 In spite of its complications,​ hydraulic fracturing is still commonly used today globally because of its propensity to extend the life of aging wells, or make previously unextractable wells extractable. In the United States, there were [[https://​www.fractracker.org/​categories/​by-content/​class-II-injection-wells/​|over 150,000 Class II injection wells]] as of 2016. [[https://​www.epa.gov/​uic/​class-ii-oil-and-gas-related-injection-wells|Class II oil and gas related injection wells]] include disposal wells, which are wells where already contaminated ("​slurry"​) is re-injected back into the ground for permanent disposal; enhanced extraction wells, which are new or old wells where extraction of oil and gas is enhanced by the injection/​fracturing process; and strategic reserve wells (e.g., US strategic oil reserve), where already recovered oil and gas are injected into an underground system for later recovery. In spite of its complications,​ hydraulic fracturing is still commonly used today globally because of its propensity to extend the life of aging wells, or make previously unextractable wells extractable.
