The image above shows a schematic of the Bakken Formation,, which lies along the U.S.-Canadian border, beneath the prairies of North Dakota and Montana. It is considered to be the largest reserve of oil in the lower 48 U.S. states.

North Dakota separates property ownership of land surface from ‘bottomland’, what lies beneath the surface. This has become a lucrative form of land ownership over the past few years as new fracking projects have turned vast tracts of prairie and farmland into a new oil heartland, sometimes over the vehement objections of farmers who bought land without realizing they didn’t really own more than a plow’s depth of dirt.

And now that heartland has its first major oil spill, which already counts as one of the largest onshore spills in U.S. history. 20,600 barrels – equivalent to 865,200 gallons (3.2 million liters) – were belatedly discovered bubbling up from a faulty ageing pipeline on an area the size of 7 football fields within a remote wheat farm.

The pipeline company, Tesoro Logistics, has thus far succeeded in cleaning up around 5% of the spill. The company claims that neither surface nor groundwater was affected in any way, nor will there be any adverse effect on the environment. In any case, according to the farmer who owns the land, the fields will be unusable as farmland for the foreseeable future.

  1. You can’t just leave that story there!! What is the farmer and community doing? Is Tesoro a US company? Of course I can look that up. But I want to know more.

    • Hi Molly! Well, the story gets left there because for the moment there isn’t much more information on what is being done. Tesoro has sent in a clean-up operation, which is essentially a lot of digging machines with vacuum hoses, and they are removing the contaminated soil (but so far, only a fraction of the oil has been removed). And yes, Tesoro is a US company, formed in 2011 as a Delaware holding company. Almost all the senior officers are very established Texas-based oil professionals.
      I’ll update the story when I get more news.
