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. Recently, interest has peaked in the vast quantity of untapped natural gas resources in the US, the reserves of which were inventoried in 2008 at 238 Tcf, with producers specifically targeting the nation's promising shale formations for this energy commodity.
Pipe Inspectors have a general, broad knowledge base related to the maintenance, inspection and repair of piping systems. One of the methods used to inspect piping systems is NDT (non-destructive testing), in which properties of the pipe are tested without causing any damage to the material. Some NDT methods include visual inspection, thermal imaging, ultrasonic, and magnetic testing. Pipe Inspectors should have a good understanding of state and federal regulations, and can be found working in a plant/refinery setting as well as in the field inspecting pipelines.
