Natural Gas
The Conasauga Shale is a shale gas reservoir, like the Barnett Shale in Texas. The shale is very hard, and until technological advancements as have been honed in the exploration and drilling of the Barnett Shale, it was too costly to extract. The Conasauga Shale is hydro-sensitive as the shale will absorb water, swell and thereby slow the flow of gas. Therefore, successful drilling of the Conasauga involves utilizing techniques minimizing water use and subsequent flow into the open-hole drilling techniques. Casing is normally used only until penetration into the Conasauga and then left open-hole so that multiple gas layers within the hole may flow to the borehole.

Famous quotes containing the words natural and/or gas:
“PLAYING SHOULD BE FUN! In our great eagerness to teach our children we studiously look for “educational” toys, games with built-in lessons, books with a “message.” Often these “tools” are less interesting and stimulating than the child’s natural curiosity and playfulness. Play is by its very nature educational. And it should be pleasurable. When the fun goes out of play, most often so does the learning.”
—Joanne E. Oppenheim (20th century)
“Man moves in all modes, by legs of horses, by wings of winds, by steam, by gas of balloon, by electricity, and stands on tiptoe threatening to hunt the eagle in his own element.”
—Ralph Waldo Emerson (1803–1882)
