Oil company officials laud findings on crude oil volatility

FARGO, N.D. — Preliminary research and comments by several federal agencies on the volatility of crude oil from North Dakota shows that Bakken crude has been unfairly singled out in safety discussions, oil industry representatives said Tuesday.

The makeup of crude oil from the Bakken formation has been at the forefront because of several fiery train derailments, including one in December 2013 outside Casselton that created a huge fireball and several explosions. Some regulators have said that Bakken crude is more flammable than other crude oils.

American Petroleum Industry spokeswoman Beth Treseder told oil company officials who were in Fargo for the North Dakota Petroleum Council’s annual meeting that several agencies appear to debunk that notion. She cited comments last week by National Transportation Safety Board Chairman Christopher Hart, who said volatility is not a significant issue.

“If it derails and the product is released, our accident experience has shown that the biggest contributor to a large explosion or fire is how much product is released rather than that volatility of the product,” Hart told Fargo radio station KFGO.

Treseder said findings by the Department of Transportation, Department of Energy and Federal Railroad Administration seem to point to the same conclusion. She said DOT officials told federal lawmakers that the vapor pressure of Bakken crude was “not outside the norm” for light crude oils.

“This wasn’t a surprise for anyone in the oil and gas industry, but having it said on the record in front of Congress was a step in the right direction, I think, for informing many other parities,” she told oil company officials.

“We’re trying to make sure that any regulations or requirements imposed are based on sound science and facts,” Treseder added. “API has been pushing very hard for this work to get done on a timely and complete basis so it takes into account real world conditions.”

North Dakota Petroleum Council president Ron Ness said the group has stated “from day one” that Bakken crude is not unique.

“Just like you saw in the ethanol fire down in South Dakota this week, there are many things that are flammable that go by communities and cities across this country every day,” Ness told The Associated Press as the council’s meeting was taking place.

Even so, the state of North Dakota passed new rules to reduce the oil’s volatility before it’s loaded onto train cars. Ness said state officials felt an obligation to “do everything possible” to prevent a catastrophe.

“We weren’t necessarily thrilled with the rules because we felt we were being singled out from every other crude oil in America,” Ness said. “But the reality is there’s more Bakken crude on the rails than anything else. We’ve got the rules in place, we’ve learned to live with them, we’ve made the investment and it’s happening.”

He said a better idea is to get more pipelines in place. North Dakota Pipeline Authority Director Justin Kringstad told oil company officials at the meeting that rail shipments are down to 47 percent of the oil moved out of state, compared to a high of 75 percent two years ago.

Kringstad said it will be until late 2016 or into 2017 before further pipeline projects are completed, so the amount of oil shipped by rail is not likely to change. He added that there’s no way to get oil to the West Coast other than by rail.

  1. Irregardless of the volume released volatillity dictates whether it ignites, burns or explode. Simple — compare train wrecks of Bakken light to wrecks with tar crude. One is very violatile with a high dissolved gas content– the other not violatile with almost no dissolved gas

  2. Actually; it’s the butane, propane, ethane, and other NGL’s left in the crude that are the cause of the explosions, but it suppose it’s been the oil (nine times).

    Have any oil trains exploded in the last half century that weren’t from the Bakken?

    Is unstabilized oil from other shale plays being shipped by train throughout ND & the rest of the country?


    “BNSF has followed the issue closely, (BNSF Executive Chairman) Rose said. That’s because the amount of volatile gas in crude oil determines how it needs to be carried, he said — and whether a newer tank car is necessary.

    “If you want to ship it (Bakken crude) with that (gases), then it needs to be in this type of tank car,” Rose said. “If you want to STABILIZE it, then quite frankly, it could probably go in the original (DOT-111) car.”–Columbian; 8/24/14
    “The state’s (North Dakota) three-person Industrial Commission seems likely to adopt a set of industry-designed best practices. Simply put, North Dakotan crude will have to be lightly pressure-cooked to boil off a fraction of the volatile “light ends” before shipment.”

    This conditioning lowers the ignition temperature of crude oil—but not by much. It leaves in solution most of the culprit gases, including butane and propane.

    Even the industry itself says conditioning would not make Bakken crude meaningfully safer for transportation, though it would make the state’s crude more consistent from one well to another.
    The only solution for safety is STABILIZATION, which evaporates and re-liquefies nearly all of the petroleum gases for separate delivery to refiners. Stabilization is voluntarily and uniformly practiced in the Eagle Ford formation in Texas…”–Railway Age

    And, last week: “…it is becoming self-evident to many outside of the oil business that the nuisance of exploding cargo will not be solved before crude is DE-WEAPONIZED at the well site by cooking off contaminating volatile gases (stabilization).”– Railway Age
