BP Starts To Plug Oil Leak
Five weeks after an oil rig explosion, BP has now started to clog the huge oil leak which is still spewing into the Gulf of Mexico.
The company is attempting what is known as a “top kill” by pumping heavy fluids into the well to push the up-coming oil pressure down, and then using cement to plug the well.
But the procedure is a tricky process that could take up to 24 hours and the probability of success is between 60% and 70%.
If this fails, US President Barack Obama’s government may have no choice but to take charge of the response to what is considered as the worst oil spill in US history.
BP has estimated that about 5,000 barrels (795,000 litres) have been leaking every day, but some scientists have given estimates of up to 20 times more.
At least six million gallons of crude have spewed into the Gulf since April 20, when the explosion on the BP Deepwater Horizon rig sank the drilling platform, killing 11 workers.
