Senior Chief Petty Officer Mike O’Berry said remote controlled submarines have been unable to shut the valves on equipment at the wellhead on the sea floor, but it appears the flow of oil from subsurface reservoirs has stopped on its own.  Houston Chronicle

It’s surprising that the flow would stop on its own.  They were reported to have just set production casing, so the well was fully cased.  Perhaps the flow emanated from the production casing annulus, and sediments bridged or plugged the annulus?  It will be interesting to see what the next steps are.  An attempt to reconnect to the well with a new rig and riser would seem unlikely unless they can confirm that the BOPE is functioning properly.  It seems likely that the relief well will continue.
