Sonic Drilling Method: How Does It Work?

Drilling with high-frequency, resonant energy created inside the sonic head is an advanced kind of drilling. As the sonic drilling string moves down the hole, resonant energy is transmitted at various sonic frequencies to the drill bit face.

How It Works

The sonic drilling equipment consists of three main parts.

  • Drill Head
  • Resonator (drill pipe or drill rod)
  • Soil type

As a result, the method’s three interdependent components must operate together harmoniously to be effective.

Sonic Drill Head

For this approach to be effective, tremendous vibrational wave energy must be efficiently transferred from the drill pipe’s upper section to the drill bit’s lower section, with very little power being lost in the process.

Counter-rotating rollers or eccentrics are often used to create linear forces. Although it does not cut, the bottom bit crushes the rock into dust or bludgeons mud and clay to the side.

Resonator

oil rigSonic drilling heads are designed to apply as much power as possible to the top of the drill pipe while transferring as much energy as possible to the bottom of the drill pipe, where it can be most effective in piercing a formation’s formation.

The frequency of energy input must fluctuate as drilling proceeds and new sections of pipe are added to maintain the wavelength condition. It takes less input energy to bring the steel drill pipe into resonance as it becomes longer.

To be sure, higher frequency operation of the sonic head allows for increased force production as drilling depth increases, allowing for sustained penetration at longer depths.

Drilling with Sonics

Soil is fluidized by the resonating drill steel when the sonic drilling head and the drill steel pipe are brought into resonance. This reduces the frictional forces that bind and constrict the pipe.

If you’re drilling in sandy or gravelly formations, the drill bit will readily disrupt the elastic connections between the particles. The sand grains will then rearrange themselves and migrate to the outside of the bit face.

Porous and saturated formations are more easily able to absorb soil particles that have been dislodged from the bit. Sonic drilling in clay-type soils is more difficult. Clays are less movable than sands and gravels because of their cohesive nature.

Sonically fracturing rock formations with tungsten carbide inserts requires special bit designs with inserts. A flushing medium, like air or water, is commonly required when drilling solidified formations to wash away cut material and keep the bit exposed to raw material.

Why Should You Consider Sonic Drilling?

Drilling applications requiring undisturbed core sampling across virtually any geological formation can benefit from sonic drilling. There are numerous advantages to using this strong technology as opposed to other sorts of drilling procedures. Low-impact technology makes crew tool handling safer by reducing the number of tools used.

 

How Do Water Well Drilling Rigs Work, According to Drill Rig Companies?

According to the country’s top drill rig companies, the normal tendency of many people nowadays is not to think so much about the working technology behind providing pure and safe drinking water. Not even the amount of work that needed to get done or the amount of effort that needed to be put in would be noticed. 

While there is a good possibility that the vast majority of Australian homes nowadays obtain their water from their own private well, there is a good chance that they probably didn’t have to pay a contractor for that. Or that they might not be even around yet when the well was drilled. 

But you have to admit, it is pretty impressive to watch a drilling rig in full action.  

Below, we will give you an idea of how it works. 

Drilling Rigs: How Do They Work? 

A water well drilling rig is a large piece of machinery that can only be transported by vehicle to the site where the well will be drilled and set up. These pieces of equipment can be qualified either as a rotary driller (they use a rotating motion to be able to dig into the earth) or they could be pounders ( they make use of a heavyweight to punch a hole using a technique known as “cable drilling.”

A rotary drill rig may employ a variety of bits to work. Long cable bits, as well as interlocking steel bits, are the most common types. Every single one of them rotates in a clockwise direction to be able to bore through the ground and thus loosen up the soil a bit. 

When the bit takes on its twisting action, the rock that is worked on is efficiently brought up to the surface. The drilling bits will remain cold enough by having mud or even water to cool the turning bit.

The objective of digging a water well is to reach the deep underground aquifer. However, this is not all there is. Drill rig companies can carry on digging below the water table. By taking things this way, they can make sure there is an adequate supply of water for the well and a long life for it.  

The length of bedrock wells typically ranges between 100 and 500 feet long. Although, there are instances that they could go deeper than that. 

