Sorry are you oilfield? That makes no sense. How would the failure of the cap effect the relief well at 13,000', and if somehow it did why could you not pump a cement plug and re drill the last few feet?
Yes I am.
I am not talking about the cap failing, I am talking about the well itself failing when the pressure from being capped raises the wellbore pressures.
That is what is being tested and examined right now - is there anywhere downhole that can’t handle the pressure that is going to happen when the flow of the hydrocarbons is stopped.
