How much oil is in the Gulf of Mexico BP well?

There is ACTUALLY a formula for that!!!  

You take the 200 million gallons per day that are leaking and mulitply that by the expended days it will last and we have the EXACT F

URES!

OOOOPS/day X (forever) = death

Sorry ... but before we can find that answer the entire pooipulation of the World will come to an end so the answer is tragically INSIGNIFICANT!  

This is GREAT!  While Halliburton is figuring out how to kill us off, Mother Nature is planning her "comeback" after a total Planetary Make-over (more sheer ddeath to the population of the world), and at the same time our ascendancy is driving everyone nuts, suicidal, or homicidal.

I'm going back to bed ... Wake me uP when you get this place FIXED!

Oil is not really "in" wells, it is in reservoirs underground, and wells tap into those reservoirs. This well could probably flow for a long long time if uncapped.  I'm not sure if BP has made public the size of this field, but a billion barrels might be a typical value, and there are 42 gallons of oil in a barrel, so that's a lot of gallons.  The flow will decrease with time, but probably not significantly in the short term.
