What is Directional Drilling? 

Construction and oil extraction companies often use the technique of Directional drilling, also called directional boring, to access oil in underground reserves and install pipes. Unlike the traditional drilling process, in this method, drilling is performed at a non-vertical angle with a very small degree of angle changes over long distances to keep the bore path in the desired direction. Any drilling technique that does not involve straight-down excavation is called directional drilling. The fundamental advantage of directional drilling is that it enables businesses to access several conduits or oil reserves from a single entrance point, saving overall drilling costs and minimizing drilling's negative effects on the environment.

Directional Drillers' expertise in horizontal directional drilling is improving and expanding every year. We are constantly upgrading ourselves technically, managing risks more efficiently, and drilling installations faster. No matter how remote the project is located and how challenging the terrain is, we will help you resolve it effectively and rapidly.

Stages Involved in Horizontal Directional Drilling

Directional Drilling Vs Other types of Drilling

In contrast to conventional drilling methods, directional drilling enables you to choose the entrance's location and control its horizontal direction. It makes areas accessible that would otherwise be impossible to get to using traditional techniques. It also allows access to multiple target locations from a single entry point. Trenching and drilling are both forms of excavation and not drilling techniques. While trenching is ‚Äča straightforward method used to excavate from above for laying cables, HDD makes tunnels in the ground for new cables non-invasively. Compared to conventional drilling methods, Directional Drilling leaves the soil and assets underneath unaffected.  

Lesser disruptions

Large-scale drilling using big machines always causes public disturbance and disruptions. In Directional Drilling, these machines can be placed far away from high-traffic areas and execute the process without affecting public life, and traffic and eliminate any safety hazards.

Safe for workers and public

Unlike the traditional drilling process, there are no open pits that a machine or a person can accidentally fall into. Drilling using HDD machines largely eliminates elements that can become death traps like wall collapses due to the weakening of structures because of loose ground.  

Lesser soil disturbance

In directional drilling, it is possible to drill a pilot borehole and estimate a predetermined bore path from the surface to the desired location. A professional and experienced directional drilling team can supervise and decide on the desired horizontal bore path.

One location, different installations 

In directional drilling, it is possible to drill a pilot borehole and estimate a predetermined bore path from the surface to the desired location. A professional and experienced directional drilling team can supervise and decide on the desired horizontal bore path. Doing this help reduce surface damage and stay within a budget.

Reduction in excavation and shoring costs

In directional drilling, since no soil is excavated to construct a trench, construction expenses are significantly reduced. This further reduces the expenses involved in shoring, which is necessary to prevent the trench from collapsing.   

Mitigating weather impacts on excavation  

The budget of a project is substantially impacted by delays caused due to bad weather. Additionally, excessive rain can also make the trench walls unstable and dangerous. While trenching operations are often halted by rain, horizontal-direction drilling-based underground projects will not be drastically affected.
