Definition - What does Directional Drilling Equipment mean?
Directional drilling is defined as one of the practises of drilling an oil or gas wellbore in a particular direction usually in a “Horizontal Direction”. It is another approach of drilling non-vertical wells in which a wellbore is drilled vertically downwards up to certain depth and then this wellbore is further drilled in a horizontal direction with respect to the surface of earth.
Bracetool explains Directional Drilling
Directional drilling is also called as “Slant drilling” and hydrocarbon well formed from such drilling technique is called directional well. A primary reason for drilling a directional well is to exploit the hydrocarbon reservoir to the best possible extent which ultimately impossible with vertical well profile and vertical drilling practises. Some of the advantages of directional drilling are as follows:
- A wellbore can be scattered into various directions to touch scattered nearby hydrocarbon reservoirs, also called as “Pay Zones”. Only one wellbore is enough to reach to nearby pay zones or hydrocarbon reservoir if it is drilled directionally.
- A directional drilling ultimately removes the need of having vertical well profile for nearby reservoirs, thus, saves E&P organization investment and time.
- The inaccessible surface locations can be targeted with the help of directional drilling.
- Any harm to residential areas, natural resources such as rivers, forest, etc, are easily avoided when the well is drilled directionally as the wellbore can be deviated from these areas easily.
