Oil country tubular goods (OCTG) is a family of seamless
rolled products consisting of drill pipe, casing and tubing
subjected to loading conditions according to their specific
application. (see Figure 1 for schematic of a deep well):
Drill pipe is heavy seamless tube that rotates the drill bit
and circulates drilling fluid. Pipe segments 30 ft (9m) long
are coupled with tool joints. Drill pipe is simultaneously
subjected to high torque by drilling, axial tension by its
dead weight, and internal pressure by purging of drilling
fluid. Additionally, alternating bending loads due to non-
vertical or deflected drilling may be superimposed on these
basic loading patterns.
Casing pipe lines the borehole. It is subject to axial
tension by its dead weight, internal pressure by fluid
purging, and external pressure by surrounding rock
formations. Casing is particularly exposed to axial tension
and internal pressure by the pumped oil or gas emulsion.
Tubing is pipe through which the oil or gas is transported
from the wellbore. Tubing segments are generally around 30
ft [9 m] long with a threaded connection on each end.
Typical OCTG manufacturing processes include (all
dimensional ranges are approximate)
