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.
Instrument & Controls engineers design, install, manage, and maintain equipment which is used to monitor and control engineering systems, machinery and processes. Instrumentation is vital in measuring and controlling parameters such as pressure, flow, temperature, current, and voltage by gathering information from the field and then changing its parameters via a control loop. Instrument & Controls engineers therefore aim to improve productivity, stability, safety, continuity and optimization through measurement, automation and control processes.
