at that point, they'll begin to pump mud into the choke line, and the horizon blowout preventer. it will start at one barrel per minute and move that up to two barrels her minute. there's going to be a very low rate of injection into the well because we don't need to do it in a higher rate as we did with the top kill because there's pressure back on the well with the capping stack. we don't know exactly how much mud will be pumped in. it will depend on the condition of the well itself. there are three areas that need to be filled, the drill pipe, the casing itself and the area outside the casing to make sure neither gas nor hydrocarbons come up through that. we don't know the exact condition of the well. usually there is no way to enter the anulus from the top but if the seals are compromised, it might be possible to put mud into the anulus.
