Directional Drilling #
During the earlier days of drilling, wells were drilled directly above the target reservoirs. Wellbores were channeled vertically to hit the target depth. There were a lot of untapped reservoirs, so exploration was limited to the most accessible reserves.
But as reserves continue to decline and oil and gas exploration becomes more complex, the need for an alternative method of drilling has arisen over the years.
Directional drilling is an alternative means of accessing oil or gas reserves by drilling through a non-vertical pathway.
It allows entry into multiple oil reservoirs from a single wellbore, thereby decreasing operational costs. Another advantage of directional drilling is the opportunity to hit your target reserves from a reasonable distance at the surface; this lessens the environmental impact of drilling.

How far can it go? #
There are numerous factors that determine the maximum depth you can achieve using directional drilling. But on average, wells of 10,000ft- 15000ft can be drilled using this method. Under favorable conditions, up to 25000ft is achievable.
How much does it cost? #
The cost of directional drilling varies depending on the project, location, reservoir properties, well depth, drilling plan, and a host of other factors. Pricing may be done on a lump sum basis or per foot.

What are the limitations of directional drilling? #
High cost of operation
High cost of equipment.
Increase in drilling complexity.
But in all, its pros outweigh its cons.
