A White House adviser said Wednesday that the 'vast majority' of the Gulf oil spill is gone. But a summary of the report she cited leaves some questions unanswered.
'Static kill' worked. Some 2,000 barrels of heavy drilling mud are now keeping the oil at bay until the relief well can finish the job in mid-August, killing the Gulf oil spill gusher for good.
Industry and environmentalist groups agreed Tuesday on tougher efficiency standards for home appliances that, over the next 30 years, could save enough energy to power 40 percent of American homes for a year.
Static kill, which began Tuesday, will attempt to force the oil back into its reservoir. But BP won't know if static kill worked – and the Gulf oil spill is over – until it finishes its relief well.
With its $5 million investment in the Indiana startup Bright Automotive, which plans to build a plug-in hybrid delivery truck, GM potentially gains access to new technology and maybe a new product.
A new estimate suggests that the Gulf oil spill blowout gushed 4.9 million barrels of oil before BP capped it, making it the largest accidental oil spill in history.
The EPA issued a report Monday that suggests the dispersant used by BP in the Gulf oil spill, Corexit, doesn't form a more toxic stew when mixed with oil. The dispersant was also no more toxic than seven other alternatives, the study concluded.
The 2010 Gulf of Mexico 'dead zone' of oxygen-deprived water – roughly the size of Massachusetts – is patchy and more spread out than usual.
Signs of recovery from the Gulf oil spill are already appearing, but scientists caution that many unknowns exist – including the effect of millions of gallons of oil dispersants.
BP is set to plug the well in the Gulf oil spill permanently. Next week, it will begin 'static kill.' A week after that finishes, it will follow up with 'bottom kill.' Why are both necessary?
Rep. Edward Markey says documents released by his office Saturday cast doubt on BP's assertion that it used 1.8 million gallons of the toxic and controversial oil dispersant, Corexit.
Federal regulators had issued safety warnings about the condition of the pipeline in the Michigan oil spill that leaked nearly 1 million gallons of oil into the Kalamazoo River this week.
The Gulf oil spill drama is about to reach its climax: the killing of the Macondo well. But a setback Friday will delay the start of the operation until Tuesday – and shows that uncertainties still loom.
