Choosing the Perfect Drilling Rig to Hire

by | Dec 20, 2021

Choosing the ideal drilling rig to hire is paramount in any geotechnical drilling scenario. Depending on the job, it might be a no-brainer, but in many cases the choice will hinge on a variety of factors. Remember, your chosen geotechnical company should ideally have the right rig for the job – whether it’s a rental or a part of their fleet – but just as importantly, they must be entirely trustworthy. Investing in the perfect rig is pointless if it breaks down on-site.

The dedicated team at Borehole Solutions have delved into the various factors to consider when hiring a drilling rig for various situations. Keep reading to find out more!

What’s the scale of the project?

As with anything in life, geotechnical drilling requires the appropriately sized equipment for the specific job. Just as you wouldn’t approach an Airfix kit with a mallet; you wouldn’t utilise a sonic rig for a restricted access project in the centre of a city. Similarly, it would be a bizarre decision to choose a restricted access rig for a project in which space is no issue. This would simply be incredibly inefficient and draw the job out far too long.

Do you need a larger rig…?

Immense performance capabilities can be found in percussion and sonic drilling rigs. As larger rigs, they are understandably perfect for larger jobs, but which would be the best drilling rig to hire?

Any jobs involving rocks of a soft to medium hardness (such as limestone) would be a good fit for rotary drilling. The same can be said for boreholes requiring a relatively large diameter. This form of drilling is frequently used in a quarry setting. Percussion drilling – be it regular or cable – on the other hand, is ideal for either consolidated or unconsolidated formations, including clays and sands. Shallower settings may call for the efficiency of auger drilling, whilst sonic drilling offers incredible power and an especially clean job. The latter is primarily suited to both soft and hard formations in overburden conditions. Sonic drilling is, in fact, one of our personal favourite methods of drilling here at Borehole Solutions!

…Or a smaller rig?

Such large and powerful machines aren’t always necessary, however. For certain projects, you would be much better off looking for a smaller drilling rig to hire. Do you need a quick soil sampling, for example? In which case, a window sampling option would be ideal. Easy to use without a need for extensive training, handheld window sampling equipment may be all you need. This begs another question though; are you trained to use the equipment you need? In many cases, this may not be the case, meaning you should hire the company alongside the rig.

Consider the cost!

No matter what you really need, cost must always be considered! We’re sure you don’t need us to tell you that, or that you will be paying for both size and quality. This is why sonic drilling rigs are the most expensive to hire and, similarly, why smaller handheld equipment, and the like, is much cheaper. It’s not possible to provide exact figures as this ultimately comes down to a variety of different factors, such as the length and purpose of the hire, breakdown cover, etc. You can find out more about these cost factors in another blog post, here!
