6 FAQs about [Rock drill supporting special pipeline diagram]

Is horizontal directional drilling the answer to your pipeline installation project?

When installing underground pipelines near unique land areas, horizontal directional drilling is a surefire way to minimize the negative environmental impact. Let’s take a closer look at why this trenchless technology may be the answer to your next pipeline installation project with our complete Horizontal Directional Drilling Guide.

What are the 3 stages of horizontal directional drilling?

There are three main stages in the horizontal directional drilling process: pilot drilling, expanding the drilling point of entry, and pulling the production pipe. Let’s explore each stage in more detail below: How Does Horizontal Directional Drilling Work?

What is horizontal directional drill (HDD) pipeline installation method?

The Horizontal Directional Drill (HDD) pipeline installation method is proposed for the Project. Texas Eastern has developed this Best Practices Plan for HDD Operations (Plan) for planning and personnel involved in HDD operations.

What is a horizontal drilling rig?

The components of a horizontal drilling rig used for pipeline construction are similar to those of an oil well drilling rig with the major exception being that a horizontal drilling rig is equipped with an inclined ramp as opposed to a vertical mast. HDD pilot hole operations are not unlike those involved in drilling a directional oil well.

What is pilot hole directional drilling?

Pilot Hole Directional Drilling Pilot hole directional control is achieved by using a non-rotating drill string with an asymmetrical leading edge. The asymmetry of the leading edge creates a steering bias while the non-rotating aspect of the drill string allows the steering bias to be held in a specific position while drilling.

How does pipeline installation work?

Pipe installation is accomplished by attaching the prefabricated pipeline pull section behind a reaming assembly at the exit point and pulling the reaming assembly and pull section back to the drilling rig. This is undertaken after completion of prereaming or, for smaller diameter lines in soft soils, directly after completion of the pilot hole.
