It’s not the oil pumped in the Texas desert or offshore in the Gulf of Mexico. It wasn’t the bubbling crude Jed Clampett found in his swamp in the 1960s television show “The Beverly Hillbillies.”
The oil that spilled last year from the Enbridge Inc. pipeline in Marshall, Michigan was a thicker crude oil, containing dilutants and heavy metals.
In its natural state, it’s almost solid and is mixed with a dilutant to help transport it through 1,900 miles of pipeline that runs from Western Canada to the United States.
It’s known as heavy crude oil, tar sands oil or diluted bitumen.
And some of the heavier parts of the oil are on the bottom of the Kalamazoo River. MORE
