Directional Drilling

A drilling technique in which a well is bored to multiple angles. Directional drilling refers more often for the non-vertical angle drilling, including horizontally. It is used both to recover oil and natural gas underground, and is useful in situations where the shape of the tank is abnormal. It is also used to adjust pressure created by the gas in mines (degassing).

As a technique, directional drilling allows oil and gas operators to approach a potentially productive zone, without the need of a well to be drilled directly above that area. A central site can serve holes that reach more and more to non-vertical angles positions. This reduces the number of facilities and which must be constructed and maintained. With no need to build new wells may also lead to the exploration of smaller fields that would otherwise be uneconomical.

Early involved directional drilling tip of the tip with a different vertical angle, resulting in a straight line away from the well. The modern drilling techniques allow the use of tips that can bend; allow engineers to adjust the direction of the well is drilled to a certain extent. This can be accomplished through the use of hydraulic jets

Directional drilling is used in the development of mines, in order to reduce the risk of potentially dangerous gas breakages. In-mine drilling techniques allow companies to create holes in advance of my face.

While the basic concepts of directional drilling date back to the 19th century, has become a popular technique such as computer technology has become more common. The toe angle used for bored shaft can be regulated by a computer using GPS signals to pinpoint the location of an oil and gas field. Engineers create the 3D field models to determine the best location for good, and the best approach to the hole to follow.
