    Deep Earth hydrocarbon discovery - oil and methane without organic matter
    Posted On: July 26, 2009 - 5:30pm


    Washington, DC—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.

    Methane (CH4) is the main constituent of natural gas, while ethane (C2H6) is used as a petrochemical feedstock. Both of these hydrocarbons, and others associated with fuel, are called saturated hydrocarbons because they have simple, single bonds and are saturated with hydrogen.

    Using a diamond anvil cell and a laser heat source, the scientists first subjected methane to pressures exceeding 20 thousand times the atmospheric pressure at sea level and temperatures ranging from 1,300 F to over 2,240 F. These conditions mimic those found 40 to 95 miles deep inside the Earth.

    The methane reacted and formed ethane, propane, butane, molecular hydrogen, and graphite. The scientists then subjected ethane to the same conditions and it produced methane. The transformations suggest heavier hydrocarbons could exist deep down. The reversibility implies that the synthesis of saturated hydrocarbons is thermodynamically controlled and does not require organic matter.

    The scientists ruled out the possibility that catalysts used as part of the experimental apparatus were at work, but they acknowledge that catalysts could be involved in the deep Earth with its mix of compounds.

    I find this article a little confusing as hydrocarbons are organic matter.

    Organic matter is based on hydrogen and carbon ask Ginger!

    We are nowhere even close to running out of oil.

    We have found and drilled MOST of the easy to find stuff, that being large structural domes. There are significant amounts of oil that are untapped in what are called "stratigraphic traps". These are a bit harder to find, but there are lots of them.

    When I worked in the oil business, my largest discovery was of a stratigraphic trap, formed when a 150 foot thick layer of salt, 10000 feet below the surface, dissolved and the overlying strata collapsed into the sinkhole it created.

    Shell Oil missed that one - their geophysicists dismissed it as a processing anomaly.

    Yes and no. Back in the day it was convenient to make a common sense separation between organic and inorganic matter in chemistry. Today we know that the common sense approach isn't always super accurate.

    Not all hydrocarbons are equal and heavy hydrocarbons are apparently capable of being created through pressure and temperature effects on a completely inorganically produced methane. This is pretty interesting just in own right but obviously may have a lot of implications for what we currently know about "fossil fuels".

    And yet we have over 100 years worth of supply (at current demand) RIGHT HERE that we are not allowed to touch.

    The very definition of oil reserves changes with the economics. In 1980 or so, Venezuela wasn't among the countries considered to have commercially viable oil reserves. Now, they are among the largest. The rising oil prices reached the point required to make getting the crude out of their sand a profitable venture.

    All of this peak-oil bullshit omits little details like this.

    some very strage things going on with oil . . . .
    Stand up for what is right, even if you have to stand alone.

    Sounds like someone is trying to drive up the price of crude oil. We have plenty of oil right here in this country. But personaly I cant wait until we perfect the hydrogen power cell. then the premitives in the middle east can happly go about killing each other and no one will give a shit.

    If we did not have so many dumb shits in DC, we could eliminate the 15% of M.E. oil that we import from them.According to our legislators, all fossil fuels are bad. Not so; natural gas is a clean burning fuel and we have tons of it in the US. Rather than the government support them with tax incentives/subsidizes, these dunces go on wild goose chases with their environmental greenie projects like wind solar and Ethanol. How dumb can you be when you take a food source, cook it using oil to make another energy product. All these alternative energy screw ball ideas are going to jack up the cost of energy. I am beginning to think that is the plan of the madman in the W.H.
