Regulators step up inspections of crude oil shipped by rail from Bakken field

After several major train accidents and fires involving crude oil from the fast-growing Bakken field in North Dakota, federal regulators stepped up rail inspections and issued a safety alert Thursday that Bakken oil could be more flammable than other types of crude.

The news affected shares of several large Bakken operators, including Oklahoma City's Continental Resources Inc. On a day where all major U.S. stock market indexes also fell, Continental shares were down 4 percent. Shares in EOG Resources Inc. dropped 2 percent.

The Pipeline and Hazardous Materials Safety Administration and the Federal Railroad Administration said they were increasing unannounced inspections and testing of trains carrying Bakken crude to make sure safety rules were being followed. The inspection program started in November.

The safety alert said shippers should properly test, characterize, classify and sufficiently degasify hazardous materials before and during transportation.

“PHMSA expects to have final test results in the near future for the gas content, corrosivity, toxicity, flammability and certain other characteristics of the Bakken crude oil, which should more clearly inform the proper characterization of the material,” the alert said.

Rapid development in the Bakken has outpaced pipeline infrastructure and crude oil is increasingly being transported by rail. Railroad tank cars are filled by either direct loading from a cargo tank or from bulk-storage tanks that may contain crude from different operators.

Continental said its testing shows Bakken oil has a lower sulfur element and a lower percentage of light ends — more volatile products — than West Texas Intermediate crude and other common oils. The company said it supported the more rigorous testing suggested by the federal safety alert.

“We have no way of knowing what other crudes, such as oil from older, non-Bakken wells, might have been blended with true Bakken oil, or otherwise how the oil has been handled and loaded post-sale,” said Warren Henry, Continental's vice president of investor relations. “It's completely logical to step up the testing and make sure product transported by rail is safe and properly loaded.”
