The process causes the fracturing of rocks by use of a pressurized liquid, the so-called fracking fluid (Figure 1). This fluid is composed primarily of water and sand or other proppants as well as thickening agents. The pressurised injection into the wellbore creates cracks in the rock formations containing the oil or gas of interest.
