BP has said that using materials such as golf balls and tyres could help stem the oil flow at the ruptured Deepwater Horizon well in the Gulf of Mexico.
BP chief operating officer Doug Suttles said it may be possible to stem the flow by blocking the well’s failed blowout preventer with such “debris”.
BP revealed that it is spending $10m per day and has already spent $350m towards the clean-up operation.
At least 5,000 barrels of oil a day have been leaking unchecked into the Gulf since the Deepwater Horizon rig exploded on 20 April, rupturing the well and resulting in 11 missing crew, presumed dead.
The growing oil slick has so far covered about 5,200km² and is threatening an environmental disaster along the US coastline.
Independent agency Galileo Group said it will be collecting airborne hyperspectral imaging data from areas of the Gulf of Mexico shoreline affected by the oil spill, reports the BBC.
As the oil reaches landfall and begins to interact with wetlands and sensitive environmental areas, Galileo’s airborne hyperspectral technology is designed to track and pinpoint the spill and can greatly assist in the clean-up effort.
