    is you all are not even on the EIA shale play map as of May 2011. Are the Triassic basins in eastern NA targets for fracking? We live near the Newark basin, which does black shales & mudstones. Never heard any talk of fracking here, though. Maybe it's coming?

    •  Black shales & mudstones could contain gas (3+ / 0-)

      The Triassic basins are like today's African rift valleys or the Salton trough in California. The Deep River basin in NC contains coal that helped the south fight the Civil war. The coal mines here had repeated accidents caused by gas and ground water problems.

      So...we don't know that much about what's at depth in the basins.

        the Newark Basin (I believe it and your basin were formed at the same time  - ca 230 mya?) has been cored pretty thoroughly afaik. I've seen the cores - the color changes are remarkable. We were looking for sources of arsenic. Some groundwaters here are contaminated with naturally occurring As.

        Have they done prelim work to see how much gas fracking would yield?

        Do you know how much potentially gas-yielding material there is in the basin?

        I ask because iirc Newark basin is mostly reddish rocks, not grey/black ones. I would assume the red rocks will not yield nat gas.

        thanks

        and sorry to hear this is going on.

        •  The red rocks are oxidized. Gas is unlikely. (1+ / 0-)

          There's a dark unit called the Cumnock formation that's coal and gas bearing in central NC. The red units above it don't generally bear gas unless they trapped it coming up from below.

          •  we have a dark formation - the Lockatong (0+ / 0-)

            however, there are dark layers through the whole thing - 20,000 ft or so.

            they found the timing of the color changes was related to milankovich-type cycles - it was driven by global climate change.

    •  It's exploratory. (0+ / 0-)

      There's shale layers in most of the United States, they don't bother to put them on the maps generally unless someone's achieved at least something beyond hydrocarbon shows drilling through.

      •  In NC they mined coal for many years (1+ / 0-)

        and have completed seismic exploration and drilled multiple exploratory wells.

        We know there's gas near Cumnock and Sanford, NC.

        However, the rest of the Mesozoic basins are a ?
