Another Marcellus Well Explosion - this time West Virginia

One thing we should know by now: natural gas explodes, whether it's bubbling up through an ocean drilling rig or a well drilled into Marcellus shale. Yesterday a crew drilling a natural gas well through an abandoned coal mine near Morgantown, West Virginia hit a pocket of methane gas that triggered an explosion, burning seven workers. According to AP reports, the explosion happened about 1:30 a.m. in a rural area outside Moundsville, about 55 miles southwest of Pittsburgh. A column of fire shot at least 70 feet high, but the flames fell to 40 feet within hours. Gas continued to burn late Monday afternoon. Read more here.
