How Horizontal Directional Drilling is Done – Source and Resource

A drillbit follows a planned path across long distances. However, different geographic formations need various equipment.

An example is that an alluvial (or soft) formation employs high-pressure water from a jetting assembly for clearing its way while drilling. To ensure that the correct direction is taken the tool for steering transmits information to the navigator.

The nozzle concentrates the on the hydraulic pressure, which causes it to shift direction. The drill moves along until it’s in its proper place. When the driller is happy and is satisfied, the driller will continue making the same rotations as usual.

A drill motor is used as a replacement for the jetting device for more difficult formations. Instead of rotating the drill string, the mechanism is turned by a turbine. This is the turbine that lets the driller’s point toward the proper direction. The data on steering is collected and adjustments are made on periodic intervals.

Horizontal boring is a complicated process that calls for advanced industrial tools and workers that have the necessary experience and know-how. Horizontal boring can be explained in detail by clicking on the video.
