    Oil Country Tubular Goods (OCTG)

    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)

    Tubing Pipe - Seamless Steel Tubing manufactured to API 5CT

    Specification Latest Edition, EUE Threaded and Coupled

    Casing Pipe - Seamless Steel Casing manufactured to API 5CT
