Drilling & Fracking
“Fracking” wells are drilled thousands of feet into the ground to reach a target oil or gas reservoir. The well then turns horizontally to intersect and remain within the reservoir (e.g. shale layer) for distances that can reach over three miles. A mixture of water, sand, and chemicals are injected into the well at high pressures, and explode out of the well bore to crack open the shale rock, releasing oil and gas. These photos depict oil and gas drilling and fracking infrastructure and buildout in various locations around the US.
