TUBOSCOPE Oilfield Services Division ? Pioneer in
Non-Destructive Inspection of Oil Country Tubular Goods
The need for economical, effective inspection of oilfield tubular goods has been evident from the very beginning of oil well drilling operations. The extremely high cost of failure in drill pipe, casing, and tubing and sucker rods has been, and continues to be, a pressing problem for the petroleum producing industry.

Preventive maintenance costs a lot less than a drill pipe failure.
Today you're under pressure to maximize productivity .so you push the most expensive item in your operation ? your drill string-to its limit.unfortunately, the harder you push it, the more stress you apply to each length of drill pipe.
