With development in the drilling and construction industry, major changes have been observed in the drilling techniques used world wide. Horizontal Directional Drilling (HDD) is popular among the contractors because it is time saving, requires less resources and feasible in areas where other techniques possess a risk or threat to the surrounding environment. In this piece, We-Bore-It provides a comprehensive take on what HDD is all about and how it is performed.

1. A Complete Guide To
Horizontal Directional Drilling

2. What is HDD?
Horizontal Directional Drilling is a system of drilling,
installing or replacing the new pipes under the ground
without digging the full ground.
It is also called as Directional Drilling, Trench-less Method
or HDD.

3. Introduction
●
This type of drilling is done by the drilling rigs.
●
It is time saving and doesn’t disturb the land.
●
It is used in many projects of pipe fixing, such as the electric,
water, gas pipes, telecommunication pipes, sewer pipes and
many more.
●
It is environment friendly and doesn’t cause any damage or
destruction to the landscape.
●
The work is completed by using different equipments and
workers without jamming the traffic or crowding the place.

5. Method of Horizontal Directional
Drilling
●
In this method the group of workers is very small.
●
The working equipment includes only a drilling machine
and the tracking operator. These are connected to each
other electrically.
●
The drill fluid helps in starting the drilling of the hole in the
ground.
●
The drill fluid keeps checking the ground for the type of the
land and the stability of the hole.

7. ●
The drill always moves in the arc shapes and exits at the
end of the arc from the ground area.
●
Then the reamer is entered which is according to the size
of the pipes and makes a clear path for the pipes.
●
The pipes are entered and fixed and they are heated to
connect to each other.

8. Tools & Equipments Used in HDD
●
MWD (Measuring while drilling) sensors
●
Mud Motors
●
BHA configuration
●
Drill bits
●
Whip stocks

9. Pros of HDD
●
Doesn’t disturb the area around the
project
●
Saves money and cost of excavation
●
Very safe technique
●
Work is not delayed due to improper
weather conditions
●
Doesn't disrupt traffic
●
The work done is neat and faster
●
Saves a lot of time
●
Flexible method and can be installed in
any area

10. Cons of HDD
●
HDD technique has high rate of
collapsing
●
It can be costly for certain
projects
●
Work limitation issues due to
cobbles and stones scattered
on the ground
