Everything You Need to Know About Directional Drilling


Horizontal boring, also known as directional drilling, is one of the most common methods used by companies for installing underground pipes or conduits. It is a trenchless method that has steering capabilities and is mainly used throughout Australia for installing underground pipes or cables. A drilling rig is used that is launched from the surface, and the ultimate aim is to minimise the impact on the surrounding area. For instance, if there’s a ready-built street and landscaping in an area, this trenchless method of drilling might be used in order to lay down underground pipes or cables.

The pipes can be made from a variety of different materials, including PVC, polyethylene, ductile iron, steel, or even polypropylene, offering a considerable amount of variety. However, before directional drilling can be carried out, a geological survey of the area must be conducted. If there are voids in the rock or if the layers are not complete, then directional drilling is not a practical method. A number of different companies . If you are a contractor and need some underground drilling work done, you should check online for a list of local companies that offer directional drilling.

Ideal Situation

The best material in which directional horizontal drilling can be carried out is solid rock or sedimentary material. If the soil has smaller cobblestones in it, then this method of drilling is not a useful choice. Before the drilling work begins, a specialist will analyse the type of rock in which the drilling is to be conducted and then determine the pilot head that should be used. Usually, a number of different types of pilot heads are used throughout the process depending upon the material.

Equipment Used

The equipment used in directional boring usually varies on a number of factors. For instance, the conditions in the ground, the diameter of the pipe to be used, the surrounding area above the ground (ease of access), and the length of the pipe to be installed all play a role in selecting a particular type of equipment.

Apart from the boring equipment, mud reclaimers, and excavators, a number of pipes and hoses are used to ensure that a constant supply of drilling fluid is maintained all the way throughout the drilling stem. Heat-treated carbon steel is most commonly used for making the drilling stem so that it doesn’t break under pressure and to ensure that the weight of the drilling stem does not exceed the provided limits. If the work requires a smaller bore, most companies prefer using portable equipment only, and there’s no need for using additional hoses and pipes, ensuring that the work is completed quickly.
