I'm not the sharpest tool in the shed, but I am a driller. Although, the deepest hole that I ever drilled was 300 feet, I have an idea. I hope that I don't embarrass myself. I suggest dropping a large diameter (4' to 10') casing to the sea floor, over top of the well. I know that it will take a long time to weld the casing together, not to mention finding a mile of it, but hear me out. By the way, my idea can't be all that much worse than using golf balls and rubber to plug it. The weight of the casing will be enormous, so when the weight of the casing has reached 1/2 the capacity of the crane lowering it, start adding air bags to offset the weight. Once the casing hits bottom, use the submersibles to start releasing the airbags. Hopefully the weight of the casing will make it sink deep into the ocean floor and oil will be diverted to the surface. Upper airbags can be left to help keep the casing upright and relatively stable. The oil could then be loaded into a barge or ship and removed. Tremie pipes, or gro...
