The US government allowed the cap stemming the flow of oil in the Gulf of Mexico to remain closed for another day, as BP fleshed out plans for a possible “static kill” operation.
US disaster response commander Admiral Thad Allen said engineers had found seepage and other anomalies, but said none were “consequential” enough to stop the well integrity test, now in its fifth day.
Despite his optimism, Allen ordered BP to produce a “detailed timeline” by the end of Monday for restarting operations to contain the oil with a fleet of surface vessels if the cap had to be opened again.
The announcement on Thursday that BP had stopped the oil flow completely for the first time since April raised hope among devastated communities along the Gulf Coast that a three-month nightmare may soon be over.
Measuring devices on BP’s cap have given steadily increasing high-pressure readings, which would indicate there are no major leaks in the well bore that stretches an astonishing 2.5 miles (four kilometers) below the seabed.
BP wants to keep the valves on the cap closed continuously until operations to permanently seal the well can begin in less than two weeks time, meaning no more toxic crude would stream into the Gulf.
Allen is more cautious and insists that keeping the cap on until the relief well operation is not a done deal as there are still too many uncertainties to know it has been shut in safely.
Both Allen and BP floated the idea of a new operation to plug the well called the “static kill” — very much like the “top kill” operation that failed almost two months ago.
BP said the idea would be to send down heavy drilling mud as before through the giant blowout preventer valve that sits on top on of the well and then inject cement to seal it.
Planning was still in its infancy and he was waiting further analysis from BP before making a final decision, Allen said, stressing that the relief well was still the ultimate fix.
The latest estimate for when the relief well will intercept the leaking well is July 29 and the plugging operation would then take place by mid-August.
Gulf residents, who have seen the crude tarnish their shorelines and cripple the local economy since a rig leased by BP exploded and killed 11 workers on April 20, are desperate for a permanent fix so they clean up and start to rebuild.
Kenneth Feinberg, who manages BP’s 20-billion-dollar compensation fund, said capping the well would allow compensation claims to move forward more quickly as the extent of the damage becomes clearer.
