unlock huge reserves of natural gas in the Marcellus Shale, a geologic formation deep underground beneath Pennsylvania, New York, West Virginia and Ohio said to contain enough natural gas to supply the East Coast for up to 50 years.
Lord Browne told HARDtalk's Stephen Sackur of the
huge gas
reserves unlocked by fracking within the USA, saying it now represents 30 % of American gas production.
