This is a good reality check on the ultimate impact of the messy oil leak. Sooner or later, the ocean and Mother Nature will digest the works. This helps understand why. No comfort if it is your favorite beach but otherwise it will disappear.
When the oil first emerges, it appears that a light fraction is able to separate. This provides the surface show. The rest submarines and slowly loses buoyancy until it is largely broken up or digested. It is unlikely to come ashore and some may infiltrate the sea bottom.
Way more important, is that the relief well is already on the last step right next to the run away and is ready to do the last step. They want to break into the casing. The operating company is 40 for 40 on this type of situation. Once access is achieved, they will push mud down the well to flood the bottom of the run away to kill it.
I suspect this will work.
That complete, surface cleanup can eliminate most of the visible problem while the deeper stuff should steadily dissipate.
That will leave the beach and wetland damage and so far that has been fairly restrained and will respond to basic grunt work with lots of hay.
They will not get everything out there, but this is all subtropics. Mother Nature will eat the rest surprisingly fast. One year sounds fast while five years sounds slow.

The BP Gulf Oil spill ongoing and the possibility of capping operations causing a blowout (an explosion which would release more oil) of 240,000 barrels per day. Here is a consideration of the total volume of the oceans and the total volume of the world's oil.
The total mass of all of the Earth's water is about 1,400,000,000,000,000,000 metric tons (1.5×10^18 short tons) or 1.4×10^21 kg, which is about 0.023 percent of the Earth's total mass. Less than 3 percent is freshwater; the rest is saltwater, mostly in the ocean.
The global economy consumes approximately 30 billion barrels of oil (1.2 trillion
The world consumes approximately 3 CMO (cubic miles of oil or equivalent energy) annually from all sources. There are about 40 years of conventional oil reserves (1300 billion barrels of conventional oil reserves. Exploration could find more oil.
There are maybe 200 years using all the oilsands and oilshale. This varies based on recovery percentages (ie how much of the oil in place you can get economically).
If you mixed it all of the oil into the oceans then you would be looking at about 1 part per million. Which is about 35 times less than the EPA defined safe limit of 35 parts per million limit.
You would not have equal distribution so that is the cause of dead zones and what causes oil to wash up on shore and leave a big mess and why if you can disperse the oil safely then it is less of a problem.
The ocean volumes to the total world oil reserves is a volume and relative size comparison. Oil leaks do not have equal distribution or much mixing. Oil collects on the surface and the surface oil that does evaporate or get collected gets onto the shore.
There is natural seapage of oil into the
A reminder is that the 1979 leak into the
