Directional drilling

Directional drilling. To install a pipe under an obstacle without without disturbing the surrounding area.

Contrary to horizontal drilling, the curbed trajectory of directional drilling makes it possible to pass the conduit under obstacles starting from the surface, thereby requiring no significant excavation.

Our experienced technicians use high-performance guiding systems, making it possible to have great precision and to ensure the drilling trajectory. We have a complete array of equipment designed to meet the needs for all types of projects requiring directional drilling.

Expertise and cutting edge equipment to conduct all types of directional drilling jobs.

Using our equipment, we can undertake simple drilling projects requiring a pull back strength of less than 10,000 pounds, as well as major projects requiring a pullback reaching up to 750,000 pounds such as more than one kilometre of drilling under a river in the rock. Moreover, our recycling unit for drilling mud provides more effective performance and considerably reduces the amount of drilling mud to be disposed of at the end of the project.

Possible applications of directional drilling.

Regardless of the nature of the obstacle to be overcome and the diameter of the conduit to install, we have the expertise and technology to fulfill all your directional drilling needs. It should be noted that this technique is ideal for:

  • Soils that contain no rocks or blacks (clay, silt and sand)
  • Almost all categories of rock
  • We have installed pipes up to 42 inches of diameters and a length of 3 000 feets

Making it possible to drill distances up to 1,800 metres in length (which varies according to sail conditions and the diameter required} and we are ready to meet new challenges.

We have carried out many directional drilling projects for the installation of gas lines, water supply, electricity, sewer or optical fibers. Possible applications of directional drilling are numerous. We present you a few examples:

Urban drilling (without interfering with traffic)

  • Drilling through a park at Carlton University in Ottawa: 285 m 14in HDPE pipe
  • Drilling under highway 40 in St-Augustin-de-Desmaures : 95m steel pipe 18 inches, 24inches bore in the rock
  • River crossing in sensitive environments
  • Drilling under the Rivière des Prairies in Montreal in the rock: 900 meters 24inches steel pipe in a 36in bore
  • Length of the borehole has no impact on accuracy

Installing emissary and water intake (without disturbing the shore of the river)

  • Water intake at Thetford in 2011 under winter conditions
  • Emissary on Cote Fréchette in Lévis, 2009
