I've been hearing a lot about the fracking boom lately. What exactly is fracking?

Fracking is a process of drilling and fracturing rock formations to release oil or natural gas. It involves injecting a high-pressure mixture of water, sand, and chemicals into the rock formation to break it up and release the gas or oil. The process can be used to extract oil and gas from shale rock formations, which are often found in low-permeability rock layers.
