They were only expected to get more intense, and they have. Worldwide,  , as a Bloomberg story mentioned. The problem is that the oil industry interconnects with many others. Production requires equipment, which uses steel and other metals. Professionals buy and sell commodities. Refineries tend to specialize in certain qualities of oil. Slow product of something like tar sands oil and all sorts of companies that feel the pinch might start layoffs.  "There's not many industries where a guy  , but that's a common pay package for drilling rig workers," wrote Forbes staffer Christopher Helman. "I'm told by people who operate a lot of drilling rigs that for every rig mothballed about 40 people lose their jobs. The U.S. rig count is down by more than 700 from this time last year."
