Roughly 13% of California oil and gas wells have been fracked at least once. Overall, permitted fracking operations accounted for just 2% of statewide oil production in 2021.
Environmental Protection Agency illustration of the water cycle of hydraulic fracturing. Fracking in the United States began in 1949. [1] According to the Department of Energy (DOE), by 2013 at least two million oil and gas wells in the US had been hydraulically fractured, and that of new wells being drilled, up to 95% are hydraulically fractured.
California water officials backed a bill to impose restrictions on where wells can be drilled, seeking to protect drinking water sources. Lawmakers rejected it.
Gov. Gavin Newsom continues to rack up a laundry list of provocations against the state’s oil industry, but the administration’s own oil and gas regulator approved ten new permits for new ...
Hydraulic fracturing uses between 1.2 and 3.5 million US gallons (4,500 and 13,200 m 3) of water per well, with large projects using up to 5 million US gallons (19,000 m 3). Additional water is used when wells are refractured. [28] [29] An average well requires 3 to 8 million US gallons (11,000 to 30,000 m 3) of water over its lifetime.

As of 2022 there are approximately 180,000 Class II wells injecting over 2 billion gallons of fluids daily. Most Class II wells are used for enhanced oil recovery, such as waterfloods. About 20 percent of Class II wells are used in waste disposal, to dispose of produced water, usually brine, into deep formations below the base of fresh water. [21]
