Hydrocarbons in the deep Earth?

FILE THIS UNDER “THINGS I’D LIKE TO BE TRUE:” Hydrocarbons in the deep Earth? “The oil and gas that fuels our homes and cars started out as living organisms that died, were compressed, and heated under heavy layers of sediments in the Earth’s crust. Scientists have debated for years whether some of these hydrocarbons could also have been created deeper in the Earth and formed without organic matter. Now for the first time, scientists have found that ethane and heavier hydrocarbons can be synthesized under the pressure-temperature conditions of the upper mantle —the layer of Earth under the crust and on top of the core. The research was conducted by scientists at the Carnegie Institution’s Geophysical Laboratory, with colleagues from Russia and Sweden, and is published in the July 26, advanced on-line issue of Nature Geoscience.” Abiotic hydrocarbons is an old theory; it would be nice if it were true.   http://pajamasmedia.com/instapundit/82538/   I suppose the other thing here is that even without this turning out to be true, the reserves of non-conventional hydrocarbons already known, including marine methane hydrates, are vast.   Though they often present great challenges in getting to them.
