Drilling along the chosen line of bore, and then back-reaming the necessary pipe using an instrument for directional drilling as well as other equipment.

Drilling a pilot hole with a small diameter is the initial stage. Drill bits and high-pressure jets cooperate to grind the soil on the other side of the shaft. Drill fluid is then fed through the drill pipe into the drill. Drilling fluids will transfer the waste from drilling back to the drill rig’s entry pit.

Due to the fact that this involves pipes directionally drilling contractors must follow the procedure with utmost care. If this procedure isn’t followed properly it could cost more money.

Based on the dimensions and the complexity of the picture There are a variety of methods to track holes for the pilot. A walkover guidance system is suitable for shorter shots, whereas a wireline magnetics type system is used for larger, elaborate shots. All the time, the drilling stem’s precise coordinates are sent to the location engineer via a transmitter or steering tool which is located within the vicinity of the drill. It is also possible to continuously track the drill’s depth, alignment, and % slope.

Operator and locator adjust holes to conform to the bore’s course.
