Fracing, or hydrofracturing, is a natural gas extraction technique by which a liquid solution (primarily made up of water) is pumped into the ground at high pressures to fracture rock formations. Fracturing the rock releases gas that is trapped inside the rock formation. The geological areas where natural gas is found, and thus where a majority of fracing occurs, is in shale.
By the way, folks in the oil and gas industry call it “fracing”. The mainstream media somehow started adding a “k”, but the correct term is still “fracing” (i.e., there is no “k” in hydraulic fracturing)
Fracing is actually an old technique and has been used for many decades. Once fracing was combined with horizontal drilling, however, oil and gas companies found they could extract far more natural gas, more efficiently, than before.
