BP is to remove the blow-out preventer directly above the well on the sea bed at 5000 feet depth to connect a containment cap that is currently on-site. BP is expecting to take 3 days to finish the procedure.
Undersea collection system
BP said that the method has never been attempted at these depth, therefore the two relief wells are being drilled simultaneously with the containment cap.
In this situation, the containment cap on to the lower marine riser package (LMRP) is only a temporarily fix due to the oil being siphoned into a mother ship above. Hence the two relief wells that are being drilled at a 90 degree angle on the right and left side of the well will be attempting to intersect with the pipe under the LMRP to intercept it and shut it off are the permanent fix to the problem.
