What is (Horizontal) Directional Drilling?
Horizontal Directional Drilling is a way to install underground pipes, conduits and cables in an arc along a specific path by using a steerable drilling rig. It’s used when overhead installation, trenching and/or excavating isn’t practical from a cost or permitting standpoint. Not only does Horizontal Directional Drilling offer a low level of impact on the surrounding environment, but it may be required to meet federal regulatory or local permit requirements.
What wire is used for Directional Drilling?
There are two wires commonly used in Directional Drilling:
- Horizontal Directional Drilling Wire (HDD): Often called the ‘wireline,’ HDD is used in directional drilling when a wireline monitoring system is needed, rather than an above-ground, or ‘walk-over,’ monitoring system. The wire runs inside the drill string and transmits information on the angle, rotation, direction and temperature of the drilling head while it’s working underground, out of sight. It’s manufactured to withstand the harshness of the drill pipe process and deliver reliable electrical signals to the guidance control.
- Directional Drilling Tracer Wire: This wire works the same way that traditional tracer wire works, but is made of a more durable insulation able to withstand the harsher environments associated with the drilling process. This guarantees that your tracer will still be in one piece when you need to use it. Drilling and pulling back only once is always the low cost answer!

At the request of an OEM manufacturer of guidance systems and directional steering equipment, we’ve developed a steering wireline product specifically designed for the HDD industry. We’ve also developed special high-breaking strength cables to withstand the critical “pull-back” of pipe after all the drill work is done.
