Hydraulic fracturing, also commonly known as “fracking”, is a method often used nowadays to extract natural gas. The process starts when a steel pipe casing is inserted into the drilled well bore. Tiny holes are made in the pipe in order to let the fracturing fluid flow into the zones which contain oil or gas. Eventually, these zones will fracture due to the pressure from the overflowing fluid. Once the fractures are formed, the fluid halts and flows back to the surface. Remnants from fluid such as sand are then left behind, holding open the fractures. Another way to form these fractures is to inject gases such as nitrogen. Acidizing sometimes occur while fracturing where hydrochloric acid is pumped inside to …show more content…
