Up to this point on the Deepwater Horizon Oil Rig Failure, BP and the Obama Whitehouse have done a great job in trying to plug the oil well leak contrary to the extremely poor job they have done in protecting the Gulf ecology from leaked oil. Yet they are foolishly gambling this one positive they have with their plan to use the new cap as a plug on the leaking well! What is being referred to here is in the past week BP has removed the cap on the leaking well in the Gulf, the cap that was sitting on the riser pipe coming out of the blowout preventer that was siphoning oil to tankers on the ocean surface. BP after removing this cap unfastend the riser pipe from the top of the blowout preventer and installed a new cap right on the top of the preventer which (this being a magnificant development) fits tightly on the exit pipe protruding from the top of the preventer. With this new cap BP and the White House could now siphon all the oil leaking from the well to the tanker ships on the ocean surface, they have hit a home run why mess this up with this additional "use cap as plug" plan. This additional plan is specifically to use this new cap like a plug, that is, as they close the vents on the new cap they won't be siphoning oil from the cap to tankers but rather just close the cap's vents and use the cap like a plug on the well. This using the cap like a plug is unnecessarily risky because pressure will build up in the well when they take this action and could create other leaks through the oil well pipe in the ocean floor causing leaks that will emanate from the ocean floor that BP will not be able to siphon off and thus not be able to stop from causing ecological damage in the gulf. Even though the plan is to monitor the pressure in the new cap as BP closes the vents for drops in pressure that would signal a leak below the cap so they could start siphoning from the new cap to reduce the pressure and thus reduce the extent of this leak(s) from below the cap this plan is foolishly and unnecessarily risky, in another month at least one of the relief wells almost certainly will have reached the leaking well and facilitated the creation of a cement plug for this leaking well. What is uncontrovertably clear from media accounts of construction of this "Macondo" well is that for the portion of the well right below the ocean floor the well construction work was poorly done and improperly done, good judgement clearly calls for the conclusion that the cement work in between the well casing and the well pipe in this area cannot be classified as reliable, the condition of this cement work is unknown! So why is BP and the Whitehouse taking steps that rely on the integrity of this cement job which using the cap as a plug does, it is absolute foolishness! This cement may not fail quickly, it may fail slowly not setting off pressure alarms vis-a-vis pressure monitoring in the new cap and once it does fail and the subsequent new leak created finds a path to the surface of the ocean floor the game is over so to speak the damage to the ecology will not be able to be stopped. If BP uses this new cap like a plug causing high pressure to build-up in the well pipe and the blowout preventer and say what if their is a seismic disturbance (earthquake) in the well area this disturbance with the high pressure could easily cause a new leak in the well which would not be easy or possible to stop or mitigate! If one was cynical one could allege that the White House here was pursuing using the new cap as a plug for a "Public Relations" victory, in other words so they could tout to the American people they have plugged the oil well leak! If this is what their doing I hope luck is on their side because if it isn't and a new leak or leaks results it is a really lousy situation their leaving to the people of the Gulf!
