What you see right now is the two lines they connected to the top kill valves on the BOP.
They are isolated from the well head by the two small ram valves. They have to go through an integrity check list.
They will cycle each ram in the bop and make note of pressure changes. That will give them an idea of how much restriction each one will give, in its
degraded state. That will tell them if there is enough restriction to actually push the oil back.
They will do some preliminary mud pumps. Up the volume each step to see how much mud it takes to reach a balance point, to hold the oil at bay.
Then they will know how much is going down the hole when the up the level from balance point.
