As home to supermajors, as well as a plethora of smaller, independent energy players, the US boasts one of the largest concentrations of energy personnel in the world. With its insatiable appetite for energy resources, the United States is the world's single largest consumer of oil, using as much as 20.73 million barrels per day as of 2008.

NDT (Non-destructive testing) technicians evaluate the physical properties of a material without causing any damage. They will inspect and test the material to find any possible corrosion, cracks, or other imperfections which could alter its performance or integrity. The NDT technician will test material or parts in a number of ways including visual inspection, thermal imaging, ultrasonic or magnetic particle testing, among others. In the oil and gas industry, NDT testing plays a big role in manufacturing, as well as in piping and machinery inspections.
