Subsea Source Control
Operations conducted bottoms up circulation, which returned the contents of the well’s annulus to the rig for evaluation. Testing of the drilling mud recovered from the well indicated that no hydrocarbons or cement were present at the intersect point. Therefore, no annulus kill is necessary, and the annulus cementing will proceed as planned. It is expected that the MC252 well will be completely sealed on Saturday.
Once cementing operations are complete, the DD3 will begin standard plugging and abandonment procedures for the relief well.
The Development Driller II continues its work to gather additional data from the MC252 well and try to determine the location of the drill pipe that was originally in the well at the time of the accident. Subsequently plug and abandonment activities will commence in accordance with the approved procedure.
