Horizontal Directional Drilling


Process

  • Guided pilot hole is drilled along a bore path under the obstruction, or per the required alignment
  • Drilling fluids are used in the bore hole to stabilize and lubricate the operation
  • Various reamers may be used to enlarge the pilot hole
  • Multiple passes may be required to accommodate the required pipe OD
  • Drilled bore hole is typically enlarged to 1.5 x OD of new pipe
  • Joined pipe is pulled back after bore hole preparation is completed
  • Drilled holes are stable for a limited time. Entire fused lengths are typically pulled in at one time, with no interruptions
