Need and Applications of Directional Drilling and Its Equipment
Directional drilling, also known as slant drilling is a process of drilling non-vertical wells. It is also defined as the practice of controlling the direction and deviation of a well bore to a predetermined underground location or target. If you are wondering what is directional drilling, why it is required and what type of directional drilling equipment are used, this blog is for you. In this blog, we will be sharing all the details you need to know about directional drilling.
It was seen that utilizing the suite of technologies would ensure productivity. The first realization was that water wells or oil well are not vertical. This realization did not grasp the attention of the oil industry until late 1920s. The realization led to the introduction of directional drilling equipment to make the job easy and effective.

Applications of Directional Drilling
Listed below are some of the major applications of directional drilling.
Sidetrack- The sidetrack technique can be employed either to reposition the bottom of the wellbore or drill around obstructions. A blind sidetrack can be used to drill around obstructions such as a lost string of pipe.
Relief-well drilling- An uncontrolled well is intersected near its source to which mud and water are then pumped. For this kind of application, directional control is extremely important.
Inaccessible surface locations- A well is directionally drilled to reach the zone which is otherwise inaccessible with normal vertical-drilling practices. The location of a producing formation dictates the remote rig location and directional-well profile.
Fault drilling- When it is difficult to drill a vertical well through a steeply inclined fault plane, the wellbore may be deflected parallel or perpendicular to the fault for better production. In areas, where there is instability, a wellbore drilled through a fault zone could be at risk because of the possibility of slippage or movement along the fault.
