If you listen to the words of sonic drill rig manufacturers, you will agree with them when they assert that the sonic drill technology has remained dynamic and is enjoying sustainable growth over the last 2 decades. Most especially when they show you some of the reasons why it is so.
Expert minds from this industry attribute this dynamic vibe in this space to two major elements. The first on the list is the development and increase in the number of highly skilled drillers. Most of these workers have the focus of their specialization in sonic drilling. Coming in second place here are the different technological milestones used in this industry.
For as long as the sonic drill operator is highly skilled, the odds of him getting high production rates are very high. At the same time also, he will know he can obtain quality samples from a wide range of subsurface conditions. There is so much power in sonic drill rigs, they can let you reach great depths into the ground while trying to get 100% sample core in your project site.
The sonic drill rigs are powerful and they are capable of reaching greater depths while trying to obtain 100% core samples in the project site.
The Best Time to Use Sonic Drill
Understanding the best time to apply the use of sonic drilling for various drilling projects is of paramount importance in delivering a profitable and desirable result or outcome for the customer.
Here are some good points why sonic drilling method is a standout among many other drilling technologies we have nowadays:
- Drilling jobs that necessitate you to gather and collect continuous core samples from the worksite which is pretty much the opposite of reverse circulation drilling. If you don’t know this yet, reverse circulation drilling collect chips.
- For those drilling jobs where you need to veer away from fluid or air during drilling. Sonic technology has eliminated the use of air and fluid in this kind of drilling technique. This explains the reason why it has become the method of choice for most geotechnical, environmental, and geo-constructions applications.
The odds that environmental projects are going to get significant cost savings by taking advantage of this drilling method is high.
- For various exploration and drilling projects where there is a good chance that you will encounter unconsolidated formations on the ground, this method of drilling into the earth is the method of choice. Why? It is because it allows you to handle just about anything, from boulders to pebbles while keeping the borehole integrity intact.
Drill Shoes and Bits
There is a range of sonic tooling best suited for specific ground conditions and hardness. Ground hardness would start from an unconsolidated ground climbing the scale up to 10. This has something to do with the mineral hardness on the Mohs scale.
When you happen to stand on, say, unconsolidated ground, take note of the sizes of the rock and with respect to this aspect you should make necessary adjustments or tweaks to the core barrel settings. For example, if you reckon that rock sizes would be ranging from 3-4 inches in diameter, the driller may choose a core barrel with a diameter of at least 6 inches.
By securing an adequate core barrel size on hand, you are ascertaining that your drilling samples would get extracted through your core barrel, which promotes greater convenience and ease of collection.
Core Barrel Telescoping
Friction is the first factor here that will certainly go against you. The use of a technique known as telescoping will help you mitigate the level of friction that is likely to be produced in your drilling work. It allows his boring effort to go deeper into the ground than he can anticipate. For this, you can size your core barrels according to the casing size.
