Lifting a 40-year-old U.S. ban on crude exports would create a wide range of jobs in the oil drilling supply chain and broader economy even in states that produce little or no oil, according to a report released on Tuesday. Only 10 percent of the jobs would be created in actual oil production, while 30 percent would come from the supply chain, and 60 percent would come from the broader economy, the report said. The supply chain jobs would be created in industries that support drilling, such as oil field trucks, construction, information technology and rail.
