Oil rigs are incredibly complex machines with a dizzying array of production equipment that must meet the needs of regulators while providing as much oil as possible. Previous generations relied on human observers to oversee these systems, but new technologies are increasingly being used to ensure that rigs are working at peak efficiency. As the “digital oilfield” becomes the norm, rig operators have begun seeking sophisticated tools to detect leaks and ensure mechanical integrity. One of the most popular innovations involves Wireless Sensor Networks (WSNs).
