Directional Boring Techniques and Precautions

January 15, 2021

Construction, oil, and gas industries can utilise different drilling methods for them to access the underground surface. However, one specific method has been prevalent for the mentioned industries due to its accompanying benefits and features. This method is known as directional boring.

Overview of Directional Boring

Directional boring is a steerable trenchless process that allows industries to introduce underground pipes, cables, or conduits through a surface-launched boring component. This specific process can be utilised by the oil and gas industry when it comes to drilling various wells and forming a vertical well hole. Alternatively, the construction industry maximises this process in terms of installing utility pipelines and conduits. Directional boring can also be used in making crossings under rivers, roads, and old structures. 

What is great about directional boring is that it can serve as a perfect substitute to trenching and exhuming. It can likewise work well with any types of soil conditions and application requirements. Directional boring can also reduce soil disturbance, contamination of groundwater, and costs of excavation, protect the environment from damages, and limit traffic and landscape disruption.

Directional Boring Techniques

Holes are normally accessed through pointing the trenching or drilling tool towards the intended bore path. Directional boring, alternatively, utilises a curve that is close to the bit. It also has a downhole steerable mud engine, which can be used to navigate without drill string rotation.

During the directional boring, the curve can control the bit in an alternative heading once the whole drill string is not turning. Once the desired angle is reached, the drill string will then be rotated alongside the bend. This movement ensures that the drill bit will not bore in other direction from the wellbore pivot.

Involved Risks and Precautions 

The security and health of the people on site are some of the elements that can be affected by directional boring. Additionally, the said boring process and its results can likewise affect underground resource owners, people who are responsible for the work environment, utility suppliers, and the local government.

One of the risks involved in directional boring is the interference of various businesses on the project. The safety and wellbeing of people onsite and around the area are also considered to be part of the risk of the process. To minimise these risks, underground resource owners must give drawings to all involved stakeholders and follow them thoroughly. Organisations must also conduct a complete risk appraisal. Physical confirmation of buried services must likewise be done for smoother directional boring process.
