Considering the importance of learning Horizontal Directional Drilling process, we are going to explain what exactly horizontal directional drilling is and how an experienced directional drilling company like Underground Installations in Australia can justify with their job. 

Knowing the process –

HDD or Horizontal directional drilling is all about the installation of underground cables, pipelines and conduit service via trenchless methods. In HDD process, the operator uses a drilling machine with some attachments or accessories. With a complete directional drilling device, the operator precisely drill along a selected bore route and back ream a needed pipe. 

There are mainly three stages to complete the horizontal directional drilling and following mentioned those steps. 

Pilot Hole In Horizontal Directional Drilling

This is the first and the most important step of HDD as it involves to drill a pilot hole of small diameter. The operator pumps the drilling fluid from the pipe to the bit where the powerful jets with high pressure as well as bit grind soils before the stem of drill. The fluid of drilling also carries all kinds of cuttings and take it to pit entrance at the rig. 


The pilot hole tracking depends on varied aspects like complexity and size of shot as small shots can be performed with the walkover guidance solution; however the large shorts are done with a magnetics type wire line system. Both of these methods involve a steering tool or transmitter placed near the head of drill that sends signal over the engineer location and helping in the precise coordination of the stem. The operator keeps on taking readings that are about depth, percent slope and alignment of the head of drill.
