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.
Piping engineers apply the principles of mathematics, physics and chemistry to assure the design of pipe systems used to convey liquid or gas from one location to another. Specialists in this field may focus on materials, design or stress analysis, and they ensure that piping systems are designed, fabricated, installed, inspected, operated and maintained. This is extremely important to the safety of personnel, public safety, and facility reliability.
