The Different Types of Environmental Drilling

In this blog post, I will help you understand some of the things you should learn about the different types of environmental drilling services. There is no need to have in-depth technical knowledge to understand these drilling jobs. Each of its different types have their own pros and cons and they are also applicable in specific projects. It is important for environmental drilling companies to give their clients expert advice on how one method is different from the other, and in the end, make a recommendation with regards to which one is the best for a specific job.

Auger Drilling

In the most primitive form of auger drilling, which has been recorded 3,000 years ago in China, drillers make use only of ropes and bamboo to bore holes. Before the introduction of modern equipment for auger drilling, people were using rods that are turned either with the use of their hands or with the use of animals. Fortunately, environmental drilling companies have made significant investments in new technologies to make sure they can complete any job successfully. One of the contemporary machines available is the continuous flight auger, which makes use of a rotational head to drill. This type of drilling offers the benefit of being low cost but has the drawback of being applicable only in softer surfaces or weaker materials.

Sonic Drilling

This is another drilling method companies utilize in the completion of environmental investigation services. This is one of the most contemporary approaches in drilling and is characterized by the collection of core samples with the use of precision and speed. According to experts, one of the reasons on why this is a preferred methodology is the fact that it leads into a very minimal compaction and disturbance in spite of being a very powerful drilling method. Other advantages of this method include proceeding even without the use of drilling fluid and being applicable even in unconsolidated formations. However, one of its drawbacks is its limited availability because of being relatively new and its expensive price compared to other methods of environmental drilling.

Rotary Drilling

Also known as direct drilling, a constantly rotating bit is being employed for the purpose of penetrating to any type of formation that can be found even 1,000 feet under the ground. It has a rotation speed that can be adjusted based on the hardness of the surface. Many companies use this for their drilling services because of their high penetration rate and rapid mobilization and demobilization. On the other hand, many have expressed concerns with regards to how it makes use of a drilling fluid and how it can be challenging to gather accurate samples.

Aside from those that have bene mentioned above, other types of drilling commonly used for environmental investigation include displacement boring, reverse circulation rotary drilling, dual-wall reverse circulation drilling, and cable tool percussion, among others. It is important to have a thorough conversation with the drilling company in order to know the differences between each method and decide which one is the most appropriate for the job you will need.
