Drilling Applications :
- Gas and
oil pipelines : A major use for
HDD is installing high pressure gas and oil pipelines under obstacles like
waterways, airports, and major roads and other large natural features or urban
structures. By putting the pipeline deep underground, often in solid rock, it's
protected from damage by dredging, anchors or surface trenching. It also
protects it from accidental or deliberate damage, helping to manage risk and
eliminate threats to the pipeline.
- Water
and sewerage : As with gas and
oil, HDD can be used to carry water and sewerage pipelines under and around
almost anything. Lucas has also used HDD to drill directly into deep
underground sewer tunnels. Apart from avoiding the cost and disruption of
surface trenching, HDD's ability to maintain a precise gradient and travel deep
underground has dramatically reduced the need for pumping stations, simplifying
the sewerage system and reducing long-term costs.
-
Telecommunications : As well as
carrying conduits for fiber optic cables beneath rivers and other obstacles,
Lucas has used HDD to carry them to near-inaccessible mountain tops and
microwave transmission towers. By placing them deep into bedrock beneath the
coastal sands and surf zone, these fiber-optic cables are protected in the most
vulnerable part of their route.
- Power : High-tension
cables can be placed deep underground, protected from damage and avoiding
surface obstacles.
- Environmental protection and remediation : HDD
has a wide variety of environmental uses: draining landslip-prone hillsides,
extracting methane gas from coal seams before mining, restoring sand to
beaches, creating underground barriers to reduce movement of contaminants,
draining slag heaps and rubbish dumps.
Directional Drilling Objective
Purpose: Install utilities (Pipes & or
cables) underground, without disturbing ground surface.
