Exclusive - California used 70 million gallons of water in fracking in 2014



    SAN FRANCISCO (Reuters) - California oil producers used 214 acre-feet of water, equivalent to nearly 70 million gallons, in the process of fracking for oil and gas in the state last year, less than previously thought, state officials told Reuters on Thursday.

    Hydraulic fracturing, or fracking, occurs when water and some chemicals are injected underground at high pressure to break up rock and release oil and gas into wells.
