Explained: Fracking for Oil
The idea for fracking dates back to 1862 and has been credited to Edward A. L. Roberts. During the earlier days, explosives were used for shattering the surrounding rocks in the oil well but in the 1940s, explosives were replaced with high-pressure blasts of liquids, and so “hydraulic” fracking became the standard in the oil and gas industry. It wasn’t until the 21st century that fracking saw a massive boom and that was because of two innovations, first, the use of a certain type of fracturing fluid: slickwater, a mix of water, sand, and chemicals to make the fluid less viscous and second, horizontal drilling, a technique that increases the productive potential of each well.
