North Dakota Oil Spill

In this Oct. 11, 2013 file photo, cleanup work is seen at the site of an oil pipeline leak and spill beyond an old farmstead on the Steve Jensen farm north of Tioga, N.D. Scientists who helped calculate oil spilled from a broken BP well into the Gulf of Mexico are questioning the methodology used to estimate the amount of crude that recently leaked from a ruptured pipeline into a wheat field in northwestern North Dakota. Tesoro Corp. said it came up with its more than 20,000-barrel spill estimate using ground analysis. But oil spill experts say a more accurate assessment likely would come from calculating how much crude went into the pipeline versus what was supposed come out at its terminus.
