COTS started to provide DD services from 2007, accumulating rich experiences so far. 

Controlled directional drilling is the Technology 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
