Also known as “HDD (Horizontal Directional Drilling)” and “slant drilling,” directional drilling refers to drilling non-vertical bores to access underground oil or gas reserves. This practice involves a custom-designed drilling rig for drilling a pilot hole along a planned route between predetermined points.

Besides increasing the efficiency of O&G extraction, directional drilling results in a minimal impact on the environment compared to traditional drilling methods.

Here are the main types of directional drilling:

• Directional boring

• Oilfield directional drilling

• Surface in seam (SIS) drilling

• Utility installation directional drilling (for underground conduit installation, pipeline construction, etc.)

HDD (also known as “directional boring”) is commonly used as a safer, non-invasive underground utility installation method without open trenching for the entire utility length.

HDD includes a drill head to guide the drilling pipe and allows drilling under highways, waterways, and other critical infrastructure, and away from busy roadways or sidewalks.

For example, horizontal directional drilling services provide trenchless solutions for utility companies to install underground utilities, such as cables, pipes, and sewer lines.

In the O&G industry, companies specializing in directional drilling are essential for delivering a well to target with assured safety, greater speed, and lower overall drilling costs.
