A study commissioned by Plains Exploration & Production Co. concluded hydraulic fracturing of two test wells at Inglewood oil field in Los Angeles County, Calif., indicated no detectable evidence that it might induce earthquakes or have negative consequences on groundwater quality.
California is expected to release a draft of their new fracing rules soon.
The fracing study was part of a 2011 settlement stemming from a lawsuit filed in 2008 against Los Angeles County and Plains Exploration concerning land use. Standard Oil discovered Inglewood field near Culver City in 1924. Plains Exploration has operated the field since December 2002. Conventional fracing has been done at the field.
