Finding the Right Drilling Rigs for Different Drilling Jobs

Drilling has been practiced since time immemorial when ancient civilizations searched for natural resources such as minerals, water, and other elements for survival. Though the concepts remain the same, the method and the equipment used have changed remarkably over the years. Today, massive drilling rigs equipped with innovative technologies are being used by different industries for various purposes, such as water well drilling and oil exploration. 

What Are the Types of Drilling Methods and Drill Rigs?

The type of rig or drilling technology contributes to the overall success of any drilling operation. A rig can only be effective in a particular terrain it will be operating on. That is why it is necessary to determine what it will be used for in order to make the best choice and yield good results.

  • Rotary Drilling

With a significant depth of up to 5,000 meters, rotary drilling is ideal for soft rock type of soil and is mainly used for oil production where it grinds the rock to dig a hole using a tool under the effect of weight and rotation.

  • Down-the-hole Drilling

This rig can dig a hole with a depth of up to 4,000 meters, perfect for a terrain characterized by hard and cracked rock (limestone, granite). This style of drilling uses rigs that drill using a rotary cutter (drill head) and hammer the bottom of the hole with a pneumatic hammer. 

  • Top Hammer Drilling

This drilling method uses a rig that operates on a percussion system; however, it remains outside the borehole. This method is mainly used for small-diameter drillings, such as mineral exploration or the installation of tie rods in rock. 

  • Sonic Drilling

Sonic rigs are based on sonic technology that uses vibrating rotary drills to penetrate the soil. The drill bits of a sonic rig use an up-and-down motion where the soil particles that come into contact with the drill head are fluidized, resulting in reduced friction. 

Other common examples of drilling methods are Auger drilling, core drilling, percussion drilling, and pipe jacking. When it comes to types of drilling rigs, they can be classified as autonomous crawlers and truck or trailer-mounted.

The Do’s and Don’ts of Choosing the Right Drilling Rigs

For first-time drillers, selecting the right rig doesn’t really have to be an overwhelming task. You only have to make sure precisely what you plan to use it for and what kind of terrain it will be operating on.

The Do’s

  • Exactly identify the type of terrain that the rig will be working on.
  • Thoroughly check the condition of the equipment and its components to make sure it meets the required industry standard.
  • Consider the rig’s ease of use, safety, and reliability.
  • Make that you have adequate knowledge of proper maintenance.
  • Consider also the speed and power of the rig to ensure it will be efficient to use during a drilling operation.
  • Deal only with a reputable and trustworthy drill rig company.

The Don’ts

  • Making a decision hastily without conducting thorough research on equipment based on your drilling needs.
  • Buying used rigs without checking their condition properly. The maintenance cost and the chance of breakdowns can be higher than buying new rigs.
  • Lack of knowledge on how to maintain the rigs properly.
  • Dealing with a drill rig company with limited experience and expertise in the field.

Summary

There are plenty of options for drilling equipment that you may stumble upon on the internet. However, when finding the right equipment for your drilling business, it is vital to consider some factors in your buying decision, such as budget and other resources. 

Lastly, purchasing a piece of drilling equipment from a reputable manufacturer is crucial to ensure you get the best customer service and after-sales support. More significantly, you would like to know that the company you are dealing with will be around in times when you might need to repair and keep your drilling equipment running.
