The MC252 well has been shut-in since July 15. Following the completion of cementing operations on the well on August 5, pressure testing was performed which indicated there is an effective cement plug in the casing.
A number of operations have been successfully completed to allow the DDIII drilling rig to be in a position to begin drilling the relief well to intercept the MC 252 well annulus.
