Directional Drilling

Excavation is an essential aspect of various industries, from construction and oil exploration to telecommunications and utilities. However, traditional excavation methods can be inefficient, time-consuming, and risky. That’s where directional drilling comes in.

This drilling technique, also known as horizontal directional drilling (HDD), is a modern excavation method that offers many benefits over traditional methods. Hydrovac Calgary has been offering clients this service for more than 7 years now. We have the latest equipment and experienced crew to take on any directional drilling job.

What is Directional Drilling?

Directional drilling is a trenchless excavation method that involves drilling a horizontal, curved or angled hole underground, rather than digging a trench. The drilling process uses a steerable drill bit that can change direction as it bores through soil, rock, or other materials. A drilling rig on the surface controls the drill bit, which also monitors the drill’s progress, adjusts its direction, and controls its speed and torque.

How Does Directional Drilling Work?

This drilling process begins with drilling a pilot hole, using a small-diameter drill bit. Once the pilot hole is complete, a larger reaming bit is attached to the drill string and pulled back through the hole to widen it. This process repeats several times, with progressively larger reaming bits, to achieve the desired diameter.

Another use of directional horizontal drilling is to create underground passages for various purposes, including:

Installing pipes, cables, and conduits for utilities and telecommunications

Extracting oil, gas, or minerals

Creating geothermal wells

Building tunnels and underground structures

Directional Drilling

Uses of Directional Drilling:

This drilling method has numerous advantages over traditional excavation methods, making it a popular choice for many industries. Some of the uses of directional drilling include:

Utilities and Telecommunications:

Directional horizontal drilling is a preferred method for installing underground utility lines, such as water, gas, and electric pipes, as well as telecommunication cables. This method allows for minimal disruption to the surrounding environment, reduced restoration costs, and improved safety by avoiding the need for trenching.

Oil and Gas:

This drilling method is a vital technique in oil and gas exploration and production. It allows for access to reserves located under water bodies, urban areas, or environmentally sensitive regions, reducing the need for surface disturbance and minimizing the environmental impact.

Geothermal Energy:

Directional drilling is an essential tool in geothermal energy production, allowing for the creation of wells that can access hot water and steam resources deep underground.


Directional drilling can be used to create underground tunnels and structures, such as subway systems, sewer lines, and water pipelines, without disturbing the surface or the surrounding environment.

Q: Is directional drilling safe?

A: Yes, directional drilling is a safe excavation method that poses minimal risk to workers and the environment.

Q: How deep can directional drilling go?

A: Directional drilling can reach depths of up to several kilometres, depending on the geology and the drilling equipment used.

Q: How long does directional drilling take?

A: The duration of directional drilling depends on various factors, such as the distance, depth, and diameter of the hole, as well as the soil and rock conditions. However, directional drilling can be completed faster than traditional excavation methods, reducing project timelines and costs.
