A typical oil well is built straight down and pumps out all of the oil and natural gas that is deep down in the earth. But after continual use, these oil wells can start coming up dry. So fracking involves angling the drill horizontally into the rock layer and then blasting water at high pressures (this is why its called hydraulic) to release natural gas.
