Experts Try to Change Faulty Perception of Fracking Replacing Water with CO2
Hydraulic fracturing, or fracking, is the process of pumping water, sand, and other chemicals under high pressure into the ground to break apart rock and release the natural gas contained. By 2013, there were over two million oil and gas wells that had been hydraulically fractured in the U.S., according to the Department of Energy (DOE). It's estimated that about 95% of all new wells are drilled under these conditions.
According to British technology website The Register, new research from the University of Virginia led by Andres Clarens is looking at the possibility of replacing water with CO2 at fracking sites. The idea is that CO2 would act as a carbon sequestration, making fracking that much more efficient and sustainable.
