If they pumped in 30,000 barrels of mud, and the drilled chamber only needs about 1300 barrels of mud to fill up, where did the other 28,700+ barrels of mud go in the last day? Did it leak out the riser?
As a casual observer this is indeed the question. They have lost 90% of what they are pumping into the well, where did it go and how is it getting out?
The Oil Drum has some interesting theories that there are leaks around the outside/layers of below ground casing due to insufficient/inadequate cement job.
Take this from a novice, but if true, IMHO we have a long way to go to fix this thing.
Addicting ... :-)
