Controlled
directional drilling is the science of deviating a well
bore along a planned course to a subsurface target whose
location is a given lateral distance and direction from
the vertical. At a specified vertical depth, this function
is the fundamental concept of controlled directional drilling
even in a well bore which is held as close to vertical
as possible as well as a deliberately planned deviation
from the vertical.
There are many applications
to drill a directional well, some important applications
are as following:
|
|
|
|
|
|
|
|
- Side-tracking
- Inaccessible Locations
- Salt Dome Drilling
- Fault Controlling
- Multiple Exploration Wells from a single Well-bore
- Onshore Drilling
- Offshore Multiwell Drilling
- Multiple Sands from a single Well-bore
- Relief Well
- Horizontal Wells
