oil spill in gulf, take the cap off and replace with collar with Y's and vales for oil and gas. Tech Ed Inst.?

why isn’t there a shut off vale at the base of each drilling.

    There is. This one got damaged and was the only one. European legislation demands that there be a backup. American legislation on the matter doesn’t exist.

    I wish I had someones cell phone number for you out there. What the hell? Seeing how clueless they seem to be, maybe you just might stun them with the answer. Who knows?

    There is a shut off valve and its called a well head or blowout preventor. This one didn’t work due to a lot of different things that came together at the same time. Sucks to be BP and Trans Ocean right now.

    The problem with attaching anything that shuts off the flow from the well is the pressure pushing the oil out of the hole. I hear that BP is concerned about the integrity of the well bore or formation on the outside of the casing they had just set and cemented. If they shut in the well without having killed the well then you could have an underground blowout. With an underground blowout you would have oil coming up out of the sea floor in several location and then only the relief wells, that they are currently drilling, would be the way to get the flow under control.

    You suggest using a collar with Y’s and valves to get the well under control, I think they could go in with some sort of packer on drill pipe through the well head and set it some where below the well head. Then try pumping heavy kill fluid down through the packer to try to kill the well. If the well was killed you could then pump cement on top of the packer and change out the well head for one that actually works. Then come back and rework the well for production. If you couldn’t get the well undercontrol below the packer then you could always have valves at the surface to control the amount of oil being allowed to flow from the well the pipe that is connected to the packer. Either way you have to consider the amount of pressure coming from the hole and would either action cause an underground blowout or would it exceed the burst limits on the pipe going from the well head to the surface equipment.
