API 5CT Certified Alloy Steel Seamless Casing Pipe For Oilfield
Well Drilling Project
Oil casing pipe descriptions:
Casing pipe is most often used in underground construction projects
to encase or protect utility lines
from being damaged.
Once a well has been drilled, if it is to become a production well,
the well must undergo completion.
While drilling a well cuts through the rock formations and allows drilling engineers to
reach the reservoir
below, the raw sides of the well cannot support themselves.
