Just wondering.. Sooo.. When does the siphoning stop? How long before the oil runs out?? Would they just keep siphoning until they can build another structure of some sort? Hmmm.
Until the well is shut in. That will happen when they are able to put another preventer on the wellhead, either before or after the relief wells are finished.
Depending on what the determination is as to the stability of the wellbore, they will either P&A it, or drill out the cement in the production casing and complete the well. Either way, I suspect that they are going to have to remove the original BOP at some point. That'll be fun.
