The current total estimates range from 377,000 tons to 832,000 tons of oil.
Safety and prevention should be the primary focus for correcting oil leaks from deepwater oil rigs. There should also be mitigation systems that are tested and predeployed as soon as possible in case there are future problems with any of the thousands of deepwater oil rigs.
Joseph Friedlander had a detailed suggestion for dealing with the current problem.
Nextbigfuture has suggested energy plans for shifting away from oil and coal as soon as possible.
There will be an update shortly. Fairly rapid impact can be achieved by aeromodding and economically retrofitting existing cars and trucks to double gas mileage. The largest and most heavily used container ships can be converted to nuclear power propulsion, which are currently used by hundreds of military naval ships and submarines.
This could mean it is larger than the Ixtoc deepwater oil spill of 1979. Ixtoc I was an exploratory oil well being drilled by the semi-submersible drilling rig Sedco 135-F in the Bay of Campeche of the Gulf of Mexico, about 100 km (62 mi) northwest of Ciudad del Carmen, Campeche in waters 50 m (160 ft) deep. On 3 June 1979, the well suffered a blowout resulting in the fourth largest oil spill and the third largest accidental spill in history. The Ixtox leaked about 3 million barrels or about 480,000 tons. Mexico’s government-owned oil company Pemex (Petróleos Mexicanos) was drilling a 3 km (1.9 mi) deep oil well when the drilling rig Sedco 135F lost drilling mud circulation.
