Up to 16% of hydraulically fractured oil and gas wells spill liquids every year, according to new research from US scientists. They found that there had been 6,600 releases from these fracked wells over a ten-year period in four states. The biggest problems were reported in oil-rich North Dakota where 67% of the spills were recorded. The largest spill recorded involved 100,000 litres of fluid with most related to storing and moving liquids.

[...] A [previous] study carried out by the US Environment Protection Agency on fracking in eight states between 2006 and 2012 concluded that 457 spills had occurred. But this new study, while limited to just four states with adequate data, suggests the level of spills is much higher. The researchers found 6,648 spills between 2005 and 2014.

"The EPA just looked at spills from the hydraulic fracturing process itself which is just a few days to a few weeks," lead author Dr Lauren Patterson from Duke University told BBC News. "We're looking at spills at unconventional wells from the time of the drilling through production which could be decades."
