Have you ever talked to anyone about fracking? Unless they’ve done their research or are a part of the industry, chances are they do not really understand what it is. This can cause them to believe a number of the myths out there regarding this type of operation. It’s important to educate the misinformed about what fracking really is and how it works. Let’s cut it down to plain and easily understandable terms so you can let others know, in a nutshell, exactly what fracking means.
First, the oil and gas company will drill a hole down into the shale where there is typically a large amount of gas. Often, the layer of shale is thousands of feet below the surface of the earth, and it can take weeks to drill that deep. The company will then place a steel case into the hole as a means to prevent any potential contamination to the groundwater that’s nearby.
Once the drill reaches the correct level, it will turn and then start drilling horizontally. Again, this is a slow process, and the company may need to drill for as much as a mile into the rock. At that point, they will lower a perforating gun into the well. This features explosive charges that will put small holes into the casing that’s in the shale layer.
The company then places a mixture composed of water, sand, and chemicals into the well. They pump this through the well at a very high pressure, and this causes the mixture to go through those small holes that are now in the casing. This causes the fracturing of the shale. The sand will hold the cracks open while the chemicals aid the natural gas in seeping out of the ground and into the pipe.
During the next stage, the chemicals and the water will flow back out of the pipe and be treated or disposed of. The natural gas will then close out of the rock and out of the well. It eventually goes into a pipeline where it ships to customers. One of these wells can produce natural gas for decades, making it a very effective source for getting plenty of gas. It’s easy to see why this form of drilling has become so popular in the United States, and why it is helping to provide the country with a surplus of fuel.
