As the shale oil output in the United States surges and global demand weakened, the international oil price has plunged from a barrel of 115 U.S. dollars a barrel this year to near-term gains. Opec, the Organization of the Organization of the Petroleum Exporting Countries that controls 40% of global oil output, is resentful on the 10th, saying that oil demand in 2015 is expected to drop to its lowest level in 12 years.
