- Fracking is a term used for hydraulic fracturing, which is the process of creating fractures in rocks and rock formations by injecting specialized fluid into cracks to force them to open further. The larger fissures allow more oil and gas to flow out of the formations and into the wellbore, from where they can be easily extracted.
- Fracking has resulted in many oil and gas wells attaining a state of economic viability due to the level of extraction that can be reached, and has allowed drilling firms access to previously difficult-to-reach sources of oil and gas.
