The relief wells, at least in this case, are not going to be used like that. They are going to be used to pump heavy mud into the base of the main well until the column of mud overcomes the pressure and stops the flow. Then the well will be cemented in.
.
That was my understanding as well. They were going to use the relief well to pump in mud/concrete.
Then they might come back later after new valves are installed and recover that well and drill through the mud/concrete cap.
now... with that said, I'm not sure why they just couldn't start recovering oil from the relief well, but I assume that some of it would/could still bypass and leak. (just an assumption on my part). So I'm guessing that's why they are capping first? anyone know for sure?
