‘Top kill’ to stop Gulf oil spill in ‘very critical’ stage

‘Top kill’ to stop Gulf oil spill in ‘very critical’ stage thumbnail

With the “top kill” timeline stretching on amid what one US official calls a “very critical” period, President Obama said Friday he will send reinforcements to the Gulf Coast within 24 hours to help deal with the massive BP oil spill.

BP is already drilling two relief wells, the first of which would not be ready until August. If the top kill fails, the company will try again try to put a cofferdam over the well to collect the oil. A similar plan failed earlier this month when methane crystals built up, clogging the contraption. Another option is to place a working blowout preventer on top of the malfunctioned one. Both those methods are risky because they will require technicians to cut away part of the pipe that leads to the failed blowout preventer, which could release a larger plume of oil.
