BP completes kill operations on Gulf relief well

‘We can finally announce that the Macondo 252 well is effectively dead,’ said Admiral Thad Allen, US national incident commander.

The MC252 well has been shut-in since 15 July and cementing operations in August, following the static kill, provided a cement plug in the well’s casing.

The relief well drilled by the DDIII drilling rig intercepted the annulus of the MC252 well on September 15, followed by pumping of cement into the annulus on 17 September.

BP, a US government scientific team and the national incident commander have now concluded that these operations have also sealed the annulus of the MC252 well.

BP says it will now abandon the MC252 well, a procedure that includes removing portions of the casing and setting cement plugs. A similar plugging and abandonment of both relief wells will also occur.

BP US chairman and president Lamar McKay said: ‘BP will continue sharing what we have learned in an effort to prevent a tragedy such as this from ever being repeated. We also believe that the industry will gain important insights on how to be better prepared to respond to any future incidents.’
