BP reported this afternoon that the undersea MC252 well remains shut-in with no oil flowing into the Gulf. The well integrity test is ongoing with active monitoring as the reponse team assesses the effect of the closure of the 3-ram capping stack.

The pressure continues to rise and is currently above 6,700 psi (462 bar). A very low pressure reading would be indicative of oil being released somewhere in the well bore out into the formation—an undesirable outcome.

Subsequent to the conclusion of the integrity test, the team will likely make another seismic run over the area to take a look at the sea floor and do sensor testing into the formation to see if there are any areas where pockets of oil may have formed as a result of being forced out of the wellbore.
