U.S. says energy companies not sharing test data on Bakken oil

|By:, SA News Editor

The Transportation Department says only three companies - Exxon Mobil (XOM), Continental Resources (CLR) and Savage Services - have voluntarily turned over data on the physical characteristics of Bakken crude oil from North Dakota, despite requests for the information dating back to January.

The government is seeking data on Bakken crude after a series of railroad accidents in which oil exploded; historically, crude hasn't erupted into fireballs, raising questions about the composition of the oil from the Bakken.
