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)
