Energy in Depth, a group representing oil and natural gas producers, has sent a letter to the Academy of Motion Picture Arts and Sciences arguing that "Gasland," ...should be ineligible for best documentary feature because it contains inaccuracies...

...In one dramatic scene highlighted in the trailer for "Gasland," a man in Fort Lupton, Colo., lights his tap water on fire, and the implication is that fracking contaminated his well with methane. Challenging the scene, Energy in Depth pointed to a Colorado Oil and Gas Conservation Commission investigation that found the methane in Fort Lupton was "biogenic" — that is, naturally occurring.

According to Anthony Ingraffea, a professor of engineering at Cornell University...there's no doubt that the methane in the man's tap came from nature...In his opinion, the flammable gas probably was released by fracking
