GRAND CANE, La. — Two miles beneath northwest Louisiana's patchwork quilt of forests, cotton fields and pastures, dozens of drill bits are grinding their way toward what may be the nation's energy future.

The region around Shreveport has known oil and gas exploration for decades, but it's now buzzing anew as companies try to capitalize on one simple fact — locked into cement-like shale formations thousands of feet underground are potentially huge quantities of natural gas.


The gas found in the area's Haynesville shale and in other shale formations throughout the country has changed the nation's energy outlook in just a few short years.

Some see abundant North American natural gas as the gateway to reduced dependence on foreign oil and a bridge toward carbon-free energy sources since gas is the lowest-emission fossil fuel.

Others say the surge in next-generation gas production isn't paying off as promised and threatens local water supplies.

Some even see it as another speculative bubble, driven by hype that will never deliver the fuel it promises.
