Spanning Canada and the United States, North America is home to a plethora of major industry players, including Exxon Mobil Corp, the world's second-largest publicly traded company after Royal Dutch Shell. The region's oil and natural gas industry is focused on developing oil sands, deepwater gulf prospects and increasingly profitable shale deposits stretching across the continent. One of the premier sweet spots for deepwater exploration, the Gulf of Mexico is the largest body of water indenting the U.S. continental coastline, and its subsea developments continue to spark both national and international interest.
In general, process control refers to maintaining the output of a specific process within a desired range. Process control also enables automation, which allows a smaller staff to control a large operation. In the oilfield, many operations are run by process controls including valves, mud pumps, vessels and instruments. Testing and monitoring of systems can also be automated. Jobs in this field vary from engineers responsible for designing and programming equipment, to technicians responsible for maintenance and monitoring of control systems.
