Shale oil boom is not that rosy

Beholden to the surging US shale oil production, Brent crude oil price tumbled to below $73/barrel today. There is always a downside for this boom: for every 1 barrel of shale oil produced, 1.4 barrels of toxic brine is generated. Scores of inferno and serious oil spillage in North Dakota in the last two years. Shale oil production needs yet to be proved as a sustainable shot-in-the-arm for US economic development.
