Over the last two decades, sonic drilling has gained widespread acceptance and popularity. It enjoyed industry-wide recognition. Two key contributing factors to this growth have something to do with technological advancements and the emergence of highly skilled drillers specializing in the use of sonic drilling rigs.

A skilled operator of a sonic drilling system may achieve high production rates and produce the best quality samples from a variety of subsurface conditions. Together with trained drillers, the sonic rigs make it possible to reach greater depths while getting into near-complete site core samples.

Recognize When to Utilise Sonic Drilling Rigs

Knowing how to discern the best time to use sonic rigs instead of traditional drilling is critical to providing cost-effective outcomes for the client.

We have the following 3 reasons why you should utilize sonic drilling technology:

  1. Projects that necessitate the collection of a continuous in situ sample — this is the complete opposite of reverse circulation (RC) drilling, which collects chips.
  2. When drilling conditions require the exclusion of fluid and air, sonic drilling rigs do not need fluid or air, hence qualifying them as an excellent technique for geo-construction, environmental and geotechnical applications. Sonic types of drilling can lead to significant cost savings for environmental projects. These forms of initiatives can be rather costly and time-consuming to complete to dispose of IDW (investigation-derived waste or otherwise known as drill cuttings) properly. Drilling dry lowers liquid waste compared to rotary procedures or drill mud/water.
  3. Sonic drilling is an excellent solution for undertakings with unconsolidated subsurface formations because it can effectively drill through pebbles to boulders whilst preserving borehole integrity through a continuous casing operation.

Make Use of the Right Drill

drilling rigsThere are many kinds of sonic tooling accessible nowadays that can help meet a variety of ground hardness and condition levels. The hardness of the ground is different from the unconsolidated, which is around 10 on the mineral hardness Moh’s scale.

Pay attention to the size of the rocks on unconsolidated terrain and modify the core barrel appropriately. The driller should use a core barrel that is at least 6 inches in diameter, regardless of the rock size. Ensuring a suitable core barrel size helps ensure the samples can easily be collected as they pass through the core barrel.

Telescoping the Core Barrel

Friction is your adversary when you are drilling through the earth, and any professional in this business would agree with that. Telescoping the digging minimizes friction and permits the contractor to bore further and deeper. Core barrels should come in the casing size. 

Don’t Just Keep an Eye on the Gauges

The greatest sonic drillers do not rely solely on gauges to determine when to back off or press forward. When skilled drillers operate the sonic drill string, they may rely on their senses to determine how the drill string is advancing; they can touch and feel it. They can also hear how the drill string is making progress, and from there make appropriate adjustments and decisions.

Additionally, experienced drillers rely on their familiarity with the drill site and ground structure. And the greatest drillers are adept at adapting their tactics as the hole deepens and comes into contact with new ground formations.

Why the Honchos of Drill Rig Companies Consider Sonic Drilling is a Sound Solution for Frustrating Ground Formations?

oil rigTop drill rig companies in the aggregate industry make use of sonic technology in assessing the probable quality of both sand and gravel deposits. It has been found that drilling the aggregate with a sonic device offers significant advantages which companies involved in the drilling industry must take advantage of. 

By applying resonant energy, sonic drilling can advance the core barrel into any kind of subsurface structure. Sonic frequencies are involved while drilling work is in progress as the vibrational energy in the drill string is funneled down the bit to the bit face.

The string rotates simultaneously and concentrates the energy and impact on the bit, distributing the energy and impact more evenly over the string’s surface. The outer casing is then drilled to the same depth as the main barrel. This does not necessitate the use of any fluid or water. 

Distinct Benefits of Sonic Drilling

Superior Quality of Information

This approach produces a fairly undisturbed ground sample because the sonic cutting action shears the soil cleanly without using any kind of fluid that will dilute the sample. Core recovery is almost 100% and stays deep in the subsurface, which allows better knowledge for decision-making.

Speed

Vibration and slow rotation provide for an increased advance rate, which is significantly helpful when drilling work is in progress through unconsolidated formations while yielding penetration speeds up to 3 times faster compared to those that can be experienced while drilling overburden.

