanics

If you will try to engage a powerful drill head, you’re taking the entire drill string to a vibration frequency reaching as high as 150 Hz. This will induce the drill string and bit to lose hold of its structure. And with this, it will also reduce soil friction and drill cuttings so they become extremely loose to the point of assuming a liquified form. Thus, it can be flushed or removed easily from the borehole.  

The drill bit vibrations will render the soil to significantly lose its porosity and density, and eventually its structure. By this measure, the soil and cuttings will get moved in the sample barrel as well as up the drill string, helping your tooling to freely advance on its own.  

The inertia effects and liquefaction allows for the collection of continuous and long samples. And because of the presence of the high-frequency vertical movement, the odds are high that the drill string will be staying extremely straight yet with very little possibility of deflection.  

Less power, fewer problems

Due to the reduced amount of friction that will likely occur on the drill string length, sonic rig drilling will require lesser amounts of power to achieve the exact or same drilling power as what can be witnessed from other traditional drilling methods. This is one attribute that is solely unique to sonic drilling and will help in keeping torsional forces to begin appearing on the drill string. 

Another major benefit that can be enjoyed from applying sonic high frequency is how easy and seamless is the process of retrieving the drill string, even when working on quick expanding clays, boulders, and other similar but difficult or challenging conditions. All drilling rods, toolings, and casings can be pulled easier and way faster.  

Sonic Drilling Means Clean Drilling 

There are a handful of situations where you want to shy away from using air, drilling mud, or even water while drilling work is in progress. In a sonic type of drilling, they are not necessary. Hence, this is the reason why it is the most preferred geo-construction, environmental and geotechnical applications. 

Environmental projects will also enjoy significant savings on their costs if they will take advantage of the sonic type of drilling method. These kinds of drilling projects necessitate a good amount of time and money so that project managers will be able to properly dispose of their investigation derived drilling waste.  

Also, in every mining project, there is a leach pad. If you add air or water it is going to be a disturbance and may influence the soil’s mechanical properties. Under extreme cases, doing so may bring about the possibility of erosion which can pave the way for failure of drilling operations such as a partial landslide.

How to Choose the Drill Rigs Australian Brand?

There are plenty of reasons why we would be needing a drilling rig. We can use it in an array of applications, and if we have a project that necessitates us to drill first then we can turn to it for some help.

Like for instance, if we have a project that will help us gain access to a natural resource such as geothermal, oil, or water, a high quality, reliable, and dependable drilling rig would be of prime importance here. We can also make use of a drilling rig in making structural foundations as well as in creating blasting holes in a mining site. Or maybe we can use it to dig deep into the earth to obtain ground samples. 

Aside from identifying the purpose you have to acquire a drilling rig for sale, you also need to know the terrain you will most likely use it on. With respect to the ground or terrain, you may choose from the different kinds of drilling rigs the industry has to offer: percussion drilling rigs, rotary drilling rigs, top hammer drilling rigs, down-the-hole drilling rigs,  

You can never go wrong with your choice and decision for acquiring a particular type of drill rig if you will determine first whether you will have the drilling rig for your core business or if you will have it for occasional operations or special projects only. Prime considerations here to determine which one would be more suitable to your requirements would be taking advantage of the recent drilling technology innovations or picking instead a tried and tested, reliable drilling machine.

Reliability, safety, and ease of use. All these three are crucial elements and you need to take them into account. According to the leading manufacturers of drill rigs Australia brands, when their product offerings are used in line with their recommendations, their level of safety would be increased. 

Another important thing that you should not leave out is defining the type of your required mobility. There in the market, we can find a trailer-mounted type or the autonomous crawler drill rigs. As for the truck-mounted types, you need to have them powered by a generator. It will work okay also if the truck that will carry them will power them up.  

After you have settled on the type of drilling rig you need to have, you’d be able to figure out or calculate the required size with respect to the depth of the borehole and the diameter.  

Many different projects would require you to carry out drilling work first. Under the following scenarios, you will need to have access to high-quality drill rigs Australian brands execute your upcoming project. 

  • Drilling for wells. This type of well could either be for oil or groundwater. 
  • Pile drilling. If your project involves building a structure on what is determined as unstable ground, pile drilling will help provide the required support. They are usually 70 meters deep and around 2,000 millimeters in diameter. 
  • Geothermal drilling. It helps in obtaining access to the earth’s heat for extraction and processing a renewable form of energy. 
  • Micropile drilling. Used most for the reinforcement of existing structures. This type of drilling is usually 30 meters deep and 150 to 200 mm in diameter. 
  • Blast hole drilling. These types of drilling holes are used in quarrying sites.  
  • Continuous flight augering. It is a type of drilling work that involves the maintenance of the borehole walls using the drill cuttings as driven by the auger.  

Normally, drilling activity is carried out vertically, but there are also instances that it would be executed horizontally or directionally. Typical examples of which are drilling for the anchor placement.
