One of the major concerns with fracking for natural gas is the amount of water used during the fracking process. Millions of gallons of water, sand and chemicals are pumped into the ground to extract natural gas by fracturing the rock formations. The fractures allow the oil and gas to flow naturally into the wells.
With the development of Waterless fracking (LPG fracking), will fracking be as much of a concern? Waterless fracking still fractures the rock formations; however, the process no longer calls for millions of gallons of water. How does it work? Waterless fracking replaces water and chemicals with propane. The propane is a thick gel mix with sand and then shot into the ground similar to traditional fracking techniques. The thick gel turns into vapor while still underground and returns to the surface in a recoverable form.
Many states are testing waterless fracking techniques, including Ohio and New York. New York currently has a moratorium on fracking; however, if waterless fracking techniques prove to be successful, the moratorium could be released.
Fracking Science believes that new technology could be a game changer.
