Fracking is essential for the production of natural gas and oil from shale formations, and with advances in fracking technology, it is becoming easier and more accessible to access natural gas.
Whether fracking can continue spreading without major harm to the environment or public health, and whether it promises to reduce greenhouse gas emissions, are questions researchers are still working to answer. Fracking is a process for extracting natural gas from shale layers typically thousands of feet deep. These targeted shales arenât especially permeable, meaning most of the gas is trapped. So drillers blast the rock layers with highly pressurized water containing chemicals that reduce friction between water and rock.
