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.
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]
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). [171] Additional water is used when wells are refractured. [75] [172] An average well requires 3 to 8 million US gallons (11,000 to 30,000 m 3) of water over its lifetime. [67]
Overall, researchers estimated that 32% of the 29,567 domestic wells analyzed are at risk under the plans that agencies submitted, as well as 21% of the 5,259 wells that supply public water ...

The bulk of the wells drying up in Central California, so far, are in the Fresno and Madera areas, according to an analysis. Extreme heat straining water wells in Fresno, Madera counties. ‘Not a ...
