Certified Courses on Drilling Technology

Technoscan is one of the leading oil and gas training institute Ernakulam, Pathanamthitta, Kerala and Nagercoil. What is Drilling technology?. The well is created by drilling a hole12 cm to 1 meter (5 in to 40 in) in diameter into the earth with a drilling rig that rotates a drill string with a bit attached. After the hole is drilled, sections of steel pipe (casing), slightly smaller in diameter than the borehole, are placed in the hole.

Cement may be placed on the outside of the casing and the borehole known as the annulus. The casing provides structural integrity to the newly drilled wellbore, in addition to isolating potentially dangerous high-pressure zones from each other and from the surface.
With these zones safely isolated and the formation protected by the casing, the well can be drilled deeper (into potentially more-unstable and violent formations) with a smaller bit, and also cased with a smaller size casing. Modern wells often have two to five sets of subsequently smaller hole sizes drilled inside one another, each cemented with the casing.
This course offers various steps and techniques used in well drilling in detail.
