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.
Surveying can mean several different things as it relates to the oil and gas industry. When discussing oilfield surveying, this usually refers to checking and creating the legal boundary for drilling operations. Surveyors will use a variety of techniques including GPS systems, hand tools, and sketches to create such boundaries. Surveyors may also be responsible for checking ownership of properties, and registering any updates with the proper legal authorities. Surveyors typically spend most of their time in the field and will travel extensively for these positions.
