July 10 - A Better Cap
In a procedure that would take several days, BP removed the well cap that was put in place on June 3 to replace it with a new one with the potential to completely stop the flow from the well. The new cap has some of the same types of components as the blowout preventer. Once installed, engineers will take pressure readings for up to two days. If the pressure is at an anticipated level, the cap could remain closed, ending the gusher.