Installing Well Casings

Casings are elongated pipes, usually made from steel or plastic material. They are used to line a new well to stop and keep it from collapsing while drilling work is in progress. In its absence, there runs the risk of contaminating the water below.

The annulus is a 2-inch gap between the casing and the good wall. For the remaining 20-feet before reaching the surface, this region will be filled with gravel and then get coated with cement. It will serve as a protection and will help in keeping pollutants and other unwanted materials/substances from reaching the surface of the well which may well contaminate the water supply. 

These casings also protect the well from freezing during the extremely cold winter months. It is the time of the year in the country when temperatures could go below freezing point. 

Although there are a handful of well-drilling companies that would mount the casing while their drilling work is in progress, others will do so only right after their drilling work is complete. 

Keeping the Water Supply Free of Contaminants

Filters are imperative when it comes to keeping debris and other surface contaminants from reaching the water source, which is naturally located at the bottom of the well. 

They are also responsible for ensuring that larger particles are not drawn near the water pump. A screen can be mounted at the bottom of the good casing for this purpose once the drilling work is completed and done.

At the bottom of the well, gravel, which is a natural filtration medium, can be taken advantage of for the same purpose, too.

Experience and Technology

Digging deep into the earth with shovels and buckets is a typical scene you will see when people of long ago would be digging for a water well. 

But nowadays drill rig companies can use a wide array of techniques and methods if they want to see to it that their client-homeowners will have a reliable supply of water for years to come. 

How to Find Second Hand Drill Rigs for Sale During COVID-19?

oil rigIf you have been mulling on whether you will buy a drilling rig or not, do you find it confusing if you should acquire a brand new system or if you should settle for second-hand or refurbished units instead? 

It is a tough call decision, yes.

Therefore you need to know exactly under what scenarios it would be advisable to have a brand new drilling system and when it is practical to have refurbished drilling equipment instead. 

There are several scenarios where the purchase of a second hand drill equipment and  system is best and more practical. Let us cite an example here for better understanding. 

We know that deep inside the earth an unimaginable amount of heat is trapped inside it. This amount of heat can be utilized for industrial purposes. One of its practical applications is to address the heating requirements of buildings. To harness geothermal heat for such purpose, a drill site should be installed within the vicinity. 

However, if the temperature is reaching the 35 degrees centigrade range or if it is even higher, it can be utilized instead for power generation or electricity production. Under these scenarios, it would be viable and more practical to settle for geothermal drill rigs for sale.  

Much like everything else, we can also utilize the power of the Internet on our quest to find a refurbished drilling rig to buy.  Bing, Google, and Yahoo are among the popular search engines that can help you on scouring the Web for used geothermal drilling rigs that are marked for sale. 

The vast majority of business organizations that are offering their drill rigs have a dedicated online presence these days. This allows you to reach out to them to inquire about their drill rigs for sale, and determine if it is a good buy for your company or whatnot. 

Most of the time, these drill rig systems can be mounted on, say, caterpillar trucks for greater mobility. With such configurations, you know that it would work to your advantage because it will allow you to move your drill rigs anywhere or around your target project drill sites.   

While deeper level drilling signifies greater expense, geothermal drilling efforts would often seek out those regions where possible earth structural anomalies would be existing and inducing higher temperature magma to come closer to the surface of the earth. 

Conducting drilling work on such sites would then be much cheaper on costs because it increases your chances of obtaining higher temperatures even with just a few short boreholes. During this time of the great COVID-19 pandemic, this will count a lot. 

In applications, where the borehole is situated at a distance from the application site, you’d easily drill for geothermal energy at such locations. The secondhand or refurbished drilling rigs for sale would be delivered directly to your project site by these selling companies.  

Since these pieces of equipment are considerably expensive, placing an outright purchase on them usually would not make sense in many situations. One practical work around here when you don’t have an available budget allotment for such a major equipment acquisition is to turn to finance options. They are usually  offered by reputable banking institutions and would be a practical alternative. 

Since the purpose of community quarantine is to put a limit to our mobility due to the coronavirus scare, the second best thing to do here on our quest to find the right kind of drill rigs for sale to buy to perform an online search.
