Two drilling techniques are used to produce shale gas. Horizontal drilling is used to supply higher access to the gas trapped deep in the production. Initially, a well is drilled to the targeted rock development. At the desired depth, the drill bit relies on bore a At the desired depth, the drill bit relies on bore a well that stretches through the tank horizontally, exposing the well to more of the producing shale. Hydraulic fracturing (frequently called "fracking" or "hydrofracking") is a process where chemicals, water, and sand are pumped into the well to unlock the hydrocarbons trapped in shale developments by opening fractures (fractures) in the rock and enabling gas to flow from the shale into the well. When used in conjunction with horizontal drilling, hydraulic fracturing enables gas manufacturers to extract shale gas at the sensible expense. Without these techniques, gas does not flow to the well rapidly, and commercial quantities can not be produced from shale.
