Lighting a New Path
Flares from newly completed natural gas wells paint an arresting image in the Pennsylvania sky.
But the fiery scene above ground—a controlled test burn-off of initial gas that takes place at some wells for several days—is not as dramatic as what is happening a mile beneath the surface. Producers are using high-volume hydraulic fracturing and horizontal drilling to unlock a natural gas resource that geologists have known about for 75 years.

The Science of Shale Gas
By combining and super-charging old oil field technologies, U.S. energy industry innovators unlocked the natural gas found in deep shale rock—paving the way for a rush on the huge Marcellus shale formation that underlies Pennsylvania.
