【Original】BP finally seals leaking Gulf of Mexico oil well
|
  The ruptured well that has spewed millions of barrels of oil into the Gulf of Mexico has finally been sealed, US officials say. A pressure test showed a cement plug put in place by BP to permanently "kill" the well was holding. President Obama hailed the news, vowing to continue to help those affected. The worst offshore oil spill in US history began after the Deepwater Horizon rig blew up on 20 April, killing 11 workers and later sinking. 'Important milestone' The top US federal official overseeing the disaster, Coast Guard Adm Thad Allen, said on Sunday that the well was now "effectively dead". "Additional regulatory steps will be undertaken but we can now state definitively that the Macondo Well poses no continuing threat to the Gulf of Mexico," Adm Allen said. A temporary cap had sealed the flow on 15 July while a relief well was dug. That well finally linked up with the ruptured well on Thursday, allowing workers to start pumping in the cement, removing the need for the cap and creating the permanent "kill". The disaster has brought an environmental nightmare to hundreds of miles of US coast. It led to BP chief executive Tony Hayward standing down and the imposition of a moratorium on deepwater offshore drilling. In a statement, President Obama hailed Sunday's "important milestone" and thanked all those who had "worked around the clock to respond to this crisis and ultimately complete this challenging but critical step to ensure that the well has stopped leaking forever".  The impact on the economy and wildlife has yet to be fully assessed |
