Gas can either be retained in the shale as free gas in fractures and pores or adsorbed on organic matter or clay particles. Up to 90% of shale gas is composed of methane, and the remaining proportion is made up of carbon dioxide, oxygen, nitrogen, hydrogen sulphide and small amounts of light hydrocarbons.

In order to extract natural gas from low permeability shale, fracturing fluids are pumped into a wellbore, a process which increases pressure underground, causes shale layers to crack, and allows the gas contained within the shale to escape. Water is the most accessible and affordable liquid so it is the primary component of fracking fluid.

The resulting fracture networks within shale are typically kept open with proppants to encourage the gas flow from shale to the producing well thus improving gas recovery [6,7]. The fracking fluid is generally composed of water (~99.5%), proppants and a mixture of chemical additives that vary depending on the characteristics of shale reservoir [8,9].

The charge shoots small holes through the casing, cement, and a short distance into the shale. Stage 2 - Fracturing Shale is compressed and must be fractured to extract natural gas. Fracking fluid is sent into the casing under high pressure and out of the perfs into the rock.
