Can oil leaks come about naturally?

1st August 2011

Asked by: ROBERT CRADDOCK, BY EMAIL

Yes. Weathering and tectonic upheavals can rupture underground oil reservoirs and allow oil to reach the surface. The La Brea tar pits near Los Angeles are one example and off the coast of Santa Barbara in California there’s an oil field that’s been leaking 20-25 tonnes of oil every day for the last several hundred thousand years.
