Fraccing

I have also heard from geologists who say they spell it fraccing, and one who says it's fracting with a silent t.

Fraccing is the process of creating cracks in underground coal seams to increase the flow and recovery of gas or oil out of a well.

The industry argues that this is highly unlikely, as the fraccing takes place a mile or more below drinking water aquifers and is separated from them by thick layers of impermeable rock. Moreover, the industry has a great deal of experience with fraccing. More than a million wells have been fracced in the United States since the first frac job six decades ago.

Fraccing fluids contain proppants that forced into the natural fractures of fissures of the rock under pressure.