Reduction of Drilling Waste

Drill breakage and waste are decreased by as much as 80% when the drilling is done efficiently and without the use of water or any liquid. When miners have this power, they are better able to determine the best course of action for their ventures and to manage their capital.

Reduced total time and costs by virtue of sonic drilling help you to avoid the risk of a project fiasco or having a prolonged project which is often brought about by unknown or unforeseeable difficult subsurface conditions. Besides, it comes with an adverse environmental impact, too. 

oil industry

Sonic drilling is useful for many mining applications because of these advantages. Drill rig companies can sample unconsolidated ore piles and use tabulation techniques to estimate reserves out of current legacy stockpiles. 

These stockpiles are typically depleted of ores. They may also examine leaching efficacy, identifying dry conditions and enhancing the leaching process, and increase the yield of the desired minerals.

A complete rig setup usually has these characteristics that make them highly suitable for shallow drilling into an overburden or pre-collaring before drilling with a traditional drill.

Sonic drilling is ideal for geotechnical research for building and mine construction projects. Sonic rigs that are smaller and have lower ground pressure can be taken advantage of in environmentally sensitive areas, like when you need to drill without creating any damaging impact on the pavement. It is also very ideal to use when you don’t want to disrupt existing grass beds, or even enter murky wetlands.

When it comes to digging for water wells, we can say that they are pretty much a straightforward process. The traditional approach will have us dig a hole right into the ground until you reach a certain depth where you can reach the water table beneath the ground. After reaching the water table underground, you can then make use of a pump and a couple of drilling pipes to draw water up to the surface above, and voila — you have a water well. 

Digging for a geothermal well is analogous to digging for a water well. This brings us to this question here, where does the cloud of confusion in geothermal drilling stem from? We may need to dig in on this to find out more.  

Defining What Geothermal is All About

The geothermal HVAC system is the system of heating and cooling your home’s indoor space naturally. It utilizes the natural and consistent temperature of the earth which comes from under the ground to heat your home during the colder months of the year.

Conversely, you can take advantage of a geothermal HVAC system in the muggy months of summer to “move “the heat from your indoors into the drill. There is a good chance you can achieve this also with the various geothermal drilling rigs for sale in Australia. The temperature of the earth and its crust is around 55 degrees, and this is constant throughout the 365 days in a year. 

This goes to show that even if you live in a geographic region that is heavily blanketed by a thick pile of snow most of the time, a few feet below the earth’s temperature remains at 55 degrees. The main job of a geothermal heating system is to harness this amount of heat and move that to your home.  

Why Is the Geothermal Heating System Beneficial? 

We can name a few good points why geothermal drilling rigs for sale in Australia that are intended for use in heating and cooling systems are taking the lead from the conventional HVAC alternatives.

First off, this is eco-friendly – this is because you are harnessing the natural energy of the earth but without putting it in harm’s way or compromising it. 

Geothermal HVAC systems are also affordable and easy to budget. Most of the time, they cost cheaper when compared to the traditional use of natural gas or even heating oil to operate. Besides, these equipment are also quiet to operate, reliable, efficient, and most importantly, low on maintenance.  

How Do They Work? 

“Moving” heat from your home would necessitate the use of a few pieces of equipment known as “loop”. With respect to a geothermal heating system, two types of loops are commonly used — the open and the closed-loop.

The open-loop system would be relying on 2 wells, one of which would be a supplying well and the other would be a return well. Alongside also, water is being circulated by virtue of a piping system installed between the two. 

In a closed-loop system, the water solution will be inside the pipes all the time (think of a lava lamp). This will be circulated throughout a home’s ventilation.  

Where To Dig for Your Geothermal Well? 

This is a resounding question from many homemakers. It only goes to show that they are most interested in what it has to offer them as far as geothermal HVAC systems are concerned.

If you will be looking for drilling rigs for sale in Australia, a qualified dealer will help you and assist you in identifying the best spot in your backyard to dig for a geothermal well. You can usually rely on a competent team for this, and once everything is all up you will get to appreciate why harnessing geothermal energy for your home heating and cooling needs is the most beneficial and practical option there is.
