Question

What extraction process involves setting off explosive charges, to create cracks deep in rock and then pumping a mixture of water, sand and chemicals into the cracks?

Answer 1

Answer:

Hydraulic Fracturing is also referred as Fracking. In this process, rock is fractured with the help of pressurized liquid. It involves injecting highly pressure fracking fluid, which is primarily water. It also contains sand or other suspended particles. Fracking fluid cracks down deep-rock formations, resulting in free flow of  natural gas, petroleum, and brine.
